ISR4451-X/K9 is the Cisco 4451-X Integrated Services Router in the Cisco 4000 Family. Aggregate throughput is 1 Gbps by default, 2 Gbps with the performance licence and more than 4 Gbps CEF-only with the boost licence.
Its onboard ports are four 10/100/1000 interfaces, with four RJ-45 and four SFP connectors. The 4451-X has three NIM slots, two enhanced service-module slots (one double-wide while no single-wide SM-X modules are fitted) and one onboard ISC slot.
Control and services plane DRAM is 4 GB by default and expands to 16 GB, data plane DRAM is 2 GB, and flash is 8 GB by default and expands to 32 GB. Two external USB 2.0 type A slots sit beside USB mini-B, RJ-45 serial and RJ-45 auxiliary console ports.
Power supplies are internal AC, DC or PoE, with a redundant option. The AC supply is rated at 450 W maximum without PoE and typical draw with no modules is 158 W. The DC supply is rated at 437 W. The PoE supply reaches 1000 W with PoE redundancy or 1450 W with PoE boost, with endpoint PoE of up to 500 W with redundancy or 950 W with boost.
