CISCO C1-N9K-C9516-B3 Nexus 9000 Series Switches

C1-N9K-C9516-B3 Four-Fabric Starter Bundle

C1-N9K-C9516-B3 is the Cisco ONE Nexus 9516 package listing one supervisor, three power supplies, two system controllers, four fabric modules and three fan trays around the sixteen-slot chassis.

Large chassis, starter population

The 9516 supports up to sixteen line cards, ten power supplies, six same-family fabric modules and two supervisors. Four fabrics and three PSUs are a partial population, so scaling and redundancy must be designed before cards are installed.

Fabric identity must be explicit

The B3 description does not name an FM suffix. Capture the actual four fabric-module PIDs and match them to line-card generation, required per-slot bandwidth, supervisor and software release.

Power planning is material

A three-PSU bundle cannot be assumed to support a fully populated sixteen-slot chassis. Calculate normal and failure-state power for the intended cards, optics and fabric modules, then choose PSU count and input circuits.

Chassis-only comparison

is the 9516 chassis-only C1 PID. Choose B3 only when its listed starter components match the approved BOM.

Lifecycle and transfer

Cisco ended sale of the legacy Cisco ONE PID on March 1, 2021; vulnerability support ended February 29, 2024 and the last support date was February 28, 2026. Treat the C1 entitlement and any transfer rights as a separate acceptance item.
