The following warnings apply when you are installing a card or working with the power supply:
 |
Warning Read the installation instructions before you connect the system to its power source. |
|
Warning Only trained and qualified personnel should be allowed to install or replace this equipment. |
|
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
|
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. |
|
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. |
The following warnings apply when you are working with electricity:
|
Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
|
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Both LAN and WAN ports may use RJ-45 connectors. Use caution when connecting cables. |
|
Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. |
|
Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
|
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. |
Follow these guidelines when working on equipment powered by electricity:
If an electrical accident occurs, proceed as follows:
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur when printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To guard against ESD damage and shocks, the wrist strap and cord must be used properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
 |
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm). |
For this connection, use the standard lavender RJ-11 cable that came with your card.
 |
Note If you are connecting a 1700 series router with an ADSL card to an RJ-11 wall jack that has the ADSL pair wired for pins 2 and 5, you must use the lavender crossover cable with the blue stripe. The crossover cable is orderable as a spare. |
The following steps describe how to connect the card with the standard lavender RJ-11 cable but also apply to the lavender crossover cable with the blue stripe.
Step 2 Connect one end of the cable (RJ-11) to the ADSL port on the card.
Step 3 Connect the other end of the cable to the wall jack (RJ-11) at your site, as shown in Figure 4.
Step 4 Turn on power to the router.
The following warning applies to routers that use a DC power supply:
|
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. |
Step 5 To connect the card to the network, you must configure the ADSL card in the router to the no shutdown state. Enter the no shut command in the router configuration. Verify that the CD LED goes on, indicating that the card is connected to the network.
Whenever you install a new WAN interface card, or if you want to change the configuration of an existing interface, you must configure the interface. If you replace a card that was already configured, the router recognizes it and brings up the interface in the existing configuration.
Before you configure an interface, have the following information available:
 |
TimeSaver Obtain this information from your system administrator or network plan before you begin router configuration. |
You can configure the new interface and other router parameters by using any of the following methods:
These procedures are explained in the following sections. To change the settings shown in the examples, and for further information, refer to the IOS configuration guides and command references. If you have questions or need help, refer to the section "Obtaining Technical Assistance" later in this document.
The IOS software provides the following default configurations for ADSL-specific parameters. The following default command sets the ADSL operating mode:
dsl operating-mode auto
The following default command sets the ATM vc-per-vp configuration for the router:
atm vc-per-vp
The following default command shows the ADSL WIC information:
show dsl interface atm [0 or 1]
The following default command shows the internal driver information on the ADSL WIC:
show controller atm [0 or 1]
The following default command shows the current configuration:
show running-config
You can configure the interfaces on your ADSL WAN interface card manually by entering IOS commands on the command line. For further information about these commands, refer to the IOS configuration guides and command references.
This method, called configuration mode, provides the greatest power and flexibility.
Before you begin, disconnect all WAN cables from the router to keep it from running the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
To enter configuration mode, follow this procedure:
Step 2 If the current configuration is no longer valid, after about one minute you see the following prompt:
Would you like to enter the initial dialog? [yes]:
Enter no. You now enter the normal operating mode of the router.
|
Note If the current configuration is valid, you enter the normal operating mode automatically. |
Step 3 After a few seconds, you see the user EXEC prompt (Router>). Type enable and the password to enter enable mode:
Router> enable Password:
Configuration changes can be made only in enable mode. The prompt changes to the privileged EXEC (enable) prompt (Router#):
Router#
Step 4 Enter the config terminal command to enter configuration mode:
Router# config terminal Router(config)#
The router enters global configuration mode, indicated by the Router(config)# prompt.
Step 5 If you have not configured the router before or want to change the configuration, you can configure global parameters, passwords, network management, and routing protocols. In this example, IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing are all enabled:
Router(config)# ip routing Router(config)# appletalk routing Router(config)# ipx routing
For complete information about global configuration commands, refer to the IOS configuration guides and command references.
Step 6 Select the ADSL interface to configure:
Router(config)# interface atm 0 Router(config-if)#
The prompt changes again to show that you are in interface configuration mode.
Step 7 Configure routing protocols on the interface. (You must have previously enabled these protocols as part of global configuration.) In this example, IP, AppleTalk, and IPX are being configured on the ADSL interface:
Router(config-if)# ip address 1.10.16.16 255.255.0.0 Router(config-if)# appletalk static cable-range 5-5 Router(config-if)# appletalk zone ZZ Router(config-if)# ipx network B004
Step 8 To configure another interface, enter the exit command to return to the Router(config)# prompt. Repeat Step 6 through Step 8 of this procedure to configure the next interface.
Step 9 When you finish configuring interfaces, exit configuration mode and return to the enable prompt by pressing Ctrl-Z. To see the current operating configuration, including any changes you just made, enter the show running-config command:
Router# show running-config
To see the configuration currently stored in NVRAM, enter the show startup-config command:
Router# show startup-config
Step 10 The results of the show running-config and show startup-config commands differ from each other if you have made changes to the configuration but have not yet written them to NVRAM. To write your changes to NVRAM, making them permanent, enter the copy running-config startup-config command:
Router# copy running-config startup-config Building configuration. . . [OK] Router#
The router is now configured to boot in the new configuration.
The AutoInstall process is designed to configure the router automatically after it connects to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be configured to provide the configuration files. The TCP/IP host can reside anywhere on the network if the following two conditions are met:
This functionality is coordinated by your system administrator at the TCP/IP host site. You should not try to use AutoInstall unless the required files are installed on the TCP/IP host.
