Removing A Power Supply - H3C S6825 Series Installation Manual

The installation procedure is the same for different models of power supplies. The following
procedure installs a PSR450-12A power supply.
To install a power supply:
1. Wear an ESD wrist strap 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 lettering on it upward. 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. Make sure the power supply has good contact with the
backplane.
To prevent connector damages, insert the power supply gently. The power supply and power
supply slot have disorientation rejection designs. If you encounter a hard resistance while
inserting the power supply, pull out the power supply and insert it again.

IMPORTANT:
If the target power supply slot has a filler panel installed, first remove the filler panel from the slot (as
shown Figure2-26).

CAUTION:
When the switch has two power supplies in 1+1 redundancy mode, removing one power supply
does not affect the operation of the switch. When the switch has only one power supply installed,
removing the power supply powers off the switch.
