You can set the chassis on a desktop, install it in a rack, or mount it on a wall or other flat surface. Use the procedure in this section that best meets the needs of your network. The sections are as follows:

Setting the Chassis on a Desktop

Before setting the router on a desktop, shelf, or other flat, secure surface, perform the following steps to install the rubber feet:

Step 1 Locate the rubber feet on the black adhesive strip that shipped with the chassis. (See Figure 3-1.)

Figure 3-1: Identifying the Rubbe r Feet

Step 2 Place the router upside down on a smooth, flat surface.

Step 3 Peel off the rubber feet from the black adhesive strip and place them adhesive-side down onto the five round, recessed areas on the bottom of the chassis. (See Figure 3-2.)

Figure 3-2: Installing the Rub ber Feet

Step 4 Place the router right-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.

Mounting the Chassis in a Rack

This section describes the procedures for rack-mounting the chassis. The chassis comes with brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 23- or 24-inch rack. The brackets are shown in Figure 3-3.

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:

If the rack contains only one unit, mount the unit at the bottom of the rack.
If the rack is partially filled, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.
If the rack contains stabilizing devices, install the stabilizers prior to mounting or servicing the unit in the rack.

Figure 3-3: Identifying the Bracke ts

Attaching the Brackets

To install the chassis in a rack, attach the brackets in one of the following ways:

With the front panel forward (see Figure 3-4 and Figure 3-5)
With the rear panel forward (see Figure 3-6 and Figure 3-7)
In a center-mount rack, with the rear panel forward (see Figure 3-8 )

Note Use the Cisco-supplied screws for this installation.

Note If you are installing a Cisco 2600 series 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 3-4.)

If you are installing a Cisco 2600 series router in a 19-inch EIA-standard rack with a 17.75-inch opening or a 23- or 24-inch rack, orient the rack-mount brackets so that, when installed, they increase the width of the chassis. (See Figure 3-5.)

Note The following illustrations show how to connect the bracket to one side of the chassis. The second bracket connects to the opposite side of the chassis.

Figure 3-4: Bracket Installation---Front P anel Forward (19-Inch Rack with a 17.5-Inch Opening)

Note When installed in a 19-inch rack with a 17.75-inch opening, the Cisco 2600 series routers will protrude beyond the front of the rack.

Mounting the Chassis on the Wall

Note Use 19-inch brackets (shown in Figure 3-3) to wall-mount the chassis. The small brackets provide the most stable installation for the chassis.

To wall-mount the chassis:

Step 1 Attach the brackets as shown in Figure 3-11.

Figure 3-11: Attaching the Wall-Moun t Brackets

Step 2 Attach the chassis assembly to the wall as shown in Figure 3-12 , using screws and anchors that you provide. We recommend the following:

For the best support of the chassis and cables, attach the brackets so that the screws align with a vertical wall stud. (See Figure 3-12.) This position will prevent the chassis from pulling away from the wall when cables are attached.
For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top. Make sure there is clearance between the router and the wall.

Wiring the DC Power Supply

If you ordered a router with a DC power supply, follow the directions in this section to wire the terminal block.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Warning The illustration shows the DC power supply terminal block. 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.

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.

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 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 Secure all power cabling when installing this unit to avoid disturbing field-wiring connections.

Note This product is intended for installation in restricted access areas and is approved for use with 14 AWG copper conductors only. The installation must comply with all applicable codes.

To wire the terminal block:

Step 1 Using 14 AWG copper wires, rewire the DC-input power source (-38 to -72 VDC).

Step 2 Identify the terminal block receptacles for the ground, positive, and negative power leads. (See Figure 3-13.)

Step 3 Strip 3/16" of shielding from the free end of each power lead wire that is attached to the DC-input power supply.

Step 4 Insert the three power leads into the slotted wire receptacles on the terminal block. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. (See Figure 3-14.)

Step 5 Tighten the three screws to secure the power leads in the terminal block. (See Figure 3-14.)

Connecting to a Network

This section explains how to use the Ethernet and/or Token Ring ports to connect the router to the LAN.

The cables required to connect the router to a network are not provided with the router. For ordering information, see the "Technical Assistance Center" section. For cable pinouts, refer to the online document Cisco Modular Access Router Cabling Specifications on the Documentation CD-ROM that came with your router and on Cisco Connection Online.

Note Although the illustrations in this section show the Cisco 2611 router, the procedures are the same for all of the Cisco 2600 series routers.

Warning Do not work on the system, or connect or disconnect cables during periods of lightning activity.

Depending on your router model, do one of the following to connect your router to
a network:

Cisco 2610 or Cisco 2611---Connect the Ethernet 10BaseT port to an Ethernet hub, as shown in Figure 3-15. Or, connect the Ethernet 10BaseT port directly to a switch such as a Cisco Catalyst 3900.

Figure 3-15: Connecting an Ethe rnet Hub

Cisco 2612 or Cisco 2613---Connect the Token Ring port (RJ-45) to a switch such as a Cisco Catalyst 3900, as shown in Figure 3-16. To ensure agency compliance with electromagnetic emissions requirements (EMI), ensure that the lobe cable is shielded.

Figure 3-16: Connecting a Switch

Cisco 2620, Cisco 2621, Cisco 2650, or Cisco 2651---Connect the Ethernet 10/100BaseT port to an Ethernet hub, as shown in Figure 3-17. Or, connect the Ethernet 10/100BaseT port directly to a switch such as a Cisco Catalyst 3900.

Figure 3-17: Connecting an Ethernet Hub

Connecting the Console Terminal and Modem

Your router includes asynchronous serial console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal) or remotely (with a modem).

Identifying a Rollover Cable

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 3-18.) If your cable came from Cisco Systems, 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).

Figure 3-18: Identifying a Rollover Ca ble

Connecting to the Console Port

To connect a terminal (an ASCII terminal or a PC running terminal emulation software) to the console port on the router:

Step 1 Connect the terminal using the thin, flat, RJ-45-to-RJ-45 rollover cable (looks like a telephone cable) and an RJ-45-to-DB-9 or RJ-45-to-DB-25 adapter (labeled TERMINAL). (See Figure 3-19.)

Note The RJ-45-to-DB-25 adapter (Cisco part number 29-0810-01) can be purchased from Cisco.

Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.

For information on console port pinouts, refer to the online document Cisco Modular Access Router Cabling Specifications on the Documentation CD-ROM that accompanied your router package and on Cisco Connection Online.

Figure 3-19: Connecting a Console Term inal

Connecting a Modem to the Auxiliary Port

To connect a modem to the auxiliary port on the router:

Step 1 Connect a modem to the auxiliary port using the thin, flat, RJ-45-to-RJ-45 rollover cable (looks like a telephone cable) with the RJ-45-to-DB-25 adapter (labeled MODEM) included with the router. (See Figure 3-20.)

Step 2 Make sure that your modem and the auxiliary port on the router are configured for the same transmission speed (38400 baud is typical) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
