This one is interesting. We have a 2 cabinet Fiber Remote (Option 11 cabinets) that have the NTAK04 Power Supplies, each connected to a dedicated NTAK75 Battery Box. We replaced the batteries, let them charge for 24 hours and then tried a load test. The breaker tripped and the test failed on both cabinets. Through the process of elimination, we ended up replacing both NTAK75's, both NTAK04 Power Supplies, both battery cables (between the PS and batteries) After everything had been replaced, when we turned on the breaker in the NTAK75, it sparked and the breaker tripped and stopped half way between on /off. I was able to toggle the breaker all the way off and now it will stay in the on position. However, when AC powor is pulled from the cabinet, the battery light on the NTAK04 goes out and the cabinet gets no power. The battery light on the NTAK75 stays lit and there is constant -52 volts in the box. One other thing, the battery light on the NTAK04 goes on and off with the breaker switch in the NTAK75.
Since everything above has been replaced, my question is: could the Option 11 cabinet itself have an issue and need to be replaced? I don't think the backplane has anything to do with it, but I've been mistaken before. LOL
Any other suggestions are welcomed.
Thanks!!

I don't mind coming to work, but that eight hour wait to go home is a bitch.
