Looking for any information on why they blow fuses #1
 
In the event this isn't a troll post, please state:

What fuses? The line fuse/circuit breaker at the panel? The fuses in the cabinet? What model are you talking about?

You could have a dead short across a station or tunk pair on the cross-connect block, you could have gotten a bit of cross-connect wire into the system by accident, some component failed - like a hard drive, tape drive, or even the power supply itself.

Usually fuses blow when there is too much load across them. A fast-acting fuse will respond quickly to an overload, and a slow-acting fuse fails over time.

Back in my CBX 8000 days I could blow a fuse just by simply accidentally shorting across a pair while cross connecting. The newer stuff seems more resistant to quick bursts like that, but I'm sure a sustained short would trip something out or blow the port on the board.


 
The only Siemens i know of is the old Hicom 125 and 130 when the pin 3 and 4 are short cutted. They had al lot of fusses on the last board.
