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

Removing a power module
CAUTION:
The switch supports 2+1 or 2+2 power module redundancy. When the switch is configured with four
power modules, removing one or two power modules does not affect the operation of the switch.
When the switch has only two power modules installed, removing power modules powers off the
switch or causes power insufficiency.
To remove a power module:
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 module.
