| Ascend MAX 4000 power supply help 2

|
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. | |
Picture 1

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. | |
Picture 2

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. | |
Picture 3

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. | |
Picture 4

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. | |
| And these modem boards are the problems. They consume too much power, esspecially the new 16 digital V.90 modems.
The more you have, the faster the MAX dies. |
