Note For compliance and safety information, see the Regulatory Compliance and Safety Information Roadmap that ships with the router and Regulatory Compliance and Safety Information for Cisco 800 Series and SOHO Series Routers.
Preparing to Connect the Router
Before you connect the router to the devices, install the router according to the instructions in the "Installing the Router" section.
Preventing Damage to the Router
To prevent damage to your router, follow these guidelines when connecting devices to your router:
•Turn off power to the devices and to the router until all connections are completed.
Caution Do not turn on the devices until after you have completed all connections to the router.
•If you must supply your own cable, see the "Technical Specifications" section for cabling specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco.
Connecting a PC, Server, or Workstation
To connect a PC (or other Ethernet devices) to an Ethernet switch port, follow these steps:
Step 1 Connect one end of the yellow Ethernet cable to an Ethernet switch port on the router. See Figure 3-1.

Step 2 Connect the other end of the cable to the RJ-45 port on the network interface card (NIC) that is installed in the PC, server, or workstation.
Step 3 (Optional) Connect additional servers, PCs, or workstations to the other Ethernet switch ports.
Note Use the Cisco Configuration Express to configure the Internet connection settings. See Cisco Configuration Professional Quick Start Guide for more information.
Connecting an External Ethernet Switch
If more than four PCs in an office must be connected to each other, you can add Ethernet connections to the router by connecting an external Ethernet switch to the Ethernet switch on the router.
To connect an external Ethernet switch to an Ethernet switch port on the router, complete the following steps:
Step 1 Connect one end of the yellow Ethernet cable to an Ethernet switch port on the router. (See Figure 3-2.)

Step 2 Connect the other end of the cable to the available port on the Ethernet switch to add additional Ethernet connections.
Step 3 Turn on the Ethernet switch.
Connecting a Terminal or PC to the Console Port
Connect a terminal or PC to the Console port either to configure the software by using the CLI or to troubleshoot problems with the router.
To connect a terminal or PC to the console port on the router and access the CLI, follow these steps:
Step 1 Connect the RJ-45 end of a DB-9-to-RJ-45 serial cable to the RJ-45 Console port on the router. Figure 3-3 shows the RJ-45 end of the serial cable connected to the Console port on the router.

Step 2 Connect the DB-9 end of the DB-9-to-RJ-45 serial cable to the COM port on your laptop or PC.
Note Some laptops and PCs do not come with DB-9 serial port connectors and may require a USB-to-serial port adapter.
Step 3 To communicate with the router, start a terminal emulator application.
Terminal Emulator Settings
Use the following settings for the terminal emulator connection:
•9600 baud
•8 data bits, no parity
•1 stop bit
•No flow control
When the terminal emulator establishes communications, the router prompt is displayed.
For more information on terminal emulation settings, see Applying Correct Terminal Emulator Settings for Console Connections.
Connecting a Modem to the Console Port
To connect a modem to the router, follow these steps:
Step 1 Connect the RJ-45 end of the adapter cable to the Console port on the router as shown in Figure 3-4.
Figure 3-4 Connecting a Modem to the Console Port
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 console port are configured for the same transmission speed (up to 115200 b/s is supported) and support mode control with data carrier detect (DCD) and data terminal ready (DTR).
Connecting the AC Adapter

|
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 120VAC, 20A U.S (240VAC, 16 to 20A international). Statement 1005
|
|
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045

To connect your Cisco 819 ISR to an AC power outlet, follow these steps:
Step 1 Connect the AC adapter to an AC power outlet.
Step 2 Plug the adapter cord into the router.
Connecting the DC Adapter

To connect the DC power on your Cisco 819 ISR, follow these steps:
Step 1 Connect the black and white lead wires to a 12 VDC source. The black lead is negative or ground and the white lead is positive. The output cable is 1.3 meters while the input cable is 1 meter in length. (See Figure 3-5 and Figure 3-6.). For the complete list of supported power adapters, see the "Supported Power Adapters" section.
