Step 2

Attach the IR1101 DIN mounting bracket to the Device using the two screws provided in the kit. Position the bracket over the two mounting holes, then use 13-15 in. lbs. (1.5-1.7 newton meter) of torque to screw the bracket onto the Device.

Step 3

Attach the IRM-1100 DIN mounting bracket to the Device using the screw provided in the kit. Position the bracket over the single mounting hole, then use 13-15 in. lbs. (1.5-1.7 newton meter) of torque to screw the bracket onto the Device.

Step 4

Once the two brackets are attached to the Device, it can be mounted onto the DIN Rail.

Attaching the Bracket onto the DIN Rail

To attach the Device with the brackets to a DIN rail, follow these steps. Refer to the following figure for details.

Figure 11. Attaching the Brackets to the DIN Rail

Procedure

Step 1

Position the Device so that the lower edge and spring of the Din clips (1 ) engages with the bottom section of the Din rail (2 ).

Step 2

Push up on the Device so that the spring of DIN clips (1 ) compresses against the lower section of DIN rail (2 ) and then rotate the Device so that the top hook of the DIN clips (1 ) clamps to the top section of DIN rail (2 ).

Step 3

To remove the Device from the DIN Rail, simply reverse the procedure.

Note

 
In order to prevent excessive side to side movement of the unit it is advised to install DIN rail stop plates such as Mouser part Numbers 653-PFP-M, 651-1201662 or 845-CA402. These stop plates can be installed on one or both sides of the unit to limit excessive side to side movement that typically occurs in high vibration environments.

Step 4

If you are using this Device in a vehicle, attach the ring terminal to the chassis using one of the screws provided and the green or green and yellow striped wire. Connect the other end of the wire to the vehicle ground.

What to do next

After you install and properly ground the Device, you can connect the power wiring, the LAN cables, and the cables for administrative access as required for your installation.

Pluggable Module

The Pluggable Module provides the IRM-1100 with a number of different configuration options. The installation of the Pluggable Module into the Expansion Module is the same as installing it into the IR1101. See that section at Cisco Pluggable Modules.

Digital I/O Connections

The wired Digital I/O connector is show as (1 ) in the following figure.

Figure 12. Digital I/O connector

The Digital I/O connector has 4 GPIO connections plus 1 Return connection. The default state of the Digital I/O is input, the open-collector is open (off). Further details on the Digital I/O connector can be found at Digital I/O Connector.

Wiring the Alarm Connections

To wire the alarm connections on your Cisco IR1101 Expansion Module, follow these steps:

Procedure

Step 1

Locate the alarm connector on the router front panel.

Step 2

Identify the connectors.

Step 3

Using a wire-stripping tool, strip each of the alarm wires 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 connector after installation.

Step 4

Remove the two captive screws that attach the alarm connector to the Expansion Module, and remove the connector

Step 5

On the alarm connector, insert the exposed part of the wire into the connection. Make sure that you cannot see any wire lead. Only wire with insulation should extend from the connector. See the following figure.
