5.2 Failover

The CBA750 can establish an uplink via any modems plugged into the USB or ExpressCard ports. Although all of these
devices may be plugged in, only one of them may establish a link at a time. If the WAN connection fails the router will
automatically attempt to bring up a new link on another device. This feature is called failover. You can also manually
disconnect and re-connect specific ports using icons in the Control column. The priority table can be saved permanently
via the Save button. Priority changes take effect immediately even if they are not saved.

5.2.1

WAN Interfaces

This section allows you to:



Change the failover order of devices

(aka interfaces)



Monitor their status



Take the active link down



Bring a link up on another device

The device at the top of the list has the highest
priority. This is the device that the router will
attempt to start when it boots up. If the link
cannot be brought up on this device, or if it fails
after boot-up, the router will attempt to bring the
link up on the next available device. Whenever a
link fails on a device, the router will always move
down to the next device down in the list, and wrap around again to the top.

Slot.

The slot is the physical port the modem is plugged into.
