3.2.2. Status LED’s
The One-Net's two LED’s are used for a variety of status indications, making
it easy to see at a glance certain important system states.
System Status - Green LED
•
When the One-Net is first powered on, the green LED is dark.
•
When the booting process advances far enough, the green LED begins to
blink.
•
When the One-Net nears a ready state, the green LED blinks more rapidly.
When the One-Net is ready, the green LED light is on solid. A solid green
LED indicates the One-Net is operational.
•
If the green LED starts blinking, the One-Net server has become non-
operational. This can happen during software upgrades.
Alert status - Red LED
•
When the One-Net is first powered on, the red LED is dark.
•
After the One-Net becomes operational, in a ready state, with the green
LED solid, the red LED indicates decoding and alert sending status.
•
If the red LED is blinking quickly, with pauses, the One-Net server is
decoding an incoming alert. If the red LED is solid, the One-Net is
sending an EAS alert.
3.3. Back Panel Connectors
The back of the One-Net provides all of the connection ports. In addition to the
standard PS/2 mouse and keyboard and VGA monitor ports, the One-Net provides an
RS-232 serial port (COM1), a parallel port, an RJ45 LAN port, two USB ports, main
audio line in, out, and microphone jacks, auxiliary audio line in, out, and microphone
jacks, and a TV out connector (Yellow RCA jack).
