Switch fabric compatibility
When equipping high-speed slots, it is imperative that the switch fabric of the circuit packs
located in Main 1 and Main 2 match. For example an LNW26B located in Main 1 may be
used with any LNW121B-159B DWDM circuit pack in Main 2, since both have partial
(up to 12 STS-1s) VT mapping. If circuit packs with different fabrics are inserted in Main
1 and Main 2, for instance, an LNW29 were to be inserted in Main 2 with an LNW26B
present in Main 1, an “unexpected circuit pack type” alarm would be raised.
Important!
LNW26B, LNW28, LNW77 and the LNW1xxB series circuit packs are
not supported in R7.1.
