Blinks every second to indicate the ip.buffer is
functioning normally
●
E: Error
Blinks when booting. Normally off
Firmware 2.76 and above: The “S” green LED will blink at least every second
to show the ip.buffer is running. When any data arrives, the “S” green LED
will blink more rapidly
Firmware 2.75 and below: All LEDs (except the “L” LAN) will flash on, then off
every 8 seconds to show that the operating system kernel is functioning. The
LAN LED is controlled directly by the Ethernet circuitry.
1
When the ip.buffer boots up, the Modem LED will flash if there is a modem present. If no modem
is installed, the Modem LED will not light (except for the regular 8 second flash)
2
This 'quieter' LED display was introduced because there was some confusion over the 8-second
flash and end users thought the red “E” LED was indicating something!
