7 Managing the device
If an I2C failure has not occurred, there will be no I2C messages in the static log, dynamic log, or SNMP log server. The following example shows output from the show logging command when there is no I2C failure.

If the system detects a major I2C failure, the system prevents the management module from accessing devices through the l2C serial bus. The output from the show chassis command and the show temperature command reflect this action, as shown in these examples.

Displaying device status and temperature readings
You can display the following information about the router:
•
•Status of the fans
•Temperature readings of the management, switch fabric, interface, and fan control modules and the interval at which the system reads the temperature of these modules
•MAC address of the device
