Repeater Redundancy

b.Specify up to 8 ports that will act as the redundant connections by using

the Module and Port boxes to indicate each port, and then clicking on to enter each port into the circuit.

c.By default, all ports are created as Inactive Backup ports. You should designate both a Primary port and an Active port. Typically, you would configure the same port to be both Primary and Active, but this is not required.

To select a primary port, click button 1 on a port to highlight it, then click

. Usually, the Primary port will also be your active port. Should your Primary port not be designated as the active port, it will switch to Backup/Inactive status when the circuit is initially enabled, but it will become the active port on the execution of the next test sequence (assuming it has a valid link at the time of testing).

To select the initially active port, click on a port (whether or not it has

already been selected as Primary), and click . The port designated as Active will be the initial port through which the link is checked. Should the active port fail, redundancy will start at the top of the port list and activate the next backup port, then work through the remaining ports in sequence should the first backup fail.

NOTES

All backup ports will be disabled as soon as you enable the redundant circuit. The ports remain disabled until they become active due to primary port failure. If you disable the redundant circuit, you must manually enable each backup port in that circuit.

Note also that if an active port fails, and then is repaired, it is not returned to active status until the circuit has been Tested (unless all other backup ports on the circuit have failed in the interim).

5.Once you have configured all the ports that compose the redundant circuit,

enable the circuit by clicking .

NOTE

Be sure to make all physical connections to the backup ports once the redundant circuit has been conÞgured and enabled.

To clear the settings in one circuit, highlight the Circuit Name that you want to

clear, and click on .
