EMI, grounding, power supply, ventilation, and space requirements. Reserve a minimum clearance of 1.2 m (3.94 ft) between the switch and walls or other devices. For more information, see H3C S12500X-2L Switch Installation Guide. Installation tools and equipment No installation tools and equipment are provided with the switch. Prepare them yourself as required.
NOTE: Load-bearing flanges of the LSVM1BSR10 slide rails are at the bottom so the slide rails do not occupy rack space. 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 2-2, mark the position on the rack post for installing the slide rail.
Figure 2-2 Installing slide rails (1) Locating pin (2) Mark the cage nuts installation holes (4) Use the provided M6 screws to secure a slide rail (3) Install cage nuts in the marked square holes to the rack post Installing cage nuts for attaching mounting brackets Before mounting the chassis in the rack, install cage nuts on the front rack posts for attaching the mounting brackets by performing the following steps:...
Figure 2-3 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 supply, or a module to move the switch. Any attempt to carry the switch with these parts might cause equipment damage or even bodily injury.
Figure 2-4 Mounting the switch in the rack (1) Slide the chassis into the rack (2) Use the provided M6 screws to secure the mounting brackets to the rack Grounding the switch CAUTION: • Grounding the switch reliably is crucial to lightning protection and EMI protection. Ground the switch reliably before you use it.

This section describes the installation procedures for the supervisor engine units (SEUs, also called MPUs), interface modules, fan trays, and power supplies. For the compatibility matrix between these modules and the switch models, see H3C S12500X-2L Switch Installation Guide. WARNING! Long-time exposure to strong air flow might cause discomfort.
Figure 3-1 Installing an SEU Removing an SEU As shown by callout 1 in Figure 3-2, press the latch to release the ejector lever. Hold the ejector lever to pull the SEU part way out of the slot. See callout 2 in Figure 3-2.
Figure 3-2 Removing an SEU Installing and removing interface modules Removing the protective blank panel WARNING! The protective blank panel is heavy. To avoid bodily injury, use both hands to remove it. The switch comes with a protective blank panel installed over the interface module slots to protect the switch from damage during shipment.
As shown by callout 1 in Figure 3-4, hold the interface module by the front panel with one hand and support its bottom with the other. Slide the interface module steadily into the target slot along the guide rails. Keep the interface module parallel to the slot to avoid touching other components in the chassis.
Figure 3-5 Removing an interface module Installing a filler panel in an empty interface module slot An interface module slot filler panel is provided with the switch. If you are not to install an interface module in an interface module slot, install the filler panel in the slot. To install a filler panel in an empty interface module slot: As shown by callout 1 in Figure...

Figure 3-8 Installing a fan tray Removing a fan tray The following procedure removes the fan tray from the FAN1 slot: As shown by callout 1 in Figure 3-9, 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.
Installing and removing power supplies Installing a power supply CAUTION: The switch comes with a filler panel in each power supply slot. If you are not to install a power supply in a slot, install a filler panel in the slot to prevent dust from entering the chassis. The installation procedure is the same for AC and DC power supplies.
Removing a power supply CAUTION: Before removing a power supply, disconnect the power cord from it. The removal procedure is the same for AC and DC power supplies. The following procedure removes an AC power supply. To remove a power supply: Hold the handle on the power supply with one hand and pull downward the latch.
Figure 3-12 Using a removable cable tie to secure the power cord to the switch Connecting the DC power cord WARNING! • Before connecting the DC power cord, make sure the circuit breakers for both the positive lead (+) and the negative lead (–) are turned off. •...
Figure 3-13 Connecting the DC power cord (Optional) Installing a DC input terminal block You can order an extension cable and a DC input terminal block to supply power to the switch if the following situations exist: • The power distribution cabinet is far away from the switch. •...
Use screws to attach the DC input terminal block to the rack. Figure 3-14 Attaching a DC input terminal block to a rack To connect power wires to a DC input terminal block: As shown by callout 1 in Figure 3-15, insert the wires of the extension cable into the upper-row terminals on the DC input terminal block, and insert the other ends of the wires into the terminals on the power distribution cabinet.
Installing a QSFP+/QSFP28 transceiver module CAUTION: • Read the following instructions before you install an QSFP+/QSFP28 transceiver module. Failure to follow these instructions might cause damage to the module. • Do not remove the dust plug from the QSFP+/QSFP28 transceiver module if you are not to connect an optical fiber to the module.
Cabling recommendations Routing network cables The cable management brackets are installed on the two sides of the interface module 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. •...
