Cisco 10000 Series Router Software Configuration Guide

Chapter 14 Configuring Automatic Protection Switching
Single-router Automatic Protection Switching
When you associate slots, the software pairs an odd-numbered slot with the next higher even-numbered
slot:
• Odd-numbered slot—Holds the primary card, or working card
• Even-numbered slot—Holds the secondary card, or protect card
Figure 14-2 shows the redundant slot pairings in the Cisco 10008 chassis.

Note Only slots 1 and 2 and slots 3 and 4 in the Cisco 10005 chassis can be used for APS redundancy because
slot 5 does not have an associated higher, even-numbered slot.
