Cisco 2500 Series Overview

The Cisco 2500 series is a multiprotocol router platform that is the basis for the following four

product types:

• A compact single LAN multiprotocol router

• A compact router/hub with 8, 14, or 16 Ethernet ports

• A compact router/access server with 8 or 16 asynchronous serial ports

• A dual LAN/multiprotocol router

This chapter provides an overview of the systems and their physical configuration, and contains the

following information:

• System Specifications

• Memory Configurations

The 2500 series is available in four fixed-configuration network-interface options, which are listed

in Table 1-1 and shown in Figure 1-2 through Figure 1-8.

The multiprotocol router is a fixed-configuration system that is ready for external network hardware connections and software configuration. The router system code operates from Flash memory by default. (For more information on system-code operation, see the section “System Operation Prerequisites” in the chapter “Preparing for Installation.”) The network interface types include Ethernet 802.3 (AUI and RJ-45), Token Ring 802.
