Installing the Router
This chapter describes how to install your Cisco 3600 series router and lists other documents you can refer to for instructions on connecting the router to networks and external devices. Depending on your router model, you have the following installation options:
- Cisco 3620 and Cisco 3640 routers can be installed on a desktop, in a rack, or on a wall or other flat surface.
- Cisco 3660 routers can be installed on a desktop or in a rack.
Use the procedure in this chapter to install your router in a rack. For information on installing a Cisco 3600 series router on a desktop or wall, see the publication Cisco 3600 Series Hardware Installation Guide.
This chapter contains the following sections:
 | Warning
Only trained and qualified personnel should be allowed to install or replace this equipment. |
You can mount the Cisco 3620 and Cisco 3640 routers in a 19-inch rack (with a 17.5- or 17.75-inch opening), or a 23- or 24-inch rack.
The Cisco 3660 router can be mounted in a 19-inch rack (with a 17.5- or 17.75-inch opening) or a 23-inch rack.
The following information will help you plan your equipment rack configuration:
- Allow clearance around the rack for maintenance.
- Enclosed racks must have adequate ventilation. Make sure that the rack is not congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.
- When mounting a device in an open rack, make sure that the rack frame does not block the intake or exhaust ports. If the device is installed on slides, check its position when it is seated into the rack.
- Baffles can isolate exhaust air from intake air, and also help to draw cooling air through the device. The best placement of the baffles depends on airflow patterns in the rack, which you can find by experimenting with different configurations.
- If equipment installed in a rack (particularly an enclosed rack) fails, try operating the equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power.
To rack-mount a Cisco 3600 series router, you need the following tools and equipment (which are not included):
- Cisco 3600 series router
- Equipment rack
- Number 2 Phillips screwdriver
- ESD-preventive wrist strap
- Screws for attaching the router to the rack
You need these additional tools and equipment to install a grounding lug on a Cisco 3600 series router:
- Insulated 6-AWG grounding wire, long enough to reach from the router to your grounding point
- Wire stripping tool
- Crimping tool large enough for the wire receptacle on the grounding lug
You need this additional item to install an alarm terminal block on a Cisco 3660 router:
- Insulated 12- or 14-AWG copper wire to connect the alarm port terminals to a central office alarm system
Before you mount the router, make sure that power is OFF. Remove the power cable and all network interface cables, including telephone cables, from the rear panel.
The following warning applies to routers that use a DC power supply:
If you need to install network modules or WAN interface cards, you can do so either before or after mounting the router, whenever you have better access to the rear panel of the router. For instructions, refer to the following publications: Cisco 3600 Series Hardware Installation Guide, Cisco Network Modules Hardware Installation Guide, and Cisco WAN Interface Cards Hardware Installation Guide.
Each NEBS/ETSI kit ships with the following rack-mount brackets:
- The Cisco 3620 NEBS/ETSI kit is shipped with 19-inch and 23- and 24-inch combination brackets.
- The Cisco 3640 NEBS/ETSI kit is shipped with center-mount and 23- and 24-inch combination brackets.
- The Cisco 3660 NEBS/ETSI kit is shipped with 23-inch brackets.
To install the router in a rack, attach brackets to your router chassis as shown in Figure 3-1 through Figure 3-13, depending on your installation needs:
Note Use the Cisco-supplied screws for this installation.
Note If you are installing a Cisco 3620 or Cisco 3640 router in a 19-inch rack with a 17.5-inch opening, orient the rack-mount brackets so that, when installed, they do not increase the width of the chassis. (See Figure 3-1 and Figure 3-6.)
If you are installing a Cisco 3620 or Cisco 3640 router in a 19-inch EIA-standard rack with a 17.75-inch opening, orient the rack-mount brackets so that, when installed, they increase the width of the chassis. (See Figure 3-2 and Figure 3-7.)
If you are installing a Cisco 3660 router in a 19-inch rack (with a 17.5- or 17.75-inch opening), orient the rack-mount brackets so that, when installed, they increase the width of the chassis. (See Figure 3-4 and Figure 3-9.)
Figure 3-1 through Figure 3-3 show the Cisco 3620 and Cisco 3640 routers; Figure 3-4 and Figure 3-5 show the Cisco 3660 router.
Note When installed in a 19-inch rack with a 17.5-inch opening, the Cisco 3620 and 3640 routers will protrude beyond the front of the rack.

After you attach the brackets to the router, slide the router into the rack in the position shown in one of the following illustrations. Using your own screws, fasten the chassis to the rack.
Figure 3-14 through Figure 3-16 show the Cisco 3640 router in a 19-, 23-, or 24-inch rack. The procedure is similar for the Cisco 3620 router.
Figure 3-17 and Figure 3-18 show the Cisco 3660 router in a 19- or 23-inch rack.
Figure 3-19 through Figure 3-23 show the Cisco 3620, 3640, and 3660 routers in a center-mount rack.

The following warning applies to Cisco 3660 routers:
 | Warning
Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface modules. These handles were not designed to support the weight of the chassis. |

You can now install network modules and WAN interface cards and make network connections. For instructions, see these publications: Cisco 3600 Series Hardware Installation Guide, Cisco Network Modules Hardware Installation Guide, Cisco WAN Interface Cards Hardware Installation Guide, Cisco Software Configuration Guide, and any other configuration notes shipped with your router and components.
Note The shielded cables in your NEBS/ETSI kit replace the cables originally shipped with your router. The console cable is blue, and the auxiliary cable is black.
The Ethernet cable is yellow and ships with the Cisco 3660 NEBS/ETSI kit only (ACS-3660 NEBS/ETSI=).
