8 Preparing for installation H3C S5560-EI Switch Series includes the following models: S S-EI. S S-EI. S F-EI. S C-EI. S C-PWR-EI. S C-EI. S C-EI. S C-PWR-EI. S QS-EI. Safety recommendations To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition. Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet cloth or liquid. Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis. Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall. Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction. Connect the yellow-green protection grounding cable before power-on. Make sure the operating voltage is in the required range. To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off. When replacing field replaceable units (FRUs), including expansion cards, power modules, and fan trays, wear an ESD wrist strap to avoid damaging the units. Examining the installation site The S5560-EI switches must be used indoors. You can mount your switch in a rack or on a workbench, but make sure: Adequate clearance is reserved at the air inlet and outlet vents for ventilation. The rack or workbench has a good ventilation system. Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the switch from the cold aisle and exhausts to the hot aisle. Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the neighboring device from entering the device. The rack is sturdy enough to support the switch and its accessories. The rack or workbench is reliably grounded. 1

9 To ensure correct operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections. Temperature/humidity Maintain temperature and humidity in the equipment room as described in "Appendix A Chassis views and technical specifications." Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion. Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure. High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch. For the temperature and humidity requirements of different switch models, see "Technical specifications." Cleanliness Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure. Table 1 Dust concentration limit in the equipment room Substance Dust Concentration limit (particles/m³) 3 x 10 4 (no visible dust on the tabletop over three days) NOTE: Dust diameter 5 μm The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 2. Table 2 Harmful gas limits in the equipment room Gas Maximum concentration (mg/m 3 ) SO H 2S NH Cl EMI All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways: A conduction pattern of capacitance coupling. Inductance coupling. Electromagnetic wave radiation. Common impedance (including the grounding system) coupling. 2

10 To prevent EMI, use the following guidelines: If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid. Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices. Use electromagnetic shielding, for example, shielded interface cables, when necessary. To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors. Laser safety WARNING! The switch is Class 1 laser device. Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber might hurt your eyes. Installation tools Flat-blade screwdriver Phillips screwdriver ESD wrist strap All these installation tools are user supplied. 3

11 Installing the switch CAUTION: Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the chassis, contact H3C for permission. Otherwise, H3C shall not be liable for any consequence. 4

25 Mounting the switch on a workbench IMPORTANT: Ensure good ventilation and 10 cm (3.9 in) of clearance around the chassis for heat dissipation. Avoid placing heavy objects on the switch. To mount the switch on a workbench: 1. Verify that the workbench is sturdy and reliably grounded. 2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth. 3. Attach the rubber feet to the four round holes in the chassis bottom. 4. Place the switch with upside up on the workbench. Grounding the switch WARNING! Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection. The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis ground to the earth so the faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the switch. You can ground the switch in one of the following ways, depending on the grounding conditions available at the installation site: Grounding the switch with a grounding strip Grounding the switch with a grounding conductor buried in the earth ground NOTE: The power and grounding terminals in this section are for illustration only. Grounding the switch with a grounding strip WARNING! Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod. If a grounding strip is available at the installation site, connect the grounding cable to the grounding strip. Connecting the grounding cable to the chassis 1. Remove the grounding screw from the rear panel of the switch chassis. 2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding screw hole. Fasten the screw. IMPORTANT: Orient the grounding cable as shown in Figure 22 so you can easily install or remove the expansion card. 18

Verify that the grounding cable has been securely connected to the rear grounding point. Connecting the grounding cable to a grounding strip (S C-PWR-EI and S C-PWR-EI) 1. Remove the hex nut of a grounding post on the grounding strip. 2. Cut the grounding cable to a length required for connecting to the grounding strip. 3. Attach a ring terminal to the grounding cable: a. Use a wire stripper to strip 5 mm (0.20 in) of insulation off the end of the grounding cable. b. Slide the heat-shrink tubing onto the cable and insert the bare metal part into the end of the ring terminal. c. Use a crimper to secure the metal part of the cable to the ring terminal. d. Slide the heat-shrink tubing down the cable until the tube covers the joint. e. Use a heat gun to shrink the tubing around the cable. Figure 23 Attaching a ring terminal to the grounding cable 4. Connect the ring terminal to the grounding post of the grounding strip, and fasten it with the removed hex nut. 19

Cut the grounding cable to a length required for connecting to the grounding strip. 2. Use a wire stripper to strip 20 mm (0.79 in) of insulation off the end of the grounding cable. Then use needle-nose pliers to bend the bare metal part to the shape as shown in Figure 25. Make sure the bended part can securely attached to the grounding post on the grounding strip. 3. Attach the bended part of the grounding cable to the grounding post and use the hex nut to fasten the bended part to the post. Figure 25 Connecting the grounding cable to the grounding strip (1) Grounding post (2) Grounding strip (3) Grounding cable (4) Hex nut Grounding the switch with a grounding conductor buried in the earth ground If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube into the earth ground to serve as a grounding conductor. The dimensions of the angle iron must be a minimum of mm ( in). The steel tube must be zinc-coated and its wall thickness must be a minimum of 3.5 mm (0.14 in). Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection. 20

