The green LED H801
“POWER” indicates that power is connected. This LED is on if the board
is active and off if the SHDSL.EVB.4CH is not powered up.
The four green LEDs H501 - H505 signaling the status of the SHDSL lines. The LED is off if
SHDSL is not active (e.g. during initialization). If the SHDSL chipset is initialized, the LED
blinks slowly (approximately 1Hz). The SHDSL chipset is ready to work and waits for detecting
counterpart station. Once the counterpart station is detected, the training process starts and
the LED blinks faster (approximately 3 Hz). This process takes some seconds and if the
SHDSL chipset can establish a SHDSL link the LED stops blinking.
The state of the Ethernet port is indicated by the green LED H301 and the amber LED H302.
The LEDs are off
if the Ethernet PHY hasn’t detected any Ethernet counterpart. The green
LED goes on if an Ethernet link is established. The amber LED starts blinking if data
transmission is active.
The amber blinking LED H505 (“STATE”) shows the normal status of the SHDSL.EVB.4CH. If
the amber LED stops blinking or switch off a software error has occurred. In this case the
software Watchdog will be resetting the board after 30 seconds.
A red LED H506
(“ERROR”) indicates an error state. For normal operation this LED is off. The
LED is on or starts blinking if an error has occurred. The error type will also print to the serial
interface (USB UART emulation and hardware UART).
