Installation of APS Redundant Frame Assembly and Back Cards

You can execute the addyred command even if the primary and secondary slots are empty. If cards reside
in the primary and secondary slots, the system checks for card compatibility. Two types of
incompatibility can occur: back card and jumper or cable.
The following are the BPX mismatch types:
•
•
•
If incompatibilities exist, the message "Y-Cable Conflict" appears on screen. Specific conflicts are listed
in reverse video in the Y-Cable Redundancy screen. For information about the dspyred command, refer
to the Cisco WAN Switching Command Reference, Release 9.3.30.
Y-Cable redundancy is supported for both the UXM and BXM trunk cards at the edge of the ATM cloud.
Installation of APS Redundant Frame Assembly and Back Cards
The procedures in this section provide installation instructions for the SONET Automatic Protection
System (APS) Redundant Frame Assemblies and back cards. These may be used to provide line and card
redundancy for BXM OC-3 and OC-12 cards.
The APS protocols supported by the BXM are listed in Table 13-1.
