Table 1-10 describes the T3 interface card LEDs.
Access Redundancy Module Interface Card
To enable N+1 redundant operation, you must install an access redundancy
module (ARM) interface card in slot 5 of the chassis. The redundant AP card in
slot 5 can then assume the processing duties of a failing AP card. With an ARM
card installed in interface card slot 5 and a hybrid M13 and clear-channel DS3
CAP card installed in processor card slot 5, the Versalar 15000 supports failover
of mixed clear-channel and channelized T3 configurations.
If a CAP card is installed in processor card slot 5, the N+1 and Slot LEDs indicate
which T3 interface card is being serviced. For more information about N+1
redundancy and failover, see Managing and Troubleshooting the Versalar Switch
Router 15000.
