Removing A Power Supply - H3C S9820-64H Manual

Figure2-22 Installing a power supply (LSVM1AC650)

Removing a power supply

CAUTION:
The switch supports 2+1 or 2+2 power supply redundancy. When the switch is configured with four
power supplies, removing one or two power supplies does not affect the operation of the switch.
When the switch has only two power supplies installed, removing power supplies powers off the
switch or causes power insufficiency.
The removal procedure is the same for the LSVM1AC650 and LSVM1DC650 power supplies.
To remove a power supply:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Remove the power cord connector from the power supply.
A DC power cord connector has locking tabs. Squeeze the tabs on the power cord connector
with your thumb and forefinger, and pull the connector out, as shown in Figure2-23.
3. Hold the handle on the power supply with one hand, pivot the latch on the power supply to the
right with your thumb, and pull the power supply part way out of the slot, as shown in
Figure2-24.
4. Supporting the power supply bottom with one hand, slowly pull the power supply out with the
other hand.
5. Put the removed power supply in an antistatic bag for future use.
6. If you are not to install a new power supply, install a filler panel in the slot to ensure good
ventilation in the switch.
