Configuring a fiber optic connection

There are a number of ways that optical connections can be made between systems
depending on the level of redundancy required.
When a break occurs in the fiber ring, a solid red status light will be shown at the fiber card
downstream from the break and the link status LEDs may show amber. Other fiber cards will
intermittently show red, as the ring attempts to recover. If the system layout is displayed by
EHX the faulty links are shown in red.
In order to diagnose faults or switch between primary and secondary rings or between
primary and backup fiber linking cards the system monitoring screen in EHX must be
used.
Note: For more information about EHX, see your EHX documentation (including EHX Help).
