Hard to be specific if I want to know ALL the LED state meanings.
Examples that seem to be missing or incorrect:
1) I've got AP335's where the system status LED is amber. The IAP install doc doesn't list any amber state for the system LED.
-> this appears to be on 100Mbps links
2) which then contradicts the install guide as Green flashing should be uplink < 1Gbps or non-HT radio (which is weird too: why a radio state on the system led?)
3) our AP335 system LED is flashing for (pretty much?) all our deployed APs even though they are connected at 1Gbps and both radio's have HT enabled.
