Cisco 2500 Series

Cisco 2500 Series

Product Overview

The Cisco 2500 series routers provide a variety of models designed for branch office and remote site environments. These routers are typically fixed configuration with at least two of the following interfaces:

Key Features and Benefits

Cisco 2500 routers come with Flash EPROM technology for simplified software maintenance. These systems support a variety of Cisco IOS software feature sets, so you can choose a feature set that supports your specific protocol environment. The software feature sets range from an IP and bridging-only to the full array of Cisco`s software functionality, including APPN and RMON.

Mission-specific models contain less memory and less hardware functionality to support a subset of protocols. Each mission-specific model can be upgraded to full router capability by downloading a new Cisco IOS software feature set and, if necessary, adding memory.

Cisco 2500 series models can be divided into the following categories:

Specifications

Hardware

All the Cisco 2500 series models support the features listed in the following table.

However, depending on the Cisco IOS release that shipped with the system, it might require more memory. Refer to the "Cisco IOS Software" chapter for the minimum Flash memory required for each feature set.

Options

The Cisco 2500 series routers are discussed in the following sections:

  • Memory Options
  • Single LAN Routers
  • Mission-Specific Routers
  • Router/Hub Combinations
  • Access Servers
  • Dual LAN Routers
  • Modular Routers
  • Hardware Product Numbers

Memory Options

All Cisco 2500 models include a minimum of 8 MB of Flash memory, except for the mission-specific routers which include 4 MB or 8 MB of Flash memory, depending upon the Cisco IOS software release you order. Additional Flash memory can be purchased to allow for dual banking or potential future code growth.

There are two types of DRAM memory in the Cisco 2500 series routers: primary and shared (packet). Primary memory is used to store the operating configuration, routing tables, caches, and queues. Shared memory is used to store incoming and outgoing packets. In the table below, the physical configuration column lists the amount of DRAM SIMM memory supported. The system usage column lists how the system allocates the total DRAM memory installed.

Table 5-83: Shared and Primary DRAM Memory-Cisco 2500 Series
  Physical Configuration System Usage
Total DRAM Memory DRAM SIMM Shared DRAM Memory Primary DRAM Memory
4 MB 4 MB 2 MB 2 MB
8 MB 8 MB 2 MB 6 MB
16 MB 16 MB 2 MB 14 MB


Hardware Product Numbers

The Cisco 2500 series offers the hardware, memory, and NPM cable options listed in the following table. If a product number ends with an equal sign (=), the item can be ordered only as a spare. If a product number does not end with an equal sign, the item can be ordered as a spare or as a configurable part of a system order. Other hardware options can also be ordered through the Cisco authorized reseller channel.

Note For options that apply to most systems, refer to the "Cables and Transceivers" or "Power Supplies and Power Cords" chapters later in the catalog.

Single LAN Routers

Models 2501, 2502, 2503, 2504, 2520, 2521, 2522, and 2523 (see through ) contain the common Cisco 2500 series features listed in the following table. In addition, these models support the network interfaces listed in Table 11-90.

Note This section discusses standard models. The mission-specific models are described in the "Mission-Specific Routers" section later in this chapter.

Mission-Specific Routers

Mission-specific routers are entry-level routers that are based on standard Cisco 2500 hardware. However, mission-specific routers contain less memory than standard models and run reduced software images designed for CFRAD, LAN FRAD, and ISDN applications. These reduced software images disable unused ports. Mission-specific routers can be upgraded to full standard-model functionality by purchasing additional software and memory.

Access Servers

Models 2509, 2510, 2511, and 2512 are designed to function as access servers for remote node and asynchronous/synchronous routing. For complete information, refer to the "Access Servers" chapter later in the catalog.

Dual LAN Routers

Models 2513, 2514, and 2515 provide higher-density LAN support and include all the common features listed in Table 11--89. In addition, these models support the interfaces listed in the table below.

Modular Routers

Models 2524 and 2525 provide LAN and WAN access in a low-cost modular router platform that can grow with your internetworking needs. The Cisco 2524 offers an Ethernet (AUI or 10BaseT) LAN connection, and the Cisco 2525 offers a Token Ring (STP or UTP) LAN connection. Both routers can accommodate up to three WAN modules-two synchronous serial and one ISDN.

The choice of synchronous serial WAN modules is as follows:

  • 2-wire, switched, 56-kbps DSU/CSU
  • 4-wire, 56/64-Kbps DSU/CSU
  • Fractional T1/T1 DSU/CSU
  • Five-in-one synchronous serial

Note The five-in-one synchronous serial WAN module gets its name from the five types of signaling it supports, which include: EIA/TIA-232, EIA/TIA-449, V.35, X.21 and EIA-530. You can order a DB-60 shielded serial transition cable. The router end of the cable has a DB-60 connector; the other end of the cable has the appropriate connector for the standard interface you specify.

The choice of ISDN WAN modules is as follows:

  • ISDN BRI
  • ISDN with integrated NT1 device

The ISDN WAN modules are keyed so that you cannot insert them into the synchronous serial WAN slots. A blank slot cover is installed over unused slots.

1. Mission-specific router. Mission-specific routers are based on standard Cisco 2500 hardware, but they contain less memory and run reduced Cisco IOS images that disable unused ports and support a subset of protocols. By adding software, and possibly memory, mission-specific routers can be upgraded to full standard router functionality.

2. See the "Access Servers" chapter later in this catalog, for more information.
