"D-link 5 Port Ethernet Switch Not Working"
14 February 2013
Summary: the power adapter is bad.
Have 2 D-link 5 port Ethernet Smart Switches.
Suddenly, although the "power" light emitting diode (LED) is lit, there is no Ethernet transfer through the switch.
No LED's lit on any of the 5 managed Ethernet ports.
The power adapter for this switch provides 5 volts 1.2amperes (amps).
I have had 2 adapters go bad.
New adapter, switch works correctly.
New or used adapters can be found on Amazon or eBay websites.
Below is the inside of the D-Link AF0605-B 5volt 1.2 amperes power adapter/
Although not clear on this picture, the one green capacitor is bulging at the top, which means it is bad.
Probably a $.25 part but whole module is a throw away.
Probably a design issue or poor quality control on capacitors.
