Disk drive cable replacement

The Messaging Application Server (MAS) or a supplementary tracing server has one IDE drive and a DVD player. The ribbon cable for these drives can be replaced.

Replacing the IDE drive and DVD cable

To replace the IDE/DVD drive ribbon cable:

1. Verify that the replacement equipment is on site and appears to be in usable condition, with no obvious shipping damage.
2. Verify that the replacement cable has three IDE connectors (one for the motherboard, one for the IDE drive, and one for the DVD).
3. Shut down the server and unplug the AC power cords.
4. Remove the front bezel and top cover.
5. Remove the circuit card hold-down bracket.
6. Remove the IDE/DVD drive cable as follows. See figure Replacing an IDE ribbon cable.
   1. Disconnect the IDE ribbon cable from the DVD and the IDE drive.
   2. Release the tie-down strap that holds the ribbon cable to the chassis.
   3. Disconnect the other end of the ribbon cable from the primary (PRI IDE) connector on the motherboard.
   4. Remove the cable. Set it aside.
7. Install the new cable by reversing the removal steps (see Step 6).

Caution! Fold the new cable carefully so it fits neatly into the chassis, but is not stressed.

8. Replace the circuit card hold-down bracket.
9. Replace the top cover and front bezel.
10. Restore power to the server.

If the server boots correctly, the new cable should be working.
