6-5 Power Supply
The 7043L-8R has a triple redundant 600 watt redundant cooling power
supply that consists of three 300W power modules. All three modules are
active and share the load of the system (up to 600W max.). If any of the
three modules fail, the other two will continue to provide up to 600W 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 at a 110 to 240V AC input. They are
also PFC (Power Factor Correction) compliant.
Power Supply Failure
If a power supply module fails, an audible alarm will activate to notify you of
a power failure. The PWR Fail LED and the LED on the back of the power
supply will also illuminate and remain on (until the failed unit has been
replaced).
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 7043L-8R. Remove the left/top chassis cover to access the
power supply for removal.
2. Removing the power supply:
First, unplug the power cord from the failed power supply module. Next,
press the locking tab on the module and then 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. 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 restoring power to the system.
