This chapter describes the tasks you must perform to install your system. Sections of this chapter follow:
The router ships with optional rubber "feet." For a desktop or wall-mounted chassis, install the feet to provide adequate spacing between the chassis and the supporting surface for proper ventilation. For a rack-mounted chassis, do not install the rubber feet if the chassis is to be mounted directly above another chassis in the same rack.
The router system has three mounting options: standard 19-inch rack mount, telco rack mount, or wall mount. The procedures for the different mounting options involve removing the front panel and component tray from the chassis shell and then installing the empty shell in position before reinserting the component tray.
The optional rack-mount/wall-mount kit ships with its own set of instructions for rack and wall mounting. If you are planning to rack-mount or wall-mount the router, do so before making the network and power connections while following the procedures described in the separate rack-mount/wall-mount publication included with the rack-mount kit.
To prepare for initial startup and configuration, you must connect an EIA/TIA-232 cable between an ASCII terminal and the system console port, and you must attach the power cord. The console port and auxiliary ports have jackscrews to accommodate cables with thumbscrews. If your cable connection requires it, the jackscrews can be removed.
Follow these steps to connect your system's console port to a terminal:
Step 1 Ensure that your site meets the site preparation requirements described in the section "Preparing to Make Connections" in the chapter "Preparing for Installation."
Step 2 If you have not already done so, unpack your system referring to the section "Inspecting the System" in the chapter "Preparing for Installation."
Step 3 Attach your terminal to the EIA/TIA-232 console port with a console cable.
Make the network connections by attaching the network interface cables to the appropriate connector on the network processor modules.
If more than one network processor module of a given interface type is used in a system, the lowest unit number of a given interface type is the module closest to the power supply. (See the sections "Slot Numbering" and "Unit Numbering" in the chapter "Preparing for Installation.")
Step 1 Attach the network processor module connector labeled Token Ring to the 9-pin D-type connector of the Token Ring cable. (See Figure 3-1.)
Step 2 Attach the IEEE 802.5 connector to your media attachment unit (MAU).
When all the network connections are complete, proceed to the section "Making Final Connections to the Router."
Ethernet network processor modules contain both Ethernet AUI connectors and 10BaseT connectors. Dual Ethernet modules contain two of each type of connector interface.
For dual-port Ethernet modules (see Figure 3-2), connect either the Ethernet AUI connector or the 10BaseT connector on a specific Ethernet port, but not both connectors on the same port. For single-port Ethernet modules (see Figure 3-3), connect either the Ethernet AUI or the 10BaseT connector, but not both on the same module.
In Figure 3-2, the configuration on the left, showing two network connections attached to Port 0, is unsupported; the configuration on the right, which shows two network connections, one to Port 0 and one to Port 1, is supported.
In Figure 3-3, the single-port Ethernet module on the left shows an unsupported configuration of two network connections going to two connectors on the same port; the module on the right shows a supported connection with a single 10BaseT cable connecting to a single connector on the port.
Follow these steps to make your AUI connections.
Step 1 Attach the 15-pin D-type Ethernet port labeled AUI to the Ethernet AUI transition cable. (See Figure 2-7, Figure 2-8, and Figure 2-9 in the chapter "Preparing for Installation.")
Step 2 Attach the slide-latch connector of the same cable to your transceiver or hub.
Step 3 On a dual-port Ethernet network interface module, repeat Steps 1 and 2 for the second port.
When all your network connections are complete, proceed to the section later in this chapter, "Making Final Connections to the Router."
Follow these steps to make your 10BaseT connections.
Step 1 Attach the 10BaseT port labeled 10BaseT to the 10BaseT cable. (See Figure 2-5, Figure 2-6, and Figure 2-9 in the chapter "Preparing for Installation.")
Step 2 Attach the other end of the 10BaseT cable to your network.
Step 3 On a dual-port Ethernet network interface module, repeat steps 1 and 2 for the second port.
When all your network connections are complete, proceed to the section later in this chapter, "Making Final Connections to the Router."
The 60-pin DB-60 connector is standard on the four-port serial network processor module; the 50-pin DB-50 connector is standard on the dual serial network processor modules. Use the specific serial transition cable for the module type and the correct EIA/TIA standard connector for your modem or channel service unit/digital service unit (CSU/DSU) connector type.
 | Caution The connector on the four-port serial module is upside down. The cable should match that orientation. Ensure that the 60-pin connectors on the cable and the network processor modules match. Do not force the cable into the connector upside down. (See Figure 3-4.) |
Follow these steps to make your serial connections.
