5 Preface ABOUT THIS MANUAL ADC s Midspan Power over Ethernet (PoE) Controller eliminates the need to run power for IP telephones, wireless LAN Access Points, webcams and other Powered Data Terminal Equipment (PDTE) at the end of the LAN line, without modifing existing Ethernet infrastructure. Installers need to run only a single Ethernet Cat 5, 5E, or 6 cable to carry both power and data to each device. This allows greater flexibility in locating of network devices and significantly decreases installation costs in many cases. ADC s Midspan Power over Ethernet (PoE) Controller is IEEE802.3af compliant. ADC s Midspan Power over Ethernet (PoE) Controller is designed for use within a building not for use with a MAN (Metropolitan Area Network). ADMONISHMENTS Important safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments in the form of Dangers, Warnings, and Cautions must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below) and are listed in descending order of severity of injury or damage and likelihood of occurrence. Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided. Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided. GENERAL SAFETY PRECAUTIONS Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically-powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm.

7 1 INTRODUCTION ADC s PoE is not a data hub or switch. ADC s PoE adds 48VDC to the unused pairs (4/5 and 7/8) of the Ethernet data path that is then fed to power devices. ADC s PoE is designed for use with standard 10Base-T and 100Base-TX Ethernet over 8-wire Cat 5, 5E, or 6 cable. ADC s Power over Ethernet Midspan Controller is available with 8-, 16-, or 24-ports. An optional CPU is available for use when SNMP is required. CPU linecard is hot-swappable allowing card to be inserted into a powered chassis. ADC s PoE normally powers devices that are enabled for power over LAN or are equipped to receive power over Ethernet. These devices are called Powered Devices (PD) or Powered Data Terminal Equipment (PDTE). Devices not equipped to receive power over Ethernet must have local power. 1.1 Power over Ethernet Midspan Controller Features Supply power to remote Ethernet terminals Eliminates the need for AC power at remote Ethernet terminals Universal power input ( VAC 50/60 Hz) 15.4 Watts ( 48 VDC) available to each port Optional SNMP management Up to five chassis may be daisy-chained together using a single IP address for SNMP communications Independent overload and short-circuit protection on each channel Individual port status indicators Standard 19-inch rack mounting (Reversible mounting brackets for 23-inch rack mounting) Replaceable 400W AC-DC power supply 1.2 Power over Ethernet Front View Detail 10Base-T and 100BASE-TX data and power output ports are the upper ones as shown in Figure 1. Each PoE has 8, 16, or 24 data and power ports configured as Media Dependent Interface (MDI) non-crossover. These ports are designed to carry Ethernet data over the standard 2-wire pairs (RJ-45 pins 1/2 and 3/6) and DC power is carried over the spare wire pairs (RJ-45 pins 4/5 and 7/8). 10Base-T and 100BASE-TX data input are the lower ports as shown in Figure 1. All ports are designed to carry Ethernet data only (TX/RX) over the standard 2-wire pairs (RJ-45 pins 1/2 and 3/6). The Com IN port provides two functions. First it is used as a Console port for configuration of the CPU-SNMP linecard. Second it is used as the Com IN port for chassis daisy-chaining. This connector is an industry standard DB-9 receptacle. Com IN port may be used to obtain port status information when there is no CPU SNMP linecard installed. Page 1

8 Com OUT port is used for chassis daisy-chaining only. Com OUT connector is an industry standard DB-9 plug. Any combination of up to five PoE Chassis may be controlled using one IP address and one CPU. Caution: ADC s PoE Midspan Controller is not a repeater. The maximum distance from an Ethernet switch to Data Terminal Equipment (DTE) must not exceed 100 meters (328 ft.). DATA AND POWER PORTS DATA PORTS PORT LEDs COM IN A COM OUT POWER LED Figure 1. PoE Front View 1.3 LEDS LEDs on the front indicate status of the PoE and its ports. One bi-color (green/yellow) LED for each port provides port status. A green port status LED indicates that the network equipment has been identified as Power Over LAN enabled, is active, and sending power. A yellow port status LED indicates that the network equipment has been identified as Power over LAN enabled, but is not sending power. In the event that a piece of Ethernet equipment that is not Power Over LAN enabled is connected to the PoE (indicated by LED being off), the Ethernet equipment is unaffected because power is not being supplied. Table 1 contain ethernet status information as presented by the LED during normal operation. Table 1.

