15 Preparing for installation 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, unplug 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 proper 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 FRUs, including interface cards, power modules, and fan trays, wear an ESD-preventive wrist strap to avoid damaging the units. Examining the installation site The S5120-HI 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 exhaust 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 bottom device from entering the top device. The rack is sturdy enough to support the switch and its accessories. The rack or workbench is well earthed. To ensure proper 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 appropriate temperature and humidity in the equipment room. Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property change of materials, and metal corrosion. 6

16 Cleanness Lasting low relative humidity can cause washer contraction and ESD and bring problems including loose captive 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, see "Appendix A Technical specifications." Dust buildup on the chassis may 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 strict 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 2 S NH Cl EMI All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions: 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. Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes. Laser safety The S5120-HI switches are Class 1 laser devices. 7

17 WARNING! Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber may hurt your eyes. Installation tools Flat-blade screwdriver Phillips screwdriver Long-nose pliers Diagonal cutting pliers Marking pen ESD-preventive wrist strap Blow dryer All these installation tools are user supplied. 8

18 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. Figure 8 Hardware installation flow 9

If you are using the rear grounding point, connect the one-hole lug grounding cable to the rear grounding point as described in "Connecting the rear grounding point to a grounding strip." If not, skip this step. 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 a switch on a workbench: 1. Verify that the workbench is sturdy and well 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. 21

31 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 Grounding the switch by using the AC power cord 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 rear grounding point to a grounding strip IMPORTANT: Orient the grounding cable as shown in Figure 29 so you can easily install or remove power modules. To connect the rear grounding point to a grounding strip: 1. Remove the grounding screw from the rear panel of the switch chassis. 2. Attach the grounding screw to the ring terminal of the grounding cable. 3. Use a screwdriver to fasten the grounding screw into the grounding screw hole. Figure 29 Connecting the grounding cable to the grounding hole of switch (1) Grounding sign (2) Grounding hole (3) Ring terminal (4) Grounding screw (5) Grounding cable 4. Verify that the one-hole lug grounding cable has been securely connected to the rear grounding point. 22

32 5. Remove the hex nut of a grounding post on the grounding strip. 6. Cut the grounding cable as appropriate for connecting to the grounding strip. 7. Peel 5 mm (0.20 in) of insulation sheath by using a wire stripper, and insert the bare metal part through the black insulation covering into the end of the ring terminal supplied with the switch. 8. Secure the metal part of the cable to the ring terminal with a crimper, cover the joint with the insulation covering, and heat the insulation covering with a blow dryer to completely cover the metal part. 9.

34 Grounding the switch by using the AC power cord If the installation site has no grounding strips or earth ground, you ground an AC-powered switch through the PE wire of the power cord. Make sure: The power cord has a PE terminal. The ground contact in the power outlet is securely connected to the ground in the power distribution room or on the AC transformer side. The power cord is securely connected to the power outlet. NOTE: If the ground contact in the power outlet is not connected to the ground, report the problem and reconstruct the grounding system. Figure 33 Grounding through the PE wire of the AC power cord (1) Chassis rear panel (2) Three-wire AC power cable NOTE: To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the grounding strip in the equipment room as long as possible. Installing/removing a fan tray Only the S SC-HI and S SC-HI switches support hot-swappable fan trays. CAUTION: Each of the S SC-HI and S SC-HI switches has only one fan tray slot for the hot-swappable fan tray. To ensure good ventilation, follow these guidelines: Do not operate the switch without a fan tray. If the fan tray has problems during operation, replace it within 2 minutes while the switch is operating. 25

35 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-preventive wrist strap and make sure it makes good skin contact and is well grounded. 2. Unpack the fan tray and verify that the fan tray model is correct. 3. Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other, 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 (see callout 1 in Figure 34). 4. Fasten the captive screw on the fan tray with a Philips screwdriver until the fan tray is securely seated in the chassis (see callout 2 in Figure 34). If the captive screw cannot be tightly fastened, examine the installation of the fan tray. Figure 34 Installing an LSPM1FAN 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 LSPM1FAN fan tray. Removing a fan tray WARNING! Take out the fan tray after the fans completely stop rotating. To avoid an unbalanced fan causing loud noise, do not touch the fans, even if they are not rotating. To remove a fan tray: 1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded. 2. Loosen the captive screw of the fan tray with a Philips screwdriver until it is fully disengaged from the switch chassis. 26

36 3. Grasp the handle of the fan tray with one hand and pull the fan tray part way out the slot. Support the fan tray bottom with the other hand, and pull the fan tray slowly along the guide rails out of the slot. 4. Put away the removed fan tray in an antistatic bag for future use. Installing/removing a power module WARNING! In power redundancy mode, you can replace a power module without powering off the switch but must strictly follow the installation and procedures in Figure 35 and Figure 36 to avoid any bodily injury or damage to the switch. Each of the S5120-HI switches comes with two power modules. You can install one or two power modules as needed. For more information about the power modules available for the switches, see "Appendix B FRUs and compatibility matrixes." Figure 35 Installation procedure Figure 36 Removal procedure Installing 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 while inserting the power module, pull out the power module and insert it again. To install a power module: 1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded. 2. If the power module slot is covered by a filler panel, remove the filler panel first. 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 37). 5. Fasten the captive screws on the power module with a Philips screwdriver to secure the power module in the chassis (see callout 2 in Figure 37). If the captive screw cannot be tightly fastened, examine the installation of the power module. 27

37 NOTE: If you install only one power module, install the filler panel over the empty power module slot for good ventilation.
