If either blower speed is below the Healthy Threshold, there is a blower
malfunction. See “Chapter 6: Maintenance” on page215.

Voltage Sensors

There are three power supply circuits inside the VTrak.
• Voltage Sensor – Circuits: 3.3V, 5.0V, 12V
• Healthy Threshold – Normal voltage range for each circuit
• Current Voltage – Should be within the Healthy Threshold values
If any voltage is outside the Healthy Threshold values, there is a voltage
malfunction in the enclosure. See “Chapter 8: Troubleshooting” on page 261.

Temperature Sensors

The number and type of sensors depends on the VTrak model. Controller
sensors normally run warmer than backplane sensors.
• Sensor number
• Location – Backplane or Control ler
• Healthy Threshold – Maximum acceptable temperatures.
• Current Temperature – Should be less than the Healthy Threshold
value.
If any temperature exceeds the Healthy Threshold value, there is an overheat
condition in the enclosure. See “Chapter 8: Troubleshooting” on page 261.
Enclosure Settings
Enclosure settings include internal sensor polling intervals and temperature
thresholds. To access Enclosure settings:
1. From the Main Menu, highlight Subsystem Management and press Enter.
2. Highli ght Enclosure Management and press Enter.
3. Highli ght Enclosure Settings and press Enter.
From this point, you can make settings to the polling interval and
temperature thresholds.

Polling Interval

Polling interval refers to the interval of time at which the Controller polls the
Enclosure temperature sensors and reports their values.
To make polling interval settings:
1. Highli ght Polling Interval and press the backspace key to erase the c urrent
value.
2. Type a new interval value in seconds.
15 to 255 seconds (4 minutes, 15 seconds)
