5.2.4 Replacing the Controller Module
Step 1. Remove the failed controller module. (See Section 5.2.3 above)
Step 2. Install a DIMM module on the new controller module. (See Section
5.5)
Step 3. Insert the replacement controller. Align the controller module with
the module bay at the rear of the subsystem. Gently slide the
controller module in.
Step 5. Fasten the hand screws. Once the controller module has been
completely inserted into the subsystem chassis, secure the controller
module to the chassis by tightening the hand screws at the sides of the
controller rear panel.
Step 6. Connect the controller module cables: Reconnect all of the cables
that were previously disconnected from the controller module. These
may include SCSI cables for host and expansion connections, an RS-
232C (audio jack) cable for serial port connection, and an Ethernet
cable for network connection.
Step 7. Power on: Once the new controller module has been properly
installed and the cables have been correctly connected, turn the
subsystem power on.
