7.3 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.
Tip: For more information about EHX, see your EHX documentation (including EHX Help).
7.4 Simplex fiber cabling
7.4.1 Single card set redundancy
In this scenario, each matrix contains one fiber-optic Linking card set
(see
Figure 25: Ring topology: single card set redundancy ).
This approach still affords fiber connection redundancy since each rear card houses two
fiber-optic transceivers.
Note:
In the absence of an Uninterrupted Power Supply (UPS), this configuration will not protect
against loss of the node or the matrix itself.
