6-5 Power Supply
The SuperServer 1028R-MCT has a single 600 watt power supply while the 1028R-
MCTR features redundant, 600W hot-plug high-efficiency power supplies. Both are
auto-switching capable, enabling the power modules to automatically sense and
operate with a 100V to 240V input voltage.
Power Supply Failure
1028R-MCT
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 chassis,
power must be completely removed from the server before removing and replacing
the power supply unit for whatever reason.
Removing/Replacing the Power Supply (Figure 6-6)
1. First power down the system and unplug the AC power cord from the power
supply.
2. Extend the chassis from the rack if necessary, then remove the top chassis
cover.
3. To remove the failed power unit, remove the two screws that secure the
power module to its housing inside the chassis. You can then pull the unit
straight out of the chassis.
4. Replace the failed unit with another unit of the same wattage. You must re-
place it with the exact same power supply (same model number).
5. Carefully insert the new unit into position into the chassis and secure it with
the two screws you removed previously.
6. Reconnect the AC power cord, replace the top chassis cover and push the
unit back into the rack.
7. Finish by powering up the server with the power button on the front control
panel.
1028R-MCTR
An amber light will be illuminated on the power supply when the power is off. An
illuminated green light indicates that the power supply is operating. If either of the
two power supply modules fail, the other module will take the full load and allow
the system to continue operation without interruption. A power fail condition will be
displayed on the front control panel until the failed unit has been replaced.
Replacement units can be ordered directly from Supermicro. The power supply
units have a hot-swap capability, meaning you can replace the failed unit without
powering down the system.
Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply unit. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the same model (see part number in the Ap-
pendix), which can be ordered directly from Supermicro.
Removing the Power Supply
1. First unplug the AC power cord from the failed power supply module.
2. Depress the release tab on the power supply module.
3. Use the handle to pull it straight out with the rounded handle.
Installing a New Power Supply
1. Replace the failed hot-swap unit with another identical power supply unit.
2. Push the new power supply unit into the power bay until you hear a click.
3. Finish by plugging the AC power cord back into the new module.
