Cisco 7500 Series

Product Overview

The Cisco 7500 series is Cisco's premier high-end platform of multiprotocol routers, which include the Cisco 7505, the Cisco 7507, and the Cisco 7513. These systems combine Cisco Systems' proven software technology with exceptional reliability, availability, serviceability, and performance features to meet the requirements of today's most mission-critical internetworks. The Cisco 7500 series provides information system professionals with the flexibility they need to meet the constantly changing requirements at the core and distribution points of the internetwork.

The Cisco 7505 features a high-speed Cisco Extended Bus (CyBus); the Cisco 7507 and Cisco 7513 feature dual CyBuses. Network interfaces reside on modular interface processors, which provide a direct connection between the CyBus and the external network, and support any combination of ATM, channelized T3, Ethernet, Fast Ethernet, FDDI, IBM channel attachment, multichannel E1 and T1, HSSI, synchronous serial, Token Ring, and Packet OC-3 interfaces. For more information about interface processors, see the "Interface Processors for the Cisco 7000 Family" chapter.

The Cisco 7505 (see Figure 7-2) contains five slots (one slot for the Route Switch Processor [RSP], and four slots for interface processors); the Cisco 7507 (see Figure 7-3) contains seven slots (two slots for RSPs, and five slots for interface processors); and the Cisco 7513 (see Figure 7-4) contains thirteen slots (two slots for RSPs, and eleven slots for interface processors).

The Cisco 7500 series runs the industry-leading networking software, Cisco IOS software. Cisco IOS software assures robust, reliable internetworks by supporting both LAN and WAN protocols, optimizing WAN services, and controlling internetwork access. In addition, Cisco IOS software allows centralized, integrated, and automated installation and management of internetworks.

The Cisco 7500 series offers software feature sets and feature licenses, which allow you to select the package that best meets your needs. You can select from fifteen feature sets, which can be enhanced with additional feature licenses. If requirements change in the future, you can upgrade to a higher level feature set and add another feature license.

The reliability, availability, and serviceability features of the Cisco 7500 series include the following:

Standard Features

The Cisco 7500 series base system includes the following standard features:

Hardware

Hardware for the Cisco 7500 series includes interface processors, memory, serial cables, a second power supply (Cisco 7507 and 7513 only), accessories, and upgrades for the Route Switch Processor (RSP). Table 7-22 lists hardware option product numbers for the Cisco 7500 series.

Route Switch Processors

A Cisco 7500 series system requires at least one Route Switch Processor (RSP), which can be ordered in three ways: as part of an initial system, as a spare, or as an upgrade. The RSP can be ordered with your choice of 32-, 64-, or 128-MB DRAM and one or two Flash memory cards, which are available in 8-, 16-, or 20-MB densities. The price of an RSP includes 32 MB of DRAM and an 16-MB Flash memory card. For more information about the RSP Flash memory cards, see a later section, "Flash Memory Cards."

RSP1

Cisco IOS software images reside in Flash memory, which is located either on the RSP1, in the form of a SIMM, or on up to two Flash memory cards. Storing software images in Flash memory enables you to download and boot from upgraded images remotely. This eliminates the need for removal and replacement of ROM devices when updating software. For more information about the RSP1's Flash memory card, see a later section, "Flash Memory Cards."

Table 7-16 summarizes the memory components of the RSP1.

RSP2

Cisco IOS images reside in Flash memory, which is located either on a SIMM on the RSP2 or on up to two Flash memory cards. Storing Cisco IOS images in Flash memory allows you to download and boot from upgraded images remotely. This eliminates the need to remove and replace ROM devices for software updates.

Table 7-17 summarizes memory components of the RSP2.

RSP4

The RSP4 contains the central processing unit (CPU) and most of the memory components for the router. Cisco IOS software images reside in Flash memory, which is located either on the RSP4, in the form of a SIMM, or on up to two PCMCIA Flash memory cards. These cards are inserted into the two PCMCIA slots (slot 0 and slot 1) on the front of the RSP4.

Table 7-18 summarizes memory components of the RSP4.

Flash Memory Cards

In Cisco 7500 series routers, Flash memory cards can be used to store and boot Cisco IOS images and/or system configurations. A Cisco 7500 series router can also be used as a TFTP server, with the Flash card memory used to store other files such as software and microcode images for other systems. Cisco recommends using one card for image storage and another for configurations. The number of system images that can be stored on the card depends both on the Flash card size and the file size.

The Flash memory card is available in 8-, 16-, or 20-MB densities. The card is an Intel Series 2+ Flash memory card, which conforms with Personal Computer Memory Card International Association (PCMCIA) format. The Flash memory card that is shipped with the system contains a software image; the same Flash memory card ordered as a spare is shipped blank and must be formatted before use.

Refer to Table 7-22 for the product numbers for Cisco 7500 series Flash memory cards.

Memory Options

This section discusses memory options and recommendations for the Cisco 7500 series routers.

DRAM Guidelines

• For the RSP1 or RSP2, DRAM is contained in four SIMM slots (two banks of two SIMMs each).

• For the RSP1 or RSP2, bank 0 must be greater than or equal to bank 1.

• For the RSP4, DRAM is contained in two DIMM slots

• Do not mix DRAM sizes within a bank (except on the RSP4).

Refer to Table 7-19 for DRAM size recommendations based on the size of your network. Then, consult with your Cisco system engineer to determine the recommended DRAM configuration for your unique network.

Refer to Table 7-20 for DRAM size requirements for a Cisco 7500 series router running Cisco IOS Release 11.1.
