This chapter describes how to install your Cisco 3600 series router and connect it to networks and external devices. It contains the following sections:
 | Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
You can set the chassis on a desktop, install it in a rack, or mount it on a wall or other flat surface. Select the procedure that best meets the needs of your network:
For desktop or shelf mounting, use the rubber "feet" shipped on a black adhesive strip with the chassis. They protect the chassis and provide a nonskid surface.
Take the following steps to attach the rubber feet:
Step 1 Locate the rubber feet that shipped with the chassis.
Step 2 Place the router upside-down on a smooth, flat surface.
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. |
Step 3 Peel the rubber feet off the black adhesive strip and place them adhesive-side down at each corner of the underside of the chassis.
Step 4 Place the router top-side up on a flat, smooth, secure surface.
 | Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg). Excessive weight on top could damage the chassis. |
After the router has been installed, you can:
If you are planning to rack-mount the router, do so before making network and power connections. If you need to install network modules or WAN and voice interface cards, you can do so either before or after rack-mounting the router. Ideally, you would install modules or WAN interface cards when you have the best access to the router's rear panel.
The router is shipped with one set of brackets and the screws to attach them to the router chassis.
Figure 3-1 through Figure 3-3 shows both sizes of brackets for the various routers.
To install the router in a rack, attach brackets to your router chassis as shown in Figure 3-4 through Figure 3-16, depending on your installation needs:
Figure 3-4 through Figure 3-6 show the Cisco 3620 and Cisco 3640 routers; Figure 3-7 and Figure 3-8 show the Cisco 3660 router.
Figure 3-9 through Figure 3-11 show the Cisco 3640 router; the procedure is similar for the Cisco 3620 router. Figure 3-12 and Figure 3-13 show the Cisco 3660 router.
Figure 3-14 through Figure 3-16 show how to install brackets for a center-mounted rack installation.
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 3-17 through Figure 3-19 show the Cisco 3640 router in a standard 19-, 23-, or 24-inch rack. The procedure is similar for the Cisco 3620 router.
Figure 3-20 and Figure 3-21 show the Cisco 3660 router in a standard 19- or 23-inch rack.
Figure 3-22 through Figure 3-26 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. |
Attach the cable guides to the rack-mounting brackets on each side of the chassis as shown in Figure 3-27 through Figure 3-30.
After the router has been installed, you can:
This section explains how to mount the Cisco 3640 or 3620 router on a wall. If you have questions or need help with the wall-mounting procedure, see Appendix A "Troubleshooting."
If you are planning to wall-mount your router, do so before making network and power connections. 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 of the router.
By default, the router is shipped with 19-inch rack-mount brackets which can also be used for wall-mounting. If you had ordered the 23- or 24-inch brackets, either pair could be used to wall-mount your router.
To install the Cisco 3620 or 3640 router on a wall, first attach the brackets on each side of the chassis as shown in Figure 3-31 or Figure 3-32, using plastic washers and slotted hex-head screws. Position the washers so that the narrow shoulder faces the router chassis.
After fastening the brackets to the chassis, follow this procedure to mount it on the wall (see Figure 3-33 or Figure 3-34):
Step 1 Using the brackets as a template, mark and drill holes on the board where you will fasten the router. Do not attach the router to the board yet.
Step 2 Locate the wall studs where you plan to attach the router.
 | Caution The router must be fastened securely to two studs. |
Step 3 Drill wall-mount screw locations through the plywood board and studs.
Step 4 Mount the plywood board on the wall, using your own 3/16 x 2-1/2 inch or larger wood screws.
Step 5 Using your own screws, approximately number 6 x 1/2-inch (depending on the thickness of the board), fasten the router to the board by the mounting brackets. (See Figure 3-33 or Figure 3-34.)
After the router has been installed, you can:
The telco version of the Cisco 3660 router is shipped with a chassis shield that is installed as follows:
Step 1 Align the chassis shield with the rear panel of the router. (See Figure 3-35.)
Step 2 Secure the louvered chassis shield by tightening the two captive screws at the side of the shield. (See Figure 3-35.)
Step 3 If necessary, remove one or more of the cable panels on the chassis shield (see Figure 3-36), and route cables through this opening.
