SCXI-1001 Fuse Issues

[MTLLockheed]

I returned from the weekend to find that one of the SCXI-1001 chassis that I have had blown a main power fuse. I replaced the fuse and turned it back on, upon which the fuse blew again. I then took out all the modules, replaced the fuse and turned it on again; normal power up occurred. I then turned off the chassis, inserted a module, turned it back on, and repeated this process until the fuse blew again (4 modules later). This would lead me to believe that the specific module was bad. SO, I repeated the steps with modules known to me ok. After 3 modules again, another fuse gone.

Is there any more trouble shooting I should do? What actions should I take to get this problem resolved and insure all modules involved are ok??

Hello MTL,

Have you seen this forum post:

Something I would also try is to define if it is the combination of modules. If is not the modules, the last thing it could be is if the fuse is not slow blow. This means that at the very beginning there is little more current than later. The forum post also have the link for the recommended fuse (if you are not using NI's).
Hope this helps but if not, I would call us for sending the unit back for repair.
