Setting the Chassis on a Tabletop

The location of the chassis should be placed to avoid inadequate ventilation; inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult.

Note For help planning the location of your chassis, see the "Site Requirement Guidelines" section.

We strongly recommend that you provide a chassis ground connection. See the "Attaching a System Ground Connection" section for instructions.

Attach the rubber feet as shown in Figure 3-1. Rubber feet are included in the accessory kit that shipped with your router.For help planning the location of your chassis, see the "Site Requirement Guidelines" section.

Figure 3-1 Attaching the Rubber Feet

This completes the general tabletop or workbench installation.

Rack-Mounting the Chassis

This section describes how to rack-mount the chassis in a standard four-post equipment rack. The router arrives with 19-inch rack-mount brackets and larger brackets for use with a 23- or 24-inch rack. (See Figure 3-2.)

Note For help planning your equipment rack configuration, see the "Rack-Mounting Guidelines" section.

Figure 3-2 Standard Rack-Mount Brackets

Attaching the Brackets

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

•Front panel forward (see Figure 3-3)

•Back panel forward (see Figure 3-4)

Note Although the installations show the 19-inch brackets, the procedure is the same for the 24-inch brackets.

Figure 3-3 Standard Bracket Installation—Front Panel Forward

Figure 3-4 Standard Bracket Installation—Back Panel Forward

Installing the Chassis in a Rack

After the brackets are secured to the chassis, you can rack-mount the router. Using the screws that you provide, attach the chassis to the rack as shown in Figure 3-5. You need two people to install the chassis in the rack—one person to hold the router and one person to secure it to the rack.

If you rack-mount the router with the back panel forward, you might need to attach the system ground connection before you rack-mount the router. For instructions on how to connect the system ground, see the next section, "Attaching a System Ground Connection."

Figure 3-5 Attaching the Chassis to the Rack—Back Panel Forward

Attaching a System Ground Connection

Before you connect power or turn on power to your router, we strongly recommend that you provide an adequate chassis ground (earth) connection for your router's chassis. Chassis grounding receptacles are provided on each router chassis.

You will need the following parts and tools:

•One grounding lug—Must have two M3.5 screw holes that have a 0.63-inch (16.002-mm) spacing between them, and a wire receptacle large enough to accept a 6-American Wire Gauge (AWG) multistrand, copper wire. This grounding lug is provided in the accessory kit.

•Two slotted hexhead M3.5 x 7-mm thread-forming machine screws. These screws are provided in the accessory kit.

•One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108 inch (2.743 mm) of insulation, for a total wire diameter of approximately 0.27 inch (6.858 mm). The wire's length is dependent on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

•Flat-blade screwdriver.

•Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding lug.

•Wire stripper.

To attach the grounding lug to the chassis grounding receptacles, complete the following steps:

Step 1 Strip one end of the 6-AWG wire approximately 0.75 inch (19.05 mm) using the wire stripper.

Step 2 Insert the 6-AWG wire into the wire receptacle on the grounding lug. (See Figure 3-6.)

Figure 3-6 Attaching the Ground Wire to the Grounding Lug

Step 3 Crimp the wire receptacle around the wire using the crimping tool.

Step 4 Insert the two screws through the holes in the grounding lug. (See Figure 3-6.) Ensure that the grounding lug does not interfere with other router hardware.

Step 5 Locate the chassis grounding receptacles on your router chassis. (See Figure 3-7.)

Figure 3-7 Attaching the Grounding Lug to the Chassis Grounding Receptacles

Step 6 Tighten the grounding lug screws using the flat-blade screwdriver. Do not overtighten the screws.

Step 7 Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure adequate chassis ground.

This completes the procedure for attaching a ground connection.

Attaching the Cable-Management Bracket

To install the cable-management bracket on the router, complete the following steps:

Step 1 Locate the chassis grounding receptacles on the rear sides of the chassis. Both rear sides of Cisco 7100 series chassis have two grounding receptacles. (See Figure 3-8.)

Step 2 Attach the cable-management bracket to the two grounding receptacles that were not used to ground the chassis in the "Attaching a System Ground Connection" section.

