Connecting the Router

This chapter describes how to connect the Cisco 809 Integrated Services Router to Ethernet devices and a network.

Preventing Damage to the Router

Before installation, observe these general guidelines:

  • Proper ESD protection should be observed.

  • Ensure the router is properly grounded.

  • Ensure there is proper airflow around the router.

If you must supply your own cable, see the Technical Specifications for cabling specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco.


Warning

The intra-building ports of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring.These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


Warning

The intra-building ports of the equipment or subassembly must use shielded intra-building cabling/wiring that is grounded at both ends.

Connecting a Terminal or PC to the Console Port

The Cisco 809 ISR does not provide the standard Cisco RJ45 RS232 serial port for Console. Instead, a USB Console port with a mini-Type B connector is provided. 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:

Before you begin

Before you connect the router to the devices, install the router according to the instructions in Installing the Router.

Procedure

Step 1

Connect the mini-USB side of a cable to the USB Console port on the router. The following figure shows the mini-USB location (1) for the Console port on the router.

Step 2

Connect the opposite end of the mini type B USB cable to the USB port on your laptop or PC.
Step 3

To communicate with the router, wait for your laptop or PC to discover the new device.
Step 4

If your laptop or PC warns you that you do not have the proper drivers to communicate with the router, you can obtain them from your computers manufacturer, or go here: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
Step 5

Run a Terminal Emulation App (such as Tera Term) from the PC. Select the “standard” serial Com Port (from the standard or enhanced options), and configure it for 9600 Baud rate with no flow control

Wiring the DC Power and Alarm Connections

To connect the DC power and alarm connections on your Cisco 809 ISR, follow these steps:

Procedure

Step 1

Locate the power and alarm connector on the router front panel.

Note 

Your connector may not have the labels V RT A A.

In the labeled connector, the pins are:

  • V—Positive DC power connection

  • RT— Return DC power connection

  • A— Alarm Common

  • A— Alarm Input
Step 2

Identify the connector positive and return DC power connections.

The connections left to right are:

  • 1—Positive DC power connection

  • 2—Return DC power connection

  • 3—Alarm Common

  • 4—Alarm Input
Step 3

Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to connect to the DC power source.
Step 4

Using an 18-gauge wire-stripping tool, strip each of the two twisted pair 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.

Step 5

Remove the two captive screws that attach the power and alarm connector to the router, and remove the connector.
Step 6

On the power and alarm connector, insert the exposed part of the positive wire into the connection labeled "V" and the exposed part of the return wire into the connection labeled "RT". Make sure that you cannot see any wire lead. Only wire with insulation should extend from the connector.

1—Power connector captive screws

Note 

Use the same method for wiring the alarm connections.
Step 7

Use a ratcheting torque flathead screwdriver to torque the power connector captive screws (above the installed wire leads) to 2 in-lb (0.23 N-m).

Step 8

Connect the other end of the positive wire to the positive terminal on the DC power source, and connect the other end of the return wire to the return terminal on the DC power source. Connect the other end of the Alarm wires to your alarm source.

Connecting the Router to the AC-Input Power Supply

A 50 W AC-input power supply is available as an option for the router. The power supply comes in two styles:

  • PWR-IE50W-AC—An AC-input power supply with a terminal block connector for the source AC cable.

  • PWR-IE50W-AC-IEC— An AC-input power supply with an IEC C14 appliance connector for adetachable AC power cord.

The figure below shows the AC-input power supply.

Note 

The source AC terminal block shown in the illustration is replaced by an IEC C14 appliance connector on the PWR-50W-AC-IEC= power supply.

Connecting the Router to the DC Source.

To connect the IR809 to the DC output, you will need to use a length of twisted pair along with connectors on both ends. The twisted pair should be sized to handle at least 1 Amp at 24VDC. Details on the connector and pin-outs for the IR809 side are found earlier in this guide at Wiring the DC Power and Alarm Connections. The PWR-IE50W-AC power source comes with a DC clip that can be reused to connect to the IR809. Disassemble the DC clip to expose the 2 pin and 4 pin connectors, as shown in the following diagram.

Dispose of the cover and the wire in the pre-assembled cable clip, but keep the 2-pin connector for the power supply side, and the 4-pin connector for the IR809 side.


Note
The IR809 should already have this 4-pin connector included, but if not, the one in the clip can be used.

Measure an appropriate length of wire for your installation and wire the 2 pin connector back onto the PWR-IE50W-AC power source DC output as it was. Wire the opposite end of the wire to the IR809 4 pin connector as instructed previously in the Wiring the DC Power and Alarm Connections section. Your finished cabling will look like the connectors and wiring in the bottom of the following figure:

The connections should match up as in the following table:

Connecting the Power Converter to an AC Power Source

The following instructions are provided for a qualified electrician to attach the AC power cord to the power supply.


Caution
AC power sources must be dedicated AC branch circuits. Each branch circuit must be protected by a dedicated two-pole circuit breaker.

Caution
Do not insert the power cord into the AC outlet until the process of wiring the line, neutral, and ground connections has been completed.

To connect the AC power cord to the power converter, follow these steps:

Before you begin

To connect the power converter to an AC power source, you need an AC power cord. Power cord connector types and standards vary by country. Power-cord wiring color codes also vary by country. You must to have a qualified electrician select, prepare, and install the appropriate power cord to the power supply.


Note
Use copper conductors only, rated at a minimum temperature of 167°F (75°C).

Procedure

Step 1

Remove the plastic cover from the input power terminals and set it aside.
