12 m or less
This is the total permissible length of cable, including that internal to devices (when multiple changers are connected,
includes length of cable between changers).
SE SCSI bus:
3 m or less
This is the total permissible cable for each changer, including internal cables.

Permissible SE drives: Maximum 3
(for each changer)
* Due to limitations on cable length, SE drives should be installed in rear bays #1 to #3.
B. When not installing DRM-ULV16
(When LVD SCSI bus is separate from SE SCSI bus, or SE SCSI bus alone is used; see page 18, examples 4-6)
7
Connection Cable Length
(for each host adapter)
LVD SCSI bus:
12 m or less
This is the total permissible length of cable, including that internal to devices (when multiple changers are connected,
includes length of cable between changers).
SE SCSI bus:
6 m or less*
This is the total permissible length of cable, including that internal to devices (when multiple changers are connected,
