3 Parts List
Your router package should include the following items:
•One Cisco 1700 series router
•One blue RJ-45-to-DB-9 console cable
•One black power supply
•One black power supply cord
Items You Need to Provide
Depending on your network environment, you must provide some of the following items to completely install the router:
•Ethernet hub or switch to connect the router to the local network
•Straight-through Ethernet cable (RJ-45-to-RJ-45) to connect the router to the hub or switch
•Cisco WAN interface card if you did not order the router with cards already installed
•Cables to connect WAN interface cards to the appropriate WAN services
•External NT-1 or DSU/CSU if needed to connect a WAN interface card to WAN services
4 Install the Router
Follow these steps to install the router.
Connect the Router to the Local Network
You need to provide a straight-through Ethernet cable for connecting the router to the local Ethernet network. For more information on these cables, refer to the "Cabling Specifications" chapter in the hardware installation guide that came with the router.
Step 1 Connect one end of the Ethernet cable to the yellow 10/100 ETHERNET port.
Figure 1 Installing the Router
Step 2 Connect the other end to a 10-, 100-, or 10/100-Mbps port on the hub or switch. The router senses the port speed and duplex mode and then operates at the same speed and duplex.
Caution Always connect the Ethernet cable to the yellow ports on the router. Do not connect the cable to an ISDN S/T or U port (on a WAN interface card) or to an NT1 that is connected to a WAN interface card. Accidently connecting the cable to the wrong port can damage your router.
Install the WAN Interface Card(s)
Look for a WAN interface card in one or both of the two slots on the rear of the router. If a card is already installed, connect it to the WAN line according to the <Emphasis>Cisco WAN Interface Cards Hardware Installation Guide that came with the card. To install a card in either slot, follow these instructions:
Step 1 Set the power switch to the STANDBY ( ) position and confirm the router is not connected to the power supply.
Step 2 Remove the screws that hold the slot cover in place, and then remove the slot cover.
Figure 2 Locating the WAN Interface Card
Step 3 Hold the card by the edges and line it up with the guide on the card slot.
Step 4 Push the card into the slot until it is seated in the connector and the front panel is flush with the router rear panel.
Figure 3 Installing the WAN Interface Card
Step 5 Tighten the screws that are in the card.
Step 6 Connect the card port to the WAN line according to the <Emphasis>Cisco WAN Interface Cards Hardware Installation Guide.
Connect a PC to the Router
To use Cisco IOS software to configure the router, it must be connected to a terminal or to a PC with terminal-emulation software. Terminal emulation software should be configured with the following settings: 9600 baud, 8 data bits, no parity bits, and 1 stop bit. The Cisco 1700 Router Software Configuration Guide describes how to configure the router using Cisco IOS software.
Take the following steps to connect the router to one of these devices:
Step 1 Connect one end of the blue console cable (included) to the CONSOLE port on the router rear panel.
Step 2 Connect the RJ-45 end of the gray DB-9-to-RJ-45 adapter (included) to the unconnected end of the console cable.
Figure 4 Connecting a PC to the Router
Step 3 Connect the DB-9 end of the adapter to the console port (also called the serial port) on your PC. If this adapter does not fit your PC console port, you must provide an adapter that fits.
Connect the Power Supply
Connect the router to the power supply as shown below.
Step 1 Connect the attached power-supply cord to the power socket (labeled +5, +12, -12 VDC) on the router rear panel.
Step 2 Connect the separate power cord to the power socket on the power supply.
Step 3 Connect the other end of the separate power cord to a power outlet.
Step 4 Turn on the router by pressing the power switch to the ON ( | ) position.
Figure 5 Connecting the Power Supply
Step 5 Confirm that the router has power by checking that the PWR LED on the front panel is on.
5 Verify Your Installation
After the router is powered on, the following LEDs confirm that you have correctly installed your router.

10 Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.
Cisco Technical Support Website
The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:
Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:
Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
