Single-Ended I/O Module
5–16 UltraSCSI RAID Enclosure
Cabling a Three-Enclosure Subsystem
Complete the procedures in Table 5–8 to connect the master enclosure
to two expansion enclosures. The second expansion enclosure
connects to either the master enclosure or the first expansion
enclosure. Table 5–8 connects the second expansion enclosure to the
first expansion enclosure. Perform this procedure for the I/O modules
on each SCSI bus, starting with SCSI bus 1 (identified in Figure 5–3).
Each SCSI bus requires two BN37A cables for a total of 12 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.
Note
The procedure in Table 5–8 connects a second expansion
enclosure to the first expansion enclosure. To connect the
second expansion enclosure to the master enclosure, do the
following:
• Substitute the first expansion enclosure for the master
enclosure in steps 5 through 7.
• Substitue the master enclosure for the first expansion
enclosure in steps 8 through 12.
