Indicators for device powering up
When the device is powering up, the following LEDs light up in the sequence
shown:
1. Power LEDs (L) light up as soon as voltage is present.
2. Port LEDs (P1...P6) light up yellow for around 6 s.
3. Port LEDs go out. Once the port LEDs have gone out, the correct link status is
displayed after around 2 s.
4. The red fault LED lights up for around 20 s.
The FN2008-A1 is then ready.
