The I/O modules are functionally identical, but are not interchangeable. Module A can only be installed
at the right end of the enclosure, and module B can only be installed at the left end of the enclosure. See
Figure 10 .
Each I/O module has two ports that can both transmit and receive data for bidirectional operation.
Activating a port requires connecting a FC cable to the port. The port function depends upon the
loop. See Figure 12 .

I/O module status indicators
There are three status indicators on the I/O module. See Figure 11 . The status indicator states for
an operational I/O module are shown in Table 7 . Table 8 shows the status indicator states for a
non-operational I/O module.
