3. Unpack the power supply and verify that the power supply model is correct.
4. Correctly orient the power supply with the lettering on it upward. Grasping the power supply
handle with one hand and supporting the module bottom with the other, slide the power supply
slowly into the slot along the guide rails. Make sure the power supply connectors have firm
contact with the backplane.
If you insert the power supply into the slot upside down, the power supply output connectors
might be damaged during the inserting or removing process.
If you encounter a hard resistance while inserting the power supply, pull out the power supply,
orient it correctly, and then insert it again. Do not insert the power supply forcibly.

Removing a power supply

CAUTION:
The switch supports 2+1 or 2+2 power supply redundancy. When the switch is configured with four
power supplies, removing one or two power supplies does not affect the operation of the switch.
When the switch has only two power supplies installed, removing power supplies powers off the
switch or causes power insufficiency.
To remove a power supply:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Remove the power cord from the power supply.
