This chapter explains the procedures to install and connect the Cisco uBR7200 series universal broadband router. The chapter contains the following sections:
A rack-mount and cable-management kit is included in the shipping container. The rack-mount brackets in the kit are for mounting the Cisco uBR7200 series in standard, 19-inch-wide, 4-post equipment racks or telco-type equipment racks. The rack-mount brackets are not suitable for use with other racks, such as 23-inch telco racks. The cable-management brackets are designed to relieve the strain on port adapter interface cables that are installed on port adapters in a Cisco uBR7200 series. If you are installing an equipment shelf or using mounting hardware other than that supplied with the chassis, review the guidelines in the "Equipment Racks" section, then proceed to the "Installing the Cisco uBR7200 Series in a Workbench or Tabletop Environment" section.
If you do not plan to install your Cisco uBR7200 series in an equipment rack, proceed to the "Installing the Cisco uBR7200 Series in a Workbench or Tabletop Environment" section.
To assist you with your installation and to provide a historical record of what was done, by whom, use the Cisco uBR7200 Series Installation Checklist in Table 3-1. Make a copy of this checklist and indicate when each procedure or verification is completed. When the checklist is completed, place it in your site log (see "Site Log") along with the other records for your new router.

The chassis mounts to two rack posts with brackets that attach to either the front, middle, or rear sides of the chassis. The inside width between the posts or mounting strips (left and right) must be at least 17.5 inches (44.45 cm).
Some equipment racks provide a power strip along the length of one of the mounting strips. Figure 3-1 shows a typical 4-post equipment rack with a power strip along one of the back posts. If your rack has this feature, consider the position of the strip when planning fastener points and ensure that you will be able to pull port adapters and other FRUs straight out of their respective slots.
The inlet and exhaust ports for cooling air are located on the right and left of the chassis, respectively, so multiple universal broadband routers can be stacked in a rack with little or no vertical clearance.
 |
Note To illustrate the different methods for rack-mounting the Cisco uBR7200 series universal broadband router, this section displays figures specific to the Cisco uBR7246. The setup necessary to rack-mount the Cisco uBR7223 is the same as for the Cisco uBR7246 and Cisco uBR7246 VXR in all cases. |
|
Note Cisco recommends the rear bracket mounting system for four-post racks. This method enables you to keep cables from protruding too far out in front of the Cisco uBR7200 series and simultaneously manage the cables at the front of the chassis with the cable management bracket. |
Mounting options are as follows:
There are two cable-management bracket configurations available when rack-mounting the Cisco uBR7200 series. In the first configuration, for a 4-post rack, the rack-mount brackets are installed at the rear of the chassis and the cable-management bracket is installed at the right front of the chassis. (See Figure 3-6.) You must install both sets of brackets before you install the chassis in the rack.
|
Note If you rack-mount a Cisco uBR7200 series from the front, you cannot install a cable-management bracket. |
In the second configuration, for a telco-type rack, the rack-mount brackets are installed at the middle of the chassis and the cable-management bracket is installed at the right front of the chassis. (See Figure 3-7.) You must install both sets of brackets before you install the chassis in the rack.
|
Note The cable-management bracket must be installed on the right side of the chassis when viewed from the front. |
This section explains how to install the rack-mount brackets and cable-management bracket on a Cisco uBR7200 series universal broadband router. Before installing the chassis in the rack, you must install a rack-mount bracket on each side of the front, middle, or rear of the chassis. If you are rack-mounting the chassis from the front, you cannot use the cable-management bracket.
If you are rack-mounting the chassis from the rear or middle of the chassis, you can install the rack-mount brackets and cable-management bracket separately; however, both rack-mount brackets and the single cable-management bracket must be installed on the chassis before the chassis is installed in the rack.
