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 9U Library Expansion Module. FC I/O blades and fan blades
are hot-swappable.
FC I/O blades cannot be installed in the 5U Library Control Module, so
your library configuration must include at least one 9U Library
Expansion Module to include FC I/O blades. Each 9U Library Expansion
Module can house up to two FC I/O blades. Depending on the number of
installed 9U Library 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 5U Library Control Module, can be connected to an FC I/O blade in a
9U Library 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 on
page 396.
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.
