Figure 5 I/O module detail

Each I/O module has two ports that can transmit and receive data for bidirectional operation.

Activating a port requires connecting a Fibre Channel cable to the port. The port function depends

upon the loop.

I/O module status indicators

There are five status indicators on the I/O module. See Figure 5. The status indicator states for an

operational I/O module are shown in Table 2. Table 3 shows the status indicator states for a

non-operational I/O module.