Step 3 Align the cable-management bracket to the vacant receptacles. Ensure the two flanges on the bracket are facing away from the chassis.

Step 4 Thread two M3.5 x 7-mm slotted hexhead screws through the bracket and into the chassis.

Step 5 Tighten the screws using a flat-head screwdriver.

Step 6 Secure any interface cables to the bracket flanges, using tie wraps.

Figure 3-8 Attaching the Cable-Management Bracket to the Chassis

This completes the steps for installing the cable-management bracket on a Cisco 7100 series router. Carefully lace interface cables through the cable-management bracket as needed.

Connecting to the Network

This section describes how to connect the router to your network. Cables to connect the router to a network are not provided. Contact customer service for ordering information. (See the "Cisco.com" section.) For cable product numbers and port pinouts, see "Cable Specifications."

The router arrives with the integrated services module (ISM), VPN Acceleration Module (VAM), and modular port adapter already installed, unless you order the VAM or modular port adapter as a spare. See the installation and configuration note for the specific port adapter, and the "Port Adapters" section for more information on port adapters. See the Integrated Service Adapter and Integrated Service Module Installation and Configuration guide and the "Integrated Service Module (ISM)/Integrated Service Adapter (ISA)" section for information on the ISM and ISA. See the VPN Acceleration Module (VAM) Installation and Configuration guide and the "VPN Acceleration Module (VAM)" section for information on the VAM.

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

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.

Connecting the Fast Ethernet Ports

The 10BaseT/100BaseTX Fast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications for 10-Mbps and 100-Mbps transmission over unshielded twisted-pair (UTP) cables. These ports also support autosensing and autonegotiation of the proper transmission mode (half duplex or full duplex) with an attached device.

Each Fast Ethernet port has an RJ-45 connector that supports standard straight-through and crossover Category 3 or Category 5 UTP cable. Cisco Systems does not supply Category 3 or Category 5 UTP RJ-45 cables; these cables are available commercially.

Use Category 3 UTP crossover cables when connecting a 10BaseT port to a hub or use Category 3 UTP straight-through cables when connecting to an end station.

Use Category 5 UTP crossover cables when connecting 100BaseTX to a hub or use Category 5 UTP straight-through cables when connecting to an end station.

To connect the Fast Ethernet port to an Ethernet hub, use the following procedure:

Step 1 Attach the appropriate cable directly to the receptacle on the router. (See Figure 3-9.)

Step 2 Attach the network end of the cable to an Ethernet hub or end station.

Figure 3-9 Connecting the LAN Port to an Ethernet Hub

Note For more information, see the "Fast Ethernet Port Cables and Pinouts" section.

Connecting the Cisco 7120-4T1 and Cisco 7140-8T

The four T1 ports on the Cisco 7120-4T1 and eight T1 ports on the Cisco 7140-8T and adapter cables allow a high density of interface ports, regardless of the size of the connectors typically used with each electrical interface type. All ports use an identical 60-pin D-shell receptacle that supports all interface types:

•EIA/TIA-232

•V.35

•EIA/TIA-449

•X.21

•EIA-530

Each port requires a serial adapter cable, which provides the interface between the high-density serial port and the standard connectors that are commonly used for each electrical interface type.

The adapter cable determines the electrical interface type and mode of the port (data terminal equipment [DTE] or data communications equipment [DCE]) to which it is connected.

At system startup or restart, the network processor polls the interfaces and determines the electrical interface type of each port (according to the type of cable attached). However, it does not necessarily repoll an interface when you change the cable. To ensure that the system recognizes the new interface type, use the shutdown interface command before replacing the cable. After you replace the cable, use the no shutdown interface command to enable the interface.

To connect a serial cable to the network, use the following procedure:

Step 1 Attach the appropriate serial cable directly to the receptacle on the router and tighten the strain-relief screws. (See .)

Step 2 Attach the network end of the serial cable to a data service unit (DSU), channel service unit (CSU), DTE, or other external synchronous serial equipment and tighten the strain-relief screws.

