See the section "Connecting the Console Terminal and Modem" later in this chapter for instructions on connecting a console terminal.

•Modem for remote system access (optional).

Setting Up the Chassis

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 fits the needs of your network.

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 Identifying the Rubber 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, as shown in .

Figure 3-2 Installing the Rubber 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.

Rack-Mounting the Chassis

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

Figure 3-11 Attaching the Chassis to the 24-Inch Rack—Rear Panel Forward

Wall-Mounting the Chassis

Use the smaller brackets (for use with a 19-inch rack) to wall-mount the chassis. The smaller brackets provide the most stable position for the chassis.

Take the following steps to wall-mount the chassis:

Step 1 Attach the brackets as shown in Figure 3-12.

Figure 3-12 Attaching the Wall-Mount Brackets

Step 2 Attach the chassis assembly to the wall as shown in Figure 3-13, 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.

•For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top.

Caution   
To prevent the chassis from pulling away from the wall when cables are attached, align the brackets and screws with a vertical wall stud. (See Figure 3-13.) To ensure adequate ventilation, make sure there is clearance between the router and the wall.

Figure 3-13 Wall-Mounting the Chassis

Wiring the DC Power Supply

If you ordered a Cisco 2524 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. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

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

shows the DC power supply terminal block. Take the following steps to wire the terminal block:

Step 1 Attach the appropriate lugs at the wire end of the power supply cord.

Step 2 Wire the DC power supply to the terminal block, as shown in .

Warning   

The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. 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. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

Figure 3-14 DC Power Supply Connections

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. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

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. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

Connecting to the Network

This section explains how to connect the router to your network, using the Ethernet (AUI or 10BaseT) or Token Ring (STP or UTP) ports or the WAN modules.

Warning   

Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

Connecting to an Ethernet Network

If you have a Cisco 2524 router, it includes both an Ethernet AUI port and a 10BaseT port. To connect your router to an Ethernet network, you can use either the Ethernet AUI or 10BaseT port, but not both. The first port connected will work. (If you attempt to use both ports, only the 10BaseT port will work.)

You can connect the router to your Ethernet network in one of the following ways:

•Use an Ethernet AUI cable to connect the Ethernet AUI port to an Ethernet transceiver. (See .)

•Use a straight-through 10BaseT cable to connect the 10BaseT port to a 10BaseT hub. (See .)

•Use a crossover 10BaseT cable to connect the 10BaseT port to a PC network interface card. (See .)

Note   If your Ethernet connection requires jackscrews, remove the slide-latch assembly from the AUI connector and attach the jackscrews provided.

Figure 3-17 Connecting to a PC Network Interface Card

Connecting to a Token Ring Network

If you have a Cisco 2524 router, you can connect the router to your Token Ring network in one of the following ways:

•Use a shielded Token Ring lobe cable to connect the Token Ring port (DB-9) to a media attachment unit (MAU). To ensure agency compliance with electromagnetic emissions requirements (EMI), make sure the cable is shielded. (See .)

•Use a twisted-pair cable to connect the Token Ring port (RJ-45) to a Token Ring hub. (See .)

If the transmission rate of your Token Ring network is 4 Mbps, use a UTP cable. If the transmission rate of your Token Ring network is 16 Mbps, use an STP cable.

Figure 3-18 Connecting to a MAU

Figure 3-19 Connecting to a Token Ring Hub

Connecting to a WAN

Although the illustrations in this section show the Cisco 2524 router, the procedures are the same for both the Cisco 2524 and Cisco 2525 routers.

Warning   

Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.")

Take the following steps to connect the router to your WAN:

Step 1 If you have a 2-wire switched 56-kbps module, use a straight-through RJ-11-to-RJ-11 cable to connect the RJ-11 port to an RJ-11 jack. (See .)

Figure 3-20 Connecting the 2-Wire Switched 56-kbps DSU/CSU Module to an RJ-11 Jack

Step 2 If you have a 4-wire 56/64-kbps DSU/CSU module, use a straight-through RJ-48S-to-RJ-48S cable to connect the RJ-48S port to an RJ-48S jack. (See .)

Figure 3-21 Connecting the 4-Wire 56/64-kbps DSU/CSU Module to an RJ-48S Jack

Step 3 If you have a fractional T1/T1 DSU/CSU module, use a straight-through RJ-48C-to-RJ-48C cable to connect the RJ-48C port to an RJ-48C jack. (See .)

Step 4 If you have a synchronous serial module, use a serial transition cable to connect the synchronous serial port to a modem or DSU/CSU. (See .)

Figure 3-23 Connecting Synchronous Serial Cables

Step 5 If you have an ISDN BRI module (without an integrated NT1 device), use a straight-through RJ-45-to-RJ-45 cable to connect the ISDN BRI (RJ-45) port to an NT1 device. (See .)

Figure 3-24 Connecting the ISDN BRI Module to an NT1 Device

Step 6 If you have an ISDN BRI module with an integrated NT1 device, use a straight-through RJ-45-to-RJ-45 cable to connect the ISDN BRI (RJ-45) port to an RJ-45 or RJ-11 jack. (See .)

Figure 3-25 Connecting the ISDN BRI with Integrated NT1 Module to an RJ-45 Jack

Step 7 If the router is configured with fewer than three WAN modules, install a blank slot cover over each open slot to ensure proper airflow.

Step 8 Using an M 3.5 thread-forming screw (not included), attach a ground wire to the protective grounding terminal on the rear panel of the chassis.

Step 9 Connect the power cable to the router and the power source.

Connecting the Console Terminal and Modem

You use the console terminal for local administrative access to the router. You can connect only a terminal to the console port. You can use the auxiliary port with a terminal or a modem for remote access to the router.

Connecting to the Console Port

Take the following steps 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 an RJ-45 roll-over cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter. The adapters provided by Cisco Systems are labeled Terminal. Other types of adapters are not included. (See .)

Additional information on roll-over cable pinouts is provided in the appendix "Cabling Specifications for the Cisco 2524 and Cisco 2525 Routers."

Figure 3-26 Connecting the Console Terminal

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

Connecting a Modem to the Auxiliary Port

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 roll-over cable with an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter. The adapter provided by Cisco Systems is labeled Modem. (See .)
