System Configuration and Operation
WAN Card Redundancy
Therefore if a situation occurs (such as a shelf restart or power cycle), an 801460 card in the
RDNT slot will swiftly come into service, and therefore take over traffic for an 801070 which
is still booting up. When mixing cards, the 801470 card should be used in the RDNT slot (W4)
to prevent undesired protection switches in case of a system re-initialization.
If a standard WAN card is in slot W4, the system does not support WAN redundancy.
In cross-connect systems, switching always occurs on both ports of a WAN card. Therefore,
both ports of all active WAN cards must have the same plug-in modules as the redundant-card
ports.
Figure 5-78 shows a System Main Screen for a cross-connect system with WAN card
redundancy. In this example, the DSX ports of the WAN cards in slots W1, W2, and W3 are
backed up by the DSX ports of the WAN card in slot W4. The redundant WAN card in slot
W4 takes over for the first active WAN card that fails.
