Configuration Use
H885-AA Three 68-pin Trilink connector that attaches to high-density,
68-pin cables or devices, such as a KZPSA-BB,
KZPBA-CB, HSZ40, HSZ50, or the differential
side of a SCSI signal converter. Can be
terminated with an H879-AA terminator to
provide external termination.
H8574-A or
H8860-AA
Low 50-pin Terminates a TZ885 or TZ887 tape drive.
341102-001
High 50-pin Terminates a Compaq 20/40 GB DLT Tape Drive
H879-AA or
330563-001
High 68-pin Terminates an H885-AA trilink connector,
BN21W-0B Y cable, or an ESL9326D
Enterprise Library tape drive.
H8861-AA VHDCI 68-pin VHDCI trilink connector that attaches to VHDCI
68-pin cables, UltraSCSI BA356 JA1, and HSZ70
or HSZ80 RAID controllers. Can be terminated
with an H8863-AA terminator if necessary.
H8863-AA VHDCI 68-pin Terminate a VHDCI trilink connector.
152732-001
VHDCI 68-pin Low Voltage Differential terminator
The requirements for trilink connectors are as follows:
• If you connect a SCSI cable to a trilink connector, do not block access to
the screws that mount the trilink, or you will be unable to disconnect the
trilink from the device without disconnecting the cable.
• Do not install an H885-AA trilink if installing it will block an adjacent
peripheral component interconnect (PCI) port. Use a BN21W-0B Y cable
instead.
