7.6.2 Accessing the OIM and Disconnecting It from the Regulator Board
These steps are required for both

replacement.
Important:
Unless otherwise indicated, keep all hardware for the replacement
procedure.
Step 1. Loosen the screws that secure the front cover to the drive.
Step 2. Remove the front cover.
Step 3. Disconnect the communication cable from J9 on the Regulator board by
pressing down the locking clip and pulling the cable out.
Step 4. Remove the four screws holding the
OIM

Step 5. Pull the

mounting plate. Slide the ground
wire off its connection.
Important:
Ground wires on older versions of the
OIM
are fastened by a nut. If you are
replacing an older version, keep the hardware so you can re-attach the
