Topics in this chapter include: 7750 SR-a Chassis Features on page 7750 SR-a Modules on page 7750 SR-a Chassis Components on page SR-a System Installation Process on page SR-a and SR-a8 Installation Guide

24 7750 SR-a Chassis Features 7750 SR-a Chassis Features The 7750 SR-a family of routers has two chassis models: the 7750 SR-a and 7750 SR-a8. Both chassis are designed for a 9-in. (8.6 mm wide by 00 mm deep) EIA-0 rack with universal spacing. The chassis can also be installed in an ETSI 600 mm wide by 00 mm deep rack using the adapter brackets that are included with the chassis. Each 7750 SR-a and 7750 SR-a8 router chassis is shipped with a backplane, card cage, and factory-installed air filter. Mounting brackets for the chassis are integrated so that the chassis can be mounted in a standard EIA-0 rack. The AC or DC PSU, CPM-a, IOM-a, MDA-a, and fan tray components are packaged and shipped separately. Impedance panels, which are ordered separately, are required to cover empty slots to ensure cooling, for EMI containment during operation, and to prevent dust accumulation. The chassis can be installed horizontally or vertically in the rack. In a horizontal installation, card slots are oriented horizontally; the fan tray and air filter are oriented vertically, and the airflow is side to side. In a vertical installation, card slots are oriented vertically; the fan tray and air filter are oriented horizontally, and the airflow is front to back. A vertical installation requires the Vertical Rack Mount Kit (HE09608AA), which is sold separately. Refer to the Vertical Rack Mount Kit Installation Guide (HE09AAAA TQZZA Edition 0) for information about how to mount the 7750 SR-a and 7750 SR-a8 routers vertically. Access to all 7750 SR-a components is from the front of the chassis. See the following subsections for more information about each chassis SR-a Chassis Features on page 7750 SR-a8 Chassis Features on page SR-a Chassis Features The 7750 SR-a is a 00 Gb/s full-duplex system that is designed to be installed in a 9-in. EIA-0 rack with universal spacing. The chassis occupies 5 RU when installed horizontally. Figure shows the front view of a fully populated 7750 SR-a chassis. Table describes the features of the 7750 SR-a chassis. The chassis can also be installed in an ETSI 600 mm wide by 00 mm deep rack. Adapter brackets are required to accommodate the 55-mm mounting width aperture of the ETSI rack. The 7750 SR-a occupies 9 ETSI RU SR-a and SR-a8 Installation Guide

PSU Redundancy Up to four PSUs can be installed in the front of each chassis. The chassis can support a mix of AC and DC power supplies. For the 7750 SR-a, one PSU can support the full system power requirements if you are operating without power redundancy. For redundancy, at least two PSUs must be installed and powered at all times SR-a and SR-a8 Installation Guide 9

40 7750 SR-a Chassis Components Note: For most applications, one PSU can power a 7750 SR-a system. However, Alcatel-Lucent recommends that you calculate the maximum power consumption of all components in the chassis and install a second PSU, as required. For the 7750 SR-a8, two PSUs are required to support the full system power requirements if you are operating without power redundancy. Three PSUs must be installed and powered at all times for (N + ) redundancy. All unused PSU slots must be filled with impedance panels to maintain EMI containment and proper air flow within the chassis. Cooling System The cooling system is designed to keep the internal components within the acceptable temperature range. The cooling system for the 7750 SR-a and 7750 SR-a8 has the following components: one fan tray one air filter with a reusable metal carrier and a field replaceable filter chassis right-side air intake and left-side exhaust Fan Trays The 7750 SR-a system is cooled by variable-speed fans housed in a fan tray. Air is pulled through the system from a right-side filtered-intake vent, through the chassis and across the line components, then exits through the fan tray in the left of the chassis. The fan speed is reduced at normal temperatures and gradually increases up to its maximum speed as the ambient temperature increases. The fan trays are energy efficient and comply with NEBS acoustic requirements. Fan trays are chassis-specific and described in Table 8. Table 8: Fan Trays Chassis Variant Part Number 7750 SR-a FAN SRa Fan Tray (four axial fans) HE0997AA 7750 SR-a8 FAN SRa8 Fan Tray (six axial fans) HE0998AA SR-a and SR-a8 Installation Guide

