Starting the iNS
When the iNS is powered up, the LEDs will flash to indicate normal operation. The
following LED colors and patterns will be displayed during normal startup, if no errors are
detected.
•
Status LED – initially this LED will be yellow, but will quickly turn green. If the status
LED is solid green, then the iNS doesn’t have a permanent IP address and is trying to
obtain one from a DHCP server. If the LED is blinking green, it means the iNS has
obtained an IP address and is ready to use. Red indicates a fatal error.
•
Ethernet LEDs – these LEDs will either be off or green. A green LED means that a good
Ethernet link has been established and the unit is on the network. The LED will blink
green to show network activity.
•
Serial port LEDs – these LEDs will normally be either off or green. Off indicates a port
that is not in use. Green indicates a port that is in use. The green LED will blink when
data is transmitted or received. It will blink 2 times per second when data is
continuously transmitted or received.
If any of the LEDs turn red, an error condition was detected. For a full description of the
LED patterns, see Troubleshooting.
