Echelon MPR-50 Multi-Port Router - Manual (Page 16)

LED Legends
The Power LED will illuminate whenever power is connected to the MPR-50.
The following two tables describe the behavior of the Status LEDs for the Monitor
and for Routers 1–5. For easy reference, shortened versions of the Status LED
legends are printed on the front panel of the MPR-50.
The Status LEDs illuminate as green, orange, and yellow. When yellow is displayed,
orange and green may appear illuminated together depending upon the lighting
conditions.
