Details about FC I/O blades include:
• You must be running 400-level code or above in order to use FC I/O
blades.
• Each expansion module can support up to two FC I/O blades.
• A maximum of four FC I/O blades can be present in any library
configuration.
• A maximum of four FC drives can be connected to one FC I/O blade.
• FC I/O blades cannot be installed in control modules. However, FC
tape drives in the control module can be connected to FC I/O blades
in an expansion module.
• Each FC I/O blade is accompanied by a fan blade that cools the FC
I/O blade. The fan blade is installed to the right of the I/O blade in
the expansion module. Each expansion module has four bays and can
accommodate two FC I/O blades and two fan blades.
Figure 31
shows the FC I/O blade and I/O blade fan installed in the expansion
module. For instructions on installing the I/O blade fan, see
Adding,
Removing, and Replacing the I/O Fan Blade
on page 317.
• The recommended order of installing the FC I/O blade and fan blade
in any expansion module is starting from the bottom two bays and
moving up.
Caution:
If you are adding a new FC I/O blade or completely
removing an FC I/O blade, be sure to read
Working With
Control Paths
on page 78. If you do not configure control
paths correctly, you will experience communication
problems with tape drives, partitions, and the medium
changer (robot).
