Removing A Power Module - H3C S6820 Series Installation Manual

To install a power module:
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
1.
Remove the filler panel, if any, from the target power module slot, as shown in
2.
Figure 34 Removing a filler panel
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. Grasp the
4.
handle of the power module with one hand and support its bottom with the other, and 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.

Removing a power module

CAUTION:
• When an S6820-32H or S6820-56HF switch has two power modules in 1+1 redundancy mode,
removing one power module does not affect the operation of the switch. When the switch has
only one power module installed, removing the power module powers off the switch.
• When an S6820-4C switch has power modules in 2+1 or 2+2 redundancy mode, removing one or
two power modules does not affect the operation of the switch. When the switch has only two
power modules installed, removing power modules powers off the switch or causes power
insufficiency.
The LSVM1AC650 and LSVM1DC650 removal procedure is the same on the S6820 switches. The
figures in this section use the S6820-32H switch as an example.