42 7750 SR-a Chassis Components The fans are controlled by the system software, and their speed is set according to the environmental temperature surrounding the router. Allow at least in. (7.6 cm) of clearance on each side of the rack to ensure adequate air intake and exhaust. The fan LED located on the front panel of the fan tray indicates the tray status: normal online (green), fault (amber), or offline (not lit if there is no power to the fans). See Fan Tray LEDs on page 0 for more information. There are no field replaceable parts in the fan tray. The entire fan tray must be replaced if a component, such as a single fan, fails. See Removing and Replacing a Fan Tray on page 85 for more information. Fan trays must always be installed and fully operational while the 7750 SR-a chassis is powered. Air Filters Air filters are chassis specific: The 7750 SR-a chassis requires the 7750 SR-a filter. The 7750 SR-a8 chassis requires the 7750 SR-a8 filter. Each chassis has one air filter slot that is located on the right side of the front panel. The air filter has two parts: a reusable metal carrier, and a field replaceable filter. The reusable carrier and one air filter are shipped installed in the chassis. Figure shows an example of the air filter on the 7750 SR-a SR-a and SR-a8 Installation Guide

61 Site Preparation Safety Considerations This section contains safety information about the following: Placement on page 6 Grounding on page 6 Cabling on page 6 Power on page 6 Fan Tray on page 66 Air Filter on page 67 Storage on page 67 Placement Danger: Verify that the rack is correctly bolted, braced, and grounded to a grounding electrode. Warning: Install the 7750 SR-a chassis in a clean, dry, ventilated, and temperature-controlled room. Install the chassis in the equipment rack before installing the components SR-a and SR-a8 Installation Guide 6

62 Safety Considerations Grounding Danger: AC powered units Chassis ground cables are not included. Use only power cords that have a grounding (earthing) path. Main grounding (earthing) connection points are through the IEC600 appliance inlets. Grounding (earthing) points on the sides of the equipment are for equipotential bonding only and are safety grounding (earthing) points for the equipment. Lack of correct grounding (earthing) of the equipment may result in a safety hazard and excessive electromagnetic emissions. The ground conductor must be #8 AWG minimum or the same AWG as the power conductors if they are larger. The router and equipment rack must be correctly grounded. If you ground the equipment by a method other than those provided in this manual, that method should be in compliance with all local wiring regulations and practices. Warning: Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle strap in contact with bare skin. Always connect the ESD strap (with banana plug) to the ESD connection socket (grounding jack) on the front of the chassis. An ESD strap is included in the accessory box that is shipped with the chassis. Danger: DC powered units The 7750 SR-a includes a terminal for chassis ground on the front of the chassis. For both AC- and DC-powered deployments, the ground terminal must be connected. Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel board that serves the DC circuit. Switch the circuit breaker to the OFF position. For extra safety, you can tape the handle of the circuit breaker to the OFF position. When wiring the unit, the ground connection must always be made first and disconnected last. The correct wiring sequence is -V BAT/negative to -V BAT/negative and 0V RTN/positive to 0V RTN/positive. The router is suitable for installation as part of the Common Bonding Network (CBN) or an Isolated Bonding Network (IBN). The router is suitable for installation in Network Telecommunication Facilities or locations where the NEC applies SR-a and SR-a8 Installation Guide

