The chassis has a 500-Watt redundant power supply configuration consisting of two hot-swap
power modules. The power supply modules have an auto-switching capability, which enables
them to automatically sense and operate with a 100V–240V input voltage.
If either of the two power supply modules fail, the other module will take the full load and allow
the system to continue operation without interruption. The Universal Information LED on the
control panel will blink slowly and remain so until the failed module has been replaced (see
"Universal Information LED" on page
capability—that is, you can replace the failed module without powering down the system. Replace
a failed module with the same model.
Use the following steps to replace a power supply module:
1. Unplug the power cord from the failed power supply module.
2. To remove the failed power module, push the release tab (on the back of the power supply)
to the side and then pull the module straight out (see
The power supply wiring was designed to detach automatically when the module is pulled
from the chassis.
3. Replace the failed power module with an identical module.
4. Push the new power supply module into the power bay until you hear a click.
5. Plug the AC power cord back into the new power module.
