Redundant Links
 
The BayStack 10BASE-FL RDN Media Adapter supports 
redundant links between Bay Networks BayStack Ethernet hubs, 
System 5000 hubs, and other Bay Networks hubs that support 
redundant links. If one fiber connection in a redundant pair 
breaks, the standby link automatically takes over in less than 10 
microseconds. This redundant link feature allows you to build 
Ethernet dual-homing and mesh-type topologies. The port at both 
ends of the fiber connection must support Bay Networks remote 
signaling.
A jumper is used to set the redundant 10BASE-FL media adapter 
port to operate in redundant mode with a 10BASE-FL fiber port 
on another hub.
