Replacing the Power Supplies
The F418BC2 chassis includes 2200 Watt power supplies. These power supplies are auto-
switching capable. This enables the power supplies to automatically sense and operate at a
100V to 240V input voltage. An amber light will be illuminated on the power supply when the
power is off. An illuminated green light indicates that the power supply is operating.
Power Supply Replacement
The F418BC2 chassis utilizes redundant, hot-plug power supplies.. In the unlikely event that
the power supply unit needs to be replaced, one power supply can be removed, without
powering down the system. Replacement units can be ordered directly from Supermicro.
Changing the Power Supply
1. Disconnect the AC power cord on the back of the failed power supply.
2. Press the release tab on the back of the power supply and pull the power supply out
using the handle provided.
3. Push the replacement power supply module into the power bay until it clicks into the
locked position.
4. Plug the AC power cord back into the module and power up the node.
