Important: SAS signal rates require clean connections between the HBA and tape drive. Do not use
adapters or converters between the HBA and the tape drive. For reliable operation, use a SAS cable length
of maximum 6 meters for 6 Gbps or slower SAS speed. For 12 Gbps SAS speed, use a SAS cable length of
maximum 3 meters.
Connecting USB cables
Two USB ports are on the library, one in the front and one in the rear. USB connections are used by service
personnel for diagnostic and service procedures. Attach one end of the USB cable to your notebook or
other device and the other end to the front or rear USB port of the library.
Important: USB cable lengths of more than 3 meters are NOT supported for the front or rear USB ports.
Connecting Ethernet cables
To use the Management GUI, connect an Ethernet cable from the bottom Ethernet port on the Base
Module controller to your network. See "Rear panel" on page 6 for the location of the Ethernet ports.
Remember: Ethernet port A (bottom Ethernet port) is the primary port. The second Ethernet port, Port B,
is for redundancy.
