Initial Configuration

This chapter guides you through a basic router configuration, which is sufficient for you to access your network. Complex configuration procedures are beyond the scope of this publication and can be found in the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

To configure a Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router from a console, connect a terminal to the router console port.

Checking Conditions Prior to System Startup

Ensure that the following conditions are addressed before starting up the router:

  • The optional Gigabit Ethernet Management port cable is installed.
  • The chassis is securely mounted and grounded.
  • The power and interface cables are connected.
  • Your PC with terminal emulation program (HyperTerminal or equivalent) is connected to the console port and powered up.
  • Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop-bit, no parity, and no flow control is set to none.
  • You have selected passwords for access control.
  • Captive installation screws are tight on all the removable components.
  • The console terminal is turned on.
  • You have determined the IP addresses for the Ethernet and serial interfaces.

Powering Up the Router

After installing your Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router and connecting cables, start the router and follow these steps:

Procedure

Step 1

Switch on the power supply.

Caution

 

Do not press any keys on the keyboard until the messages stop and the PWR LED is solid green. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to power off and start over. It takes a few minutes for the messages to stop.

Step 2

Observe the initialization process. When the system boot is complete (the process can take a few minutes), the Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router begins to initialize.

Checking the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-config command at the Router# prompt: 


Router# show running-config

To review the changes you have made to the configuration use the show startup-config command in the user EXEC mode to see the changes and copy run-start stored in the NVRAM.

Saving the Running Configuration to NVRAM

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-config startup-config command at the prompt:

Router# copy running-config startup-config

Using this command saves the configuration settings that you created in the router using the configuration mode and the setup facility. If you fail to do this, your configuration will be lost, and will not be available when you reload the router next.

Automatic Shutdown of the Router

This section lists the scenarios in which the Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router shutdown is automatically initiated by software:

  1. After removal, fan tray is not re-inserted back within stipulated time period. For more information on shutdown time, see Cisco ASR-920-24SZ-IM Router Shut Down Time Table.
  2. The on-board or the PSU temperature sensors detect the shutdown limit.
  3. Multiple fan failures (two or more than two) fans fail.

After the router shutdown, the PSU LED turns red to indicate that the PSU is switched off.
