Cisco 2500 series

The following modules were available: These routers were repackaged versions of the 2500 specifically to be sold through channel partners to small and medium businesses that needed a greater ease of setup.

They are characterized by a light grey/cream colored case compared to the standard dark grey colouring.

'Mission-specific' models contained less memory and less hardware functionality, and were tailored to support only a subset of protocols.

Pricing (Circa 1995) – 2520CF US$1,595 to 2523LF US$3,995 The 2500 series uses a single 72pin FPM (70ns) SIMM with parity, and can take a maximum of 16 MB.

An erasable, programmable read-only memory (EPROM) of 2 MB in size was used to permanently store the startup diagnostic code (ROM Monitor), and RxBoot.

On the 2500 software upgrade required booting to a BOOTROM OS with reduced functionality to have write access on the flash file system.

The BOOTROM OS did not support Tokenring interfaces, making software upgrade more complex.

As a result, the flash file systems on those routers was read/write during operation and software installation could be done during runtime.
