5.Remove an existing PSU or FOM

Disconnect the power cord before removing the PSU.

The PSU and switch may overheat or be damaged by dust and debris if bays are left uncovered.

Loosen the two Phillips screws on the PSU or FOM until the screws disengage from the switch chassis (see Figure 1).

Slowly and carefully slide the PSU or FOM out of the switch’s power supply bay.

If you remove a PSU, or FOM, from the switch replace the PSU, or FOM, to prevent dust and debris from entering the switch chassis and to maintain proper airflow.

6.Insert a PSU

Slowly and carefully slide the PSU into the switch’s power supply bay.

Firmly press the PSU home (until its front panel engages or nearly engages the switch chassis).

7.Secure the PSU

Keep the PSU in a straight alignment and insert it slowly. Forcing a misaligned

PSU is likely to damage the chassis and PSU.

Tighten the two Phillips screws on the PSU’s faceplate (see Figure 1 on page -5).
