Power Supply
The 2021M-T2R+/2021M-82R+ has a 700 watt redundant power supply consisting
of two power modules. Each power supply module has an auto-switching capabil-
ity, which enables it to automatically sense and operate at a 100V - 240V input
voltage.
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 (see contact information in the
Preface). The power supply modules have a hot-swap capability, meaning you can
replace the failed module without powering down the system.
Removing/Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap module. Replace with the same model (see part number in the
Appendix), which can be ordered directly from Supermicro.
1. Removing the power supply
First unplug the power cord from the failed power supply module. Then depress
the locking tab on the power supply module and use the handle to pull it straight
out with the rounded handle.
2. Installing a new power supply
Replace the failed hot-swap module with another identical power supply. Simply
push the new power supply module into the power bay until you hear a click. Secure
the locking tab on the unit and fi nish by plugging the AC power cord back into the
module.
