Hot Swap Power Supplies
Your system uses a dual-redundant hot-swappable power supply. You can
replace a failed power supply module without turning the system off.
Make sure you have a replacement power supply before starting this procedure.
Keep a replacement power supply module on hand, and replace failed modules
promptly. Running on one power supply module for any length of time can
compromise the uninterrupted operation of your system.
Three signals indicate that a power supply module has failed.
• The warning alarm sounds.
• The green LED on the failed power supply module is off.
• The PS FAIL LED on the front of the unit is red.
To stop the alarm from sounding, unplug the power supply module from the
system.
Note:
For redundant operation your system requires two working modules. If
one module fails, replace the failed module immediately.
To replace the
failed power
supply module
1 Put on protective gloves before removing the failed power supply module.
The power supply module is very hot.
2 Pull out the failed power supply module, and put it somewhere where it
will not be touched until it cools down.
3 Insert a replacement power supply module.
4 Confirm that the power supply module LED is green.
5 Confirm that the PS FAIL LED on the front of the unit is off.
6 Snap the power supply module in place.
See “Change the Power Supply” on page 39 for details on replacing a power
supply module.