This prevents the cables from being bent or stressed by the chassis shield.
This section describes how to connect a console terminal and a modem to the router. You can connect only a terminal to the console port. Use the auxiliary port with a terminal or a modem for remote access to the router.
These ports provide administrative access to your router either locally (with a console terminal) or remotely (with a modem).
Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure 3-37.) If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).
Take the following steps to connect a terminal or a PC running terminal emulation software to the console port on the router:
Step 1 Connect the terminal using an RJ-45 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter (labeled TERMINAL). (See Figure 3-38 through Figure 3-40.)
For cable pinouts, see the online publication Cisco Modular Access Router Cable Specifications available both on the Documentation CD-ROM and CCO.
Step 2 Configure your terminal or terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.
Take the following steps to connect a modem to the auxiliary port on the router:
Step 1 Connect a modem to the auxiliary port using an RJ-45 rollover cable with an RJ-45-to-DB-25 adapter. (See Figure 3-41 through Figure 3-43.) The provided adapter is labeled MODEM. For cable pinouts, see the online publication Cisco Modular Access Router Cable Specifications available both on the Documentation CD-ROM and CCO.
Step 2 Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115200 bps is supported) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.
This section explains how to connect AC or DC power to Cisco 3600 series routers, and how to power up both AC- and DC-powered routers.
If you have a DC-powered router, see the "Connecting Routers to a DC-Input Power Supply" section. If you have an AC-powered router, see the "Powering On the Router" section.
| Warning This product relies on the building's installation or power supply for short circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker no larger than 60 VDC, 15A U.S. is used on all current-carrying conductors. |
If you ordered the router with a DC-input power supply, follow the directions in this section for proper wiring. A router with a DC-input power supply has a terminal block cover in place of a three-pronged connector for an AC power cord.
Depending on the type of router you are installing, see one of the following:
Figure 3-44 and Figure 3-45 show the router DC-input power supply terminal block.
Take the following steps to wire the terminal block:
Step 1 Use 14-AWG copper wires to connect DC-input power to the power supply.
Step 2 Attach the appropriate lugs at the wire end of the power supply cord.
Step 3 Wire the DC-input power supply to the terminal block as shown in Figure 3-44 and Figure 3-45.
| Warning This warning applies only to units equipped with DC input power supplies. Wire the DC power supply using the appropriate lugs at the wiring end. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. |
| Caution Do not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb. |
| Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. |
| Warning Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. |
| Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. |
| Warning Voltages might be present on the DC-input power supply terminals. Turn off the power source circuit breaker and remove the power supply before accessing the terminals. |
The Cisco 3660 router DC power supply terminal blocks are located on the power cable connector. (See Figure 3-46.)
Step 1 Use 14-AWG copper wires to connect DC-input power to the terminal blocks. Strip the shielding to expose approximately 0.4 inch (10 mm) of the wire.
| Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power source wire extends from the terminal block plug. |
Step 2 Press the corresponding orange-colored release, and insert one wire in each receptacle of the power cable connector. The spring-loaded connector retains the wires.
| Warning This warning applies only to units equipped with DC input power supplies. Wire the DC power supply using the appropriate lugs at the wiring end. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last |
Step 3 Plug the connector and power cable into the power receptacle on the power supply.
| Warning Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. |
| Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. |
| Warning Voltages might be present on the DC-input power supply terminals. Turn off the power source circuit breaker and remove the power supply before accessing the terminals. |
| Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. |
| Caution Never operate the router unless the unit is completely closed to ensure adequate cooling. |
Take the following steps to power on the router:
Step 1 For routers with AC input, plug the router's power cord into a three-terminal, single-phase power source that provides power within the acceptable range. (See the "Power Supply Considerations" section.)
| Warning This product relies on the building's installation or power supply for short circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker no larger than 60 VDC, 15A U.S. is used on all current-carrying conductors. |
Step 2 Power ON the router. The LED labeled SYSTEM on the front panel should
go on.
If you encounter problems when you power on the router, see Appendix A, "Troubleshooting."
When you have installed the router hardware, see the Software Configuration Guide (for Cisco 3600 series and Cisco 2600 series routers) included in your router package for initial software configuration information.
