I have a BX900R that suddenly the red light came on and the alarm sound was constant - not beeping and the unit did not supply any backup power. The most recent status on the monitor program showed about...

If the device was still under warranty, you should call APC support and ask to send it in for repairs or replacement. Just keep politely asking, and ask to talk to their superior whenever they say it isn't possible and eventually you will get an RMA ticket/number.
If the device is not under warranty, you might be able to convince APC to service the device for a fee.

Yes there are replaceable batteries but if yours is only 6 months old and was new this should not be the problem. That said, batteries only have a certain lifespan from the date of manufacture. If it sat on a shelf for a long time before it was sold the battery could be junk.

Is the tone continuous? If so this is the overload alarm.

Has started to beep whenever items plugged into

If it's more than 3 years old, you probably need new batteries.

If the beep started after plugging anything additional into the UPS, you may be in an overload state, and the beep is telling you that it's choosing to beep and not function as intended rather than smoking itself. Try unplugging a piece or two from it and see if the beep goes away. If not, probably just you're batteries giving out due to old age, they'll only give you 3-5 years.

On line and on battery LED is blinking simultaniously

Sound like you may have a problem with the new battery.
Check the water level on the new battery.
Check all your connection and if you are still having the same problem, Try removing the existing battery and jump of your car battery.
You can do this without the computer on line and will tell you if your existing battery is at fault.
P.S. You must disconnect the existing battery to do this test.
Good luck.
I have used Tractor battery's from H/D, cost about $24.00 and will do as good a job. Only problem is the size.

Pen drive unable to Read

Have you tried to use the pen drive in another computer. If the pen drive does not work in another pc then this pen drive could be fried. There is whats called "Safety Removal Hardware" This should be used before removing any hardware from the pc. Also have you ensured that all the updates have been carried out on that computer?

Tony166, according to the web, the Panasonic DBS 576 single cabinet phone system will run at a peak wattage of 360 or 3.3 amps. 3.3 amps x 120V = 396 VA.

Also, this is a very sensitive device and needs good clean power to eliminate frequency variations and line noise. You should put this system on an On Line or Double Conversion UPS. Not a Line Interactive or an Off Line unit! Those are the 3 UPS industry standard technologies. The Off Line technology is simply a battery in a box. It can break down a clean sinewave input and feed your connected load a stepwave signal. The Line Interactive unit will provide a sinewave while on battery power, but not during normal operation. Only a true On Line UPS will provide pure sinewave power 100% of the time!

I would suggest at least a 1kVA or 1.5kVA Liebert GXT2 product!
