Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
Connecting in Multiple-Bus Failover Mode to
the Host
Use the following steps and Figure 2–3 to connect a pair of multiple-bus failover,
dual-redundant controllers to the host:
1. Configure both controllers. See “Configuring Dual-Redundant Controllers in
Multiple-Bus Failover Mode,” page 2–16.
2. Ensure the host and adapter are also configured. See the host user’s guide for
details.
3. Connect a trilink connector on host Port 1 or host Port 2 for one controller:
a. Connect the host bus cable onto one end of each trilink connector.
b. For a BA370 enclosure residing in an SW600 cabinet, snap the ferrite bead
on the bus cable within one inch of the controller.
4. Connect another trilink connector on host Port 1 or host Port 2 for a second
controller:
a. Connect the host bus cable onto one end of each trilink connector.
b. For a BA370 enclosure residing in an SW600 cabinet, snap the ferrite bead
on the bus cable within one inch of the controller.
5. Connect a terminator on the end of each trilink connector:
a. If the controller is at the end of the host bus, connect a terminator to the other
connector on the front of the trilink connector.
b. Otherwise, connect another host bus cable that continues to the next device
on the bus. Be sure to install a terminator at the end of the bus.
