Installing A Power Supply - H3C S9820-64H Manual

Installing a power supply

CAUTION:
• Follow the forward inertia of the power supply when inserting it into the chassis, and make sure
the power supply has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If
you encounter a hard resistance while inserting the power supply, pull out the power supply and
insert it again.
The switch supports shipping with fan trays and power supplies installed. If your switch came with
power supplies preinstalled, skip this section.
The installation procedure is the same for the LSVM1AC650 and LSVM1DC650 power supplies. The
following procedure uses the LSVM1AC650 power supply as an example.
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 Figure2-21.

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 module bottom with the other, slide the power supply
slowly into the slot along the guide rails.
The power supply slot has a disorientation rejection structure. If you cannot insert the power
supply into the slot, re-orient the power supply rather than use excessive force to push it in.
