Procedure 4-1
Replacing an AC Power Supply
Step
Action
1
Remove the new power supply module from the packaging and inspect it for
damage.
2
For the AC power supply being replaced, unsnap the bail lock latch securing
the power cord to the power supply module and disconnect the power cord
from the receptacle on the faceplate of the supply.
The Input LED on the power supply will turn off.
3
Using a Phillips screwdriver, loosen the captive hold down screw on the right
of the module.
4
Pull the power supply module out of the slot and set it aside.
5
Slide the new power supply module into the empty slot.
6
Using a Phillips screwdriver, secure the module in place using the captive
hold down screw on the right of the module.
7
Plug the AC power cord into the receptacle on the front of the power supply
module. Snap the bail lock latch up over the boot of the cable to lock the cable
into place.
The power supply will turn on.
8
Verify the power supply LEDs. The following LED indications should be
present on the 3930:
•
PSA - Status LED is solid green, Input LED is solid green
•
PSB - Status LED is solid green, Input LED is solid green
•
PWR - solid green
9
Ensure that the power cable is properly dressed to the right and retained in
the cable support bracket to the right of the chassis. This helps relieve the
cord weight from the connector and avoid the inadvertent disconnection of
the power supply cord.
The power supply has now been replaced.
WARNING:
To prevent ESD damage to electronic components, always use an ESD
wrist strap when handling modules.
