- Replace the top cover.
- Restart the system.
Replace a power supply unit
This server implements two 1100 W AC-DC switching power supplies. Each power supply can operate as a single supply or in an N+1 parallel operation with active load sharing in an N+1 redundant configuration.
If either of the two power supply modules fail, the other module takes the full load and allow the system to continue operation without interruption. However, the global failure indicator on the front panel remains lit until the failed module is replaced.
- AC (top LED)
- DC (middle LED)
- ! (bottom LED)
The following figure shows the LEDs.

The LEDs are driven by internal circuitry and illuminate in an N+1 configuration even without input power. See the following table for the power supply LED meanings.
| Power supply condition | Power supply LEDs |
|---|---|
| No AC power to all PSUs | Off |
| No AC power to this PSU | AC LED 1 Hz flashing green |
| AC present/only standby output on/ CR-State | AC LED green |
| Power supply DC output ON and OK | AC and DC LED green |
| Power supply failure | FAIL LED amber |
| Power supply warning | 1 Hz flashing amber |
Follow these steps to replace a failed power supply.
- Unplug the power cord.CAUTION:After you remove the power cord, wait for at least 15 seconds before you attempt to remove the power supply unit for maintenance or repair to avoid accidental shock or personal injury due to any residual power supply electrical charge.
- Actuate the green power supply lever to release the power supply.
- Slide the power supply out of the chassis, as shown in the following figure.
Figure 5. Removing the PSU 
- Insert the new power supply fully into the chassis until the green lever snaps into place.
- Insert the power cord.
- Verify that all power supply indicators are normal.
