DECrepeater 90FS Installation and Configuration
Redundant Fiber-Optic Link Configuration (Cont.)
A link failure can be caused by any of the following occurrences:
•
Loss of carrier (light in a fiber-optic device)
•
Auto-partitioning of the port
Simple Redundant Link Configuration
The DECrepeater firmware allows the configuration of a redundant fiber-optic
Ethernet link from multiple ports. In its simplest form, a redundant link consists of a
pair of master ports that reside on one module, each connected to independent ports
on a remote module (see illustration). These remote ports may be responder ports or
non-responder ports.

Configuration Example
Once these ports are properly configured using HUBwatch and connected together,
one connection is the active link and the other is the standby link.