Follow this procedure to prepare your router for the AutoInstall process:
Step 2 Turn on power to the router.
The router loads the operating system image from Flash memory. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process begins.
Step 3 If AutoInstall succeeds, you should write the configuration data to the router's NVRAM. To do this, enter the copy running-config startup-config command at the Router# prompt:
Router# copy running-config startup-config Building configuration. . . [OK] Router#
|
Note This step saves the configuration settings that the AutoInstall process created. If you do not do this, your new configuration will be lost the next time you boot the router. |
You can configure the router manually using the System Configuration dialog (also called the Setup facility). Unlike configuration mode, the System Configuration dialog prompts you for each response.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a configuration file stored in NVRAM. It can take several minutes for the router to determine that AutoInstall is not connected to a remote TCP/IP host.
This section shows a sample configuration using the System Configuration dialog. You should enter values appropriate for your router and network. To change the settings shown in the examples, and for further information, refer to the IOS configuration guides and command references.
Many prompts in the System Configuration dialog include default answers, shown in square brackets following the question. Enter your response, or press Return to accept the default answer.
You can request help at any time by entering a question mark (?) at the System Configuration dialog prompt.
Follow this procedure to configure the router using the System Configuration dialog:
Step 2 If the current configuration is no longer valid, after about one minute you see the following prompt:
Would you like to enter the initial dialog? [yes]:
Press Return or enter yes to enter the System Configuration dialog.
|
Note You can enter the System Configuration dialog at any time from the enable prompt (Router#) by entering the setup command. |
Step 3 When the System Configuration dialog asks whether you want to view the current interface summary, press Return or enter yes:
First, would you like to see the current interface summary? [yes]: yes Interface IP-Address OK? Method Status Protocol ATM0 unassigned NO unset down down ATM1 unassigned NO unset down down FastEthernet0 unassigned NO unset down down
Step 4 If you have not configured the router before, or want to change the configuration, you should now configure global parameters, passwords, network management, and routing protocols. Refer to the procedures in the IOS configuration guides and command references. Press Return if you want to accept the default values.
Step 5 The System Configuration dialog prompts you to configure network interfaces. When you reach the ADSL interface, determine which protocols you want on the interface and enter the appropriate responses. (You must have previously enabled these protocols as part of global configuration.) In the following example, the interface is being configured for IP, AppleTalk, and IPX:
Configuring ATM parameters
Do you want to configure ATM0 interface? [yes]: yes
Configure IP on this interface? [yes]:
IP address for this interface: 2.0.2.111
Subnet mask for this interface [255.0.0.0]: 255.255.0.0
Class A network is 2.0.0.0, 16 subnet bits; mask is /16
Do you want to configure ATM1 interface? [yes]: no
Do you want to configure FastEthernet interface? [yes]: yes
Using the 100 Base-TX (RJ-45) connector? [yes]:
Operate in full-duplex mode? [no]: yes
Configure IP on this interface? [yes]: yes
IP address for this interface: 1.10.16.16
Subnet mask for this interface [255.0.0.0] 255.255.0.0
Class A network is 1.0.0.0, 16 subnet bits; mask is /16
Step 6 If your router has more than one LAN interface, repeat Step 5 to configure the next LAN interface.
Step 7 The configuration you entered is displayed as a command script, and you are asked if you want to use it. If you enter no, the information you just entered is discarded and you can begin the configuration again. If you enter yes, the configuration is saved in the startup configuration:
Use this configuration? [yes/no]: yes Building configuration... Use the enabled mode 'configure' command to modify this configuration. Press RETURN to get started!
The configuration is saved. If you added an interface, the router reboots in the new configuration when you press Return.
You can configure the router for ATM and ADSL parameters using the following scenarios:
To configure the router for these scenarios, refer to the Cisco 827 Routers Software Configuration Guide. This guide contains both sample network scenarios and specific router configurations to set up data or voice networks for the ATM and ADSL interfaces.
You can also access the information online at the following location:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/827/index.htm.
The following example shows a 1700 series router configured for bridging on the ATM interface with an ADSL card:
Current configuration: ! version 12.1 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname meltrack ! no ip routing ! interface ATM0 no ip address atm vc-per-vp 256 pvc 8/35 encapsulation aal5snap ! dsl operating-mode auto bridge-group 1 ! interface FastEthernet0 no ip address speed auto bridge-group 1 ! ip classless no ip http server ! bridge 1 protocol ieee ! line con 0 transport input none line aux 0 line vty 0 4 login ! end
Most splitters must be installed by the telephone company; however, some splitters can be installed by the customer. If you are not sure what type of splitter to use, contact your service provider.
Figure 5 is an example of a type of POTS splitter that is installed at the customer premises by the customer. Other types of POTS splitters are installed by the telephone company on an exterior wall of the customer premises.
Microfilters are installed on telephones to improve voice-call quality when voice and data equipment are using the same telephone line (twisted pair). You should use microfilters with the Cisco 1700 series routers only when the two following conditions exist:
Figure 6 shows one type of microfilter.
This section describes the most common scenarios using splitters and microfilters with the Cisco 1700 series routers. The scenarios are listed from most common to least common.
This scenario is described below and illustrated in Figure 7.
This scenario is described below and illustrated in Figure 8.
This scenario is described below and illustrated in Figure 9.
