The N+1 Group column displays the type of group, broadband or narrowband,
that you have configured. As stated earlier in this chapter, the DXC-100PSX can
support multiple redundancy groups, including multiple broadband groups. Nb is a
narrowband redundancy group that can be established in slots 1 through 11, with
slot 1 configured as the secondary slot; Bb-2 is a broadband redundancy group
that can be established in slots 1 through 7, with slot 7 configured as the
secondary slot; Bb-1 is a broadband redundancy group that can be established in
slots 8 through 11, with slot 11 configured as the secondary slot.
The pluses (+) and minuses (-) you see displayed on the screen (1 Figure 3-18 )
distinguish the cards configured as part of an active Redundancy Group and the
card that has been switched over.
To qualify for the (+), the configured device type must be correct, the slot
redundancy in the Slot Configuration Menu must be
enabled , the NDR group must
have a configured and
enabled redundant device, and the Protection Switch must
be
Online .
The (-) indicates the card is not just a part of an active Redundancy Group but
that the device has switched over to the redundant module.
