Installation of APS Redundant Frame Assembly and Backcards

You can execute addyred 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.
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. See the dspyred description in the Cisco
WAN Switching Command Reference for details.
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 Backcards
The procedures in this section provide installation instructions for the SONET Automatic Protection
System (APS) Redundant Frame Assemblies and backcards. 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 and shown in Figure 13-9 and
Figure 13-10.