Figure 3-10 Connecting the T1 WAN Serial Ports on the Cisco 7120-4T1 or Cisco 7140-8T

Caution Serial interface cables must be attached correctly or damage to the cable plug will result. Attempting to force a cable plug on the 60-pin receptacle can damage the plug. (See "Cable Specifications," for additional information.)

Note For more information, see the "Cisco 7120-4T1 and Cisco 7140-8T Cables and Pinouts" section.

Connecting the Cisco 7120-T3, Cisco 7120-E3, Cisco 7140-2T3, and Cisco 7140-2E3

Use a 75-ohm coaxial cable to connect your router to a T3 or E3 serial network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The T3 or E3 serial ports on the router are considered to be DTE devices.

The Cisco 7100 T3 and E3 models have the following port configurations:

•Cisco 7120-T3—One T3 serial port

•Cisco 7120-E3—One E3 serial port

•Cisco 7140-2T3—Two T3 serial ports

•Cisco 7140-2E3—Two E3 serial ports

Each T3 or E3 serial port has two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco product number CAB-ATM-DS3/E3) is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco 75-ohm coaxial cable is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for T3 and E3 transmissions is 1300 feet (396 meters).

Note For E3 (75-ohm) connections, you must have ferrite beads on the 75-ohm coaxial cable and electromagnetic interference (EMI) decoupling clips on the receiver end of the cable (see Figure 3-12) if compliance with European certification standards for emission control is required (EN55022/CISPR22 Class B for radiated emission levels).

Note The T3 and E3 ports support several types of integrated DSUs. For a listing of the interoperability guidelines, see "Cable Specifications."

To connect the T3 or E3 port to the network, use the following procedure:

Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-11 and Figure 3-12.)

Step 2 Attach the network end of the cable to the external synchronous serial equipment.

Figure 3-11 Connecting the T3 WAN Serial Ports on the Cisco 7140-2T3

Figure 3-12 Connecting the E3 WAN Serial Ports on the Cisco 7120-E3

You can test the DTE-to-DCE cable connection by using the loopback command.

Note For more information, see the "Cisco 7120-T3, Cisco 7120-E3, Cisco 7140-2T3, and Cisco 7140-2E3 Cables" section.

Connecting the Cisco 7120-AT3, Cisco 7120-AE3, Cisco 7140-2AT3, and Cisco 7140-2AE3

Use a 75-ohm coaxial cable to connect your router to an ATM T3 or E3 network. The cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The ATM T3 or E3 ports on the router are considered DTE devices.

The Cisco 7120 series ATM models have the following port configurations:

•Cisco 7120-AT3—One ATM T3 port

•Cisco 7120-AE3—One ATM E3 port

•Cisco 7140-2AT3—Two ATM T3 ports

•Cisco 7140-2AE3—Two ATM E3 ports

AT3 or AE3 ports consist of two connectors, transmit and receive. The 75-ohm coaxial cable (Cisco product number CAB-ATM-DS3/E3) is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco 75-ohm coaxial cable is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for T3 and E3 transmissions is 1300 feet (396 meters).

Note To ensure compliance with EMI and European certification standards for emission control (EN55022/CISPR22 Class B for radiated emission levels), the Tx and Rx cables should be tied together along their entire length, and ferrite beads should be installed on each cable near the Tx and Rx connectors.

To connect the ATM T3 or E3 port to the network, use the following procedure:

Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-13.)

Step 2 Attach the network end of the cable to the external synchronous serial equipment.

Figure 3-13 Connecting the ATM T3 WAN Ports on the Cisco 7140-2AT3

Figure 3-14 Connecting the ATM E3 WAN Ports on the Cisco 7140-2AE3

Note For more information, see the "Cisco 7120-AT3, Cisco 7140-2AT3, Cisco 7120-AE3, Cisco 7140-2AE3, Cisco 7120-SMI3, and Cisco 7140-2MM3 Cables" section.

