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

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.

Unpacking the Router

Table 1-5 lists the items that come with your router. All these items are in the accessory kit that is inside the box that your router came in.

Additional Required Equipment

Depending on your local network and which Cisco WICs and VICs you install in your router, you might need other items listed in Table 6 to complete your router installation.

Table 1-5 Router Box Contents

•

Power cord (black)

• Power supply

• DB-25 to DB-9 adapter

• Console cable, RJ-45 to DB-9 (light blue)

• Product documentation

Table 6 Additional Required Equipment

Equipment When You Use It

Ethernet hub A hub connects pieces of network equipment (including the router)

to create a network. You can use a 10-, 100-, or 10/100-Mbps hub with the router.

Ethernet switch A switch connects pieces of network equipment (including the

router) to create a network. You can use a 10-, 100-, or 10/100-Mbps switch with the router.

Phillips screwdriver Although the WICs and VICs use thumbscrews, you might need a

Phillips screwdriver to loosen the WIC and VIC cover.

Cisco WIC To make a WAN connection, the router must have a supported WIC

installed. The router supports up to two cards. You can either order the cards when ordering the router, and they will be installed for you, or you can order the cards separately, after receiving the router, and install them yourself.

Additional Required Equipment

Cisco VIC To make a voice connection, the router must have a supported VIC

installed. The router supports up to three cards. You can either order the cards when ordering the router, and they will be installed for you, or you can order the cards separately, after receiving the router, and install them yourself.

Straight-through RJ-45-to-RJ-45 cable

This cable connects the router to the Ethernet LAN and the WICs to various WAN services, including ISDN, T1/FT1, and 56-kbps services. You will need one cable for each of these connections.

Standard RJ-11 telephone cable

This cable connects the VIC to a telephone, fax machine, or a telephone wall-jack. You will need one cable for each of these connections.

Standard RJ-48 telephone cable

This cable connects the VIC to a PBX trunk line. You will need one cable for each of these connections.

Serial cable This cable connects a serial card to serial services. You must order

this cable from Cisco. For detailed information about serial cable types, refer to the Cisco WAN Interface Cards Hardware Installation Guide that comes with every card.

NT1 Some ISDN service providers require a Network Termination 1

device to connect an ISDN S/T port to the ISDN line.

Asynchronous modem To configure the router from a remote location, connect a modem to

the AUX port on the router.
