Key Features Cisco 1700 Router 12154 Figure 1-1 PWR WIC0 ACT/C WI H0 AC C1 T/CH0 ETH ACT OK ACT/C H1 AC T/C H1 COL Cisco 1700 SER IES RO UT ER Key Features The Cisco 1700 router is a small, modular desktop router that links small- to medium-size remote Ethernet and FastEthernet LANs over one to four WAN connections to regional and central offices. Table 1-1 lists the router key features.
Key Features Table 1-1 Key Features Feature Description One FastEthernet (10/100BaseTX) port • Operates in full- or half-duplex mode (with manual override available). • Supports autosensing for 10- or 100-Mbps operation. Two Cisco WAN interface card slots • Supports a combination of any two of the following WAN interface cards: ISDN BRI, 56-kbps DSU/CSU, FT1/T1 DSU/CSU, high-speed serial, and dual-serial. • The WAN interface configuration can be changed as your network requirements change.
Rear-Panel Ports and LEDs Rear-Panel Ports and LEDs This section describes the router rear panel ports and LEDs, which are shown in Figure 1-2 and described in Table 1-2 and Table 1-3.
Rear-Panel Ports and LEDs Table 1-2 Rear-Panel Connectors (Continued) Connector/Slot Label/Color Description WAN interface card slot (WIC1) No label Supports one Cisco WAN interface card. For detailed information, refer to the Cisco WAN Interface Cards Hardware Installation Guide that comes with every card. Power socket +5, +12, -12 VDC Connects the router to the external power supply.
Front-Panel LEDs Front-Panel LEDs Use the router front-panel LEDs to determine network activity and status on the Ethernet port and on the WAN interface card ports. The front-panel LEDs are illustrated in Figure 1-3 and described in Table 1-4.

WICØ ACT/CHØ ISDN cards—On solid when the first ISDN B channel is up for the card in the WICØ slot. 2-port serial cards—Blinks when there is data being sent to or received from the first port on the 2-port card in the WICØ slot. ACT/CH1 Green Serial and CSU/DSU cards—Remains off.
Router Memory 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: 1-8 • Dynamic random-access memory (DRAM)—This is the main storage memory for the router.
Amounts of 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 of the show version command output in bold text displays the amount of memory stored in this router. 1700# show version Cisco Internetwork Operating System Software IOS (tm) C1700 Software (C1700-Y-M), Version 12.X(XX)T [cisco-ferrari2 121] Copyright (c) 1986-1998 by cisco Systems, Inc.

Unpacking the 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.
Additional Required Equipment 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.
