3X-KZPEA Release Notes, June 2006

Note: Included in the 3X-H8411-AA adapter kit are two HD68 SCSI black connector plugs (P/N: 12-

10015-01) that MUST be installed on the internal SCSI connector of the KZPEA option for proper

shared bus operation. If only one of the two channels is to be used in a shared bus configuration

make sure that the connector plug is attached to the correct internal SCSI connector associated

with that bus for each KZPEA adapter.

Note: The DS15 system external SCSI port utilizes a different Tri-link (3X-H8411-BA kit w/one

12-44100-04 Tri-link)

SCSI Cabling Considerations for Shared Bus Support with Configuration B

The maximum LVD bus length for KZPEA shared SCSI bus support is 12 meters (39 feet). This includes

the combined length of the two SCSI cables (signal cable to the storage shelf and terminator cable between

nodes) as well as KZPEA and shelf internal bus lengths. The following cables are supported in the shared

bus configuration:

Signal cables between the mid-node and the storage shelf:

2-5-2 P/N

6-3 P/N Cable P/N Description

3X-BC56J-02 341174-B21 313374-001 6 foot VHDCI-to-VHDCI

3X-BC56J-03 341175-B21 313374-002 12 foot VHDCI-to-VHDCI

3X-BC56J-04 164604-B21 313374-004 24 foot VHDCI-to-VHDCI

Terminator cables between the system mid-node and the system end-node:

2-5-2 P/N

Description

3X-BN56A-03 3M TERM SCSI CABLE

3X-BN56A-04 4M TERM SCSI CABLE

The maximum allowable SCSI bus length for this configuration is achieved by using a 4M terminator cable

3X-BN56A-04 and a 24 foot 313374-004 cable.

Figure 2 is an example of a Config B supported KZPEA shared SCSI bus configuration.
