(To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.)
  • Page 5: Safety With Electricity

    Safety Recommendations Network hazardous voltages are present in the BRI cable. If you detach the BRI cable, Warning detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned off.

  • Page 17: Configuring T1 Interfaces

    To configure a PRI interface, you must use configuration mode (manual configuration). In this mode, you enter Cisco Internetwork Operating System (Cisco IOS) commands at the router prompt. The following sections explain how to configure PRI interfaces. Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process.
  • Page 18 Router(config)# ip routing Router(config)# appletalk routing Router(config)# ipx routing For complete information about global configuration commands, refer to the Cisco IOS configuration guides and command references. Enter the controller t1 command to select the CT1/PRI interface to configure. For Step 6 example, to configure a T1 interface in slot 1 and unit 0, enter the following command:...
  • Page 19 Router(config-if)# Add any configuration commands needed to enable routing protocols or adjust the Step 13 interface characteristics. Refer to the Cisco IOS configuration guides and command references for more information. Step 14 If your router has more than one CT1/PRI interface, enter the exit command to return to the Router(config)# prompt.
  • Page 20: Configuring E1 Interfaces

    Configuring the PRI Interfaces The results of the show running-config and show startup-config commands differ from Step 17 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 command copy running-config startup-config at the enable prompt: Router# copy running-config startup-config Building configuration.
  • Page 21 Router(config)# ip routing Router(config)# appletalk routing Router(config)# ipx routing For complete information about global configuration commands, refer to the Cisco IOS configuration guides and command references. Step 6 Enter the controller e1 command to select the CE1/PRI interface to configure. For example, to configure an E1 interface in slot 1 and unit 0, enter the following command:...
