Dual Cisco SCE8000 GBEs Topology

In this topology, two Cisco SCE8000 GBEs are connected, providing full redundancy through cascading
the two Cisco SCE8000 GBEs. The Cisco SCE8000 GBEs must be inline.
When installing a cascaded system, it is extremely important to follow the sequence of procedures
Note
outlined in
When two Cisco SCE8000 GBEs are used, the SPAs in subslots 0 and 1 are connected to the links, while
the SPAs in subslots 2 and 3 are the cascade ports that are used for communicating between the two Cisco
SCE8000 GBEs.

Cascaded Systems, page
8-port GBE SPAs are used in subslots 0 and 1 and are connected to the traffic links. With eight traffic
links in each SCE8000 GBE, this provides a total of 16 traffic links.
1-port 10 GBE SPAs are used in subslots 2 and 3 to provide the cascade ports for communicating
between the two SCE8000 GBE s.
A topology with only one 8-port GBE SPA in subslot 0 and one 1-port 10GBE SPA in subslot 2 is
supported.
A topology with only one 8-port GBE SPA in subslot 0 and two 1-port 10GBE SPAs in subslots 2
and 3 is not supported.
The two SCE8000 GBE platforms are identified in relevant CLI commands by the sce-id parameter
(see sce-id Parameter, page
