C9K-PWR-1500WDC Description
The C9K-PWR-1500WDC is a Cisco Catalyst 9500X Series 1500W DC platinum certified power supply module for C9500X-28C8D and C9500X-60L4D switches in DC-powered racks. The supply takes -40 to -72 VDC through a C10-638977-00 Amphenol connector, reaches 94% efficiency at -48 to -60 VDC and 50% load, and has a 12V main output rated at 125A. The module is hot-swappable, and a blank cover stays in the second slot when only one supply is fitted.

Application Scenarios
A C9500X-28C8D in a telecom or data center room with a DC power plant takes its power through this supply instead of an AC circuit.
A C9500X-60L4D can pair this supply with a C9K-PWR-1500WAC, one slot on a DC plant and the other on an AC circuit, because the platform supports AC and DC supplies together.

C9K-PWR-1500WDC is the DC-input 1500W supply for Catalyst 9500X systems, taking -40 to -72 VDC through a C10-638977-00 Amphenol connector, while C9K-PWR-1500WAC takes 90 to 264 VAC through a C22 receptacle, so racks with an AC feed order C9K-PWR-1500WAC instead. C9K-PWR-1600WDC-R is also a -40 to -72 VDC supply but rated 1600W, with a different Amphenol connector, C10-638976-000, and a 133A 12V main output against 125A. It is the DC option for C9500-32C, so C9500-32C systems need C9K-PWR-1600WDC-R and Catalyst 9500X systems need C9K-PWR-1500WDC. Holdup time is 2 ms on C9K-PWR-1500WDC against 5 ms minimum on C9K-PWR-1600WDC-R.