10 2 INSTALLING THE POWER OVER ETHERNET CHASSIS 2.1 Unpacking and Inspection Unpack and inspect the various components as follows: 1. Inspect the exterior of the shipping container(s) for evidence of rough handling that may have damaged the components in the container. 2. Unpack each container while carefully checking the contents for damage and verify with the packing slip. 3. If damage is found or parts are missing, file a claim with the commercial carrier and notify ADC Customer Service. Save the damaged cartons for inspection by the carrier. 4. Refer to Section 12, Customer Information and Assistance if you need to contact ADC. 5. Save all shipping containers for use if the equipment requires shipment at a future date. The following procedures provide the necessary instructions for installing and wiring an Power over Ethernet Chassis in an equipment rack. 2.2 Rack Installation Mounting brackets and mounting screws are shipped loose. Mounting brackets may be positioned for either 19 or 23-inch rack installation. The adjustable mounting brackets allow the chassis to be installed flush with the equipment rack face or at a depth of two-inches. Do not obstruct ventilation vents on the chassis. Caution: When mounting the PoE chassis in the rack make sure mechanical loading is even to avoid a hazardous condition, such as loading heavy equipment in the rack unevenly. The rack should safely support the combined weight of all equipment installed in it. Warning: To prevent electrical shock, never install chassis in a wet location or during a lightning storm. Before making any connections verify that input power source is off (switch in the OFF position or AC plug removed). If PoE chassis is installed in a closed or multi-rack assembly, operating temperature of the rack environment may be greater than the ambient temperature. Install PoE chassis in an environment that is compatible with the maximum rate ambient temperature. See Section 7 Specifications. Caution: Installation of the PoE chassis in a rack without sufficient air flow may result in unsafe operation. Note: Install PoE chassis in the equipment rack so that forced air by the chassis does not compromise safe operation. This procedure provides instructions for installing the chassis in an EIA or WECO 19 or 23- inch equipment rack. Check the work order to determine the chassis location in the rack and the mounting, flush or recessed. Page 4

11 1. Obtain the following tools and equipment: Flat blade or Phillips screwdriver (type to match mounting screws) Locate four binder head machine screws provided. 2. Determine what rack size is being used and what recess is required. When installing in a 19- inch rack use three (6-32 x 0.25 inch screws) provided to attach the wide side of mounting bracket to the chassis (wide side of brackets point to the rear of the chassis and the narrow side of the brackets are perpendicular to the sides of the chassis). See Figure 3. When installing in a 23-inch rack use three (6-32 x 0.25 inch screws) provided to attach narrow side of the mounting bracket to the chassis (narrow side of brackets point to the rear of the chassis and the wide sides of the brackets are perpendicular to the sides of the chassis). Torque these screws to approximately 7 8 pound-inches ( Newton meters) x 0.25 IN. SCREWS (6 PLACES) REVERSIBLE MOUNTING BRACKET (2 PLACES) A Figure 3. Chassis Mounting Bracket Installation for 19-inch Rack 3. Locate the equipment rack mounting space that is specified for the chassis. Note: Total cable distance between switch and data terminal equipment should not exceed 100 meters (328 feet). 4. Place the chassis in the assigned mounting space and align the holes in the mounting brackets with the holes in the equipment rack. See Figure Secure chassis mounting brackets to equipment rack using the inch binder head machine screws provided. Torque screws to approximately 27 pound-inches (3.1 Newton meters). Page 5

12 19624-A MOUNTING SCREWS (2 PLACES EACH SIDE) Figure 4. Installing Chassis 2.3 AC Power Connection Warning: Follow basic electricity safety measures when connecting the PoE to a power source. The PoE chassis should be grounded. Ensure that power source is connected to earth ground during normal use. Warning: This product relies on the building wiring and distribution panels for short-circuit (overcurrent) protection. Make sure a fuse or circuit breaker no larger than 120VAC, 15A. U.S. (240VAC, 10A international) is used at the distribution panel. Warning: When connecting the PoE to the supply circuit, be sure to check PoE nameplate ratings to avoid overloading circuits which may cause damage to over-current protection devices and supply wiring. Note: Be sure to maintain reliable earthing (grounding) for rack mounting equipment. Pay particular attention to supply connections. Verify that power switch on chassis is in the OFF position. Plug one end of power cord into chassis power receptacle and the other end into the AC outlet. 3 POWERING UP Move on/off switch to ON position. PoE powers up and internal fan begins operating. PoE then runs through a power-on self-test, which takes a few seconds. During self-test, all ports on the PoE are disabled and the front panel LEDs light in the following sequence: 1. ON LED lights (green). Page 6

