Broadband Redundant Device
To view information on the Broadband redundant device in slot 11 (Broadband
Redundancy Group 1) or 7 (Broadband Redundancy Group 2), invoke the
Nest
Summary Menu.
Position your cursor on the specific broadband redundant device,
in this case slot 11, and press <Enter>. The following screen appears:

As you can see from the device’s Main Menu, shown in 7
Figure

, a switchover
has occurred and the DT3 or DE3 redundant device is protecting the DT3 or DE3
primary device resident in Slot 10; the redundant device in slot 11 is view-only. If
a switchover had not occurred, that field would read
“none”
. Consequently, if you
displayed the slot information for a primary device configured in a Broadband
Redundancy Group, the
“Protected Slot”
field would not be there.
From the screen shown in

Figure

, you can access utilities, view the device’s
configuration, redundancy state, and display module identification. With the
exception of viewing the redundancy state, you can go to the relevant
narrowband or broadband device chapter to learn more about the View
Configuration, Diagnostics, Utilities,
and the
About
submenus and their
functionality.
N+1 Redundancy State
The following N+1 Redundancy States are available when you configure the slot:
•
Enable
- The system will continue to display information about the N+1
Redundancy logic, even though the redundancy state for the specific slot
remains enabled.
•
Disable
- The cards in a redundant group are no longer actively protected;
thus a switchover
cannot
occur.
•
Freeze
- Does not permit the N+1 Redundancy logic from updating the
system; thus, the last result of the N+1 Redundancy is displayed.
In most cases, there will be a one-to-one correspondence with what you set as
the N+1 Redundancy State and the actual state accepted by the DXC-100. In the
case where this does not occur, the N+1 Redundancy State is
enabled
and the
N+1 Redundancy State reflected on the Nest Summary menu is
frozen
due to a
missing Protection Switch cable.
