Operation- LED Indicators, Port Connected LED’s

Section 3: Operation- LED Indicators

LED Indicators- When the power is switched “on”, all of the LED’s light briefly and then the PORT LED’s sequence through two patterns. The LED’s then resume normal operation. The LED functions are described below.

POWER LED-

This indicator illuminates when the CM16a power switch is in the “on” position.

DIAGNOSTIC LED-

NETWORK STATUS LED’s-

PORT CONNECTED LED’s-

This indicator illuminates during the power-on self test, then should turn off. If it remains illuminated, this indicates that the self-test has detected an unexpected event, such as a corrupted firmware update via TFTP or a memory boot failure. If the DIAGNOSTIC LED remains illuminated, try resetting the CM16a by cycling power off and on once. Should the indication persist, contact QSC’s Technical Services for guidance.

There are three LED’s on the front and rear panels labeled RCV, XMT and LINK STATUS. Their functions are described below.

RCV- This LED lights up any time the CM16a receives data over the network.

XMT- This LED lights up whenever the CM16a transmits data over the network.

LINK STATUS- When lit, this LED indicates that the CM16a is connected to an operating Ethernet network.

If not lit, there is most likely a cabling problem between the CM16a and the hub or possibly a fault in the hub.

These LED’s are labeled PORT A through PORT H on the front panel. The respective LED will illuminate when functional connection has been made between the CM16a and an amplifier. The amplifier’s power does not have to be ON in order for the LED to indicate successful connection.
