Removing a Power Supply
If you are using the Cisco UCS 5108 server chassis with one power supply (this is only supported in earlier
versions of the system software), removing the power supply will cause the servers and chassis to shut
down. If you are using more than two power supplies, and you remove one of them, the servers continue
to operate as long as the other power supplies are sufficient to meet the power requirements of the number
of servers in the chassis.
Caution
Procedure
Step 1
Loosen the captive screw on the front of the power supply.
Step 2
Lift up the power supply
’
s handle to unseat the power supply.
Step 3
Using the lever, pull the power supply from its slot. Place your other hand under the power supply to support
it while you slide it out of the chassis.
Step 4
Install a blank power supply filler panel (N20-CBLKP) if the power supply bay is to remain empty.
Installing and Removing a Power Distribution Unit (PDU)
The Power Distribution Unit should only be replaced by a Cisco certified technician. This section is for
reference only.
Caution
You can not hot swap a PDU (N01-UAC1). The entire chassis will need to be shut down and all power
cords should be unplugged before attempting this procedure.
