Cisco Internal Services Module W/ Services Ready Engine | ISM-SRE-300-K9

The Cisco ISM-SRE-300-K9 is part of the Cisco Services-Ready Engine (SRE) family and is designed to enhance branch-office IT by integrating applications directly into Cisco ISR G2 routers. This module offers Gigabit Ethernet connectivity to the router backplane, eliminating the need for external network interfaces. It is compatible with a broad range of ISR G2 platforms, including the Cisco 1941, 2901, 2911, 2921, 2951, 3925, and 3945 routers. The ISM-SRE-300-K9 runs with Cisco IOS Software Release 15.0(1)M and supports a wide range of applications, from security to network optimization. However, it does not support hot-swappable hard drives or RAID, differentiating it from higher-end SRE models.

The ISM-SRE-300-K9 is ideally suited for branch offices or remote sites where integrated services need to be deployed without additional hardware. It enables the hosting of Cisco or third-party applications such as WAN optimization, security tools, or unified communications on the same router hardware, significantly reducing operational costs and space requirements. The tight integration with ISR G2 platforms makes it an optimal solution in scenarios requiring reliable, embedded compute resources without external cabling, particularly in secure, low-maintenance network environments.
