State | Meaning
--- | ---
Off | The unit is not plugged in or not powered on. To turn the unit off, touch the power button. To save energy, the unit turns off automatically when idle for 30 minutes. Note: Turning the unit off or removing a smart card does not affect users' sessions.
Green | The unit is powered on and is functioning normally. When the unit is first plugged in, it turns on automatically. To turn the unit on manually, touch the power button, located below the LED, or insert a smart card.
Amber | The LED lights for 2-3 seconds or less at power-on while the unit performs diagnostic tests. If the LED remains amber or becomes amber at any other time, the unit may be inoperable and should be reset. To reset the unit, power off and power on the unit by using the power button or by unplugging and replugging the power cord. If the LED remains amber, continue to reset the unit two more times. If the LED remains amber after three resets, the unit is inoperable. Contact your system administrator to replace the unit.
