Description

The Cisco SRE 300 Internal Service Module is a Services-Ready Engine blade for Cisco ISR G2 routers. It installs inside the router chassis and hosts Cisco, third-party and custom branch-office applications on its own processor, memory and flash storage, independent of the host router's resources. It suits branch-office and small-to-medium enterprise sites looking to consolidate separate servers or appliances onto the router.

The SRE 300 ISM uses a 1.06 GHz Intel processor with 512 MB DRAM and a 4 GB internal USB flash memory module. There is no hard disk and no RAID support. Connectivity to the router backplane is Gigabit Ethernet, with no external network interfaces. Maximum power consumption is 20 W, drawn from the host router chassis, so no separate power supply is needed.

It is supported on Cisco 1941, 2901, 2911, 2921, 2951, 3925 and 3945 ISR G2 routers, with one ISM per chassis, and needs router IOS Release 15.0(1)M or later. It is not supported on the 3925E or 3945E. Typical roles include an entry-level Wireless LAN Controller supporting up to 10 access points, Cisco Unity Express voicemail, or custom applications on Cisco AXP. The module hardware needs no licence, while applications are licensed separately.