The parts and tools required for installing the rack-mount and cable-management brackets are listed in the "Tools for Installation" section.
|
Note To illustrate the different methods for installing brackets on the Cisco uBR7200 series universal broadband router, this section displays figures specific to the Cisco uBR7246. The set up necessary to install brackets on the Cisco uBR7223 is the same as for the Cisco uBR7246 and Cisco uBR7246 VXR in all cases, with the exception that only two screws are necessary to affix the bracket to the Cisco uBR7223 chassis. |
To install the rack-mount brackets and cable-management bracket on the chassis for a rear rack-mount configuration, complete the following steps:
Step 2 Align the first rack-mount bracket to the threaded holes in the right side of the chassis.
Align the rack-mount bracket to the chassis as shown in Figure 3-8.
|
Note There are eight holes in each of the rack-mount brackets for the Cisco uBR7246 VXR and Cisco uBR7246. You can use either set of four holes to align the bracket to the threaded holes in the sides of the chassis. There are only two holes in each of the rack-mount brackets for the Cisco uBR7223. |
Step 3 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips flathead screws through the rack-mount bracket and into the side of the chassis. Use a number 2 Phillips screwdriver to tighten the screws.
Step 4 Repeat Step 1 through Step 3 for the other rack-mount bracket.
Step 5 If you plan to include the cable-management bracket in your rear rack-mount configuration, align the bracket with the two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) right front side holes.
|
Note The cable-management bracket must be installed on the right side of the chassis when viewed from the front. |
Step 6 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips panhead screws through the cable-management bracket and into the chassis, and tighten the screws.
This completes the procedure for installing the rack-mount brackets and the cable-management bracket on the chassis for a rear rack-mount configuration. Proceed to the "Installing the Chassis in the Rack" section.
 |
Caution To prevent injury, review the safety precautions in "Preparing for Installation," before installing the universal broadband router in a rack. |
To install the rack-mount brackets on the chassis for a front rack-mount configuration, complete the following steps.
|
Note If you plan to use the cable-management bracket in your rack-mount configuration, you must install your rack-mount brackets on the rear of the chassis. Proceed to the "Installing Brackets on the Rear of the Chassis" section. |
Step 2 If you want the front of the chassis flush with the front of the rack, align the first rack-mount bracket to the threaded holes in the right side of the chassis as shown in Figure 3-9.
If you want the front of the chassis protruding from the rack, align the first rack-mount bracket to the threaded holes in the right side of the chassis as shown in Figure 3-10.
|
Note There are eight holes in each of the rack-mount brackets for the Cisco uBR7246 VXR and Cisco uBR7246. You can use either set of four holes to align the bracket to the threaded holes in the sides of the chassis. There are only two holes in each of the rack-mount brackets for the Cisco uBR7223. |
Step 3 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips flathead screws through the bracket and into the side of the chassis. Use a number 2 Phillips screwdriver to tighten the screws.
Step 4 Repeat Step 1 through Step 3 for the other rack-mount bracket.
This completes the procedure for installing the rack-mount brackets on the chassis for a front rack-mount configuration. Proceed to the "Installing the Chassis in the Rack" section.
|
Caution To prevent injury, review the safety precautions in "Preparing for Installation," before installing the universal broadband router in a rack. |
To install the rack-mount brackets and cable-management bracket at the middle of the chassis for a telco-type rack-mount configuration:
Step 2 Align the first rack-mount bracket to the threaded holes in the right side of the chassis.
Align the rack-mount bracket to the chassis as shown in Figure 3-11.
|
Note There are eight holes in each of the rack-mount brackets for the Cisco uBR7246 VXR and Cisco uBR7246. You can use either set of four holes to align the bracket to the threaded holes in the sides of the chassis. There are only two holes in each of the rack-mount brackets for the Cisco uBR7223 |
Step 3 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips flathead screws through the rack-mount bracket and into the side of the chassis. Use a number 2 Phillips screwdriver to tighten the screws.
Step 4 Repeat Step 1 through Step 3 for the other rack-mount bracket.
