SUPERWORKSTATION 7033A-T Manual
6-5 Power Supply
The 7033A-T has a single 450W redundant cooling power supply that fea-
tures noise-suppression technology for silent operation. The power supply
has the capability to automatically sense and operate from 100 to 240V AC.
This power supply also has the PFC (Power Factor Correction) feature built
in.
Power Supply Failure
If the primary power supply fan fails an audible alarm will notify you of a
the problem. Disable the alarm by pressing the alarm reset switch on the
back of the power supply. 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:
After powering down the system, you’ll need to remove the left chassis
cover to access the power supply for removal.
2. Removing the power supply:
First, unplug the power cord from the power supply. Then remove the
power supply connectors going to the motherboard and the SATA
backplane. Finally, remove the screws that secure the unit to the mount-
ing brackets in the chassis 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 mounting brackets in the chassis with the screws
provided. Connect the two power cables to the SATA backplane and the
two to the motherboard (ATX PWR CONN and J15 connectors). Finish by
replacing the chassis left cover and then restoring power to the system.
