Appendix C: MPX Status LEDs

MPX1000 receivers and all MPX1500 products feature five front-panel LEDs that are used to
convey state and status information. The following diagram illustrates the order and color of the
LEDs:

Figure C.1: MPX LED Status Indicators

LED sequences convey operational states and status of the receiver. The following sections define
the key LED sequences of the product.
NOTE: When a LED is described as Flashing, it is flashing on and off at a rate of 4 flashes per second. When a
LED is described as Blinking, it is blinking on and off at a slower rate of 1.5 seconds per blink. When a LED is
described as On Solid, it is continuously illuminated and is neither blinking nor flashing.
Power-on initialization status
During system initialization, the LEDs will turn on from left to right until all LEDs are on. Then,
the LEDs will turn off from right to left until all LEDs are off. This pattern will repeat throughout
the system initialization process.
If a Power On Self Test (POST) error occurs, a specific pattern will be displayed. Please make note
of the pattern prior to contacting Avocent technical support.
Wireless operation status
If no connection exists, a 2-step searching pattern sequence is displayed, as follows:
Search pattern: Green-1 and Green-2 will alternate, all other LEDs remain off.
If a connection does exist, MPX1500 transmitters will illuminate all 5 front-panel LEDs.
If a connection does exist, MPX receivers display the current signal level (0-5) by the LEDs.
Higher numbers indicate stronger signals. The following table correlates LED patterns to signal
strength:
LED 5: Green-2
LED 4: Green-1
LED 3: Amber-2
LED 2: Amber-1
LED 1: Red
