Resilient Links
This page shows the resilient links that have been set up for the stack,
as shown in Figure 7-14
.
This page is only available if there is a PS Hub 50 in the stack.
Only 10BASE-T and fiber optic ports (if there are fiber optic transceiver
modules fitted to hubs in the stack) can be part of a resilient link.
However, you can have Fast Ethernet Resilience in your stack with
multiple PS Hub 50 units. For more information, refer to “Fast Ethernet
Resilience” on
page 2-5
