This tip is not option specific.

Solution

This is working as designed.

Workaround

The system can start successfully when the side cover has been removed if the two (2) pins on the system board for the "Side cover/Power Cut Off" switch are jumpered.

There is a cable connected to these pins, which connects to the intruder detection switch on the inside of the chassis.

In order to jumper the pins, the cable must be removed. These pins are on the system board close to the Universal Serial Bus (USB) Hypervisor slot.

Consult the PDSG or inside of side cover for the specific location on the system board.

Additional information

The system board has a cable connected to the 'Side Cover/Power Cut Off' switch pins. This automatically will send a shut down signal to the system if the side cover is removed during normal operation.

Jumpering these two (2) pins prevents this, and allows the system to start normally.
