Troubleshooting from the remote I/O optical adapter LEDs
When creating the remote I/O optical adapter connection configuration depicted in Figure 13-24, identify the
location of the failure by using the combination of LED status for the remote I/O optical adapter.

The location of the failure cannot be determined from the LEDs.
Return to the troubleshooting flow in Figure 13-21, and investigate
the failure according to the instructions in Nos. 2 through 15.
An error might be present in the remote I/O cable.
Check the connection of the remote I/O cable and the termination
resistor.
There might be a problem with the power of the unit in which the
RI/O optical ADP (a) is installed. Check the power status.
An error might be present in the RI/O-IF module.
Investigate the RI/O-IF module.