Connecting the Cisco 7120-SMI3 and Cisco 7140-2MM3

The SMI3 (OC-3c/STM-1 single-mode intermediate reach) and MM3 (OC-3c/STM-1 multimode) interfaces provide an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps bidirectionally. The MM3 and SMI3 interfaces connect to the SONET/SDH, 155-Mbps multimode or single-mode optical fiber.

For SONET/SDH multimode and SONET/SDH single-mode connections, use one duplex SC connector or two simplex SC connectors. The simplex and duplex SC connectors are shipped with removable dust covers on each connector. These cables are not available from Cisco.

For information on SONET specifications for fiber-optic transmissions, understanding power budget, and assistance with approximating the power margin for multimode and single-mode transmissions, see "Cable Specifications."

Warning Class 1 laser product.

Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

To connect the ATM OC-3c/STM-1 port to the network, use the following procedure:

Step 1 Attach the appropriate fiber cable directly to the receptacle on the router. (See Figure 3-15 and Figure 3-16.)

Step 2 Attach the network end of the cable to an external DSU (an ATM network).

Connecting the Console Port and Auxiliary Port

The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the router. The console and auxiliary cable kit includes:

•RJ-45-to-RJ-45 rollover cable

•RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL)

•RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL)

•RJ-45-to-DB-25 male DCE adapter (labeled MODEM)

Connecting to the Console Port

Use the console terminal for local administrative access to the router. You can connect a terminal to the console port only.

To connect the console port to a terminal (an ASCII terminal or a PC running terminal emulation software), use the following procedure:

Step 1 Attach the appropriate cable (RJ-45 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter) directly to the receptacle on the router. (See Figure 3-17.) The adapters provided are labeled TERMINAL. Other types of adapters are not included

Step 2 Attach the other end of the cable to a terminal or PC.

Step 3 Configure the terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, 2 stop bits, and no flow control.

Note If the emulation software flow control setting is "hardware," the router does not accept input.

Figure 3-17 Connecting the Console Terminal

Note For more information, see the "Console and Auxiliary Port Cables and Pinouts" section.

Connecting a Modem to the Auxiliary Port

You can use the auxiliary port to connect a terminal or a modem for remote access to the router.

To connect the auxiliary port to a modem, use the following procedure:

Step 1 Attach the RJ-45 rollover cable with an RJ-45-to-DB-25 adapter directly to the auxiliary receptacle on the router. (See Figure 3-18.) The adapter provided is labeled MODEM.

Step 2 Attach the other end of the cable to the modem.

Step 3 Confirm that the 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.

Figure 3-18 Connecting a Modem to the Auxiliary Port

This completes the procedure for connecting a modem to the auxiliary port. For more information, see the "Cable Specifications" section.

Connecting the Power

Cisco 7120 series and Cisco 7140 series routers feature four-output switching AC power supplies that provide power factor correction and regulated outputs. Cisco 7120 series routers have one AC-input power supply and Cisco 7140 series routers have two AC-input power supplies.

Cisco 7140 series routers will operate with power connected to either of the two power supplies. The second AC-input power supply simply enables power load-sharing and redundancy. There is no primary or secondary power supply for Cisco 7140 series routers.

For information on the power supply specifications, see "System Specifications."

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

The AC power supply has double pole/neutral fusing.

Check the following conditions before you start the router:

•The port adapter is securely inserted in its slot.

•All network interface cables are connected.

•A Flash Disk or Flash memory card is installed in its PC Card slot.

•The console terminal is connected and powered on.

To connect the AC power on Cisco 7120 series routers, use the following procedure:

Step 1 Turn the power switch to the off (O) position.

Step 2 Connect one end of the power cord to the power connector on the back of the router. (See Figure 3-19.)

Figure 3-19 Connecting the AC Power Cord

Step 3 Connect the other end of the power cord to the power outlet.

Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.

To connect the AC power on Cisco 7140 series routers (for power load-sharing and redundancy), use the following procedure to connect the second power supply.

Cisco 7140 series routers will operate with power connected to either of the two power supplies. The second AC-input power supply simply enables power load-sharing and redundancy. There is no primary or secondary power supply for the Cisco 7140 series routers.

Step 1 At the back of the router, check that the power switch is in the off (O) position.

