Installing A Power Supply - H3C S9825 Series Manual

Installing a power supply

The power supply installation procedure is the same for the switches. The S9855-48CD8D switch is
used as an example in the following figures.
To install a power supply:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Remove the filler panel, if any, from the target power supply slot, as shown in Figure2-30.

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 power supply 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.
CAUTION:
The power supply and the slot form an anti-misalignment structure. If you insert the power
supply into the slot upside down or the power supply is not aligned with the slot correctly, you
will encounter a hard resistance. If this happens, pull out the power supply, orient it correctly,
and then insert it again. Do not insert the power supply forcibly.
