The Cisco 2951 is a 2900 Series router with two service module slots, and its CISCO2951/K9 base model has three onboard 10/100/1000 ports, four EHWIC slots, three DSP slots, two service module slots, one ISM slot, 256 MB compact flash, 512 MB DRAM and IP Base preloaded. One onboard port runs as SFP in place of its RJ-45 port. The chassis is 2RU, measures 3.5 x 17.25 x 18.5 in., weighs 29 lb with the AC supply and is for NEBS environments.
Two SRE service modules (SRE 700, 710, 900 or 910) fit the service module slots, and the ISM slot adds one SRE 300, for three SRE modules at most. A double-wide service module takes both slots. PVDM3 modules from PVDM3-16 to PVDM3-256 fit the DSP slots, and up to four EHWIC-1GE-SFP-CU cards run on Cisco IOS Software Release 15.1(4)M. The router handles 250 SRST sessions and 150 CME sessions.
Memory differs from the other 2900 models. A 512 MB DIMM sits in one of two memory slots, upgrades raise that DIMM or fill both slots, and the two slots can hold different sizes. The MEM-2951 numbers are the 2951’s own, and the DRAM numbers of the Cisco 2901, Cisco 2911 and Cisco 2921 do not fit it. Two compact flash slots take cards up to 4 GB. The 2951 also has its own Cisco IOS universal image, S2951UK9-15014M.
The power supplies are PWR-2921-51-AC, PWR-2921-51-POE and PWR-2921-51-DC, with up to 370 W of endpoint PoE from the PoE supply. The RPS-ADPTR-2921-51 adapter connects a Cisco RPS 2300 for redundancy or for 750 W PoE boost. The fan assembly is shared with the 2921. SL-29-DATA-K9, SL-29-UC-K9 and SL-29-SEC-K9 activate Data, Unified Communications and Security features. Routers are also in the Cisco router category, and the whole range is on the networking page.
