6-5 Power Supply
The SuperWorkstation 7045A-3 has a single 645 watt power supply. This power
unit is equipped with low-noise technology, making the system ideal for workstation
environments.
The power supply has an auto-switching capability that enable it to automatically
sense and operate with 100 or 240 volt inputs. The power module is PFC (Power
Factor Correction) compliant.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to replace
the unit. Replacement units can be ordered directly from Supermicro (see contact
information in the Preface). As there is only one power supply unit in the 7045A-3,
power must be completely removed from the server before removing and replacing
the power supply unit for whatever reason.
Replacing the Power Supply
1. Accessing the power supply
For safety reasons, you will need to remove power from the system when replac-
ing the power supply on the 7045A-3. The power supply 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. 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 of the same input voltage, output voltage
and wattage. It is highly recommended to replace it with exactly the same model
power supply (PWS-0060). Gently but fi rmly push the new unit all the way into the
open bay. Secure it to the chassis using the locking tab. Plug the power cord back
into the new power supply. Finish by depressing the power button on the chassis
front control panel.
