Midplane

The midplane is a passive component that provides a reliable hot-swap interconnect
between the active components of the system. See Figure 6-7 below for a list of
connections to the midplane.

Power Supply

The 6038R-DE2CR16L has a 1200 watt redundant power supply consisting of
two separate 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.

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 SC937 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.