63 Site Preparation For information about grounding the chassis and connecting the AC or DC supply, see Chassis Ground Wiring on page 85; Installing, Wiring, and Connecting an AC PSU on page 9; and Installing, Wiring, and Connecting a 8 VDC PSU on page 98. Cabling Warning: To comply with the GR-089-CORE, Issue 06, requirement R-9 [] standard for electromagnetic compatibility and safety, all intra-building ports are specified for use with shielded and grounded cables at both ends. Intrabuilding ports of the equipment or subassembly are suitable for connection to intrabuilding or unexposed wiring or cabling only. Intrabuilding ports of the equipment or subassembly must not be metallically connected to interfaces that connect to the Outside Plant (OSP) or its wiring or to equipment in an Isolated Bonding Network (IBN) unless the wiring passes through an SPCW as defined in GR-95. These interfaces are designed for use as intrabuilding interfaces only (Type or Type ports as described in GR-089-CORE, Issue 06) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. For equipment installed in an IBN, use Mesh-BN, Mesh-IBN, or Chain-IBN. Equipment rearrangements shall maintain the existing bonding topology. Bare conductors must be coated with an appropriate antioxidant compound before crimp connections are made. All unplated connectors, braided strap, and bus bars must be brought to a bright finish, then coated with an antioxidant before they are connected. The 7750 SR-a is suitable for use in DC-I, DC-C, or AC powered installations. There are no connections between the battery returns and the chassis ground within the 7750 SR-a SR-a and SR-a8 Installation Guide 6

64 Safety Considerations Power Danger: Only trained and qualified electrical service personnel should perform wiring and cabling to the system. All power to the equipment rack or cabinet should be disconnected before the installation. The power cables must be copper and meet your local electric code requirements. The circuit breaker is not intended to be used as the chassis ON/OFF switch. Disconnect the power from the power source to remove power. The 7750 SR-a routers with DC PSU modules should be installed only in restricted access areas (such as dedicated equipment rooms and electrical closets). An external circuit breaker no greater than 60 A must be located within a readily accessible distance of the equipment. This is intended as the disconnect device. DC Power Requirements A disconnect device must be provided within 9.8 ft ( m) of the 7750 SR-a chassis. A #8 AWG (maximum) power conductor must be provided for each of the DC input connections. AC Power Cord Requirements by Country The following AC power cord requirements are applicable to all countries: The length of the power cord must be at least 6 ft (.8 m) and a maximum of 9.75 ft (.0 m).

Topics in this chapter include: Warnings and Notes on page 9 Installing, Wiring, and Connecting an AC PSU on page 9 Installing, Wiring, and Connecting a 8 VDC PSU on page SR-a and SR-a8 Installation Guide 9

92 Warnings and Notes Warnings and Notes Danger: Only trained and qualified personnel should install or replace this equipment and connect the power cables. Confirm that the DC power source is OFF during installation. The power source should be a safety extra-low voltage (SELV) source. Turn off power at the power source before you install or remove power cords. Before working on equipment that is connected to power, remove jewelry, such as rings, necklaces, and watches. When metal objects are in contact with power and ground, serious burns can occur or the objects can be welded to the terminals. Make all ground connections first. The router and equipment rack must be correctly grounded. You must use power cables that meet the local electrical code requirements. This product relies on the building s installation for short-circuit (overcurrent) protection. For AC powered systems, ensure that a circuit breaker, or other equivalent means, rated 0 A, is used in the building s AC branch circuit for the current carrying conductors. For DC powered systems, the unit should be connected to a DC branch circuit with a maximum 60 A circuit breaker that meets the requirements for branch circuit protection. A suitable disconnect device must be provided in the DC branch, either a circuit breaker or switch that can disconnect power from the system during servicing. Warning: Impedance panels are required in all empty slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins. Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis. Do not install equipment that appears to be damaged SR-a and SR-a8 Installation Guide

93 Installing PSUs Note: The 7750 SR-a chassis requires a minimum of one PSU to operate, but two are recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two PSUs to operate, but four are recommended for redundancy. For full redundancy, each PSU module should be attached to an independent power source with a dedicated circuit breaker. A fully redundant system must be connected to both DC PSU modules, or both AC PSU modules, or one DC and one AC PSU module. In the event of a PSU module failure, the entire AC or DC PSU must be replaced. There are no field-serviceable parts inside the PSU. Empty PSU slots in the chassis must be covered by impedance panels. Panels must be ordered separately. See Impedance Panels on page for more information SR-a and SR-a8 Installation Guide 9

