DXC-100PSX Setting Up Multiple NDRGs 3-5
3.3 Setting Up Multiple NDRGs
While portions of the broadband and narrowband redundancy groups are
mutually exclusive, you can set up combinations of both broadband and
narrowband NDRGs, as well as multiple broadband NDRGs.
Figure 3-6. Rear View of DXC-100PSX showing possible Narrowband and Broadband
NDRGs
Up to three NDRGs (i.e., any combination of broadband and narrowband) can be
set up in the DXC-100 nest, see illustration above:
• The narrowband devices can reside in slots 1 to 11, with slot 1 holding the
narrowband redundant device
• Broadband group 1 devices can reside in slots 8 to 11, with slot 11 holding
the broadband redundant device
• Broadband group 2 devices must reside in slots 1 to 7, with slot 7 holding the
broadband redundant device.
Again, all primary slots must be configured and enabled in order for the
switchover to occur. The allowed combinations of redundancy groups and their
slots are listed in
3 Table 3-3 .
