Number Description
1 SAS port 0
2 SAS port 1
3 Drive sled indicators (see Drive sled back panels)
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.
Powering on the library
Steps to power on the library.
About this task
1. Plug the power cables into the power connectors on each module and into power outlets.

• The library has dual redundant power supplies. To increase redundancy, plug each power cord into a
different AC power circuit.
• A power supply is required in expansion modules if drives are installed.
2. Power on the library by pressing Power on the Base Module just below the Operator Panel and hold
for 5 seconds. See “Front panel” on page 5 for the location of the Power button. When the library is
powered on, it
