Figure 13-7 Y-Cable Connection
Terminating connections is possible at only a primary slot and not at a secondary slot. See the addcon
description.
On multiport card sets, each primary port is connected by a Y-cable to a secondary (redundant) port.
Port 1 of the primary card set must be paired to port 1 of the secondary card set, and so on. Figure 13-8
illustrates the cabling for a multiport card set.

If the secondary card set becomes active, the primary card set goes into the standby state. For the
primary card set to serve as a backup, it must be a complete set and not have failed status.