96 Installing, Wiring, and Connecting an AC PSU AC-Input Power Supply Guidelines Danger: The AC power cord is not supplied and must be ordered to comply with local country codes and the intended voltage. When applying power to the chassis, be sure to use an approved AC power cord set, and ensure that you do not use any other product's AC power cord set. AC units are rated 00-0 V or 00-0 V. For 00-0 V, you must use a cord rated for a minimum of A. For 00-0 V, you must use a cord rated for a minimum of 0 A. For AC powered units, use only power cords that have a grounding (earthing) path. Main grounding (earthing) connection points are through the IEC600 appliance inlets. Grounding (earthing) points on the front of the equipment are for equipotential bonding only and are not the safety grounding (earthing) points for the equipment. Lack of correct grounding (earthing) of the equipment may result in a safety hazard and excessive electromagnetic emissions. Warning: If you ground the equipment by a method other than those provided in this manual, that method should be in compliance with all local wiring regulations and practices. In order to comply with the GR-089 Lightning Criteria for Equipment Interfacing With AC Power Ports, an external Surge Protective Device is intended to be used at the AC input of the router. Note: To facilitate power redundancy, you must connect all PSU modules to an appropriate source (see DC-Input Power Supply Guidelines on page 00.) Connecting the AC Power Cord to the PSU There is one input AC power cord receptacle for each AC PSU. The AC PSU has an AC plug inlet to accept an AC power cord. The other end of the AC power cord must have a plug that can fit into the power source receptacle that is standard for your geographic region. Figure 8 shows how to connect the AC power cord. Table describes the connections SR-a and SR-a8 Installation Guide

126 Powering Up the 7750 SR-a Powering Up the 7750 SR-a The 7750 SR-a and 7750 SR-a8 do not have a power switch or internal circuit breaker to turn the power ON or OFF: For AC power, power is supplied from an AC power outlet. For 8 VDC power, the 7750 SR-a system DC power is supplied by a DC branch circuit. Danger: You must comply with the general safety precautions and product requirements described in Site Preparation on page 7 and the requirements described in Installing PSUs on page 9 before performing the procedures contained in this chapter. Do not power up a 7750 SR-a before verifying that all common equipment (chassis, power, cooling, and grounding) is connected correctly. Always keep your fingers away from rotating fan blades. Do not put your fingers or any tool in the fan tray if the fans are still spinning. Warning: For correct thermal operation, ensure that Impedance panels are installed in all empty slots before powering up the 7750 SR-a. Note: You must complete the procedure Installing, Wiring, and Connecting an AC PSU on page 9 (for systems using an AC power source) or Installing, Wiring, and Connecting a 8 VDC PSU on page 98 (for systems using a DC power source), and the procedures in Installing Components on page 07 before proceeding with the power-up and initialization procedure. The primary copy of the 7750 SR-a TiMOS software is located on the compact flash memory card that must be installed on the CPM, as described in Installing the Internal CF Card on the CPM-a on page. At power up, the fans initially run at full speed. Thereafter, the control system reduces the fan speed based on temperature. During normal operation, fans never turn off completely. Power-Up To power-up an AC powered system: SR-a and SR-a8 Installation Guide

127 Powering Up, Initializing, and Configuring Step. Step. To initiate the boot process, plug the male end of the power cord into a -terminal, single-phase power source that provides power within the acceptable range, as described in Site Preparation on page 7. Check that the LED on each PSU is green. A green LED indicates that the AC standby and main power supply outputs are operating within specification. If the LED is off, there is no power input. Refer to 7750 SR-a AC PSU LED and Connectors on page 8 for more information. To power-up a DC powered system: Step. Step. Turn on the power at the remote power sources to initiate the boot process. Check that the LED on each PSU is green. A green LED indicates that the DC standby and main power supply outputs are operating within specification. If the LED is off, there is no power input. Refer to 7750 SR-a 8 VDC PSU LED and Connectors on page 9 for more information. Component LED Verification To verify that the components power up correctly: Step. Step. Verify that the system is initializing. The system searches the CF card on the CPM for the boot.ldr file (also known as the bootstrap or boot loader file). The us LED on the CPM-a slowly blinks green during initialization. After initialization (approximately 0 s), the us LED on the active CPM turns solid green to indicate that the CPM boot/load process is complete and that the CPM-a is operational as the primary CPM. The us LED on the inactive secondary CPM-a rapidly blinks green to indicate that the CPM-a boot/load process is complete and that the CPM-a is operational as the secondary CPM-a. If the LEDs do not operate as described above, or if they blink and turn off, refer to Troubleshooting Initial Startup on page. Verify the operational status of the router components by checking all the LEDs on the CPM-a, IOM-a, fan tray and MDA-a components.

