3-6 Setting Up Multiple NDRGs DXC-100PSX
If a primary device in an Redundancy Group is being protected by a redundant
device, do not remove it from the group if a switchover has occurred.
Setting up a Narrowband Redundancy Group
A Narrowband Redundancy Group can contain up to
eleven
configured
narrowband devices. These devices reside in
slots 1 through 11
. It is not
necessary to have all narrowband devices in the nest be part of the Narrowband
Redundancy Group. Narrowband devices not configured as part of the
Redundancy Group
will not
be part of the Redundancy Group by default. You
must
actually configure
the device to be part of the Redundancy Group.
The Narrowband Redundancy Group can contain only one redundant device,
which must reside in
Slot 1
. If the redundant device is not in Slot 1, or has not
been configured as a part of the Redundancy Group or enabled, then the
Redundancy Group switchover
will not
occur.
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 Narrowband 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. Configure Slot 1 for the
narrowband redundant device; and configure slots 2 through 11 with narrowband
primary devices.
You do not have to configure every slot in the DXC-100 nest with narrowband
devices, but note that any device other than a narrowband device will not be
recognized as part of that Redundancy Group, and therefore is not protected.
Configuring a Narrowband Redundancy Group is detailed on the following pages.
