LEDs on the Board
On the WPJ344 and WPJ342 boards, the LEDs starting from the one nearest the corner are: Power, LAN, LED#1, LED#2, LED#3, and LED#4.
LED Configuration for Signal Strength Indicator LEDs #1 to #4
The System ➤ LED Configuration page customizes how the LEDs indicate the received signal strength.
Signal strength indicator interface: Chooses the Wireless interface, which is the wireless network name.
Signal strength indicator LEDs: Sets the received signal strength thresholds (in dBm) above which LEDs #1 to #4 would light up.
Summary of the LED Indicators
The LED indicators are summarized in the following table.
|Power (green)||The Power LED emits a steady light when electrical power (normally at 24 V) is supplied to the board.|
|LAN (green)||The LAN/Diagnostic LED is lighted dimly when the LAN ports are not connected.
The LAN LED blinks whenever packets are transferred through any of the LAN ports.
|LED#1 (red)||LED#1 indicates the received signal strength (low).|
|LED#2 (orange)||LED#2 indicates the received signal strength (medium).|
|LED#3 (green)||LED#3 indicates the received signal strength (high).|
|LED#4 (green)||LED#4 indicates the received signal strength (very high).|
When the board is in the Loader mode, this LED#4 blinks steadily. LEDs #1 to #3 are not lighted up. Note: The physical arrangement of LEDs on the board may differ for different models.