134 Troubleshooting Initial Startup Troubleshooting Initial Startup If the us LED does not light after 0 s, as described in Component LED Verification on page 7, the compact flash card is most likely faulty. If the system cannot load or cannot find the boot.ldr file on the cf: slot, the us LED on the CPM turns off and the system checks for a manual boot sequence interruption. Perform a manual boot sequence interruption by connecting a terminal to a Console port and pressing any key when prompted by the display. Unless an unsuccessful system initialization is manually interrupted, the system will continuously reboot in an attempt to successfully find and load the boot.ldr file. Insert a compact flash card with the appropriate boot.ldr file into the cf: slot, as described in Replacing the Internal Compact Flash Card on the CPMa on page 95. When the system finds the boot.ldr file, the system processes the initialization parameters from the BOF. The BOF must be on the same drive as the boot loader file. If the BOF cannot be found or loaded, the system prompts for a different image and configuration location. When the image is successfully loaded, control is passed from the boot loader file to the image. The runtime image attempts to locate the configuration file as configured in the BOF. The configuration file include chassis, IOM-a, MDA-a, and port configurations, as well as system, routing, and service configurations. The following example shows the output when either no flash is present or the boot.ldr file cannot be found. Example: Rebooting display Rebooting... Alcatel 7xxx Boot ROM. Copyright Alcatel-Lucent.

135 Powering Up, Initializing, and Configuring No disk in cf Error - file boot.ldr not found on any drive Please insert CF containing boot.ldr. Rebooting in 5 seconds. Rebooting... When the system finds the boot.ldr file, the system processes the initialization parameters from the BOF (boot option file). The BOF should be on the same drive as the boot.ldr file. If the BOF cannot be found or loaded, then the system prompts the user for alternate software and configuration file locations. When the system software is successfully loaded, control is passed from the boot loader file to the system software. The system software attempts to locate the configuration file as configured in the BOF. The configuration file includes chassis, CPM-a, IOM-a, MDA-a, and port configurations, as well as system, routing, and service configurations. It is important that cables connected to the Console port on the 7750 SR-a chassis are correctly terminated and terminal servers should be correctly configured so as to not negatively affect the functioning of the node. Noisy lines can be interpreted by the node as keystrokes and could interrupt the boot sequence resulting in an outage. After reboot, the CPM can go into a continuous reboot cycle if the boot process is interrupted by random characters received on the Console port. To prevent random characters received on the Console port, terminate all console connections. If a terminal server is connected to the 7750 SR-a CPM-a ensure that it is configured to not send unwanted characters to the CPM-a that could interrupt the boot cycle. For example, configure a no exec or equivalent CLI command on the terminal server SR-a and SR-a8 Installation Guide 5

167 Appendix B: MDA-a and MDA-aXP Card Descriptions Table 8: -port GigE CSFP/SFP MDA-a Description (Continued) Key Label/Part Description 7 Ports Sixteen Gigabit Ethernet SFP ports, numbered 5 to 0 The ports are aligned in two rows as follows: Top row ports 5-6, 9-0, -, 7-8 Bottom row ports 7-8, -, 5-6, Ports Four Gigabit Ethernet SFP ports, numbered to The ports are aligned in two rows as follows: Top row ports - Bottom row ports - 9 MDA-a model -GB-CSFP-SFP Port Allocation The type of modules that you install affects the numbering of the allocated ports. One dual-port-csfp occupies one slot and two ports. If all slots have dual-port CSFPs installed, -ports are allocated. The card requires CSFPs for full -port operation. One single-port SFP occupies one slot and one port. Single-port SFPs use one odd-numbered port when plugged into a CSPF slot. If all slots have single-port SFPs installed, ports are allocated as,, 5...,. The card also supports a mixed configuration of CFSPs and SFPs. If you install a mix of single-port and dual-port (CSFP) modules, the allocated port numbers will be non-consecutive. For example, if the first and fourth modules are dual-port CSPFs and the second and third modules are SFPs, the following ports are used,,, 5, 7, 8. Port Line Rate The GigE CSFP/SFP MDA-a card is an oversubscribed 5 Gb/s MDA-a. The card s connection to the IOM is only 5 Gb/s. The card supports Gb/s line rate out of each port only if 5 or fewer ports are in use SR-a and SR-a8 Installation Guide 67

