Introduction
Networks deliver critical services to users.
If a network link fails, those services become unavailable, and users cannot do their
jobs. A network link can fail due to reasons such as:
 Module failure
 Cable severed or damaged
 Switch or power failure
To protect the network from these types of failures, you can install redundant links.
For example, on the network shown here, you could install one or more redundant
links to ensure data could be transmitted across the network if the highlighted link
failed. This illustration shows two possible redundant links, and you can see how
each one allows Workstation A to communicate with Server B.
