Hi,

reset-procedure:

In case you have a static-ip configured nanoBTS or other inconvenience with
the nanoBTS ... just use the reset-dongle.
The reset-dongle is a plug for the TIB-IN with short 9+10.
The reset procedure is as follows:
Power off
Reset-dongle in TIB-IN
Power on
Wait until the light is flashing red (30 sec.)
Power off
When you are now starting the nanoBTS the light will flash red/green to tell
you there is no ID set.
Find the ip now by ipaccess-find eth0
Set the ID by ipaccess-config -u 1/0/0 999.999.999.999
The 999.999.999.999 is for the ip :-)

As suggested by you and Chris, I have patiently shorted 9+10 and the light started to blink RED. Subsequently I have turned off the bts and removed the shortcircuit.
However, after turning it on again, the situation is always on ORANGE stable/not blinking light.

Right now I am reading the manual and it says:
"LED_SELF_TEST, Orange Steady, From power on until end of backhaul power on self-test"

I am wondering what else could be the problem. Maybe the MacGyver's way to short-circuit didn't work properly. (I am going to look for a proper RJ-69)

I have also noticed that if I don't plug it into the router, the BTS shows a RED stable/not blinking light.
And as the manual says, it could be a bad sign (I guess):

"LED_SELF_TEST_FAILURE, Red Steady, In boot or application code when a power on self-test fails.

LED_UNSPECIFIED_FAILURE, Red Steady, On s/w fatal errors."

If you have other suggestions will be appreciated. Thanks.

Cheers,
Luca

P.S. Just to be precise, I have followed the standard pin numeration to find the 9-10 pins ( http://quatech.com/products/images/rj45_sds.gif )
