What to Do

  1. Disconnect the LED/keyswitch assembly cables from the UltraSCSI backplane:

    1. Disconnect the keyswitch cable from connector J0601.

      This connector is located at the upper-left corner of the backplane (as viewed from the rear).

    2. Disconnect the LED ribbon cable from connector J0602 at the front of the UltraSCSI backplane.

      This connector is located in the upper-left corner of the backplane (as viewed from the front). Lift the thin collar at the top of the connector to disconnect the cable. Take note of how the cable is routed.

  2. Detach the LED ribbon cable from the underside of the removable media shelf.

    Note -

    At the front-left corner of the system, the LED ribbon cable is secured to the underside of the removable media shelf with double-sided adhesive tape. Carefully pull the cable downward to detach it from the shelf. Reach in through the side of the chassis or open the disk access door for better access to the cable.
