Remote reset for Pogoplug E02 or GoFlex Net? (no replies)

(First time poster so don't hesitate to point me to existing ressources/posts that I may have missed when searching)

Hi all,

I'm planning to leave powered-on a PogoPlug E02 or a GoFlex Net (most likely the GoFlex net) in a second home.

In case something happens, I'll have a second machine (currently HP microserver, running VmWare ESX, with remote management card), that I could wake/power-on remotely, and then connect to the E02 or GoFlex, using the serial console.

My problem is how to 'reset' the board: I installed uBoot + Debian (on E02 but will look into GoFlex Net soon) and everything works well, however if the Linux kernel hangs for any reason, I don't know if I can remotely reset the board.

Currently, I'm power-cycling it by commanding a relay from the HP microserver, but wondering if something simpler could be achieved.

Therefore:
1. is it possible to reset through the serial connection?
2. is there some kind of hardware watch dog mechanism on the board (so that if kernel hangs, the watch dog will detect this and reset automatically the board) ?
3. would the JTAG/OpenOCD approach allow reset (I think so but never used JTAG yet) ?

All advices are welcome, thanks for your help!
