This chapter describes the equipment and procedures necessary for successfully installing the Cisco IRM-1100-4A2T Expansion Module onto the IR1101.
For details on the expansion module, see Cisco IRM-1100-4A2T Expansion Module section.
Unpack the box and verify that all items listed on the invoice were shipped with the Cisco IRM-1100-4A2T.
The following items are shipped with your Expansion Module:
Four mating screws to connect the IRM-1100-4A2T to the IR1101
This section describes how to install the Cisco IRM-1100-4A2T on the EM (top) side of the router. The Expansion Module attaches to the IR1101 Base using 4 mating screws, and is connected through a mating connector. The Expansion Module is grounded and powered through the connection to the IR1101.
To attach the IRM-1100-4A2T to the IR1101 on the EM side, perform the following steps:
|
Step 1 |
Remove the protective cover from the mating connector on the IR1101 by unscrewing the two Phillips head screws. Refer to the following figure. 
|
||||||
|
Step 2 |
After removing the protective connector cover from the IR1101, carefully align the Expansion Module to the IR1101 so that both mating connectors engage. Refer to the following figure. Once properly seated, install the four mating screws to fully secure the Expansion Module to the IR1101. 
|
||||||
|
Step 3 |
Tighten the screws to a torque of 13-15 in. lbs (1.5-1.7 newton meter). When complete, the two devices form a single assembly as shown in the following figure. 
|
This section describes how to install the Cisco IRM-1100-4A2T on the CM (bottom) side of the router. The Expansion Module attaches to the IR1101 Base using 4 mating screws, and is connected through a mating connector. The Expansion Module is grounded and powered through the connection to the IR1101.
To attach the IRM-1100-4A2T to the IR1101 on the CM side, perform the following steps:
|
Step 1 |
Remove the protective cover from the mating connector on the IR1101 by unscrewing the two Phillips head screws. Refer to the following figure. 
|
||||
|
Step 2 |
After removing the protective connector cover from the IR1101, rotate the expansion module upside down so the mating connector is facing the IR1101 base unit. Carefully align the Expansion Module to the IR1101 so that both mating connectors engage. Refer to the following figure. Once properly seated, install the four mating screws to fully secure the Expansion Module to the IR1101. 
|
||||
|
Step 3 |
Tighten the screws to a torque of 13-15 in. lbs (1.5-1.7 newton meter). When complete, the two devices form a single assembly as shown in the following figure. 
|
After the Cisco IRM-1100-4A2T is attached to the IR1101, it can be mounted in the following ways:
On a DIN Rail
Using mounting brackets
 Note |
For the remainder of these instructions, we will refer to the combined IR1101/IRM-1100-4A2T as the “Device”. |
The wall mounting kit part number is IR1101-WALLMNT and contains the following:
Mounting brackets (x2)
Mounting screws (x4)
 Warning |
Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system. Statement 378 |
 Tip |
When choosing a location for wall-mounting the Device, consider cable limitations and wall structure. |
Note |
A minimum of 1 inch clearance is required on all sides of the device except for the side mounted against the wall/floor or DIN rail, to allow for proper air flow. |
The Device can be mounted on the top of a flat surface as shown in the following figure, but cannot be mounted upside down.
The device can also be mounted vertically on a wall in four orientations as shown in the following figure.
To mount the Device on a wall or other flat surface, follow these steps:
|
Step 1 |
Attach the mounting brackets to the bottom of the Device. Refer to the following figure for guidance. 
|
||||||
|
Step 2 |
Align the mounting brackets over the mounting holes so that the larger holes on the brackets extend out over the Device. |
||||||
|
Step 3 |
Attach the brackets to the Device with the four screws provided using a Phillips head driver. Torque to 13-15 in. lbs (1.5-1.7 newton meter). |
||||||
|
Step 4 |
Mount the Device with the attached brackets in a proper wall structure to carry the weight of the device, which is a combined 3.85 lbs. See the following figures for the dimensions of the mounting holes with the brackets attached to the Device. 
|
||||||
|
Step 5 |
Route the cables so that they do not put a strain on the connectors or mounting hardware. |
The DIN Rail kit is ordered separately, and the part number is IRM-1100-DINRAIL. The Device can only be mounted vertically, with the ground lug on the bottom side as shown in the following figures.
|
Step 1 |
Attach the DIN rail brackets to the back of the Device. There are two separate mounting brackets. One attaches to the IR1101, and the other attaches to the IRM-1100-4A2T. The combined DIN rail brackets mount in the vertical orientation only. See the following figure. 
|
||||||||
|
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-DINRAIL 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. |
To attach the Device with the brackets to a DIN rail, follow these steps. Refer to the following figure for details of a completed attachment.
|
1 |
DIN rail clips |
|
2 |
DIN rail |
|
Step 1 |
Position the router so that the lower edge and spring of the DIN clip, located within the bottom of the DIN rail bracket, engages with the bottom section of the DIN rail. Push up to compress the spring.
|
||
|
Step 2 |
Rotate the router so that the top hook of the DIN clip clamps to the top section of DIN rail. Refer to the following figures.
|
||
|
Step 3 |
To remove the Device from the DIN Rail, simply reverse the procedure.
|
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.