Step 5 If you plan to include the cable-management bracket in your telco-type rack-mount configuration, align the bracket with the two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) right front side holes.
|
Note The cable-management bracket must be installed on the right side of the chassis when viewed from the front. |
Step 6 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips panhead screws through the cable-management bracket and into the chassis, and tighten the screws.
This completes the procedure for installing the rack-mount brackets and cable-management bracket on the Cisco uBR7200 series. Proceed to the following section, "Installing the Chassis in the Rack."
|
Caution To prevent injury, review the safety precautions in "Preparing for Installation," before installing the universal broadband router in a rack. |
After installing the brackets on the chassis, mount the universal broadband router by securing the rack-mount brackets to four posts or mounting strips in the rack using the four slotted screws provided. Because the brackets support the weight of the entire chassis, be sure to use all four slotted screws to fasten the two rack-mount brackets to the rack posts. Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5 show typical installations in 19-inch 4-post and telco-type equipment racks.
Cisco recommends that you allow at least 2 inches (5.15 cm) of vertical clearance between the universal broadband router and any equipment directly above and below it.
To install the chassis in the rack:
Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.
 |
Tips Two people should perform Step 3 through Step 6. |
Step 3 Position the chassis so that the front end is closest to you; then lift the chassis and move it to the rack. To prevent injury, avoid sudden twists or moves.
Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the chassis) meet the mounting strips or posts on both sides of the equipment rack.
|
Tips The rack-mount bracket must be placed behind the rack post or mounting strip in the rear installation configuration. (See Figure 3-2.) |
Step 5 While keeping the brackets flush against the posts or mounting strips, position the Cisco uBR7200 series so the holes in the brackets are aligned with those in the mounting strips.
Step 6 Insert all four 10/32 x 3/8 slotted screws (two on each side) through the brackets and into the mounting strip (use the top and bottom bracket holes, as shown in Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5). Using a 7/16-inch, flat-blade screwdriver, tighten all the screws.
This completes the procedure for installing the chassis in the rack. Proceed to the "Connecting Port Adapter Cables" section to continue the installation.
The Cisco uBR7200 series universal broadband router should already be in the area where you will install it, and your installation location should already be determined. If not, refer to the "Site Requirements" section.
When installing the Cisco uBR7200 series on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following:
 |
Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage. |
Complete the following steps to install the Cisco uBR7200 series on a workbench or tabletop:
Step 2 On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, cable modem cards, the clock card, and each power supply are tightened and the port adapter retention clip is in the locked position.
Step 3 Lift the chassis by placing your hands around the chassis sides and lifting the chassis from underneath. To prevent injury, avoid sudden twists or moves.
Step 4 Place the Cisco uBR7200 series on the tabletop or workbench.
Step 5 Ensure that there is at least 3 inches (7.72 cm) of clearance at the inlet and exhaust vents of the Cisco uBR7200 series and no exhaust air from other equipment will be drawn into the chassis. Also, ensure that there is approximately 23.25 inches (59.06 cm) of clearance at the front and 19 inches (48.3 cm) at the rear of the chassis.
This completes the general installation. If you want to install a cable-management bracket on the Cisco uBR7200 series, proceed to the following section, "Installing the Cable-Management Bracket on a Cisco uBR7200 Series in a Workbench or Tabletop Environment." Otherwise, proceed to the "Connecting Port Adapter Cables" section.
To install the cable-management bracket on a Cisco uBR7200 series universal broadband router installed on a workbench or tabletop, complete the following steps:
Step 2 Align the cable-management bracket with the two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) right front threaded holes in the chassis. (See Figure 3-7.)
|
Note The cable-management bracket must be installed on the right side of the chassis when viewed from the front. |
Step 3 Thread two (Cisco uBR7223) or four (Cisco uBR7246 VXR and Cisco uBR7246) M4 x 6-mm Phillips flathead screws through the bracket and into the chassis. Use a number 2 Phillips screwdriver to tighten the screws.
