Installing a power supply
CAUTION:
• Follow the forward inertia of the power supply when inserting it into the chassis, and make sure that the power
supply has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you encounter a
hard resistance while inserting the power supply, pull out the power supply and insert it again.
• If only one power supply is installed, install a filler module in the empty power supply slot for good ventilation of the
switch.
To install a 650W AC power supply or 650W DC power supply in the switch:
Procedure
1. Wear an ESD wriststrap and make sure it makes good skin contact and is reliably grounded.
2. Unpack the power supply and verify that the power supply model is correct.
3. Correctly orient the power supply with the power supply slot (as shown in Figure 20: Installing a power supply on page
28, grasp the handle of the power supply with one hand and support its bottom with the other, and slide the power
supply slowly along the guide rails into the slot.
The slot is foolproof. If you cannot insert the power supply into the slot, reorient the power supply rather than use
excessive force to push it in.
