Figure 3-11. D8E1T1 Secondary Device
Since slot 1 is established as the redundant device, it is only viewable as a status
screen.
As you can see from the D8E1T1 device’s Main Menu (
4 Figure 3-11 ), a switchover
has occurred and the D8E1T1 redundant device is protecting the D8E1T1 primary
device resident in slot 2. If a switchover had not occurred, the
Protected Slot field
would read
“none” . Consequently, if you displayed the slot information for a
primary device configured in a Narrow- band Redundancy Group, the
Protected
Slot
field would not be there.
From the screen shown in
5 Figure 3-11 , you can view the device’s configuration,
access utilities, view the redundancy state, and display module identification.
With the exception of viewing the redundancy state, you can go to the relevant
narrowband or broadband application module chapter to learn more about the
View Configuration, Diagnostics, Utilities, and the About sub- menus and their
functionality.
The
N+1 Device Redundancy submenu can be accessed from both the device’s
Main Menu and the Diagnostics submenu.
Setting Up a Broadband Redundancy Group
The Broadband Redundancy Group can contain up to eleven configured
broadband devices. These devices reside in
slots 8 through 11 for Broadband
Redundancy Group 1, and in
slots 1 through 7 for Broadband Redundancy Group
2. Like the Narrowband Redundancy Groups, it is not necessary to have all
broadband devices in the nest be part of a Broadband Redundancy Group.
broadband devices not configured as part of the Redundancy Group
will not be
part of the Redundancy Group by default. You must a
ctually configure the device
to be part of the Redundancy Group.
Each Broadband Redundancy Group can only have one Broadband Redundant
Module. This device must reside in
slot 11 for a configured Broadband 1
Redundancy Group, and in
slot 7 for a configured Broadband 2 Redundancy
Group. If the device is not in those respective slots or if it has not been
configured as a part of the Broadband Redundancy Group or enabled, then the
Redundancy Group switchover
will not occur.