This completes the steps for installing the cable-management bracket on the Cisco uBR7200 series. Proceed to the following section, "Connecting Port Adapter Cables," to continue the installation.
This section provides information on connecting port adapter, clock card, cable modem card, and I/O controller cables to your Cisco uBR7200 series universal broadband router.
The instructions for connecting the cables for each port adapter installed in the Cisco uBR7200 series universal broadband router are contained in the respective installation document for each port adapter. For example, if you are connecting the cables for a HSSI port adapter, refer to the document PA-H HSSI Port Adapter Installation and Configuration (Cisco document number 78-3280-11). This document accompanies every HSSI port adapter that is shipped from the factory as an installed item in a Cisco uBR7200 series or as a FRU. The document is also available on the Documentation CD-ROM and on Cisco Connection Online (CCO).
The console and auxiliary ports for the Cisco uBR7200 series universal broadband router are located on the I/O controller. The I/O controller also has an optional Fast Ethernet port with a media-independent interface (MII) receptacle and an RJ-45 receptacle. (See Figure 3-12 and Figure 3-13.) This section contains connection equipment and pinout information for the console, auxiliary, and Fast Ethernet ports on the I/O controller.
|
Note If you have installed an I/O controller that has an optional Fast Ethernet port with the MII receptacle and RJ-45 receptacle, you can only connect to one of the Fast Ethernet receptacles; not both. |
The I/O controller has two EIA/TIA-232 ports: a data communications equipment (DCE)-mode console port and a data terminal equipment (DTE)-mode auxiliary port. The console port is a DCE DB-25 receptacle for connecting a data terminal, which you will use to configure the interfaces and bring up the Cisco uBR7200 series universal broadband router. The auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit [CSU/DSU] or other router) to the Cisco uBR7200 series. (See Figure 3-14.)
|
Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.) |
Before connecting a terminal to the console port, configure the terminal to match the Cisco uBR7200 series console port as follows: 9600 baud, 8 data bits, no parity, 1 stop bit (9600 8N1). You need an EIA/TIA-232 DCE console cable to connect the terminal to the console port. After you establish normal universal broadband router operation, you can disconnect the terminal.
You must supply your own interface cable between the auxiliary port and the equipment you are connecting. For console and auxiliary port pinouts, refer to the following sections "Console Port Signals" and "Auxiliary Port Signals."
Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The Request To Send (RTS) signal tracks the state of the Clear to Send (CTS) input. The console port does not support modem control or hardware flow control. Table 3-2 lists the signals used on the console port. The console port requires a straight-through EIA/TIA-232 cable.
| Pin | Signal | Direction | Description |
|---|---|---|---|
1 | GND | - | Ground |
2 | TxD | <--- | Transmit Data |
3 | RxD | ---> | Receive Data |
6 | DSR | ---> | Data Set Ready (always on) |
7 | GND | - | Ground |
8 | DCD | ---> | Data Carrier Detect (always on) |
Table 3-3 lists the signals used on the auxiliary port. The auxiliary port supports hardware flow control and modem control.
| Pin | Signal | Direction | Description |
|---|---|---|---|
2 | TxD | ---> | Transmit Data |
3 | RxD | <--- | Receive Data |
4 | RTS | ---> | Request To Send (used for hardware flow control) |
5 | CTS | <--- | Clear To Send (used for hardware flow control) |
6 | DSR | <--- | Data Set Ready |
7 | Signal Ground | - | Signal Ground |
8 | CD | <--- | Carrier Detect (used for modem control) |
20 | DTR | ---> | Data Terminal Ready (used for modem control only) |
The Fast Ethernet port on the I/O controller has a single MII, 40-pin, D-shell-type connector that is configurable for 100 megabits per second (Mbps). The MII connector supports IEEE 802.3u interfaces compliant with the 100BaseX and 100BaseT standards. The single MII connection requires an external transceiver that permits connection to multimode fiber for 100BaseFX or 100BaseT4 physical media. (See Figure 3-15.)
