Power Supply
The SSG-6049P-E1CR24H/L has a 1200 watt redundant, hot-plug power supply consisting
of two power modules. The power modules are hot-swappable.
The power supplies are auto-switching capable, allowing them to automatically sense and
operate at a 100v to 240v input voltage. If either of the two power supply modules fail, the
other will take the full load and allow the system to continue operation without interruption.
The Power Fail LED will illuminate and remain on until the failed module has been replaced.
Replacements can be ordered directly from Supermicro.
Replacing a Power Supply Module
1. Determine which power supply module needs to be replaced and unplug the power cord
to that module.
2. Push the release tab (on the back of the power supply) as illustrated, to release the
power module from the chassis.
3. While holding down the release tab, pull the power supply out using the handle provided
on the power module.
4. Replace the failed power module with the same model power supply.
5. Push the new power supply module into the power bay until the tab clicks into the
locked position.
6. Plug the AC power cord back into the module and the replacement power module will
automatically power-up.