Step 1 Attach the ends of your serial transition cables to the synchronous serial ports of the serial network processor modules. (See Figure 3-5 and Figure 3-6.)
Step 2 Attach the EIA/TIA-232, EIA/TIA-449, V.35, X.21, or EIA-530 end of the cable to the channel service unit/data service unit (CSU/DSU) or modem.
| Caution For proper router operation, both ends of the 50-pin dual serial EIA/TIA-232 serial DCE cable, and any cable attached to it, must be connected. If this cable must be detached, detach the router end first. If the end away from the router is disconnected, the line connection will "flap." The interrupts generated from such a condition could cause the router to shut down. |
When all your network connections are complete, proceed to the section later in this chapter, "Making Final Connections to the Router."
Using the appropriate cable (see the following section, "BRI Cable Specifications"), connect the Basic Rate Interface (BRI) port to the Integrated Services Digital Network (ISDN) through the NT1. The common carrier will provide the NT1 connection worldwide, except in North America, where the NT1 is customer owned. The NT1 is an ISDN channel service unit/digital service unit (CSU/DSU).
 | Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages are also accessible on the network processor module in the area of the BRI port (RJ-45 connector) even when power is turned OFF. (See Figure 3-7 and Figure 3-8.) |
The BRI network processor module supports point-to-point operation at OSI Layer 1. Only one source (the transmitter) and one sink (the receiver) are actively transmitting at any time in each direction at an S interface (CCITT specification I.430 section 3.1). The BRI module does not support a point-to-multipoint wiring configuration. Because the BRI module does not support point-to-multipoint configuration, D-channel access procedures are not implemented.
The specifications for the BRI cable are given in Table 3-1.
| Parameter | High-Capacitance Cable | Low-Capacitance Cable |
|---|---|---|
| Resistance (@ 96 kHz1) | 160 ohms/km | 160 ohms/km |
| Capacitance (@ 1 kHz) | 120 nF/km2 | 30 nF/km |
| Impedance (@ 96 kHz) | 75 ohms | 150 ohms |
| Wire diameter | 0.024" (0.6 mm) | 0.024" (0.6 mm) |
| Distance limitation | 32.8' (10 m) | 32.8' (10 m) |
The BRI network processor module (see Figure 3-7 and Figure 3-8) supports eight BRI ports. Each BRI port is an RJ-45 8-pin connector. Use an appropriate cable to connect the BRI module directly to an Integrated Services Digital Network (ISDN) through an ISDN channel service unit/digital service unit (CSU/DSU) called the NT1. The common carrier will provide the NT1 connection, except in North America, where the NT1 is customer owned.
| Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages are also accessible on the BRI module in the area of the BRI port (RJ-45 connector), even when power is turned OFF. (See Figure 3-7 and Figure 3-8.) |
The BRI interface port pinout is shown in Table 3-2.
| 8 Pin1 | TE1 | NT2 | Polarity |
|---|---|---|---|
| 3 | Transmit | Receive | + |
| 4 | Receive | Transmit | + |
| 5 | Receive | Transmit | - |
| 6 | Transmit | Receive | - |
| Caution To prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. |
An external loopback RJ-45 connector, useful for isolating hardware problems on an individual BRI port, can be constructed as follows:
Step 1 Connect Pin 3 to Pin 4. (See Figure 3-7 and Figure 3-8.)
Step 2 Connect Pin 5 to Pin 6.
Step 3 Connect a 50-ohm resistor across Pin 3 and Pin 5.
With the loopback RJ-45 connector plug installed in a BRI port, use the test interface command to determine that the hardware is functioning correctly.
When on, the multiport BRI network processor module status LEDs indicate a Layer 1 connection on the corresponding port. When not on, the LEDs indicate that the link is not established on the corresponding port.
The Cisco Systems Basic Rate Interface (BRI) network processor module is a processor/interface card assembly for use within a range of data communication (gateway and router) chassis supplied by Cisco Systems throughout Europe. The BRI module is a self-contained product that provides all of the hardware necessary to allow connection of Cisco Systems' chassis to either four or eight Basic Access Integrated Switched Digital Networks (ISDN), each at the S reference point. The ISDN usage is restricted to the point-to-point mode only.
The BRI network processor module must have a dedicated S-bus connection for each of its ISDN ports. The BRI module cannot share any of its S-bus connections with other terminal equipment, therefore, no other terminals should be connected to the same S-bus as a BRI module connection.
The four or eight ISDN connections must be made to network connection points that are provided by one network vendor or public telecom operator (PTO) to ensure that common network timing exists between the ISDN ports used. Failure to observe this point may result in lost (nonrecoverable) data packets due to timing slips.
The BRI network processor module is fully transportable between compatible host chassis. The choice of each compatible chassis has no effect on the capabilities, functionality, or performance of the BRI network processor module.
The BRI network processor module consists of the following subassemblies:
The BRI network processor module provides users of compatible host routers or bridge chassis with a high-speed throughput, point-to-point connection that can be set up over the digital telecommunication network ISDN.
Read the following sections before connecting the BRI port of your router to a network.
Where your PTO has provided you with ISDN modular sockets, the BRI module can be plugged in to make the connection. Connections should only be made to a BRI module properly installed within the host chassis.
| Warning The BRI module must not be connected to the ISDN while removed from its host chassis. Damage to the equipment and injury to the user could occur. |
In certain countries, the BRI network processor module must be hardwired permanently to the S-reference connection point (your Cisco Systems dealer will advise). This is accommodated for by the use of a connect one-time-only, nonremovable plug (RJ-45 with the latch tab removed).
The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. No attempt should be made by users to tamper with or open any PTO-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect one-time-only plug) must be made only by PTO staff or suitably trained engineers.
The BRI network processor module (four or eight port options) is approved only for installation in a host chassis and with host attachments, which are either type approved for such apparatus, or covered by a General Approval.
Except at the edge connector that plugs into the host chassis expansion slot, clearance and creepage distances of X millimeters (mm) and Y mm as listed in Table 3-3 must be maintained between the cards and other parts of the host, including any other expansion cards fitted.
Note that in Table 3-3:
| Voltage Used or Generated by Other Parts of the Host or Expansion Card (Vrms or VDC)2 | Creepage (Y mm)1 | Clearance (X mm) |
|---|---|---|
| Up to 50 | 2.4 (3.8) | 2.0 |
| Up to 125 | 3.0 (4.8) | 2.6 |
| Up to 250 | 5.0 (8.0) | 4.0 |
| Up to 300 | 6.4 (10.0) | 4.0 |
Creepage and clearance distances are measured between adjacent parts as shown in Figure 3-9.
Note that in Figure 3-9, X indicates the clearance distances between cards and adjacent cards and components, and Y shows the creepage path across the surface of an insulator and between the two points indicated by X.
The power requirements of the BRI network processor module are as follows:
Ensure that the power drawn by the apparatus, together with the power drawn by any auxiliary apparatus, lies within the rating of the host chassis power supply.
The BRI network processor modules contain safety extra-low voltage (SELV) circuitry. Ensure that attachments at the interconnection ports of the apparatus are also SELV circuits. (SELV circuits are so designed and protected that, under both normal conditions and a likely fault condition, the current which can be drawn is not hazardous).
Always disconnect the host chassis from the power supply before removing any covers.
Always disconnect the host chassis from any analog telephone circuits or Basic Access ISDN (where applicable) before removing any covers.
Failure to install the BRI modules in accordance with these instructions will invalidate any telecommunication terminal equipment type approval(s).
If you have any doubt as to how to safely install the Cisco Systems BRI module correctly within a host chassis, seek advice from a qualified telecommunications engineer.
Follow these procedures to make Fiber Distributed Data Interface (FDDI) connections.
Connect a dual-attachment FDDI module as follows:
Step 1 To connect to a dual-attachment station (DAS), connect PHY-A on the FDDI module (the bottom port) to PHY-B on the other DAS using a multimode fiber-optic cable. (See Figure 3-10.)
Step 2 Connect PHY-B on the FDDI module (the top port) to PHY-A on the other DAS.
Step 3 When all your network connections are complete, proceed to the section "Connecting to an Optical Bypass Switch" later in this chapter.
