Do not place the power module in a wet area, and prevent liquid from entering the power
module.

To avoid power module damage, do not open the power module. When an internal circuit or
component of the power module fails, contact H3C Support.
Installing a power module
CAUTION:
• Follow the forward inertia of the power module when inserting it into the chassis, and make sure
the power module has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power module gently. If
you encounter a hard resistance while inserting the power module, pull out the power module
and insert it again.
The switch supports shipping with fan trays and power modules installed. If your switch comes with
power modules preinstalled, skip this section.
To install a power module:
1.
Remove the filler panel, if any, from the target power module slot, as shown in Figure2-27.
Figure2-27 Removing a filler panel
2.
Unpack the power module and verify that the power module model is correct.
3.
Correctly orient the power module with the words on the power module upward. Grasping the
handle of the power module with one hand and supporting its bottom with the other, slide the
power module slowly along the guide rails into the slot.
The slot is foolproof. If you cannot insert the power module into the slot, re-orient the power
module rather than use excessive force to push it in.
