2.9 SCSI Terminators and Trilink Connectors

Table 2–4 describes the supported trilink connectors and SCSI terminators and the context in which you would use them.

Table 2–4: Supported SCSI Terminators and Trilink Connectors

Trilink	Den-	Pins	Configuration Use
Connector or	sity
Terminator
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	Low	50-pin	Terminates a TZ885 or TZ887 tape drive.
H8860-AA
341102-001	High	50-pin	Terminates a Compaq 20/40 GB DLT Tape Drive
H879-AA or	High	68-pin	Terminates an H885-AA trilink connector,
330563-001			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.
