* 177D Apparatus Blanks are required in all unequipped Function unit and Growth slots to provide proper air flow for cooling.
† LNW6 and LNW7 are not compatible with VLF Mains
‡ In G1,G2 LNW20 only supports portless operation.
** Only optical ports on the LNW74 can be used in growth slots.
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.
