Connecting Ultra Scsi Bus Cables And Host Cabling; Ultra Scsi Bus Cables; Figure C-2. I/O Module Mounting Locations - Compaq StorageWorks 2100 User Manual

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
controllers, which support all six I/O modules. For Model 2100 enclosures, a blank panel covers
the four vacant I/O module bays.
