2. Attach the other end of the FC cable to a switch or host bus adapter (HBA).
2.12.3 Connecting a SAS cable
NOTE
To connect the SAS cable to the tape drive:
1. Plug the HBA end of the SAS cable into the connector on the HBA.

If you have a SAS fan‐out cable, the end of the cable with only one connector, should be plugged
into the connector on the HBA.

If you are using a cable with a single connector on each end, plug the other end into the
connector on the tape drive.

If you are using a SAS fan‐out cable, plug one mini‐SAS connector into the connector on each
tape drive. The unused ends of the SAS fan‐out cable are single channel and not suitable for use
with disk arrays. Use the other ends to connect tape drives, or coil and secure them to the rack
to minimize stress on the connectors.
2.12.4 Connecting an Ethernet cable and a USB device
To connect the Ethernet cable to the library:
The connection to the Ethernet network is via an industry standard RJ45 copper interface on the rear
panel of the library. The Ethernet connection is used to access the library RMU over a network.
To connect the library to the Ethernet network, insert the Ethernet cable into the Ethernet port of the
library. When the plug is in the correct position, a click should be heard.
To connect the USB device to the library:
The USB port is on the rear of the library. It can be used for firmware upgrades/skin file updates
initiated via the operator control panel (OCP).

Figure 18 Connect the FC cable
Use only cables specified for your LTO SAS tape drive.
Each SAS tape drive has a mini‐SAS connector.
 Mini‐SAS connectors are keyed.
 Do not force a SAS cable's mini‐SAS connector into the tape
drive mini‐SAS connector because it might be keyed differently.
SAS signal rates require clean connections and a minimum number
of connections between the HBA and the library.
 Do not use adapters or converters between the HBA and the
library.
 A maximum SAS cable length of six meters is recommended.
