3. If you have a Slave Disk Recorder board installed, remove both the SCSI B
cable (
Ë in Figure 3) and the ribbon cable (Ì in Figure 3).
4. If required, disconnect any other cables which pass over the top of the Master
Disk Recorder board. Be sure to make a cable diagram before you remove
the cables so that you can reinstall them later.
5. Use the Torx tool with the T15 tip to remove the screws which secure the
Master Disk Recorder board to the rear panel (see
Ê and Ë in Figure 4 as an
example).
6. Use the extraction lever on the front of the board and the extraction ring at
the back of the board to lift the circuit board free of the connectors on the
motherboard.
NOTE: If you have difficulty removing a circuit board, it may be necessary to
remove the screw mounting an adjacent circuit board or empty board slot
cover.
