Internal LTO-1 FC Drive Mounting Dimensions

Connecting a Fibre Channel Cable

The internal LTO-1 FC drive has two FC connectors that can connect to either a hub or a switch. In
systems that support failover, both FC connectors can be used to allow hosts to maintain a connec-
tion with the drive if one connection fails. The internal LTO-1 FC drive is 100-M5-SN-I compliant and
uses LC style connectors. Either 50 or 62.5µm multimode optical fiber cables can be used.

1.

Turn off all power to the drive and the computer.

2.

Attach the interface cable to either of the two LC optical interface connectors on the back of
the drive (labeled A and B in Figure 11 on page 26).

3.

In systems that support “failover,” connect the other port through separate loops or fabrics to
the same set of host computers. This way, if one connection fails, the other can be used to con-
tinue the data transfer.
