Maintaining Host Module Components

The router can have a Routing Engine in each of the slots labeled RE 0 and RE 1 and a Miscellaneous Control Subsystem (MCS) in each of the slots labeled MCS 0 and MCS 1 at the rear of the chassis, as shown in Figure 3. Each paired Routing Engine and MCS function together as a host module. To maintain the host module, perform the following procedures regularly:

Check the LCD and the host module LEDs on the craft interface. The LCD reports host module status during normal operation and describes the cause of failures when they occur. The green LEDs labeled ONLINE and MASTER light steadily for the master host module when it is functioning normally. The ONLINE LED also lights for the standby host module if it is installed. For more information about the LEDs and LCD, see Craft Interface on page 27.

Issue the CLI show chassis routing-enginecommand to check the status of the Routing Engines. As shown in the sample output, the master Routing Engine is designated Master in the Current state field:
