This section outlines important LED error conditions on the Fiberlink NNI Receiver unit.
•Fast Blink — All LEDs on the Fiberlink NNI Receiver blink fast if more than 1.5
amps of current are drawn from the unit by the NNI LED wall. In this condition, the
power from the Receiver to the wall is shut down.
•Slow Blink — All LEDs on the Fiberlink NNI Receiver blink slow if more than .75
amps of current are drawn from the unit by the NNI LED wall. In this condition, the
power from the Receiver to the wall is shut down.
Each “blinking” condition points to a power supply, connection, or other power-related error
on one or more NNI wall tiles.
Important An NNI cable is a High Definition Multimedia Interface (HDMI)
cable. You should not attempt to connect an NNI cable to an
HDMI monitor. Connecting directly to a monitor can result in
damage to the monitor.
Important Always put the dust cap on securely when the NNI cable is
not connected to the unit. The dust cap is secure when it
clicks into place.
