Install and Connect the Router

This chapter describes how to install and connect Cisco 1100 Series Integrated Services Router (ISR) to LAN and WAN networks.


Warning

Read the installation instructions before using, installing or connecting the system to the power source. Statement 1004

Installing the Cisco 1100 Series Aggregation Services Routers involve these tasks:

Unpack the Router

Unpack the router only when you are ready to install it. If the installation site is not ready, to prevent accidental damage, keep the chassis in its shipping container until you are ready to install.

The router, accessory kit, publications, and any optional equipment you order may be shipped in more than one container. When you unpack the containers, check the packing list to ensure that you have received all listed items.

Set up Router on Desktop, Rack, or Wall

After unpacking, based on your requirements, you can set up a Cisco 1100 Series Integrated Services Routers (ISRs) on a desktop, a rack, or the wall.


Note

You can install external modules before or after mounting a router. However, if you choose to install the external modules after mounting the router on the rack or wall, ensure that you have optimal access to the back/front panel of the router.

For information on modules and Field Replaceable Units (FRUs), see the Install and Upgrade Modules and FRUs section.

Depending on the model, the available options for mounting a Cisco 1100 ISR are:

If you choose to setup the router on a desktop, you can place the router on a desktop, bench top, or shelf.

Rack Mount

The router is shipped with rack mounting brackets that are to be secured on the sides of the chassis. You must first secure rack mounting brackets on the chassis before you set up the chassis on the rack.


Note

When stacking multiple Cisco 1100 ISRs, ensure that there is ample surrounding space. Ample space, in turn, ensures more heat removal to enable the surrounding air temperature to stay within the specified operating conditions.

Attach the Brackets

This procedure describes how to attach the brackets on the router chassis:

Procedure
Step 1

Secure the brackets to the router chassis (on the left) as shown in figure below:

Example:
Figure 1. Bracket Installation for Left-Side Mounting - C111x
Step 2

Similarly, secure the brackets on the right-side of the chassis for mounting the router.

Mount the Router

Before mounting the router on to the rack, refer to the following safety warning statements:


Warning

To prevent airflow restriction, allow clearance around the ventilation openings to be at least: 1.75 in. (4.4 cm). Statement 1076.


Warning

  • To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

  • This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

  • When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006.

Procedure

To install the router, use the screws provided with the accessory kit to secure the router when you mount it on the rack.

Wall Mount

Depending on the models of the Cisco 1100 Series Integrated Services Routers (ISRs), the tasks for mounting the router chassis on the wall may vary.


Note

The recommended clearance when a router is horizontally mounted is 1.5 inches on both sides for clearance and 1.75 inches on top. I/O side clearance is needed as it is required to access the cable connections. Clearance is not required on the backside (opposite side from I/O face) unless mounting on a DIN Rail. Clearance is required to attach and mount the DIN rail bracket.

There are two ways to mount a router on the wall-Key-hole Slots and DIN Rail Brackets.

Wall Mount Using Key-hole Slots

The Cisco 1100 Series Integrated Services Routers (ISRs) have key-hole slots at the bottom of the chassis for mounting on a wall or any vertical surface.


Note

Do not mount the router with the output ports facing downwards. For the C111x series, ensure that the cables are placed on the sides.


Note

When choosing a location for wall mounting the router, consider cable limitations and wall structure.

Note

To attach a router to the wall stud, each bracket should have one number10 wood screw (pan-head) with number10 washers, or two number10 washer-head screws. The screws must be long enough to penetrate at least 1.5 inches (38.1 mm) into the supporting wood or metal wall stud.


Note

For hollow-wall mounting, each bracket requires two wall anchors with washers. Wall anchors and washers must be size number 6 (pan-head). Route the cables so that they do not put a strain on the connectors or mounting hardware.

Do not over-torque the screws. The recommended torque is 8 to 10 inch-lbf (0.9 to 1.1 N-m).

Chassis Grounding

After you set up the router, connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards. For safety information on grounding the chassis, refer to the chassis ground connection procedures.

  1. For grounding the chassis, use size 14 AWG copper wire and the ground lug. These are not a part of the accessory kit.

  2. Use the UNC 6-32 screws, which have a length of about 0.25 inches.

To install the ground connection for your router, perform these steps:

  1. Strip one end of the ground wire to the length required for the ground lug or terminal.

    • For the ground lug—approximately 0.75 inch (20 mm)

    • For user-provided ring terminal—as required

  2. Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.

  3. Attach the ground lug or ring terminal to the chassis as shown in Figure. The screw for the ground lug is provided. Tighten the screw; the recommended torque is 8 to 10 inch-lbf (0.9 to 1.1 N-m).
