3. Unplug the power cord.

4. Loosen and remove the retaining screw on the left side of the power supply.

5. Pull the power supply out of the VessRAID enclosure.

Installing the new power supply

To install the power supply:

1. Carefully slide the power supply into the enclosure.

2. Install and tighten the retaining screw on the left side of the power supply.

3. Plug in the power cord.

4. Switch on the power supply.

5. Verify that the new power supply LED is green.

This completes the power supply replacement procedure.

Replacing an I/O Module

The I/O module monitors and manages the logical drives. When the I/O module

is replaced, all of your logical drive data and configurations remain intact because

this logical drive information is stored on the disk drives.

I/O module failure is rare. But you might have to remove and reinstall the same

I/O module in order to replace a cooling fan as described in this chapter.

Removing the old I/O module

To replace the I/O module:

1. Shut down the VessJBOD. Turn OFF the power supply switch (switches).

2. Disconnect the SAS, serial, and power cables.

3. On the I/O module, loosen the thumbscrew, swing the latch to the right and

pull the I/O module out of the enclosure. See Figure 1.

Caution

• Do not replace the I/O module based on LED colors alone.

Only replace the I/O module when directed to do so by

Promise Technical Support. See page 44.

• Only a qualified technician should perform this procedure.

• You must shut down the VessJBOD subsystem before you

can perform this procedure.
