Connecting External Scsi Peripherals - HP A6829A User's Manual And Service Manual

Connecting External SCSI Peripherals

The A6829A adapter is capable of communicating with Low Voltage
Differential (LVD) or Single Ended (SE) SCSI devices. LVD allows up to
12m cable lengths with multiple SCSI devices, or 25m point-to-point
connections.
IMPORTANT As stated earlier in this chapter, do not mix LVD SCSI devices with SE
SCSI devices on the bus. If you do so, the entire SCSI bus will change to
SE. This will limit the bus performance to Ultra SCSI (40 MB/s).
Make all external SCSI bus connections to the A6829A adapter with
shielded, 68-pin LVD cables. The connectors on the cable are always
keyed to ensure proper mating.
NOTE No cables or external terminators are shipped with the A6829A adapter.
Cables usually are shipped with the external SCSI devices, and you can
get external terminators for the A6829A by ordering SCSI LVD/SE
terminator (HP product number C2370A).
