It is important to note here that there is no priority structure to an Redundancy
Group. In other words, the first primary card in the Redundancy Group to fail is
the one that will be switched. Should another primary card in the Redundancy
Group fail while the redundant card is in use,
another switchover will not take
place
.
To establish a Broadband Redundancy Group, you must go to the Slot
Configuration Menu. Refer to the
System Configuration chapter in the DXC-100
User Guide for specific details on configuring a slot. For Broadband Group 1,
configure slot 11 for the broadband redundant device; and configure slots 8
through 10 with broadband primary devices. For Broadband Group 2, configure
slot 7 for the broadband redundant device; and configure slots 1 through 6 with
broadband primary devices.
You do not have to configure all of the slots (8, 9 and 10 for Broadband
Redundancy Group 1, and 1 through 6 for Broadband Redundancy Group 2) in the
DXC-100 nest with the broadband devices but note that any device other than a
broadband device will not be recognized as part of that Broadband Redundancy
Group, and therefore is not protected.
Configuring a Broadband Redundancy Group is detailed on the following pages.
