Important! — A PME-412 line card must NOT be collocated within the same card pair with
a PME-216i line card. A PME-412 collocated with a PME-216i in a card pair will not
support cross-card Flow Domains, Link Aggregation Groups, TESI groups, Ethernet
Ring Protection, and cannot operate as a bridge in a Spanning Tree configuration.
In a Z77 shelf, PME-412 card pairs or PME-216i card pairs can be installed in slots 3/4,
5/6, 7/8, 9/10, 11/12, 13/14, and 15/16. In a Z33 shelf, PME-412 card pairs or PME-216i card
pairs can be installed in slots 1/2, 3/4, and 5/6. In a Z22 +24V shelf, PME-216i card pairs
are installed in slots 1/2. In a Z22 -48V shelf, PME-216i card pairs or PME-412 card pairs
can be installed in slots 1/2.
Note that a PME-412 and a PME-216i can be installed in adjacent even/odd slots, for
example in a Z77 shelf in slots 4 and 5 respectively, but they cannot operate as a card
pair.
Important! – A PSW-10G10 or PSW-618 line card must NOT be installed in the same card
pair slots with a PME-412 or PME-216i line card.
LAD and WSS Link Connections
In a ring configuration, LAD and WSS odd slot fibers should be connected to even slot fibers in a clockwise
direction. For example, a LAD transmit fiber in a Z33 shelf in slot 5 should be connected to a receive fiber in
the adjacent Z33 shelf in slot 6.
In a linear chain configuration, LAD and WSS odd slot fibers should be connected to even slot fibers in the
adjacent shelf in a left to right direction.
Important! – If using an attenuator, place it on the Receive (RX) port of the LAD/WSS card.
Do NOT place it on the Transmit (TX) port.
Network Configuration Examples
The following graphics provide examples for the recommendations described above.
The figure below shows six examples of slot and line card assignments in linear chain networks. All of the
examples follow the basic recommendation of installing LAD and WSS cards from the top down in Z33
shelves and right to left in Z77 shelves. Additionally, Cyan recommends the "transmit" transport LAD or
WSS card be installed in an odd slot and the "receive" transport card in an even slot.