168 -port GigE CSFP/SFP MDA-a Overview If more than 5 ports are in use, the per-port maximum simultaneous line rates diminishes as a ratio of 5 Gb/s divided by the number of ports in use. For example, if all ports are installed and are run at full speed, the line rate is approximately 5 Gb/s divided by ports, which is 560 Mb/s per port. The card is limited to 5 Gb/s; installing the card in a 00 Gb/s slot does not increase the throughput.

172 Removing and Replacing a PSU Removing and Replacing a PSU This section includes information about: Warnings and Notes on page 7 Removing an AC PSU on page 7 Replacing an AC PSU on page 75 Removing a 8 VDC PSU on page 78 Replacing a 8 VDC PSU on page 8 Warnings and Notes Danger: Make the ground connections first. Only trained and qualified personnel should install or replace this equipment and connect the power cables. External power must be disconnected at the power source. Disconnect and unplug the power cables before you remove and replace a PSU module. You must use power cables that meet local electrical code requirements. Warning: Do not install equipment that appears to be damaged. Impedance panels are required in all empty slots to prevent excess dust accumulation and to help control airflow and electromagnetic interference. Impedance panels do not have board components or connector pins. Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an ESD-preventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis SR-a and SR-a8 Installation Guide

173 Appendix C: Field-Replaceable Units Note: The 7750 SR-a chassis requires a minimum of one PSU to operate, but two are recommended for redundancy. The 7750 SR-a8 chassis requires a minimum of two PSUs to operate, but four are recommended for redundancy. For full redundancy, each PSU module should be attached to an independent power source with a dedicated circuit breaker. A fully redundant system must be connected to both DC PSU modules, or both AC PSU modules, or one DC and one AC PSU module. In the event of a PSU module failure, the entire module must be replaced. There are no field-serviceable parts inside the PSUs SR-a AC PSU If you are operating your 7750 SR-a with redundant PSU modules, you can install, remove, or replace a PSU module without affecting system operation. Danger: Unplug the power cable from the remote power source during the PSU module removal and replacement procedures.

When your system has a critical or major alarm, the CPU causes the alarm relay to issue the alarm output and turn on the critical or major LED. If you push the alarm cut off (ACO) button, the relay will be released but the LED will stay on until the alarm is cleared. Figure 8 shows the DB-5 Alarm Connector. Pinouts are numbered as follows: top row: right to left, pins to 8 bottom row: right to left, pins 9 to 5 Figure 8: DB-5 Receptacle Alarm Connector The system signals the appropriate alarm output for the following events: Fan failure - Critical alarm is raised. One Power Supply Failure - Critical alarm is raised. The critical alarm is cleared and a major alarm is raised if the failed power supply is removed. Chassis temperature threshold exceeded - Major alarm is raised. The system also supports four alarm inputs. The input voltage range is from VDC to 8 VDC. If an alarm input is active, the CPU will process it, output it to the CLI, and issue an SNMP trap. An alarm input can also be configured to activate the appropriate alarm output pin SR-a and SR-a8 Installation Guide 7

