The figure below shows an example of another typical Z33/Z77 ring configuration with odd to even slots
connected in a clockwise direction. In this example, Site 2 has only WSS cards installed in a Z33 shelf. In
this shelf the WSS-402 cards must be installed in slots 1 and 2 to act as controller cards. The WSS cards in
the Z33 shelf at Site 3 are also installed in slots 1 and 2 to match the slots at Site 2.

Fiber Patches
Fiber patches on LAD and WSS cards should be connected from even card slots to even card slots and odd
card slots to odd card slots.
Fiber patches on multi-port line cards (for example, PME-412, PME-216i, DTM-8, MSE-1482, SFT-8, or
SFT-10G16) should be connected from even ports to even LAD and WSS slots and odd ports to odd LAD
and WSS slots.
