RAID Array 410 to 450 Upgrade

1–12

EK–SM410–UP. A01

1.5.3  Controller Module Removal

Use the following procedure to remove the controller module. Repeat the procedure for
dual-redundant controller configurations.

1.  Access the controller modules in the cabinet.

2.  Unsnap and remove the ESD shield covering the program card by pulling out on the

two retainer buttons.

3.  Remove the program card by pushing the eject button on the controller panel. Pull

the card out and save it.

Figure 1–2  RAID Array 410 Controller Panel

4. With a small blade screwdriver, loosen the captive screws on the trilink connector

(see Figure 1-3) and remove the trilink from the front of the controller. Do not
remove cables or terminators from the trilink or you will interrupt the host SCSI bus.
You will have to work around any SCSI cable or terminator connections when
removing the trilink.