219 Appendix D: CPM-a Pinout Assignments RTN refers to the negative side of the Alarm-In connections when a floating power supply is used. If an external power supply is used as the voltage source for Alarm-In -, its negative rail must not be connected to chassis ground and it should be 8 to 50 VDC at 00 ma. When using the internal isolated VDC power supply on pin of the DB5 connector, the Alarm RTN pins must be connected to chassis ground. The metal shell of the alarm plug may be used as a chassis ground connection for the internal + VDC supply providing that the plug mounting (hold down) screws are firmly attached to the alarm connector. Major and Critical alarm dry relay contact outputs are provided on pins, 0,, and,, 9. These reflect the Major and Critical alarms output by the chassis and can be manually cleared by pressing the ACO button. The four alarm inputs are customer configurable to monitor alarms provided by additional equipment. See Figure 8. These inputs must use one of the following: the voltage source provided on pin of the DB5 connector a separate isolated DC power supply, rated between 8 to 50 VDC at 00 ma If an external power source is used, its outputs must be isolated from chassis ground, as shown in Figure 8. Do not connect the alarm power supply return to the chassis or rack ground in this scenario.

221 Appendix E: Pluggable Transceivers In This Chapter This chapter describes how to install and replace the following pluggable transceivers in MDA-a or MDA-aXP cards. Small Form Factor Pluggable (SFP and SFP+) Compact Small Form Factor Pluggable (CSFP) C Form Factor Pluggable (CFP) Quad Small Form Factor Pluggable Plus (QSFP+) Topics in this chapter include: Warnings and Notes on page Preparation on page Installation and Replacement of Pluggable Transceivers on page 7750 SR-a and SR-a8 Installation Guide

222 Warnings and Notes Warnings and Notes Danger: Fiber-optic equipment can emit laser or infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber-optic cables are connected to a light source. CFP and QSFP+ pluggable optic modules are very hot while in use. Touch only the captive screws when removing the module. Allow the module to cool before further handling. Warning: Make sure that the safety cap on the transceiver is inserted while you install or remove the SFP, SFP+, CSFP, CFP, or QSFP+ transceivers. Only remove the safety cap when you are ready to attach network cables. Always replace the dust cover when the SFP, SFP+, CSFP, CFP, or QSFP is removed. Use only approved small form factor pluggable (SFP) and compact form factor pluggable (CFP) fiber-optic devices in MDA-a ports. Before using the optics, verify that the optical path is in compliance with the parameters of the optical components. In particular, verify any minimum attenuation requirements for the optics. If minimum attenuation requirements are not met, the optical receiver components may be permanently damaged. Electrostatic discharge (ESD) damage can occur if router components, including SFP, SFP+, CSFP, CFP, and QSFP+ transceivers are mishandled. Always wear an ESDpreventive wrist or ankle strap and always connect an ESD strap to the grounding plug on the front of the chassis. Caution: Always place router components on an antistatic surface. Avoid bending fiber-optic cable beyond its minimum bend radius. Do not exceed the recommended minimum bend radius for fiber-optic cables. AT&T TP specifies.0 in. (5. mm) inside radius for single fibers. Note: Discard SFP, SFP+, CSFP, CFP, and QSFP+ transceivers according to all local laws and regulations. SFP, SFP+, CSFP, CFP, and QSFP+ transceivers can be installed and replaced without disabling the interfaces. SFP, SFP+, CSFP, CFP, and QSFP+ transceivers are keyed to prevent incorrect insertion SR-a and SR-a8 Installation Guide

223 Appendix E: Pluggable Transceivers Preparation Clean the connector on the fiber cable before inserting it into the transceiver to prevent the transfer of small particles and contaminants to the transceiver. If you switch an SFP, SFP+, CSFP, CFP, or QSFP+ from one port to another ensure that you clean the fiber connectors before reinserting them. Apply high standards when inspecting and cleaning fiber connectors. Use a dry cleaning method to clean fiber connectors.to clean the connector, you can either: Wipe the side and end of the ferrule with a lint-free alcohol-dampened cloth. Blow dry the ferrule with compressed air and inspect for lint. Do not insert the compressed air nozzle into the receptacle. Locking Mechanisms SFP, SFP+, CSFP, CFP, and QSFP+ transceivers use different lock and release methods. Possible lock and release mechanisms include: Bail A bar or wire in the front of the transceiver that you use to release the module. SFP, SFP+, and CSFP transceivers use bail-actuated bottom latching. QSFP+ use bail-actuated side latching. Captive screws Fixed screws on both sides of the transceivers. Screws are used on CFP transceivers SR-a and SR-a8 Installation Guide
