Ethernet port turned off after few minutes

Former Member
Former Member over 13 years ago

I am using 5V 1300mA adapter (http://www.skross.com/product/en/15/USB-Charger/56/World-USB-Charger.html) to power my Pi and another cheaper adapter that gives 5V 800mA.

 

The SD card is KINGSTON 16GB 100X SD10-HC.

 

I plugged in my Ethernet cable into the port and booted off Debian image from http://downloads.raspberrypi.org/images/debian/6/debian6-19-04-2012/debian6-19-04-2012.zip (SSH enabled). I am able to SSH into the Pi remotely and run basic commands, top, ps, ping. After about 15 minutes, the Ethernet LEDs just went off and my SSH session is gone too.

 

Checking the voltage at TP1 with my DMM it reads between 4.75 to 4.8V when the Ethernet is up and 4.9V when the Ethernet is down, i.e. the 3 LEDs marked FDX, LNK and 10M are off.

 

The same symptom is happening with both adapters. I have nothing else plugged into the Pi except the power and Ethernet cable.

 

Could this be another power problem? Anyone else seeing similar issue?

    Mine should be the second batch then since it's using HanRun HR901110A and the manufacturing date on the board says 1213.  I will have to find the HTC charger to try it out and will report back if that helps.

    If you want to experiment, another thing to try would be a different SD card. One thread on the Pi board here

    http://www.raspberrypi.org/phpBB3/viewtopic.php?f=6&t=5900&p=78495#p78495

    reports a temperature sensitivity (will not reboot when hot, but reboots OK if kept cool with a fan). This may occur with specific SD cards (not yet confirmed).  If you have a fan, could try running the fan over the Pi also. If that fixes the problem it would be very interesting to say the least.
