Router Memory

This section describes the types of memory stored in the router and how to find out how much of each type of memory is stored in the router.

For instruction on how to upgrade memory in the router, refer to the "Installing and Upgrading Router Memory" appendix later in this guide.

Types of Memory

The Cisco 1700 router has the following types of memory:

Dynamic random-access memory (DRAM)---This i s the main storage memory for the router. DRAM is also called working storage and contains the dynamic configuration information. The Cisco 1700 router stores a working copy of Cisco IOS software, dynamic configuration information, and routing table information in DRAM.
Nonvolatile random-access memory (NVRAM)---This type of memory contains a ba ckup copy of your configuration. If the power is lost or the router is turned off, this backup copy enables the router to return to operation without reconfiguration.
Flash memory---T his 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 Cisco 1700 router is stored on mini-Flash modules.

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 of the show version command output in bold text displays the amount of memory stored in this router.

Unpacking the Router

Figure 1-4 shows the items that come with your router. All of these are in the accessory kit that is inside the box that your router came in.

Figure 1-4: Router Box Contents

Additional Required Equipment

Depending on your local network and which Cisco WAN interface cards you install in your router, you will require other items, listed in Table 1-5, to complete your router installation.

Table 1-5: Additional Required Equipment

Equipment When You Use It

Ethernet hub

A hub connects pieces of network equipment (including the Cisco 1700 router) to create a network. You can use a 10-, 100-, or 10/100-Mbps hub with the Cisco 1700 router.

Ethernet switch

A switch connects pieces of network equipment (including the Cisco 1700 router) to create a network. You can use a 10-, 100-, or 10/100-Mbps switch with the Cisco 1700 router.

Phillips screwdriver

Although the WAN interface cards use thumbscrews, you might need a Phillips screwdriver to loosen the WAN interface card slot cover.

Cisco WAN interface card

In order to make a WAN connection, the Cisco 1700 router must have a supported WAN interface card installed. The router supports up to two cards. You can order the cards when ordering the router, and they will be installed for you. 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 WAN interface cards to various WAN services, including ISDN, T1/FT1, and 56-kbps services. You will need one cable for each connection that requires this cable type.

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

Connect a modem to the AUX port on the router when you want to configure the router from a remote location.
