______________________ Note _______________________

If you connect a trilink connector to a SCSI bus adapter, you may block access to an adjacent PCI slot. If this occurs, use a Y cable instead of the trilink connector. This is the case with the KZPBA-CB and KZPSA-BB SCSI adapters on some AlphaServer systems.

Use the H879-AA terminator to terminate one leg of a BN21W-0B Y cable or H885-AA trilink.

Use an H8861-AA VHDCI trilink connector (see Figure 3–1) with a DS-BA35X-DA personality module to daisy chain two UltraSCSI BA356s or to terminate external to the UltraSCSI BA356 storage shelf. Use the H8863-AA VHDCI terminator with the H8861-AA trilink connector.
