Maintaining the T1600 Routing Engines

Purpose

For optimum router performance, verify the condition of the routing engines and the control boards.

Action

On a regular basis:

• Check the host subsystem LEDs on the craft interface. For more information about the LEDs and the display, see T1600 Craft Interface Description.
• Check the LCD on the craft interface to view information about the router temperature and the status of the Routing Engines.
• Issue the show chassis routing-engine command to check the status of the Routing Engines. The output is similar to the following:
  
  

  user@host> show chassis routing-engine
