Introduction

This document explains how to replace the main memory DRAM or SDRAM modules on the network processing engine (NPE) or network services engine (NSE). It also explains how to install, reformat, and copy images onto and between the CompactFlash Disks and between Flash Disks or PC cards that reside in the I/O controller PC card slots. Read this entire document before upgrading the memory in your router. For CompactFlash Disk or Flash Disk memory information, see Using the Flash Disk online at http://www.cisco.com/en/US/products/hw/routers/ps341/prod_installation_guide09186a00802a6394.html. PC card information is in Chapter 1 of this document.

Contents

This document contains the following chapters:

Chapter 1, "CompactFlash Disk, Flash Disk, and Flash Memory Card Information," provides information and installation instructions, as well as how to copy boot images for PC cards that insert into I/O controllers.

Chapter 2, "SDRAM and DRAM Memory Systems Overview," provides information, specifications, and configurations of SDRAM options for the network processing engine or network services engine.

Chapter 3, "Preparing for Installation," contains preparatory information for installing SDRAM memory, as well as safety warnings.

Chapter 4, "Installing and Removing SDRAM and DRAM," provides SDRAM installation and removal instructions.

Supported Platforms

The network processing engine or network services engine and the I/O controller are used in the following platforms:

Cisco 7200 series routers, which consist of the two-slot Cisco 7202, the four-slot Cisco 7204 and Cisco 7204VXR, and the six-slot Cisco 7206 and Cisco 7206VXR


Note The network services engine is supported only on the Cisco 7204VXR and Cisco 7206VXR routers.


Cisco uBR7200 series universal broadband routers, which consist of the six-slot Cisco uBR7246VXR or Cisco uBR7246 (two port adapter slots and four cable modem card slots)


Note The Cisco 7206VXR and Cisco 7206 can be used as router shelves in a Cisco AS5800 Universal Access Server. References to the Cisco 7200 VXR routers and the Cisco 7200 series routers in this document include the Cisco 7206VXR and Cisco 7206 as router shelves in a Cisco AS5800 Universal Access Server, unless indicated otherwise.
