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.

To connect a PC (or other Ethernet devices) to an Ethernet switch port, follow these steps:

1. Connect one end of the Ethernet cable to an Ethernet switch port on the router. In this example a PC is being connected to GE LAN Port 2. See Connecting a Server, PC, or Workstation.

1. 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.
2. (Optional) Connect additional servers, PCs, or workstations to the other Ethernet switch ports.

The IR829 ships with a DC power accessory kit that contains a 4-pin locking connector and pins to use for the power connections. Four contacts are supplied, but only three are used. One is a spare. The Molex power connector is Cisco part number 29-2562-01.

The power entry receptacle is on the IR829. The pin-outs are shown in Power Connector Pin-outs.

Cisco provides a power cable that can be ordered under part number IR829-DC-PWRCORD. If you choose to construct your own power cable, use special care when making the connections for DC power. It is easy to make a mistake when crimping connections, and there is a very good tutorial available at Molex: http://www.molex.com/tnotes/crimp.html

The specifications for the wiring are as follows:

• 16 AWG (1.02-to-1.29mm)
• UL1015 Rated
• Wires will be wound at 1 twist per inch

The example in Power cable shows a cable constructed with a ferrite for a different certification. You can build your cable without the ferrite eliminating items 2 and 3 in the diagram.

Details listed in the power cable example are:

To connect the DC power on your Cisco IR829, follow these steps:

1.	Identify the DC power source and measure 4 strands of copper wire 16 AWG (1.29mm) long enough to connect to the DC power source. NOTE : The maximum length of the cable before twisting is 15 feet (4.6 meters).
2.	Using an 16-gauge wire-stripping tool, strip each of the wires coming from each DC-input power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire from the power connector after installation.
3.	Using the pins included in the kit, crimp each pin onto a wire.
4.	Insert the pins into the power connector, referring to previous figures for guidance.
5.	Plug the connector into the power entry receptacle.
6.	When connecting the IR829 to a DC power source, a suitable disconnect device shall be provided at the point of connection to the DC power source.

When connecting to automotive power, it is expected that the ignition output will be +12 VDC, or +24 VDC (following the battery voltage). Connect the Ignition Input (IGN) of the router to the ignition output of the automobile. The DC In + and DC In - leads can be directly connected to the battery, but it is recommended that they be connected after a fuse.

Important

For vehicle installations, it is required to connect the Ignition Input (IGN), and use the Ignition Power Management feature of the router. This will eliminate unnecessary power cycling of the router whenever the vehicle is turned off and then turned back on.

Note	For details about the Ignition Power Management Software and setting it up, see the Cisco IR800 Integrated Services Router Software Configuration Guide .
