Keep Catalyst 9600 infrastructure supplied with the DC power capacity required for dense enterprise switching. This 2,000 W Cisco power supply is intended for the Catalyst 9600 Series, where chassis-level power planning must support sustained network throughput, redundancy strategies, and long service windows. In large campus cores, aggregation layers, and data center edge deployments, the power subsystem is not a commodity component. It is part of the availability model. A Cisco-branded supply for the 9600 platform helps preserve alignment with the chassis design and the operational expectations of teams standardizing on Cisco switching. That matters when procurement is tied to lifecycle consistency, supportability, and predictable deployment behavior. This unit is a fit for organizations that need DC-powered infrastructure and want to keep the power path inside the same vendor ecosystem as the switch platform. For network teams, that reduces ambiguity during refreshes, spares planning, and maintenance windows. It is the kind of component chosen to protect uptime, not to chase low upfront cost.
