Monitoring Environmental Sensors

 

Use this procedure to display environmental measurements such as fan speed and system temperature.

The BTI7800 has sensors deployed in various locations on the chassis. By periodically examining these sensor readings, you can monitor the overall health of the system.

You can display all readings or readings for a particular type of sensor.

  1. To display all readings:
    bti7800# show environment
  2. To display readings for a specific type of sensor:
    1. To show the readings for the temperature sensors on all modules:

      For example (output truncated for clarity):

      bti7800# show environment temperature
    2. To show the readings for the fan speed sensors on the cooling units:

      For example:

      bti7800# show environment fanspeed
      Note

      The RPM measurement shown for either a BTI7814 Booster Fan (BT8A78FAN9) or a 2-Slot Chassis Cooling Module (BT8A78FAN2) is an average of the RPM values of the individual fans in the cooling module.

    3. To show the readings for the power sensors on the PEMs:

      For example:

      bti7800# show environment power
    4. To show the readings for the voltage sensors on all modules:

      For example (output truncated for clarity):

      bti7800# show environment voltage
    5. To show the readings for the current sensors on the BTI7814 AC PEMs:

      For example:

      bti7800# show environment current
