Spinnaker Board Problem?

[Iffat Iqbal]

Hey, I was working on my SpiNN-5 board in my lab after not really using it in a bit, and I have it on ssh and used to be able to run scripts on it fine before, but for some reason, upon running a script now I continuously get thrown the error below (SpiNNman cannot connect to machine error). I checked the physical board, and everything seems to be running alright (in terms of the status LEDs). I was wondering if any of you ran into this before and how to solve it?

Hi,

That does suggest that either the IP address is wrong, or something has gone wrong with the machine. Can you ping the IP address you are using for the machine when it is on? Are there flashing lights on each chip and on the Ethernet port? Are you definitely connecting to the outermost Ethernet port?

Andrew :)