13 2. All Port LEDs and the ON LED light for an LED test (green). 3. All Port LEDs light yellow and the ON LED lights green for an LED test. 4. ON LED lights green and remains lit. 5. All ports are enabled for normal operation and Ports are ready (see Section 1.3, LEDS). 4 ETHERNET CONNECTIONS All PoE front ports are configured as data through ports for all data wires (pins 1, 2, 3, and 6). Be sure to use a standard Cat 5, 5E, or 6 cable including all 8 wires (4 pairs). 4.1 Data & Power Ports Using standard Cat 5, 5E, or 6 straight-through cable, connect cable leading to the remote device to the corresponding Data & Power port. See Table 3 for Data & Power port pinout information. Table 3. Data & Power RJ-45 Pin-Outs PIN FUNCTION PIN FUNCTION 1 TX+ 2 TX 3 RX+ 4 Return 5 Return 6 RX 7 48VDC 8 48VDC Note: Be sure to connect each Data & Power port to the corresponding Data port. 4.2 Data Ports Using a standard Cat 5, 5E, or 6 cable, connect the cable leading from the Ethernet switch or hub to the Data port. See Table 4 for Data port pinout information. Table 4. Data RJ-45 Pin-Outs PIN FUNCTION PIN FUNCTION 1 TX+ 2 TX 3 RX RX COMMUNICATION/DAISY-CHAIN PORTS Com IN communications port on the front panel may be connected to a terminal or PC for local communications to the chassis. When more than one chassis are connected together all Com IN ports (chassis) after the first one become Com IN ports used to support the daisy-chain. Page 7

14 5.1 Com IN Port Figure 1 shows the Com IN port position on the chassis. Com IN port is a DB-9 receptacle style connector providing an RS-232 DCE interface for local communications. Pins two and three are used for data communications and pins one, six, and nine are used for chassis daisy chaining. When this port is connected to a terminal it is called a Console (CON) port. If the chassis is number two, three, four, or five in a daisy-chain this port is referred to as Com IN. This port does not support a modem. This port is used for local access to the chassis and is used to set the initial communication parameters. Shielded cable is recommended and the maximum cable length is 25 feet. A 1:1 cable is required to connect this port to the DTE com port of a PC. Pin out information is shown in Table 5 and Figure 5. Table 5.

In the event of a fan or power supply failure, the modular power supply may be removed from chassis for replacement. Power supply should not be removed while the PoE is in operation. Data transmissions through the PoE are not interrupted when the chassis is powered down. Page 11

18 Replace power supply module as follows: 1. Move power switch to the OFF position. 2. Remove power cord. 3. Loosen the thumb screws on each end of the power supply module. See Figure Remove power supply module by pulling it straight out of the PoE chassis. 5. Carefully slide power supply module into the slot until the board edge connector mates completely with the backplane connector. If excessive resistance is felt, withdraw the module and check for obstructions and proper alignment A POWER SUPPLY THUMB SCREW (2 PLACES) Figure 8. Power Supply Module Thumb Screws 6. Secure power supply module in place by tightening the retaining screws on the module. Be sure screws are properly threaded before tightening. 7. Insert plug into the receptacle on the rear of the power supply module. 8. Move power switch to the ON position. 9 TROUBLESHOOTING This section helps you locate problems related to the PoE setup and functionality. Troubleshooting provides a problem and possible resolutions to assist in locating minor operating problems. If the provided resolutions do not solve your problem, call ADC for further assistance. Page 12

19 If you encounter problems, make sure: Power is applied to the chassis. An input Ethernet cable is connected to the Data port. An output Ethernet cable is connected to the Data & Power port. The input and output cable pairs are attached to corresponding ports. Table 8. Troubleshooting PROBLEM PoE is plugged into a main AC outlet, but does not power up. PoE is plugged in and running, but fan is not working. PoE operates, but AC LED is off. PoE has powered up and ON LED is red. Power supply is operating and rear LED is amber. Port LED on one port is not lit and the corresponding remote device does not operate. RESOLUTION Verify that a correct and functional AC power cord is used, including a good solid ground connection. Verify that AC outlet is supplying power (test with another device) and that voltage is between 100VAC and 240VAC (50Hz/60Hz). Reconnect PoE to AC outlet and verify the LEDs power up sequence. See Section 1.3, LEDS. Verify all fan openings in chassis are clear of any obstructions. If fan is not working, there may be an internal power supply fault. Replace power supply. If internal fan is working, there is a possible internal circuitry fault. If fans are not working, there may be an internal power supply fault. Replace power supply. Check self-test sequence. If LEDs light in the correct sequence, PoE is fully operational. If problem remains following self-test sequence, PoE self-test detected an internal fault. Contact ADC. Power supply has exceeded the maximum operating temperature and will shut down. Verify all fan openings in chassis are clear of any obstructions. If fan is not working, there may be an internal power supply fault. If internal fan is working (that is, air flows out of the chassis or can be heard), there is a possible internal circuitry fault. Replace power supply. PoE did not detect a connected remote device, therefore port is not providing power. Verify that: Remote device is Power Over LAN enabled. Verify that you are using a standard UTP Category 5, 5E, or 6 cable, including all 8 wires (4 pairs). If an external splitter is in use, replace it with a new splitter. Discard faulty splitter. Remote device is connected to the Data & Power port (upper RJ-45 connector). In addition, try to: Re-connect the same remote device to a different port on the same unit. If it works, there is probably a faulty port or RJ-45 connection. Bypass the long twisted pair cable and move remote device closer to PoE and connect to one of the ports using a short cable. If this works, most likely there is a faulty connection or short on the long cable, or a bad RJ-45 connection in the line. Try powering it up again and verify a correct power-up LED sequence. Page 13

