20 Most Recent NEC APC Smart-UPS 1400 (050-01803-000) UPS System Questions & Answers

Any UPS monitors the incoming AC level to determine if it is needed or not.  I think the APC unit doesn't know any more when it is needed; it's sick.

may be power to the UPS went off or was not within permissible limits, hence the ups run on batteries until they were completely discharged, the servers went off because they are supplied by this ups. check the power supply to this ups, somebody could be switching it off accidentally. try to sitch the inpu power to the ups to see whether the batteries are okey

greg milton, Hi, Did you get the top cover off of the "1400" battery back-up? How old were the batteries in the unit? My APC 1250 has two 12v 18ah units inside. It's best to replace batteries every 3 to 5 years! 12fixlouie

The UPS has a fauly/problem.
If your UPS is approx. 600VA, then it is not a true UPS unit but a switch over type. When the mains power fails the UPS switches over to the battery and inverter in milli-secs to provide mains power.
If you turn off the mains supply and shut down your UPS, but you are still getting mains power, then there is a fault with the switch over circuit.
You need to get this unit serviced.

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. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.
The other possibility is the charging circuit may be faulty.

The sealed lead acid batteries in them have come down a lot in price now, see here for one on batterytrader, 12v 7ah sealed lead acid battery

The basic design hasn't changed since day one...there maybe a few more bells and whistles now, If the unit is working fine...change the battery...and use the unit...BTW..just for your info large UPS'S are kept in service for 10-15 years or longer...hope this helps

Better late than never...

The older Smart UPS models are peculiar in the way that they appear dead (will not power on) if the battery is completely bad.

Replace the battery, and the UPS should come back to life.

The APC 1400 is a single phase device...I'm not sure what it is that transpired can you explain a little more in detail please

That meens that UPS dont have battery power for minimum time (2min). Unplug some devices so UPS load need to drop below 25% and lets UPS recharge battery

just remove the battery again & dont put it back till 30 minutes then connect ur batter again.

This is the battery you need to replace http://www.batterywholesale.com/battery-store/proddetail.html?prodID=619

The NEC Mobilepro 770 is a legacy device that was released in the early 2000s and uses Windows CE as its operating system. Since the device is no longer supported, it may be challenging to find software and drivers that are compatible with modern operating systems like Windows 10. Here are some steps you can take to transfer files and connect to the internet:

1. Get the necessary cables: You'll need a USB cable to connect the Mobilepro 770 to your Windows 10 PC. The cable should have a USB Type-A connector on one end and a mini-USB connector on the other.
2. Install ActiveSync: ActiveSync is software that allows you to synchronize files between your Mobilepro 770 and your PC. Unfortunately, ActiveSync is no longer available for download from Microsoft, but you may be able to find an archived version of the software on the internet. Install ActiveSync on your Windows 10 PC and connect your Mobilepro 770 to your PC using the USB cable. If the device is recognized, you should be able to transfer files between the two devices.
3. Connect to the internet: The Mobilepro 770 has a built-in Ethernet port that you can use to connect to a wired network. To connect to the internet, you'll need an Ethernet cable and a wired network connection. Plug one end of the Ethernet cable into the Mobilepro 770's Ethernet port and the other end into your router or modem. You should be able to browse the internet using the Mobilepro 770's built-in web browser.
4. Install additional software: The Mobilepro 770 comes with a basic set of software, but you may want to install additional software to make the device more useful. You can download and install software from the internet, but make sure it's compatible with Windows CE and the Mobilepro 770.

Keep in mind that the Mobilepro 770 is a legacy device, and its performance and capabilities may be limited compared to modern devices. It's also possible that some of the software and drivers you need may no longer be available or supported.

They don't make them like that any more! The Service Manual lists it as a standard IDE drive. Your best bet is to take it to a local computer shop. They can remove the drive and add it to a test bench set up, then transfer all the data to a pen drive as the hard drive is only 2.1 Gb. https://www.manualslib.com/manual/366990/Nec-Versa-4000.html?page=42&term=hard+drive&selected=3#manual Or use the power supply from another old computer, as the connector plugs should be the same, 12 volt and 5 volt. Or get another on eBay NEC Versa 4050c 90mhz Pentium laptop off eBay for $25 shipped. It has a 2.1gb drive, 40mb of ram. It came with a docking station. https://www.google.com/search?q=NEC+versa+4050c https://www.google.com/search?q=nec+versa+4050c+transfer+data+to+pc ..

DVI video cables don't carry audio. Thus you need to use an audio extractor or converter instead of just an HDMI to DVI adapter cable. Try something like this: https://www.amazon.com/J-Tech-Digital-Extractor-Converter-JTDAT5CH/dp/B00BIQER0E/ref=psdc_280341_t1_B01MQYTUAK . Then connect the HDMI to DVI cable to the HDMI out of the converter. Then the audio out to one of the audio connections on the LCD4610-BK. Note: this converter requires you to get the extra HDMI and audio cables separately. Depending on your ROKU device, you might need an HDMI (F to M) adapter to ensure that you aren't blocking other things on the front of the converter. Then set the monitor to the appropriate video and audio inputs separately. I hope this helps. Cindy Wells
