Figure 2-3 Installing cage nuts Mounting the device in a rack CAUTION: • Hold the chassis handles to move the device. Do not hold the handle of a fan tray, a power supply, or a module to move the device. Any attempt to carry the device with these parts might cause equipment damage or even bodily injury.
Figure 2-4 Mounting the device 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 device CAUTION: • Grounding the device reliably is crucial to lightning protection and EMI protection. Ground the device 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 removable components available for the device, see H3C S12500R-2L Switch Router 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 device is operating.
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 device comes with a protective blank panel installed over the interface module slots to protect the device 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.
As shown by callout 3 in Figure 3-5, pull the interface module part way out of the slot. Holding the interface module by the front panel with one hand and supporting the bottom with the other, pull the interface module steadily out of the slot along the guide rails. To avoid touching other components in the chassis, keep the interface module parallel to the slot while pulling it out.
The cable management brackets are installed on the two sides of the interface module slots. As a best practice, install cable management brackets after you have installed interface modules. As shown in Figure 3-7, insert the cable management bracket end that has a spring tab into the cable management bracket hole until the bracket has close contact with the hole.
Fasten the captive screws on the fan tray. The recommended torque for the captive screws is 5 kgf-cm (0.49 Nm). 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.
Installing and removing power supplies Installing a power supply CAUTION: The device 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.
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. See callout 1 Figure 3-11.
Figure 3-12 Using a removable cable tie to secure the power cord to the device 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 transceiver modules CAUTION: To prevent particles from entering the ports, install the dust plugs that come with the interface modules in the QSFP+/QSFP28 ports if you are not to install transceiver modules or cables in the ports.
Installing a QSFP+/QSFP28 transceiver module CAUTION: • Read the following instructions before you install a 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 device The first time you access the device, you can only log in to the device through the console port. Use a console cable to connect a console terminal, for example, a PC, to the console port on the device. Connecting the console cable IMPORTANT: •...
The cooling system is working, and you can hear fan rotating noise and feel air being blown out. • The LEDs on the SEU show that the system is operating correctly. For more information about LEDs, see H3C S12500R-2L Switch Router Installation Guide.