Do not power on the switch when it does not have a fan tray or has only one fan tray installed. Make sure slots are installed with fan trays or blank filler panels for the device to operate. If both fan trays fail during operation, replace them within 2 minutes while the switch is operating. If one fan tray fails, perform either of the following tasks: If the ambient temperature is not higher than 27 C (80.6 F), replace the fan tray within 24 hours and make sure the failed fan tray is in position before the replacement. If the ambient temperature is higher than 27 C (80.6 F), replace the fan tray immediately. Only the S F-EI, S C-EI, S C-EI, S C-EI, S C-PWR-EI, S C-PWR-EI, and S QS-EI switches support hot-swappable fan trays. The switch comes with empty fan tray slots. Choose the fan tray models based on the ventilation requirement of the site. The air flow direction varies by fan tray model. The LSPM1FANSA has a blue handle and provides power-to-port air flow. The LSPM1FANSB has a red handle and provides port-to-power air flow. For more information about the fan trays, see "Appendix B FRUs and compatibility matrixes." Installing a fan tray CAUTION: To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again. To install a fan tray: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Unpack the fan tray and verify that the fan tray model is correct. 21

29 3. Grasp the two handles of the fan tray with the side marked TOP facing up, and slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has a firm contact with the backplane. Figure 27 Installing a fan tray IMPORTANT: At the first login to the switch, use the fan prefer-direction command to set the airflow direction of the switch to be the same as the airflow direction of the fan tray. If the fan tray has a different airflow direction than the switch, the system outputs traps and logs to notify you to replace the fan tray. By default, the switch uses the same airflow direction (power-to-port) as the LSPM1FANSA fan tray. Removing a fan tray WARNING! Do not touch conductors or terminals on the fan trays. Do not place the fan tray in a moist place. Prevent liquid from entering the fan tray. Fan trays with faulty internal wiring and conductors require maintenance from maintenance engineers. Do not disassemble the faulty fan trays. Take out the fan tray after the fans completely stop rotating. Do not touch the fans even if the fans stop rotating to avoid affecting fan balance, which might cause loud fan operating noise. To remove a fan tray: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Grasp the two handles of the fan tray, as shown by callout 1 in Figure 28, and pull out the fan tray slowly along the guide rails. 3. Put the removed fan tray in an antistatic bag. 22

30 Figure 28 Removing a fan tray Installing/removing a power module WARNING! In power redundancy mode, you can replace a power module without powering off the switch but you must strictly follow the installation and removal procedures in Figure 29 and Figure 30 to avoid any bodily injury or damage to the switch. CAUTION: Provide a circuit breaker for each power module. Figure 29 Installation procedure Figure 30 Removal procedure Installing a PSR150 power module CAUTION: To prevent damage to the power module or the connectors on the backplane, insert the power module gently. If you encounter a hard resistance when inserting the power module, pull out the power module and insert it again. For the PSR150-A1, and PSR150-D1 power modules, the installation and removal procedures are the same. The following takes the PSR150-A1 power module as an example. 23

31 To install a power module: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Remove the filler panel from the target power module slot as follows: a. Remove the screws on the filler panel. b. Use a flathead screwdriver to remove the filler panel. Figure 31 Removing the filler panel 3. Unpack the power module and verify that the power module model is correct. 4. Correctly orient the power module with the power module slot (use the letters on the power module faceplate for orientation), grasp the handle of the power module with one hand and support its bottom with the other, and slide the power module slowly along the guide rails into the slot (see callout 1 in Figure 32). 5. Fasten the captive screws on the power module with a Phillips screwdriver to secure the power module in the chassis (see callout 2 in Figure 32). If the captive screw cannot be tightly fastened, verify the installation of the power module. 6. Install the filler panel over the empty power module slot to prevent dust and ensure good ventilation if you install only one power module.

Grasp the handle of the power module with one hand and pull it out a little, support the bottom with the other hand, and pull the power module slowly along the guide rails out of the slot. Put away the removed power module in an antistatic bag or the power module package bag for future use. 5. Install the filler panel to prevent dust and ensure good ventilation if no power module is installed in the slot. Installing a PSR360-56A/PSR720-56A/PSR A power module CAUTION: To prevent damage to the power module or the connectors on the backplane, insert the power module gently. If you encounter a hard resistance when inserting the power module, pull out the power module and insert it again. For the PSR360-56A, PSR720-56A and PSR A power modules, the installation and removal procedures are the same. The following takes the PSR720-56A power module as an example. To install a power module: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Remove the filler panel, if any, from the target power module slot. The power module slot filler panel varies by switch model. Follow the methods in Figure 33 or Figure 34 to remove the filler panel. Method 1: Insert the flathead screwdriver through the handle on the front panel and pull out the filler panel gently. Figure 33 Removing the filler panel (1) Method 2: Put your forefinger into the hole in the front panel and pull out the filler panel gently. 25
