IBM OP500 Uninterruptable Power Supply

Help! My UPS has been sitting there hidden away for years. I recently found that it no longer worked - didn't seem to hold a charge. I thought the best bet was a worn-out battery so I replaced it. It still dosen't seem to be working. When I unplug it trying to test the battery back-up, everything dies. Currently, there is a yellow light blinking which has a picture of a battery with a slash through it. The first thing I would like to do is find the operating instructions and make sure I'm operating it correctly. They should be no more than a page or two. Thanks

Re: IBM OP500 Uninterruptable Power Supply

Http:// that is the link to the manual you need. It sounds like your UPS is not turned on correctly. You must press and hold the on switch. Make sure the AC sign wave is lit solid not blinking, the battery should not be lit as well. If the battery is yellow, that means you are running on battery, if it is red that means the battery is low.

UPS - Battery Fault

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault. A faulty charging circuit will not charge the batteries and will also cause a fault condition.

Lower powered and cheaper type UPS are switch over types, when the mains supply fails, the UPS switches over to the battery and inverter in milli-seconds which then supplies mains power to the computer and peripherals. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.

NOTE the power waveform from these UPS is a pseudo sine wave (i.e. not a true sine wave).

The true UPS types are usually the higher KVA units (over 1500 VA) that supply continuous mains power. The mains power is connected to a charger which charges the batteries and the inverter draws power from these batteries and converts it to true sine wave mains power to the computer equipment, therefore there is no switch over time lag when the mains supply fails.

My APC350 backup ups has a overload when power is interupted with no load connected. The unit will start beeping but does not supply battery back up. The power supply to the battery shows 14.4 volts and...

It may still be supplying power but the surge arrestors were probably damaged by the surge. Go to choose support from the menu bar, they should be able to help or maybe even replace your unit.

Overload Red button is on even after pressing reset button @ back

Try unplugging some equipment from the UPS. The total load should be less than 865 W. Printers and scanners often are culprits.Some gaming desktop computers can have a power supply that will be too much for this UPS. (I've found that even having the printer on the surge only part of the UPS can be a problem. I have the printer on a separate surge protector.)

Since the overload is new, did you add any equipment to the UPS recently or upgrade components?

If you reduce the load, and the problem continues, the UPS may have a fault in the circuitry. If it is under warranty, contact APC.

I hope this helps.

(I have replaced APC units after 3+ years when they can't properly recharge the battery - with a new battery. The symptoms are 1) getting a overload when a small load is on the UPS. Small load - desk lamp, 13" TV or 2) not keeping the item on when the power goes off.)

My UPS Turns itself off

This advice relates generally to small UPS units.

More than likely it was the UPS that was beeping because it was supplying the power from its inbuilt battery, rather than the CPU. From the model number, I would predict that this particular UPS is an 800VA unit. Presumably it has worked reliably since its original purchase.

You may be experiencing power network disturbances that are resulting in low voltage (otherwise known as 'brownout'). This could be a 'new' or 'temporary' power issue or something that may now be more permanent. Some examples of 'new' issues that can lead to low voltage include: a neighbour operating a large welder, an X-Ray clinic opens next door or the power supply authority incorrectly adjusts transformer output or overloads the grid (new subdivision?). Look for likely external issues and if found address these with the relevant party.

Be aware that an 800VA UPS may only run a PC for 10 -- 15 minutes (not 45 minutes or more) before the battery is flat and the unit shuts down and has to be restarted. It can also take many hours for a battery to fully recharge and if there are repeated demands on the UPS to supply power over this time then the recharge period will be extended.

Also check that you have not overloaded the UPS by connecting any printers or non-computer loads to the battery-backed supply, especially laser printers which can easily overload a small UPS when the fuser operates.

If chronic unresolved low supply voltage is a problem, check the user manual / software. Some UPS manufacturers provide adjustments for the lower voltage threshhold -- i.e. the supply voltage at which the UPS will come online to supply the load. This can be reduced to avoid unnecessary operation of the UPS.

Finally, a typical life for a small UPS battery is around 2 - 3 years. Problems described could be attributed to a failing battery.

My ups battery backup time is too short even i replace the battery

sounds like you have too many devices plugged in, it's not the ups that's failing it's the amount of power it takes to keep all you devices running. you may want to buy a larger ups or you can unplug some of the devices you don't need in the event of power outage. if it's just your pc your power supply might be sucking up alot of juice, i'd check and see what the power consumption rate is on that particular power supply.

I plug it in and there is no power output. I opened it up and put a voltage meter on the internal batteries and they were nearly dead. Do they need to be replaced? Plugged in to recharge. Unit sat unused...

After batteries sit for an extended period of time they slowly discharge. Sometimes charging them for a day or two may help. Sometimes not. The chemical action inside the battery has been used up, and will no longer recharge.

My advice would be to replace the batteries.

UPS power goes off instantly as soon the external supply stops.

In our office, I have had to replace UPS batteries AGAIN two years after I replaced the original batteries in the units. I had purchased the replacement batteries locally, so I don't know if the brand of replacement batteries was not as good as the original batteries or what. But your weak battery light is not flashing ... I would try a replacement battery (if it isn't too expensive) but I know that some of the older batteries are no longer used in the newer UPS units so if the problem wasn't the battery you are stuck with a new battery and nothing to use it for.
