Installing the RAID Array 450 Cache Module, Controller, and ECB
1.6.1 Installing the Cache Module
Use the following procedure to install the write-back cache module:
1. Slide the write-back cache module into the appropriate slot in the shelf.
2. Use a gentle up-and-down rocking motion to help seat the module into the
backplane. Press firmly on the module until it is seated. Finally, press firmly once
more to make sure the module is seated.
3. Tighten the two screws on the front panel using a flat blade screwdriver.
1.6.2
Installing the Controller Module
1. To install the controller module, slide the module into the shelf.
2. Use a gentle up-and-down rocking motion to help seat the module into the
backplane. Press firmly on the module until it is seated. Finally, press firmly once
more to make sure the module is seated.
3. Tighten the two screws on the front panel using the flat blade screwdriver.
4. Reconnect the trilink connector and host cables.

Connecting the Controller and Cache Module
Use this procedure to connect the controller and cache module in a single controller
configuration. For a dual-redundant controller configuration, repeat steps 1.6.1 and 1.6.2
and then continue below.
To setup your subsystem for single controller operation, as shown in Figure 1
−
4, follow
these steps:
1. Attach one trilink connector to each controller port.
2. For a single subsystem configuration, attach a terminator to one port of the trilink
connector and the host SCSI cable to the other port.
For a multiple subsystem configuration, jumper the two trilink connectors together
with a short bus cable. On the remaining port of either trilink connector, attach a
terminator. Finally, attach the SCSI bus cable to the last available port.
