Cisco 1000 ISR Series Guide

Install and Connect the Router
This chapter describes how to install and connect Cisco 1000 Series Integrated Services Router (ISR) to LAN
and WAN networks.
Read the installation instructions before using, installing or connecting the system to the power source.
Statement 1004
Warning
Installing the Cisco 1000 Series Integrated Services Routers involve these tasks:
•Unpack the Router, on page 1
•Set up Router on Desktop, Rack, or Wall, on page 1
•Connect Power Cable, on page 19
•Connect the Router to a Console, on page 21
•Connect WAN and LAN Interfaces, on page 25
•Configure the Router at Startup, on page 26
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.

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.

If you choose to setup the router on a desktop, you can place the router on a desktop, bench top or on a 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.
Do not stack multiple Cisco 1000 ISRs when mounting the routers on a table top.

Rack Mount

When mounting Cisco 1000 ISRs on a rack, ensure that there is ample surrounding space. This ensures more
heat removal, which in turn will enable the surrounding air temperature to stay within the specified operating
conditions.
Note
Attach the Brackets for C111x
This procedure describes how to attach the brackets on the router chassis:
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.
Attach the Rack Mounting Brackets for C112x
This procedure describes how to attach the brackets on the router chassis:
Step 1 Remove the 6 screws from the bottom of the chassis.
Step 2 Place the platform into the bottom tray.
Step 3 Secure the original screws from the bottom side of the tray.

Mount the Router
Before mounting the router on to the rack, refer to the following safety warning statements:
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
PurposeCommand or Action
To install the router, use the screws provided with the
accessory kit to secure the router when you mount it on the
rack.
Step 1
Mount the Router under a Desk or a Shelf
Installing the router under a desk requires an optional bracket kit that is not included with the router. The kit
contains the rack-mount brackets and screws to secure the brackets to the router and the underside of the desk.
You can order these kits from your Cisco representative. This procedure describes how to mount router under
a desk or a shelf .
Step 1 Attach a bracket to one side of the router using the flat-head screws. Follow the same steps to attach the second bracket
to the opposite side.

Mount Router using DIN Rail Brackets
The router is shipped with DIN Rail brackets that are to be secured on the bottom side of the chassis. Your
chassis installation must allow unrestricted airflow for chassis cooling.

Mount Router using DIN Rail Brackets

To attach the DIN Rail brackets to the router chassis, use the PHMS screws and the plastic spacers provided for each
bracket.
Attach Din-Rail Brackets on C112x
This procedure describes how to attach the brackets on the router chassis:
Step 1 Remove the 3 bottom screws from the chassis.
Step 2 Place the din-rail tray assy on the bottom side of the chassis.
Step 3 Secure the original screw from bottom side of tray, leverage the existing chassis screws to secure the din rail mounting
bracket from the bottom of the chassis.
Step 4 Take the other two screws to secure the din-rail trail assy

Wall Mount the Router
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.
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.
Warning
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.
Note
There are two ways to mount a router on the wall, using 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.
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.
