    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
        Temperatures  Chassis:1   
        
        Module      Sensor                  Measurement   
        ---------   ---------------------   -------------   
        amp:1/4     DS75 Temp 1             33 deg C   
        amp:1/4     DS75 Temp 3             48 deg C   
        amp:1/4     LM84BIQA Temp           33 deg C   
        amp:1/4     Line card Temp          49 deg C   
        bic:1/1/1   BIC Temp                63 deg C   
        bic:1/1/1   DS75 Temp BIC A         40 deg C   
        bic:1/1/2   BIC Temp                50 deg C   
        bic:1/1/2   DS75 Temp BIC B         34 deg C 
      2. To show the readings for the fan speed sensors on the cooling units:

        For example:

        bti7800# show environment fanspeed
        Fan Speed  Chassis:1   
        
        Module      Sensor                  Measurement   
        ---------   ---------------------   -------------   
        fan:1/1     Fan RPM                 5080 rpm(97%)   
        fan:1/2     Fan RPM                 5160 rpm(99%)   
        fan:1/3     Fan RPM                 5200 rpm(100%)   
        fan:1/4     Fan RPM                 5160 rpm(99%) 

        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
        Power  Chassis:1   
        
        Module      Sensor                  Measurement   
        ---------   ---------------------   -------------   
        pem:1/1     PEM AC A1 Power         Power Present   
        pem:1/2     PEM AC A2 Power         Power Present   
        pem:1/3     PEM AC B1 Power         Power Present   
        pem:1/4     PEM AC B2 Power         Power Present 
      4. To show the readings for the voltage sensors on all modules:

        For example (output truncated for clarity):

        bti7800# show environment voltage
        Voltages  Chassis:1   
        
        Module      Sensor                  Measurement
