Installing and removing a power supply

The switch provides two power supply slots. It comes with power supply slot PWR1 empty and power
supply slot PWR2 installed with a filler panel. You can install one or two power supplies for the switch
as required. For the power supplies available for the switch and their specifications, see hardware
information and specifications for the switch series.
WARNING!
• To avoid bodily injury or switch damage, strictly follow the procedures in
Figure2-24
• You must provide a circuit breaker for each power supply.

CAUTION:
• To prevent damage to the power supply and the connectors on the backplane, insert the power
supply gently. If you encounter a hard resistance when inserting the power supply, pull out the
power supply and insert it again. Make sure the power supply has a good contact with the
connectors.
• When the switch has two power supplies working in 1+1 redundancy, removing one power supply
does not affect system operation. If the switch has only one power supply, removing the power
supply causes power down of the switch.
• If you are not to install a new power supply after removing the old one, install a filler panel in the
slot in time.
• Use a torque of 5 kgf-cm (0.49 Nm) to fasten the captive screws on a power supply.
