Maintaining the MX2010 Routing Engines
Purpose
Each host subsystem comprises a Control Board and Routing Engine (CB-RE) functioning together.
To maintain the host subsystem, check the LEDs (RE0 and RE1) on the craft interface. For more information
about the LEDs and the display, see “MX2010 Craft Interface Description” on page 29 .
NOTE: Even though the Routing Engine is combined with a Control Board (CB-RE), separate
LEDs on the craft interface show the status of the Routing Engines, and separate LEDs show
the status of the Control Boards.
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 “MX2010 Craft Interface Description” on page 29 . During normal operations:
NOTE: Even though the Routing Engine is combined with a Control Board (CB-RE), separate
LEDs on the craft interface show the status of the Routing Engines, and separate LEDs show
