Installing A Power Module - H3C S6850-56HF-IM Manual

•
Before installing a power module, make sure the voltage of the power source is as required by
the power module, and the output voltage of the power module is as required by the device.
•
Do not touch any bare cables or terminals on 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.
• To avoid burns, install a power module on the switch in a tank only when the tank is at a low
temperature.
• When you install a power module on the switch in a tank, wear rubber gloves to avoid direct
contact with the coolant.
IMPORTANT:
You can install a power module on the switch either when the switch is already in a tank or after the
switch is removed from the tank.
To install a power module:
1. Unpack the power module and verify that the power module model is correct.
2. Correctly orient the power module with the handle facing towards ports when it is closed.
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.
