Single-Ended I/O Module
5–12 UltraSCSI RAID Enclosure
Cabling a Two-Enclosure Subsystem
Complete the procedures in Table 5–6 to connect the master enclosure
to one expansion enclosure. Perform this procedure for the I/O
modules on each SCSI bus, starting with SCSI bus 1 in Figure 5–3.
Each SCSI bus requires one BN37A cable for a total of six cables.
Caution
Not all array controllers support an UltraSCSI RAID
subsystem with more than one enclosure. Refer to the array
controller documentation to ensure the controller supports
expanded configurations.
Overtightening the I/O module spring-loaded mounting
screws can damage the threads.
