If you insert the power supply into the slot upside down, the power supply output connectors
might be damaged during the inserting or removing process.
If you encounter a hard resistance while inserting the power supply, pull out the power supply,
orient it correctly, and then insert it again. Do not insert the power supply forcibly.

IMPORTANT:
Keep the filler panel for power supply slots and packaging boxes and bags of power supplies secure
for future use.
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.
To remove a power supply:
1.
Turn off the circuit breaker for power input.
2.
Remove the power cord from the power supply.
3.
As shown in Figure2-23, use one hand to hold the power supply handle, press the latch towards
the handle, and then pull the power supply part way out of the slot. Supporting the power supply
with the other hand, pull it completely out of the slot.
4.
Put the removed power supply in an antistatic bag for future use.
5.
If you are not to install a new power supply, install a filler panel in the slot to ensure good
ventilation in the switch.