20 Table 8. Troubleshooting PROBLEM Remote device operates, but there is no data link. One of the ports is powering a remote device without turning Port LED on. Is it safe to keep PoE running while the rear LED is Amber? RESOLUTION Verify that: Port LED on PoE front panel is lit continuously. Data and Data & Power ports correspond. If an external splitter is in use, replace it with a new splitter. Discard faulty splitter. Verify that you are using a standard UTP Category 5, 5E, or 6 cable, including all 8 wires (4 pairs), and is 100m or less in length between switch and remote device. PoE is connected to a switch or hub with a good RJ-45 patch cord connection. In addition, try to: Bypass the long twisted pair cable and move remote device closer to PoE and connect to one of the ports using a short cable. If this works, most likely there is a faulty connection or short on the long cable, or a bad RJ-45 connection along the line. Connect a different remote device to the port. If this works and link is established, there is probably a faulty data link in the remote device. Re-connect remote device to a different Data & Power port and remember to move the Data port of the switch or hub accordingly. If this works, there is probably a faulty Data & Power or Data port in the PoE or a bad RJ-45 connection. Re-connect remote device to a different Data & Power port. If the LED turns on, there is a fault in the previous output port (probably a faulty LED). Yes, this condition is safe for a short period of time. Page 14

21 10 PoE STATUS The on-board PoE micro-controller features a minimum command-line over the serial DB-9 receptacle COM IN port. Chassis status may be viewed by connecting a computer or terminal to this port. Connect a VT-100-compatible host computer to the COM IN port. Set up communications with the chassis. A communications software program or terminal is required to communicate with PoE chassis. Use a DB9 straight through cable to connect the COM IN port to the host terminal or computer. Communication parameters must be set to 9600 baud, Data bits 8, 1 stop bits, no parity and no flow control. At power-up: 1. All port LEDs light yellow, then green, and then port LEDs go to normal mode (green = Powered Device powered, yellow = Powered Device detected, off = no Powered Device connected to the port). 2. PoE status similar to the following is displayed: Type <ENTER> to show status PoE Midspan Unit Version Build 1 Copyright (c)2004 ADC Cat#:PWR24AC P/N: S/N:0002 P/S:OK A/C:OK D/C:OK Fan/Temp:OK Port Detected Class Powered 01 y 0 y 02 y 2 y 04 *SHORT* 05 y 0 y 07 y 1 y 13 y 3 y 20 y 2 y 24 y 1 y Total detected:07/24 Total powered:07/24 The PoE status displays in the following order: Micro-controller firmware version Remote inventory information (ADC catalog number, part number and serial number) Power supply status Port status showing all powered devices (PD) detected, as well as their power classification per IEEE 802.3af. Total ports connected to a powered device (PD), and total ports powered. At any time, press <ENTER> to refresh PoE status. Page 15

22 The unit also displays port status changes: When a PD device is connected to a port, a message similar to the following appears: Port 01: Detected class 0 Port 01: Powered When a PD device is disconnected from a port, a message similar to the following appears: Port 01: ** POWER LOSS Port 01: Detected OPEN When a non-pd device is connected to a port, a message similar to the following appears: Port 04: Detected *SHORT* When a non-pd device is disconnected from a port, a message similar to the following appears: Port 04: Detected OPEN The on-board PoE micro-controller controls and monitors only the local unit. It does not provide control or status for other midspan units that may be daisy-chained to it. In addition: In a daisy-chain environment, only the first unit will feature this command-line (other units down in the daisy-chain have the command-line disabled). Use the optional CPU card in a daisy-chain environment to provide status and control for all daisy-chained units. When the optional CPU card is plugged in, it takes over the serial COM IN port from the on-board micro-controller. The command line interface is disabled. Refer to the CPU command manual. 11 SNMP WEB MANAGEMENT Use of optional CPU linecard provides a 10/100BASE-T Ethernet connection through a RJ-45 jack. Page 16
