Power Supply
The 7034A-T/7034A-i has a single 645W redundant cooling power supply (part#
PWS-0060) that features noise-suppression technology for silent operation. The
power supply has the capability to automatically sense and operate at 100 - 240V
AC. This power supply also has PFC (Power Factor Correction) built in.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to
replace the power supply unit. Replacement units can be ordered directly from
Supermicro (see contact infomation in Chapter 1).
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 serverboard (ATX PWR, PWR2 and
PWR3). Finally, remove the screws that secure the unit to the mounting
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 three power cables to the serverboard (ATX PWR,
PWR2 and PWR3 connectors). Finish by replacing the chassis left cover and
then restoring power to the system.
