Many card sets support Y-cable redundancy. This feature requires an extra set of cards and a Y-cable. A set of commands exists to specify, delete, and display Y-cable redundancy. For instructions on setting up Y-cable redundancy, refer to the setup section for the specific card set.

Note FRM and NTM front cards exist in one and two-piece versions. The two-piece card uses an ACM1. Refer to the Cisco IGX 8400 Series Reference for details.

A Cisco IGX node can support a configuration of up to 32 trunks.

Caution Connector pins must align with receptacles. Before card insertion, make sure that pins are straight and that card connectors and the backplane align. Insert the card gently. It might be necessary to push the edge of the card slightly to one side for alignment (this might require removing cards).
