To give you an impression about our skills :

Here on the right picture you see, that the fan blows beside the power supplies !!!

No air is pressed through the almost totally

covered and heated electronic circutry.

You see three copper wire coils looking like new coils, - but the coil in the lower middle is slightly burned, the result of one modem card. Anyhow, this one was working all the time.

This power suply is broken, the coil is heavyly burned. The result of 2 Modem cards. We would change the capacitors too, nobody knows how long they will work.

This one had 4 modem cards in it and is totally burned, working about half a year in a cold basement.

But is was working a suprising long time,as the customer told us.

The last picture is the end of life after 4 weeks with 6 modem cards. The coil is completely burned off, two capacitors are blown up and the copper wire from the cloil is broken. This system must have been very hot over a long period.
