Replacing the Power Supply
Note: The 760W power supply is an N+1 redundant power supply, where N=2. This
power supply comprises three 380W independently powered modules. These
modules may be replaced without removing the cover. The third power supply
provides fail-over redundancy, and is hot-swappable.
If either of the active power supply modules fail, the backup module will take the full
load and allow the system to continue operation without interruption. The PWR Fail
LED will illuminate and remain on until the failed unit has been replaced.
You do not need to shut down the system to replace a power supply unit. The redundant
feature will keep the system up and running while you replace the failed hot-swap unit.
Replace with the same model (Visara p/n 53932-001).
Accessing the 760W Power Supply
Caution: Before removing a power supply module, unplug the AC power cord first from
the AC power source then from the power supply module.
