Assembling an UltraSCSI RAID Subsystem
B–2 UltraSCSI RAID Enclosure
Installation Sequence
The basic installation sequence is the same for all UltraSCSI RAID
subsystems, whether they use one, two, or three DS–BA370
enclosures. To reduce the possibility of multiple interacting problems,
the preferred assembly sequence is as follows:
1. Assemble and test the master enclosure.
Note
Prior to power application and testing, a minimum
compliment of power components require installation, such
as the standard (n+1) configuration (see Chapter 6).
2. Assemble the first expansion enclosure.
3. Connect the first expansion enclosure to the master enclosure and
test the subsystem operation.
4. Assemble the second expansion enclosure.
5. Connect the second expansion enclosure to either the master
enclosure or the first expansion enclosure and test the subsystem
operation.
The assembly procedures for an enclosure are almost identical to
those described elsewhere in this publication. Therefore, rather than
repeating the procedures, the following sections primarily address
special assembly considerations. The recommended sequence for
assembling an UltraSCSI RAID enclosure is as follows:
WARNING!
A full enclosure weighs more than 102 kg (225 lb). To
prevent personal injury:
• Always mount an empty enclosure into a cabinet
prior to installing devices.
• Use at least two people to lift, align, and insert the
enclosure into a cabinet.