Step 2 Slide the cable-retention clip up, away from the second AC-input receptacle, and plug in the power cable.

Step 3 Secure the cable in the power supply AC-input receptacle by sliding the cable-retention clip down until it fits around the connector. The cable-retention clip provides strain relief for the AC power cable. (See Figure 3-20.)

Note For additional AC power cable strain relief, secure the cable to the power supply handle by inserting a nylon cable tie through the hole in the handle and around the cable.

Step 4 Plug the AC power supply cable for the second power supply into the AC
power source.

These ports also support autosensing and autonegotiation of the proper transmission mode (half duplex or full duplex) with an attached device. Each Fast Ethernet port has an RJ-45 connector that supports standard straight-through and crossover Category 3 or Category 5 UTP cable. Cisco Systems does not supply Category 3 or Category 5 UTP RJ-45 cables; these cables are available commercially. Use Category 3 UTP crossover cables when connecting a 10BaseT port to a hub or use Category 3 UTP straight-through cables when connecting to an end station. Use Category 5 UTP crossover cables when connecting 100BaseTX to a hub or use Category 5 UTP straight-through cables when connecting to an end station. To connect the Fast Ethernet port to an Ethernet hub, use the following procedure: Step 1 Attach the appropriate cable directly to the receptacle on the router. (See Figure 3-9.) Step 2 Attach the network end of the cable to an Ethernet hub or end station. Figure 3-9 Connecting the LAN Port to an Ethernet Hub Note For more information, see the "Fast Ethernet Port Cables and Pinouts" section. Connecting the Cisco 7120-4T1 and Cisco 7140-8T The four T1 ports on the Cisco 7120-4T1 and eight T1 ports on the Cisco 7140-8T and adapter cables allow a high density of interface ports, regardless of the size of the connectors typically used with each electrical interface type. All ports use an identical 60-pin D-shell receptacle that supports all interface types: •EIA/TIA-232 •V.35 •EIA/TIA-449 •X.21 •EIA-530 Each port requires a serial adapter cable, which provides the interface between the high-density serial port and the standard connectors that are commonly used for each electrical interface type. The adapter cable determines the electrical interface type and mode of the port (data terminal equipment [DTE] or data communications equipment [DCE]) to which it is connected. At system startup or restart, the network processor polls the interfaces and determines the electrical interface type of each port (according to the type of cable attached). However, it does not necessarily repoll an interface when you change the cable. To ensure that the system recognizes the new interface type, use the shutdown interface command before replacing the cable. After you replace the cable, use the no shutdown interface command to enable the interface. To connect a serial cable to the network, use the following procedure: Step 1 Attach the appropriate serial cable directly to the receptacle on the router and tighten the strain-relief screws. (See .) Step 2 Attach the network end of the serial cable to a data service unit (DSU), channel service unit (CSU), DTE, or other external synchronous serial equipment and tighten the strain-relief screws. Figure 3-10 Connecting the T1 WAN Serial Ports on the Cisco 7120-4T1 or Cisco 7140-8T Caution Serial interface cables must be attached correctly or damage to the cable plug will result. Attempting to force a cable plug on the 60-pin receptacle can damage the plug. (See "Cable Specifications," for additional information.) Note For more information, see the "Cisco 7120-4T1 and Cisco 7140-8T Cables and Pinouts" section. Connecting the Cisco 7120-T3, Cisco 7120-E3, Cisco 7140-2T3, and Cisco 7140-2E3 Use a 75-ohm coaxial cable to connect your router to a T3 or E3 serial network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The T3 or E3 serial ports on the router are considered to be DTE devices. The Cisco 7100 T3 and E3 models have the following port configurations: •Cisco 7120-T3—One T3 serial port •Cisco 7120-E3—One E3 serial port •Cisco 7140-2T3—Two T3 serial ports •Cisco 7140-2E3—Two E3 serial ports Each T3 or E3 serial port has two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco product number CAB-ATM-DS3/E3) is available only from Cisco Systems; it is not available from outside commercial cable vendors. The Cisco 75-ohm