AS-P Server LEDs
There are several LEDs on the front panel of an AS-P server.
The AS-P server comes in different models. The AS-P and AS-P-S models have nine LEDs whereas the AS-P-NL and AS-P-NLS models have seven LEDs.

Status (AS-P server) |
Green/Red |
- The AS-P server models AS-P-NL and AS-P-NLS do not have LEDs for LonWorks (LON).
The AS-P server Ethernet and Status indicators comprise two LEDs (green/yellow and green/red respectively) in one structure. Normally, when one LED is lit, the other is not lit and vice versa, that is, the indicator will show one color at a time.
The LEDs indicate status of the AS-P server and the ongoing communication.
Status LED
The AS-P and AS-B server Status LED indicates the condition of the device.
