The Cisco 3945 is a 3900 Series Integrated Services Router. Its CISCO3945/K9 base model has a Services Performance Engine SPE150, three onboard 10/100/1000 ports, four EHWIC slots, four DSP slots, four service module slots, one ISM slot, 256 MB compact flash, 1 GB DRAM and IP Base preloaded. Two of the three ports can run as SFP in place of the RJ-45 port. The other model in the series, the Cisco 3925, has two service module slots and the SPE100, and Cisco rates services throughput at 150 Mbps for the 3945 and 100 Mbps for the 3925. The chassis is 3RU, measures 5.25 x 17.25 x 18.75 in., weighs 39 lb with the AC supply and is for NEBS environments.
The EHWIC slots pair into up to two double-wide slots, and up to four EHWIC-1GE-SFP-CU cards run on Cisco IOS Software Release 15.1(4)M. One double-wide service module can take two service module slots. Up to five SRE modules fit, four service modules (SRE 700, 710, 900 or 910) in the service module slots and one SRE 300 in the ISM slot. PVDM3 modules from PVDM3-16 to PVDM3-256 fit the four DSP slots. SM-NM-ADPTR adapts network modules to a service module slot, and PVDM2-ADPTR adapts a PVDM2 to a PVDM3 slot.
The SPE150 is field-replaceable and supported only on 3945 platforms. The 1 GB of DRAM is two matched 512 MB DIMMs, and the router does not take different densities or a single DIMM. Two compact flash slots hold cards up to 4 GB. Dual internal supplies can be AC, PoE or DC, with PWR-3900-AC, PWR-3900-POE and PWR-3900-DC as the primary numbers and a /2 number for the secondary supply. Two supplies provide redundancy or increased PoE, and one PoE supply gives up to 520 W for endpoints.
One universal Cisco IOS image, S39UK9-15014M, runs on the 3945 and 3925. SL-39-DATA-K9, SL-39-UC-K9 and SL-39-SEC-K9 activate Data, Unified Communications and Security features. The Cisco 2951, Cisco 2921 and Cisco 2911 pages cover other Cisco ISR G2 routers. Routers are also in the Cisco router category, and the whole range is on the networking page.
