Cable Connection Procedures for Cisco 1805 DOCSIS Cable Router


This chapter describes how to connect your Cisco 1805 DOCSIS cable router to a power source and to networks and external devices. It includes the following sections:

Power Connections

Connecting WAN and LAN Cables

Connecting to a Console Terminal or Modem

For cable information and specifications, see the "Cable Information and Specifications for Cisco 1805 DOCSIS Cable Routers" chapter.


Note Before you install, operate, or service the system, read the Regulatory Compliance and Safety Information for Cisco 1840 Routers for important safety information and translations of the warnings that appear in this guide.


Power Connections


Warning Read the installation instructions before connecting the system to the power source. Statement 1004.



Note The installation must comply with all required electrical codes applicable at the installation site.


Connect your router to a 15A, 120 VAC (10A, 240 VAC) circuit with overcurrent protection.


Note The input voltage tolerance limits for AC power are 85 and 264 VAC.



Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 15A, 120VAC (10A, 240VAC). Statement 1005


Connecting WAN and LAN Cables

This section describes how to connect the WAN and LAN interface cables. It covers the following topics:

Ports and Cabling

Connection Procedures and Precautions


Note One or two Ethernet cables are typically provided with the router. You can order additional network connection cables and transceivers from Cisco. For ordering information, contact Cisco customer service. For cable pinouts, see the Cisco Modular Access Router Cable Specifications document, which is available online.



Warning Do not work on the system, or connect or disconnect cables during periods of lightning activity. Statement 1001

Connection Procedures and Precautions

Connect each WAN and LAN cable to the appropriate connector on the chassis or interface card.

Position the cables carefully, so that they do not put strain on the connectors.

Organize the cables in bundles so that cables do not intertwine.

Inspect the cables to make sure that the routing and bend radius are satisfactory. Reposition the cables, if necessary.

Install cable ties in accordance with your site requirements.

For cable pinouts, see the Cisco Modular Access Router Cable Specifications document.

Connecting to a Console Terminal or Modem

Your router has asynchronous serial console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

Cisco provides the following cables and adapters for connecting your router to a console terminal, PC, or modem:

One console cable (RJ-45-to-DB-9, blue)

One modem adapter (DB-9-to-DB-25)

This section describes how to connect a console terminal or PC to the console port and how to connect a modem to the auxiliary port.

For information about cable pinouts, see the Cisco Modular Access Router Cable Specifications.

Connecting to the Console Port

To configure the router through the Cisco IOS command-line interface (CLI), you must connect the router console port to a terminal or PC. The cable required for this connection is included with the router.

The PC must have HyperTerminal or similar terminal emulation software installed. The software should be configured with the following parameters: 9600 baud, 8 data bits, no parity, 1 stop bit, and no mode control. See the Cisco 1800 series router software configuration documents for detailed information about using Cisco IOS software for configuring the router.

To connect the router to a terminal or PC, follow these steps:


Step 1 Connect the end of the light blue console cable with the RJ-45 connector to the light blue console port on the router. (See Figure 5-1.)

Step 2 Connect the end of the cable with the DB-9 connector to the terminal or PC. If your terminal or PC has a console port that does not accommodate a DB-9 connector, you must provide an appropriate adapter for that port. (A DB-9-to-DB-25 adapter is provided with your router.)



Note Because mode control is not possible on the console port, we do not recommend connecting modems to the console port. Modems should always be connected to the auxiliary port.


Connecting to the Auxiliary Port

When a modem is connected to the auxiliary port, a remote user can dial in to the router and configure it. Use the light blue console cable and the DB-9-to-DB-25 connector adapter that came in the router accessory kit.

To connect a modem to the router, follow these steps:


Step 1 Connect the RJ-45 end of the adapter cable to the black AUX port on the router. (See Figure 5-2.)

Step 2 Connect the DB-9 end of the console cable to the DB-9 end of the modem adapter.

Step 3 Connect the DB-25 end of the modem adapter to the modem.

Step 4 Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115200 bps is supported) and for mode control with data carrier detect (DCD) and data terminal ready (DTR) operations.
