Preparing an Enclosure for Use
C–3
Follow the specific installation procedure for each element as required:
■
Install the EMU using Table 8–3.
■
Install all ECBs and blanks using Table 8–9. Cache A requires an ECB in bay A1 or
A2. Cache B requires an ECB in bay B1 or B2.
■
Install all three fans using Table 8–12.
Installing Array Controllers and Cache Modules
The enclosure accommodates either a single or dual array controller configuration. For
each array controller installed, a corresponding cache module and ECB must also be
installed.
Install all array controllers, cache modules, and blanks (if applicable) using Table 8–14.
Connecting Ultra SCSI Bus Cables and Host Cabling
Ultra SCSI bus cables connect the enclosure to as many as six storage enclosures. Host
cabling connects the enclosure to a host computer or host adapter.
Ultra SCSI Bus Cables
Bus cables connect to enclosure I/O modules (see Figure C–2). See Chapter 1, Table 1–3
for available cable lengths.

NOTE:
Model 2100 enclosures use HSG60 array controllers, which support only two I/O
modules—SCSI bus 1
1
and SCSI bus 2
2
; whereas Model 2200 enclosures use HSG80 array
controllers, which support all six I/O modules. For Model 2100 enclosures, a blank panel covers
the four vacant I/O module bays.
