I have a HS-D2.0TGL/R5.
The unit starts up, powers down after 30 seconds and then DIAG blinks five times every 4 seconds.
When I start it in EM mode by pressing the Init button, it comes up with only the "Diag" and "Power" blinking, but not "Link/Act". There is no network connectivity, although the port is powered.
Does it makes sense to try the steps under http://buffalo.nas-central.org/wiki/Ter ... _not_Start
in cases where the unit display a flash error in addition to the network not coming up?
