Initial Power Up

Upon initial power up, all the front panel LEDs blink simultaneously. They blink once for
multimode or twice for singlemode. Afterwards, the LEDs return to their normal signal
presence indication.
If a different fiber optic SFP module or no SFP module is connected, the LEDs first blink
once or twice to identify the device, but then blink continuously.

1. Press the input selection button that corresponds with the desired rear panel input
connector.
2. The corresponding LED lights to indicate the active input.
