Cisco 2921 and 2951 Router Power Supply

The KHACHIMO WR-2921-51-AC is a replacement ATX power supply built for Cisco 2921 and 2951 series routers. Each unit is tested before shipment to confirm reliable operation. It suits network administrators who need a direct-fit spare for these specific router models.

51-volt output capacity for targeted router support

The supply delivers the 51-volt rail required by the 2921 and 2951 chassis, providing enough headroom for normal routing loads with installed modules. It does not support other Cisco platforms or higher-wattage configurations that demand additional power rails. Builders needing redundant or hot-swap capability should verify chassis compatibility before purchase.
