LED INDICATORS(VESR90X)
VESR9xx Serial Servers have three LED indicators: a
Link LED
, a
Ready LED
and two
Serial Port
LEDs
.
LEDs on 1 and 2 Port Serial Servers
LINK LED
The
Link
LED illuminates (green) if the Ethernet connection is operating in 100BaseTX
mode. The LED is off if the mode is 10BaseT. When the LED is blinking it indicates
that there is data traffic on the Ethernet link.
READY LED
The
Ready
LED (green) blinks once per second if the system is operating correctly. If
the LED is off, it indicates the system is not operating correctly.
SERIAL PORT LEDS
VESR901-x serial servers feature one serial port. VESR902D,and VESR902T-x serial
servers feature two serial ports. Each serial port has an associated LED. Serial Port
LEDs blink (green) when data is being transmitted or received on the serial port.
When the LED is On it indicates the serial port is open.
