6-5 Power Supply: 7044H-82R/7044H-X8R
The 7044H-82R/7044H-X8R has a triple redundant 760 watt redundant
cooling power supply that consists of three 380W power modules. All
three modules are active and share the load of the system (up to 760W
max.). If any of the three modules fail, the other two will continue to
provide up to 760W of power and allow the system to continue running
without interruption.
The power supply modules have an auto-switching capability that enable
them to automatically sense and operate with 100 or 240 volt inputs. The
power modules are PFC (Power Factor Correction) compliant.
Power Supply Failure
If a power supply module fails, an LED in the control panel as well as
one on the back of the failed power module will illuminate to notify you of
a power failure.
Replacing the Power Supply
1. Accessing the power supply
You do not need to power down the system to replace a power module
on the 7044H-82R/7044H-X8R. Power supply modules can be removed
from the back of the chassis; access to the inside is unnecessary.
2. Removing the power supply
First, unplug the power cord from the failed power supply module. Then
press the locking tab on the module and pull the unit completely out.
3. Installing a new power supply module
Replace the failed unit with another unit having the exact same part
number (PWS-0050M). Gently but firmly push the new unit all the way
into the open bay. Secure it to the chassis using the locking tab. Finish
by replacing the chassis left/top cover and then plugging the power cord
back into the new module you just added.
