Remove the Old Regulator Board from the Card Carrier
Step 1. Disconnect, tag, and lockout power to the drive.
Step 2. Remove the OIM cover by loosening the two (2) cover retaining screws (refer to figure 1). Set the
cover aside.
Step 3. Disconnect cable connector J9 from the lower left side of the Regulator board (refer to figure 2).
Step 4. Remove the four (4) screws which secure the OIM assembly to the card carrier. Disconnect the OIM
ground wire. Set the OIM assembly aside.
Step 5. Note the wire lead connections to the Regulator board terminal strip. If these connections are not
documented elsewhere, record them now. Then disconnect these wire leads from the Regulator board
terminal strip.
Step 6. Disconnect ribbon cables J5, J6, and J7 from the Regulator board (refer to figure 3). Also remove
cable J25.

located at the bottom corners of the board; one is located at the center of the board. If the drive is in
an upright position, be careful not to let the Regulator board slip out of the card carrier when the last
screw is removed.
Set the screws aside for later use. Then slide the old Regulator board out of the card carrier.
