Compaq StorageWorks UltraSCSI RAID Enclosure (DS-BA370 Series) User's Guide (EK-BA370-UG. C02, September 1998)

Single-Ended I/O Module
5–8 UltraSCSI RAID Enclosure
Caution
The Compaq UltraSCSI controller does not support
connecting or disconnecting a SCSI bus cable when both
data and power are present on the connector—a “
hot
swap
.” Only connect or disconnect SCSI bus cables using
the “
cold swap
” method.
Table 5–2 UltraSCSI Bus Expansion Rules
1. The I/O module numbers (1 through 6) correspond to the enclosure
SCSI bus numbers.
2. Always connect cables between enclosures to the same I/O module
number. That is, connect I/O module 1 on the master enclosure to I/O
module 1 on an expansion enclosure.
3. The
first cable
on any I/O module always connects to the
left
connector
.
Note
Connecting a cable to the
right
I/O module connector removes
the external SCSI bus termination from the module.
4. The
second cable
on any I/O module always connects to the
right
connector
.
