6-6 Power Supply
The 2027B-DE2R24L has a 920 watt redundant power supply consisting of two sep-
arate power modules. Each power supply module has an auto-switching capability,
which enables it to automatically sense and operate at a 100V - 240V input voltage.
When fully inserted into the chassis, the power supplies connect automatically to a
power distribution board (PDB). The PDB in turn connects to the midplane via two
black power connectors as shown in Figure 6-7.
Power Supply Failure
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. The PWR Fail
LED will illuminate and remain on until the failed unit has been replaced. Replace-
ment 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.
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.
Replacing the Power Supply
1. The SC927 chassis includes a redundant power supply (at least two power
modules), you can leave the server running if you remove only one power
supply at a time.
2. Unplug the power supply that you will replace.
3. Push the release tab (on the back of the power supply) as illustrated.
4. Pull the power supply out using the handle provided.
5. Replace the failed power module with the same model.
6. Push the new power supply module into the power bay until you hear a click.
7. Plug the AC power cord back into the module and power up the server.
