The proposed Test Box will be similar to the one used for testing the Patch-Panels :
TestBox1(JPG-File, 79KB)
The test program runs under PC control via the parallel port
 TestBox2(JPG-File, 57KB)
On top: High-Voltage card
            
For 256ms I was considering of adding a movie, with an ecclipse in the background, slowly zooming
on the box, with some monumental music (something like the Richard Strauss' "Also sprach Zarathustra",
you know : Burrrrrrrrrr, Traaa, traaa, traaaaaa, Ta-daaaaaaam, tam-tom tam-tom tam-tom tam-tom ....),
but then I thought 'oh, what the heck!' and I leave it to your imagination. I just hope that it will not start
to multiply itself, doubling every 74 hours, eventually eat up the whole Earth and turn it into a supernova...
