Monitoring the Physical Environment of the Router

Purpose

Display information about the router’s physical environment, such as voltage or temperature. The system displays a message if the voltage or temperature exceeds normal operating limits. The system enters thermal protection mode if the temperature exceeds maximum operating limits or if the fan system on the E120 and E320 routers reports a critical error. For information about thermal protection mode on ERX7xx models, ERX14xx models, and the ERX310 router, see the Troubleshooting chapter in the ERX Hardware Guide. For information about thermal protection mode on the E120 and E320 routers, see the Troubleshooting chapter in the E120 and E320 Hardware Guide.

Optionally, you can specify the all keyword to view both the system environment information and the detailed temperature status table, or specify the table keyword to view only the temperature status table.