|
Note This port does not support 10-Mbps Ethernet connectivity; only 100-Mbps Fast Ethernet. |
|
Caution Make sure input power to your Cisco uBR7200 series universal broadband router is turned OFF and the router is completely powered down before connecting an external transceiver to the Fast Ethernet port on the I/O controller. If you connect an external transceiver to the Fast Ethernet port when the Cisco uBR7200 series is powered on, the system will reset and you could lose data. The I/O controller does not support online insertion and removal (OIR). |
Depending on the type of media you use between the MII connection and your switch or hub, the network side of your 100BaseT transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth.
Figure 3-16 shows the pin orientation of the female MII receptacle on the Fast Ethernet port.
The MII receptacle uses two 56 screw-type locks, called jackscrews, to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews that you fasten to the jackscrews on the MII connector and tighten with your fingers. Use the jackscrews to secure your MII cable to the MII receptacle.
Table 3-4 lists the pinouts and signals for the I/O controller MII receptacle.

Following are the procedures for connecting AC-input and DC-input power to your Cisco uBR7200 series universal broadband router.
|
Warning Care must be given to connecting units to the supply circuit so that wiring is not overloaded. |
|
Warning Read the installation instructions before you connect the system to its power source. |
|
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. |
|
Note Detailed instructions for handling and replacing the Cisco uBR7200 series power supplies are contained in the documents Cisco uBR7200 Series 550-Watt AC-Input Power Supply Replacement Instructions (Cisco document number 78-4848-05) and Cisco uBR7200 Series 550-Watt DC-Input Power Supply Replacement Instructions (Cisco document number 78-5358-03). These documents accompany each power supply that is shipped from the factory as a FRU. These documents are also available on the Documentation CD-ROM and on Cisco Connection Online (CCO). |
If you have an AC-input power supply installed, proceed to the following section, "AC-Input Power Supply." If you have a DC-input power supply installed, proceed to the "DC-Input Power Supply" section.
|
Warning The device is designed to work with TN power systems. |
Step 2 Slide the cable-retention clip to the left, away from the AC receptacle, and plug in the power cable.
Step 3 Secure the cable in the power supply AC receptacle by sliding the cable-retention clip to the right until it fits around the connector. The cable-retention clip provides strain relief for the AC power cable. (See Figure 3-17.)
|
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 into the AC power source.
Step 5 Repeat Step 1 through Step 4 for the second power supply (if present).
This completes the procedure for connecting AC-input power. Proceed to the "Powering On the Cisco uBR7200 Series" section.
|
Warning When installing the unit, the ground connection must always be made first and disconnected last. |
|
Warning Secure all power cabling when installing this unit to avoid disturbing field-wiring connections. |
|
Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. |
|
Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground, black is used for +48V (return), and red or white is used for -48V. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source. |
Step 2 At the rear of the router, check that the power switch on the power supply is in the OFF (0) position.
Step 3 Connect the two-hole grounding lug on the grounding lead to the M5 grounding receptacles with the two M5 nuts. Tighten the nuts using an 8-mm wrench or nut driver (or adjustable wrench). (See Figure 3-19.)
|
Note Figure 3-20 shows the grounding lug connected to the two vertically-aligned M5 grounding receptacles. You can also connect the grounding lug to the two horizontally-aligned M5 receptacles. |
Step 4 Using a wire stripper, strip approximately 0.55 inch (14 mm) from the -48V and +48V leads. (See Figure 3-18.)
Step 5 Insert the stripped end of the +48V lead all the way into the +48V lead receptacle and tighten the receptacle screw using the same 3/16-inch flat-blade screwdriver. Repeat for the -48V lead.
|
Tips Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 4 through Step 5. |
Step 6 After tightening the receptacle screws and nuts for the ground, +48V, and -48V DC-input leads, run the +48V and -48V leads between the two strain-relief studs on the power supply faceplate. (See Figure 3-20.)
