Connecting The Scsi Cable - HP 6000 SERIES Hardware Installation Manual

Hardware Installation Manual HP Series 6000
Connecting the SCSI Cable
One or more mass storage systems can be connected to the host computer.
Before connecting to the host computer, ensure that the cabling conforms with
the following SCSI cabling standards.
Caution
,
Your mass storage system is a single-ended SCSI device. Do not
mix differential-ended SCSI hosts with single-ended mass storage
systems. Connecting a differential host to a single-ended mass
storage system could damage both the host and the mass storage
system.
• The SCSI bus allows a maximum of eight devices, including the host computer
system. Since
I
your mass storage system can contain from one to five SCSI
devices, you must make sure you know the number of SCSI devices within
your mass storage system before connecting it to the system bus.
It
is possible
that two fully loaded mass storage systems could exceed the SCSI device limit.
• The total length of the SCSI cables must not exceed six meters. In addition to
external cables, each mass storage system contains 1.75 meters of internal
SCSI cabling. This dimension must be included in cable length calculations.
• The last mass storage system on the bus must have a SCSI terminator (part
number K2291) fitted on its unused SCSI connector.
1. Disconnect power to the host computer and the mass storage system.
2. Connect the host computer SCSI cable to either of the two SCSI connectors
on the rear panel of the mass storage system. Ensure that the connector
retaining clips are locked in place.
3. Connect the next SCSI device or the SCSI terminator to the other SCSI
connector on the mass storage system.
