1020P-TR/1020P-8R
The 1020P-TR/1020P-8R has a redundant 700 watt redundant power supply
confi guration consisting of two hot-swappable 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.
Power Supply Failure
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 Power
On LED on the control panel will turn yellow and remain on until the failed module
has been replaced and the power supply fail alarm will be activated. Replacement
modules can be ordered directly from the manufacturer. The power supply modules
have a hot-swap capability, meaning you can replace the failed module without
powering down the system.
Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The
redundant feature will keep the system up and running while you replace the failed
hot-swap module. Replace with the same model (p/n PWS-701-1R), which can be
ordered directly from the manufacturer.
1. Removing the power supply
First unplug the power cord from the failed power supply module. To remove the
failed power module, fi rst locate the colored release tab (1). Push the tab to the
right (2) and then pull the module straight out with the handle provided (3) (Figure
6-5, single power supply server shown). The power supply wiring was designed to
detach automatically when the module is pulled from the chassis.
2. Installing a new power supply
Replace the failed hot-swap module with an identical power supply module. Simply
push the new module into the power bay until you hear a click. Finish by plugging
the AC power cord back into the module.
