ERVER 6015B-Ni Manual

Power Supply
The SuperServer 6015B-Ni has a single 520 watt power supply, which is auto-
switching capable. This enables it to automatically sense and operate with a 100V
to 240V input voltage. A power on/off switch is included on the back of the unit.
This switch should be turned to the off position before removing the power cord
when replacing the unit.
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 information in the Preface). As there is only one power supply unit
in the 6015B-Ni, the server must be powered down before removing and replacing
the power supply unit for whatever reason.
Removing/Replacing the Power Supply
1. Removing the power supply
First turn the power switch on the control panel and the switch on the power sup-
ply off, then unplug the power cord from the system and all peripheral devices.
Remove the chassis cover by pressing the two release buttons on the top of the
chassis (near the front) and push the chassis top rearward about one inch before
lifting it completely off. To remove the failed power unit, unplug the power cables
from the connections on the serverboard. Then unscrew the bracket securing the
power supply to the chassis and lift it out. See Figure 6-5.
2. Installing a new power supply
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 (Supermicro part number PWS-521-1H20). Carefully insert the new
unit into position and screw it into the chassis. Plug the power cables back into
their connectors on the serverboard. Replace the chassis top cover and reposition
the unit back into the rack. Reconnect the power cord and turn the switch on the
back of the power supply to the on position. Finish by depressing the power button
on the chassis front control panel.
