Each FC I/O blade has six auto-negotiating, 4 Gb/s FC ports and

backplane connections. The FC I/O blade provides two host

communication ports and four connection ports to FC drives. Each FC

I/O blade is cooled by a fan blade that is installed next to the FC I/O

blade in the expansion module. FC I/O blades and fan blades are hot-

swappable.

FC I/O blades cannot be installed in the control module, so your library

configuration must include at least one expansion module to include FC

I/O blades. Each expansion module can house up to two FC I/O blades.

Depending on the number of installed expansion modules, the library can

support from one to four FC I/O blades. No library configuration can

contain more than four FC I/O blades. Any FC drive in the library,

including drives in the control module, can be connected to an FC I/O

blade in an expansion module.

The FC I/O blade indicates its status with three LED status indicators.

These indicators are green, amber, and blue in color.

•

Green represents processor status.

•

Amber represents health status.

•

Blue represents power-control status.

Figure 9

shows the FC I/O Blade, including LEDs. For more information

on the behavior of the FC I/O Blade LEDs, see Blade Status LEDs

page 500.

For information on configuring I/O blades, see Working With FC I/O

Blades on page 109.

For information on installing and cabling FC I/O blades and FC tape

drives, see Chapter 12,

Installing, Removing, and Replacing.

Note: FC I/O menu commands are available for use only when FC

I/O blades are installed in the library.