Step 7 Replace the strain-relief cover over the +48V and -48V leads and secure the cover to the strain-relief studs using the two M4 nuts with a 7-mm wrench or nut driver (or adjustable wrench). (See Figure 3-20.)
Step 8 Connect the ground, +48V, and -48V leads to the power source.
|
Note Each DC-input power supply has an electrical current rating of 14A, 700 VA. Use a minimum of 12 AWG (4 mm2) wire for the input to each DC-input power supply. The power input must be protected by a 20A circuit breaker or fuse that is in compliance with your local electric regulations. |
This completes the procedure for connecting DC-input power. Proceed to the following section, "Powering On the Cisco uBR7200 Series" to start the universal broadband router.
After installing your Cisco uBR7200 series universal broadband router and connecting cables, power on the universal broadband router as follows:
|
Tips If the port adapters, cable modem cards, network processing engine, or I/O controller are not properly seated or not fully locked into place, the Cisco uBR7200 series might enter a continuous restart loop. Make sure the boards are seated and locked into position. |
Step 2 At the rear of the Cisco uBR7200 series, place the power switch on the power supply in the ON (|) position. Repeat this step if a second power supply is installed. The green OK LED on the power supply goes on.
Step 3 Listen for the fans; you should immediately hear them operating. In a very noisy environment, also look for air movement around the chassis to verify that the fans are operating. If the Cisco uBR7200 series was recently switched off, it might take up to 90 seconds for the power supply to restart and the fans to start operating.
|
Note To facilitate headend installation, a Cisco uBR7200 series universal broadband router equipped with at least one cable modem card will generate a downstream IF carrier when it starts running. The downstream IF carrier will be present if a cable modem card is properly installed and passes diagnostics, the router has been powered on for more than two minutes, the IF downstream shutdown command (no cable downstream if-output) has not been configured, or the Cisco uBR7200 series is not in ROMMON mode. The amplitude and shape of the downstream IF carrier will not change after the Cisco uBR7200 series is configured, unless a non-DOCSIS data rate is configured. |
Step 4 During the boot process, observe the system LEDs. The LEDs on most of the port adapters go on and off in an irregular sequence. Some may go on, go out, and go on again for a short time. On the I/O controller, the IO power OK LED goes on immediately.
Step 5 Observe the initialization process. When the system boot is complete (a few seconds), the network processing engine begins to initialize the port adapter, cable modem cards, and the I/O controller. During this initialization, the LEDs on each port adapter behave differently (most flash on and off). The enabled LED on each port adapter and cable modem card goes on when initialization is complete, and the console screen displays a script and system banner similar to the following:
Cisco Internetwork Operating System Software IOS (tm) uBR7200 Software (uBR7200-I-M), Version 12.0(5)T [smith 100] Copyright (c) 1986-1999 by cisco Systems, Inc. Compiled Mon 12-Jul-99 04:10 by smith
Step 6 Configure the interfaces.
When you start up the Cisco uBR7200 series for the first time, the system automatically enters the setup command facility (also called the system configuration dialog), which determines which port adapters and cable modem cards are installed. The setup facility prompts you for configuration information.
On the console terminal, after the system displays the system banner and hardware configuration, the following System Configuration Dialog prompt appears:
--- System Configuration Dialog ---At any point you may enter a questions mark `?' for help.Use ctrl-c to abort configuration dialof at any prompt.Default settings are in square brackets `[]'.continue with configuration dialog? [yes]:
You can proceed with the setup facility or exit from setup, using the command interface to configure global (system-wide) and interface-specific parameters.
|
Caution The setup facility currently excludes cable-specific configuration commands. Upstream ports, therefore, have a default state of "shutdown" after the setup facility is run. You must configure upstream parameters. Refer to the Cisco uBR7200 Series Universal Broadband Router Software Configuration Guide for additional instructions. |
You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.
