Technical data

______________________ Note _______________________
Each internal cable is up to 2.5 meters (8.2 feet) long. The length
of the internal cables, two per SCSI bus, must be taken into
consideration when ordering SCSI bus cables.
The maximum length of a differential SCSI bus segment is 25
meters (82 feet), and the internal tape drive SCSI bus length is 5
meters (16.4 feet). Therefore, you must limit the external SCSI
bus cables to 20 meters (65.6 feet) maximum.
8.13.3.4 Connecting the ESL9326D Enterprise Library to the Shared SCSI Bus
The ESL9326D Enterprise Library has 5 meters (16.4 feet) of internal SCSI
bus cabling for each pair of tape drives. Because of the internal SCSI bus
lengths, you cannot use a trilink connector or Y cable to terminate the SCSI
bus external to the tape library as is done with other devices on the shared
SCSI bus. You must terminate each SCSI bus at the end of the SCSI bus by
installing a terminator on the SCSI bulkhead SCSI connector. Therefore,
you must ensure that the ESL9326D Enterprise Library is on the end of the
shared SCSI bus in TruCluster Server configurations.
______________________ Note _______________________
We recommend that you put disk storage devices on separate
shared SCSI buses.
Use 328215-001 (5-meter; 16.4 foot), 328215-002 (10-meter; 32.8-foot),
328215-003 (15-meter; 49.2-foot), 328215-004 (20-meter; 65.6-foot), or
BN21K (BN21L) cables of the appropriate length to connect the ESL9326D
Enterprise Library to a shared SCSI bus. The entire shared SCSI
bus, including ESL9326 internal cables, cannot exceed 25 meters (82
feet). Terminate each SCSI bus with a 330563-001 (or H879-AA) HD-68
terminator. Connect the cables and terminator on the SCSI bulkhead SCSI
connectors as indicated in Table 8–21 to form shared SCSI buses.
