Determine the installation position of the chassis rails based on the distance between the front and the rear rack posts. See Table Align the round holes in one chassis rail with the screw holes in the chassis. See Figure Use M4 screws provided with the switch to attach the chassis rail to the chassis. Repeat the proceeding steps to install the other mounting bracket and chassis rail.
Figure 3 Installing the slide rail (rear view) Mounting the switch in a rack WARNING! • Two persons are required to mount the switch in a rack. • Support the switch bottom from both sides to move the switch. Do not hold the handle of a fan tray, power module, or card to move the switch.

The mounting bracket is 2 RU high. On the left front post, the uppermost, the lowermost, and the two middle installation holes require cage nuts. On the right front post, only the uppermost and lowermost installation holes require cage nuts. See Figure Make sure the uppermost cage nuts on the four rack posts are at the same height.
Use grounding screws to attach the two-hole grounding lug of the grounding cable to the chassis. IMPORTANT: For an S12501X-AF switch, attach the two-hole grounding lug to the chassis as shown in Figure so that the grounding cable is on top of the grounding lug.

Installing FRUs This section describes the installation procedures for the 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.
Installing an LPU with standard ejector levers Orient the LPU with the upside up based on the orientation of the lettering on the LPU. As shown by callout 1 in Figure 8, holding the LPU by the front panel with one hand and supporting its bottom with the other, gently slide the LPU into the slot along the slide rails.
Page 13
As shown by callout 2 in Figure 9, rotate the ejector levers downward to the horizontal position when most of the LPU is inserted into the slot. As shown by callout 3 in Figure 9, rotate the ejector levers outward to the outmost. As shown by callout 4 in Figure 9, continue to push the LPU by its middle part on the front panel...
Installing the filler panel As shown by callout 1 in Figure 10, squeezing the captive screws on the filler panel, insert the filler panel into the slot. As shown by callout 2 in Figure 10, fasten the captive screws on the filler panel. Figure 10 Installing the filler panel Installing and removing fan trays Follow these restrictions and guidelines when you install a fan tray:...
Figure 11 Installing a fan tray Removing a fan tray As shown by callout 2 in Figure 12, grasp the fan tray handles and pull the fan tray out of the slot. Support the fan tray bottom with one hand as you pull the fan tray out of the slot. Place the removed fan tray on an antistatic mat or in an antistatic bag.
To install a power module: Unpack the power module. Make sure the power module model is as required. Orient the power module with the upside down based on the orientation of the lettering on the power module. Holding the power module with one hand on its handle, pulling the latch toward the handle with your thumb, and supporting the bottom of the power module with the other, slide the power module along the slide rails into the slot and release the latch.
Connecting the power cord WARNING! • Power on the switch after you complete installation. • Turn off the circuit breaker before you connect the power cord. CAUTION: Make sure each power cord has a separate circuit breaker. Connecting the AC power cord Plug the AC power cord connector into the AC input receptacle of the power module.
(Optional) Installing a DC input terminal block You can use an extension cable and a DC input terminal block to supply power to the device if the power cord cannot connect to the power distribution box directly. A DC input terminal block provides eight pairs of terminals. Each pair provides one power line reconnection.
(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.
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. •...
Verification before login Before you log in to the switch, perform the following tasks: • Verify that the switch has been correctly installed. • Verify that the card has been correctly installed. • Verify that all the network cables, fibers, power cables, and grounding cables have been correctly connected.
