Replace JBOD Control Board (I/O Module)

The JBOD control board is mounted on a tray near the rear of the chassis. It should only be accessed in the rare event that a defective board must be serviced. If a replacement is necessary, the entire rear node should be replaced.

Note: This procedure should only be performed by a qualified technician.

1. Power down the system as described in Power Down the X200.

2. Remove the power supply modules.

3. On each side handle of the motherboard sled, slide the lock forward to unlock it.

4. Simultaneously press the release tabs on both handles and turn the handles forward and down, then pull the motherboard sled out of the chassis.
