Air Shroud
The air shroud is used to concentrate airflow to maximize fan efficiency. The air shroud does
not require screws to set up.
Installing the Air Shroud
1. Begin by removing power from the system as described in section 3.1 and the chassis
cover as described in section 3.2.
2. Place air shroud in the chassis. The air shroud fits behind the two fans closest to the
power supply.
Power Supply
The AS -2013S-C0R has a redundant, hot-plug 740W power supply consisting of two 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.
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 Power Fail LED will illuminate and
remain on until the failed unit has been replaced. Replacement units can be ordered directly
from Supermicro. The hot-swap capability of the power supply modules allows you to replace
the failed module without having to power down the system.
Replacing the Power Supply
1. Check the LEDs on the power supplies to determine which module has failed.
2. Unplug the power cord from the failed module.
3. Push the release tab (on the back of the power supply) as illustrated, then pull the
power supply out using the handle provided.
4. Push the new power supply module into the power bay until you hear a click (replace
with the same model).
5. Reconnect the power cord to the new module.