Step 1 Using a multimode fiber-optic cable, connect the single-attachment module's PHY-S port through a concentrator to a single-attachment ring, or connect it point-to-point directly to another device. (See Figure 3-11.)
Step 2 When all your network connections are complete, proceed to the section "Connecting to an Optical Bypass Switch" later in this chapter.
Connect a single-mode FDDI module as follows:
Step 1 Connect the cable from the primary ring (from PHY-B at the primary ring upstream station) to the module's PHY-A receive port, labeled RCVR on the module panel. (See Figure 3-12.)
Step 2 Connect the cable to the primary ring (to PHY- A at the primary ring downstream station) to the module's PHY- B transmit port labeled XMTR.
Step 3 Connect the incoming cable from the secondary ring to the module's PHY- B receive port, labeled RCVR on the module panel.
Step 4 Connect the outgoing cable to the secondary ring to the module's PHY- A transmit port labeled XMTR on the module panel.
Step 5 When all your network connections are complete, proceed to the section "Making Final Connections to the Router" later in this chapter.
To connect the FDDI module to an external optical bypass switch (not included), use the optical bypass interface cable included with the module.
Step 1 Connect one end of the optical bypass interface cable to the six-pin circular Deutsche Industrie-Norm (DIN) connector on the FDDI module panel. (See Figure 3-10 and Figure 3-11.)
Step 2 Connect the other end of the optical bypass interface cable to the optical bypass switch.
Proceed to the section "Making Final Connections to the Router" later in this chapter.
If you installed a new CT1 or if you want to change the configuration of an existing controller, you must enter the configuration mode. If you replaced the CT1 that was previously configured, the system will recognize the new CT1 and bring it up in the existing configuration.
After you verify that the new CT1 is recognized by the Cisco 4000 series, use the privileged-level configure command to configure the new CT1 module. Be prepared with the information you will need, such as the following:

Step 3 Specify the framing type (for SONET interfaces, STS-3c is the default):
Step 4 Assign protocol addresses to the interface:
Step 5 Create the Permanent Virtual Circuits (PVCs). A PVC requires the whole path from source to destination to be setup manually. If there is a switch in the path, it has to be properly configured also. The PVC command has the format atm pvc vc-id vpi vci encap [peak-rate sustained-rate burst-size]:
Step 6 Assign the appropriate map-list to the interface:
Step 7 Enable the interface:

Step 9 Create the mapping of protocol addresses to ATM NSAP addresses, as follows:
Step 10 To complete the configuration, enter Ctrl-Z.
Step 11 Write the new configuration to memory:
Step 12 Exit the privileged level and return to the user level:
| Warning Before conducting 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. |
If you ordered a Cisco 4000 series router with a DC-input power supply, follow the directions in this section for proper wiring.
For identification purposes, Figure 3-13 shows a Cisco 4000 series router with a DC-input power supply; Figure 3-14 shows a Cisco 4000 series router with an AC-input power supply.
Figure 3-15 shows the Cisco 4000 DC-input power supply terminal block. Follow these procedures for wiring the terminal block.
Step 1 Feed the wires through the rubber grommet in the terminal block cover.
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 3-15. The proper wiring sequence is ground to ground, positive to positive, and negative to negative.
| 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-input power supply, replace the terminal block cover and screw to ensure user safety. |
Step 4 Remove the tape from the circuit breaker switch handle and restore power by moving the circuit breaker handle to the ON position.
| Caution To avoid damaging the power supply when returning the chassis to the manufacturer (for example, if a failure occurs), remove the power supply terminal block cover so that it will fit in the shipping container. |
This completes the procedure for wiring the DC-input power supply.
| Warning Never operate the router unless the unit is completely closed. This ensures both your safety and adequate cooling. |
Follow this procedure to make the final connections to the router:
Step 1 For routers with AC power input, plug the system power cord into a 3-terminal, single-phase power source that provides power within the acceptable range (200W, 85 to 264 VAC, 50 to 60 Hz). For routers with DC power input, wire the power supply as shown in Figure 3-15.
Step 2 Turn ON the system power switch. The LED on the front marked Power should light. (See Figure 1-1.)
Step 3 Verify that the OK light located on the right side of the front panel (see Figure 1-1) goes ON after a few seconds delay.
Your configuration can be designated with either the setup command facility or with the configuration command. For more information on software commands, refer to the appropriate software publications.