coaxial cable is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for T3 and E3 transmissions is 1300 feet (396 meters). Note For E3 (75-ohm) connections, you must have ferrite beads on the 75-ohm coaxial cable and electromagnetic interference (EMI) decoupling clips on the receiver end of the cable (see Figure 3-12) if compliance with European certification standards for emission control is required (EN55022/CISPR22 Class B for radiated emission levels). Note The T3 and E3 ports support several types of integrated DSUs. For a listing of the interoperability guidelines, see "Cable Specifications." To connect the T3 or E3 port to the network, use the following procedure: Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-11 and Figure 3-12.) Step 2 Attach the network end of the cable to the external synchronous serial equipment. Figure 3-11 Connecting the T3 WAN Serial Ports on the Cisco 7140-2T3 Figure 3-12 Connecting the E3 WAN Serial Ports on the Cisco 7120-E3 You can test the DTE-to-DCE cable connection by using the loopback command. Note For more information, see the "Cisco 7120-T3, Cisco 7120-E3, Cisco 7140-2T3, and Cisco 7140-2E3 Cables" section. Connecting the Cisco 7120-AT3, Cisco 7120-AE3, Cisco 7140-2AT3, and Cisco 7140-2AE3 Use a 75-ohm coaxial cable to connect your router to an ATM T3 or E3 network. The cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The ATM T3 or E3 ports on the router are considered DTE devices. The Cisco 7120 series ATM models have the following port configurations: •Cisco 7120-AT3—One ATM T3 port •Cisco 7120-AE3—One ATM E3 port •Cisco 7140-2AT3—Two ATM T3 ports •Cisco 7140-2AE3—Two ATM E3 ports AT3 or AE3 ports consist of two connectors, transmit and receive. The 75-ohm coaxial cable (Cisco product number CAB-ATM-DS3/E3) is available only from Cisco Systems; it is not available from outside commercial cable vendors. The Cisco 75-ohm coaxial cable is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for T3 and E3 transmissions is 1300 feet (396 meters). Note To ensure compliance with EMI and European certification standards for emission control (EN55022/CISPR22 Class B for radiated emission levels), the Tx and Rx cables should be tied together along their entire length, and ferrite beads should be installed on each cable near the Tx and Rx connectors. To connect the ATM T3 or E3 port to the network, use the following procedure: Step 1 Attach the appropriate coaxial cable directly to the receptacle on the router. (See Figure 3-13.) Step 2 Attach the network end of the cable to the external synchronous serial equipment. Figure 3-13 Connecting the ATM T3 WAN Ports on the Cisco 7140-2AT3 Figure 3-14 Connecting the ATM E3 WAN Ports on the Cisco 7140-2AE3 Note For more information, see the "Cisco 7120-AT3, Cisco 7140-2AT3, Cisco 7120-AE3, Cisco 7140-2AE3, Cisco 7120-SMI3, and Cisco 7140-2MM3 Cables" section. Connecting the Cisco 7120-SMI3 and Cisco 7140-2MM3 The SMI3 (OC-3c/STM-1 single-mode intermediate reach) and MM3 (OC-3c/STM-1 multimode) interfaces provide an interface to ATM switching fabrics for transmitting and receiving data at rates of up to 155 Mbps bidirectionally. The MM3 and SMI3 interfaces connect to the SONET/SDH, 155-Mbps multimode or single-mode optical fiber. For SONET/SDH multimode and SONET/SDH single-mode connections, use one duplex SC connector or two simplex SC connectors. The simplex and duplex SC connectors are shipped with removable dust covers on each connector. These cables are not available from Cisco. For information on SONET specifications for fiber-optic transmissions, understanding power budget, and assistance with approximating the power margin for multimode and single-mode transmissions, see "Cable Specifications." Warning Class 1 laser product. Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. To connect the ATM OC-3c/STM-1 port to the network, use the following procedure: Step 1 Attach the appropriate fiber cable directly to the receptacle on the router. (See Figure 3-15 and Figure 3-16.) Step 2 Attach the network end of the cable to an external DSU (an ATM network). Figure 3-15 Connecting the ATM SMI WAN Ports on the Cisco 7120-SMI3 Figure 3-16 Connecting the ATM MM WAN Ports on the Cisco 7140-2MM3 Note For more information, see the "Cisco 7120-AT3, Cisco 7140-2AT3, Cisco 7120-AE3, Cisco 7140-2AE3, Cisco 7120-SMI3, and Cisco 7140-2MM3 Cables" section. Connecting the Console Port and Auxiliary Port The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the router. The