Installing slide rails Read the signs on the slide rails to identify the front and rear ends of the slide rails. As shown in Figure 3, mark the position on the rack post for installing the slide rail. a. Insert the locating pin at the bottom of the slide rail into the lowest square hole within the 2U space on the rack post.

Figure 4 Installing cage nuts Mounting the switch in a rack CAUTION: • Hold the chassis handles to move the switch. Do not hold the handle of a fan tray, a power module, or a card to move the switch. Any attempt to carry the switch with these parts might cause equipment damage or even bodily injury.

Installing FRUs This section describes the installation procedures for the MPUs, LPUs, fan trays, and power modules. For the compatibility matrix between these modules and the switch models, see H3C S12500X-AF Switch Series Installation Guide. WARNING! Long-time exposure to strong air flow might cause discomfort. As a best practice, do not stand close to the air outlet vents while the switch is operating.
Figure 7 Installing an MPU Removing an MPU As shown by callout 1 in Figure 8, press the latch to release the ejector lever. Holding the ejector lever with one hand and the latch with the other, pull the MPU part out of the slot.
Figure 8 Removing an MPU Installing LPUs CAUTION: A filler panel is provided with the switch. If you are not to install an LPU in a slot, install the filler panel in the slot. The S12500X-AF H LPUs with the dimensions 50 × 433 × 520 mm (1.97 × 17.05 × 20.47 in) are available for the switch.
Installing an LPU The LPU edges and the ejector lever seats on the LPU slots have purple marks. To install an LPU: Orient the LPU with the upside up based on the orientation of characters on the LPU. As shown by callout 1 in Figure 10, hold the LPU by the front panel with one hand and support its bottom with the other.
Installing the filler panel As shown by callout 1 in Figure 11, align the two captive screws on the filler panel with the installation holes on the slot. As shown by callout 2 in Figure 11, fasten the captive screws on the filler panel. Figure 11 Installing the filler panel Installing cable management brackets CAUTION:...
Installing and removing fan trays Follow these restrictions and guidelines when you install a fan tray: • The switch has two fan tray slots: FAN1 and FAN2. Install two fan trays on the switch. • To prevent dust from entering the chassis, keep the filler panels or fan trays in position if the switch is not in use.
Figure 13 Installing a fan tray Removing a fan tray As shown by callout 1 in Figure 14, loosen the captive screws on the fan tray. Squeezing the captive screw at the air vents side with one hand and holding the fan tray handle, pull the fan tray outward until it is disengaged from the chassis.
Figure 14 Removing a fan tray Installing and removing power modules Installing a power module CAUTION: The switch is shipped with the power module slots empty and with four filler panels for the power module slots. If you are not to install a power module in a slot, install a filler panel in the slot to prevent dust from entering the chassis.
Figure 15 Installing a power module Removing a power module CAUTION: Disconnect the power cord from the module before you remove a power module. To remove a power module: Hold the handle on the power module with one hand and pull downward the latch. See callout 1 in Figure Pull the power module part out of the slot.
Connecting the power cord CAUTION: • Power on the switch after you have completed installation. • Make sure each power cord has a separate circuit breaker. • Turn off the circuit breaker before you connect the power cord. Connecting the AC power cord Plug the AC power cord connector into the AC input receptacle of the power module.
Remove the plastic cover over the wiring terminals, and use a Phillips screwdriver to remove the M5 screws. Connect the wire marked with the negative polarity symbol (–) to the negative terminal (–) on the power module. Connect the wire marked with the positive polarity symbol (+) to the positive terminal (+) on the power module.

• The power cord size does not apply to the power distribution cabinet. • Terminals on the power distribution cabinet do not support customization. A DC input terminal block provides eight pairs of terminals. Each pair has the blue terminal for reconnecting the negative lead and the white terminal for reconnecting the positive lead.
(Optional) Installing transceiver modules CAUTION: • To prevent particles from entering the ports, keep the dust plugs in the SFP+/SFP ports if you are not to install transceiver modules or cables in the ports. • To prevent particles from entering the ports, install the dust plugs that come with the LPUs in the QSFP+/QSFP28 ports if you are not to install transceiver modules or cables in the ports.
Connecting an SFP+/QSFP+/QSFP28/QSFP+ to SFP+ cable CAUTION: When you connect a fiber cable, make sure the bend radius of the cable is not less than eight times the fiber diameter. The cables are hot swappable. Use SFP+ cables to connect SFP+ ports, QSFP+ cables to connect QSFP+ ports, QSFP28 cables to connect QSFP28 ports, and QSFP+ to SFP+ cables to connect QSFP+ and SFP+ ports.
Cabling recommendations Routing network cables The cable management brackets are installed on the two sides of the LPU section. As a best practice, route network cables from the left and right sides. Routing power cords When you route power cords, take consideration of the layout of the equipment room, including the locations of the power distribution cabinet, AC power receptacles, and lightning protection box.
Accessing the switch The first time you access the switch you must use a console cable to connect a console terminal, for example, a PC, to the console port on the switch. Connecting the console cable IMPORTANT: • Identify the mark on the console port and make sure you are connecting to the correct port. •...
Viewing switch startup information After the switch is powered on, the configuration terminal output startup information. The output information varies by software versions. The following shows a sample output you will see when the switch starts up: System is starting... Press Ctrl+D to access BASIC-BOOTWARE MENU...
