Why each option
To recognize only Cisco UCS chassis with four connections between each IOM and the Fabric Interconnect pair, the Chassis/FEX Discovery Policy must be configured with the 'Action: 4-link'.
The Chassis/FEX Discovery Policy in Cisco UCS Manager controls how a newly connected UCS chassis is recognized and managed based on its uplink connectivity to the Fabric Interconnects. Configuring the 'Action' to '4-link' ensures that only chassis with four links per IOM connected to the Fabric Interconnects are discovered and brought under management, matching the requirement for specific cabling redundancy.
The Redundancy Action within the Chassis/FEX Discovery Policy typically relates to chassis numbering (e.g., N, N+1) and not the number of physical links per IOM.
The Rack Management Connection Policy is used for managing rack servers and their management interfaces, not for discovering UCS chassis based on IOM uplink count.
The Power Policy manages power redundancy and consumption within a chassis, which is unrelated to the discovery of chassis based on physical connectivity.
The Rack Server Discovery Policy is used for discovering individual rack-mount servers, not for the discovery and management of UCS chassis containing IOMs and blade servers.