console and auxiliary cable kit includes: •RJ-45-to-RJ-45 rollover cable •RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL) •RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL) •RJ-45-to-DB-25 male DCE adapter (labeled MODEM) Connecting to the Console Port Use the console terminal for local administrative access to the router. You can connect a terminal to the console port only. To connect the console port to a terminal (an ASCII terminal or a PC running terminal emulation software), use the following procedure: Step 1 Attach the appropriate cable (RJ-45 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter) directly to the receptacle on the router. (See Figure 3-17.) The adapters provided are labeled TERMINAL. Other types of adapters are not included Step 2 Attach the other end of the cable to a terminal or PC. Step 3 Configure the terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, 2 stop bits, and no flow control. Note If the emulation software flow control setting is "hardware," the router does not accept input. Figure 3-17 Connecting the Console Terminal Note For more information, see the "Console and Auxiliary Port Cables and Pinouts" section. Connecting a Modem to the Auxiliary Port You can use the auxiliary port to connect a terminal or a modem for remote access to the router. To connect the auxiliary port to a modem, use the following procedure: Step 1 Attach the RJ-45 rollover cable with an RJ-45-to-DB-25 adapter directly to the auxiliary receptacle on the router. (See Figure 3-18.) The adapter provided is labeled MODEM. Step 2 Attach the other end of the cable to the modem. Step 3 Confirm that the 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. Figure 3-18 Connecting a Modem to the Auxiliary Port This completes the procedure for connecting a modem to the auxiliary port. For more information, see the "Cable Specifications" section. Connecting the Power Cisco 7120 series and Cisco 7140 series routers feature four-output switching AC power supplies that provide power factor correction and regulated outputs. Cisco 7120 series routers have one AC-input power supply and Cisco 7140 series routers have two AC-input power supplies. Cisco 7140 series routers will operate with power connected to either of the two power supplies. The second AC-input power supply simply enables power load-sharing and redundancy. There is no primary or secondary power supply for Cisco 7140 series routers. For information on the power supply specifications, see "System Specifications." Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. The AC power supply has double pole/neutral fusing. Check the following conditions before you start the router: •The port adapter is securely inserted in its slot. •All network interface cables are connected. •A Flash Disk or Flash memory card is installed in its PC Card slot. •The console terminal is connected and powered on. To connect the AC power on Cisco 7120 series routers, use the following procedure: Step 1 Turn the power switch to the off (O) position. Step 2 Connect one end of the power cord to the power connector on the back of the router. (See Figure 3-19.) Figure 3-19 Connecting the AC Power Cord Step 3 Connect the other end of the power cord to the power outlet. Warning The plug-socket combination must be accessible at all times because it serves as the main disconnecting device. To connect the AC power on Cisco 7140 series routers (for power load-sharing and redundancy), use the following procedure to connect the second power supply. Cisco 7140 series routers will operate with power connected to either of the two power supplies. The second AC-input power supply simply enables power load-sharing and redundancy. There is no primary or secondary power supply for the Cisco 7140 series routers. Step 1 At the back of the router, check that the power switch is in the off (O) position. Step 2 Slide the cable-retention clip up, away from the second AC-input receptacle, and plug in the power cable. Step 3 Secure the cable in the power supply AC-input receptacle by sliding the cable-retention clip down until it fits around the connector. The cable-retention clip provides strain relief for the AC power cable. (See Figure 3-20.) Note For additional AC power cable strain relief, secure the cable to the power supply handle by inserting a nylon cable tie through the hole in the handle and around the cable. Step 4 Plug the AC power supply cable for the second power supply into the AC power source.
