Key Features

The Cisco 1750 router is a voice-and-data capable router that provides

Voice-over-IP functionality (VoIP) and can carry voice traffic (for example,

telephone calls and faxes) over an IP network. Using one to four WAN

connections, the router links small-to-medium-size remote Ethernet and

FastEthernet LANs to central offices. Table 1 lists the router key features.

Router Memory

This section describes the types of memory stored in the router and how to find

out how much of each the router has.

For instructions on how to upgrade memory in the router, refer to the “Installing

and Upgrading Memory and Data Modules” appendix in this guide.

Types of Memory

The router has the following types of memory:

•Dynamic RAM (DRAM)—This is the main storage memory for the router.

DRAM is also called working storage and contains the dynamic configuration

information. The router stores a working copy of Cisco IOS software,

dynamic configuration information, and routing table information in DRAM.

•Nonvolatile RAM (NVRAM)—This type of memory contains the startup

configuration.

•Flash memory—This special kind of erasable, programmable memory

contains a copy of the Cisco IOS software. The Flash memory structure can

store multiple copies of the Cisco IOS software. You can load a new level of

the operating system in every router in your network and then, when

convenient, upgrade the whole network to the new level. The Flash memory

on the router is stored on mini-Flash modules.

Router Memory

Cisco 1750 Router Hardware Installation Guide

78-6169-02

Amounts of Memory

Use the show version command to view the amount of DRAM, NVRAM, and

Flash memory stored in your router. The following example shows the output of

the show version command. The bold text displays the amount of memory stored

in this router.
