SCSI Cable Length
The maximum allowable cable length for an LVD SCSI bus, including all internal and external cables, is
specified as follows:
•
If you have more than two devices on the LVD bus, the maximum allowable length is 12
meters (39 feet).
•
If you are making a point-to-point connection (target and initiator only), the maximum length
is 25.0 meters (82 feet).
To determine the cable length of the bus, measure the lengths of all external SCSI cables. Add those
lengths together. To that sum, add 20 centimeters (8 inches) for the internal cable length used by the tape
drive and 5 centimeters (2 inches) for the internal cable length used by the robot.
SCSI Terminator
Plasmon recommends using an AMP 796051-1 (SE/LVD Multi-mode) SCSI terminator. Termination must
be external; do not use internal terminators.
Ethernet Cable Requirements
As an option, the library may include an Ethernet port on the back panel. The Ethernet port connector is an
RJ-45 shielded connector. To connect to the Ethernet port, use an approved Category 3 (10BaseT
connection) or Category 5 (100BaseT connection) data-grade cable compliant with EIA/TIA 568.
NOTE
To comply with the regulations and standards listed at the front of this
manual, all Ethernet cables you use with the library must be properly
shielded.
The figure below shows the Ethernet port’s pin locations.
