Network Activity LED (1) — This LED flashes to indicate activity on the first network.
Network Activity LED (2) — This LED flashes to indicate activity on the second network.
Overheat and Fan Failure LED — When this LED is flashing, it indicates that a fan has failed inside the recorder. When the LED is continuously lit, it indicates that the recorder has achieved a condition which may cause it to overheat. This LED will remain flashing or on for as long as these conditions exist.
NOTE: | If the LED is continuously lit, the condition may be caused by cables |
obstructing the airflow of the recorder or the ambient room temperature. | |
Check the routing of the cables and make sure all fans are operating | |
normally. If necessary, move the recorder to a cooler location or adjust the | |
room temperature. | |
zz Power Supply/Fan Failure LED — When this LED is lit, it indicates a power supply fan has failed. The power supply module has a redundant backup fan that will increase its speed to compensate, but the power module should be replaced as soon as possible.
NOTE: | The recorder may operate louder than usual until the power supply is |
replaced. | |
EUSB (Universal Serial Bus) ports — Insert any compatible USB device into these ports. Use an external USB storage device with these ports to update the system.
