APC External Battery Pack for Smart-UPS Extended Run SMX-Series, SMX120BP, 48V, 4U Rackmount/Tower Convertible Black

I ordered this to go with a Smart-UPS X 3000VA unit. This and the new Smart-UPS replaced a pair of underwhelming 1000VA units for our servers. This unit added on to the Smart-UPS X 3000VA provides us with 77 minutes of back up power with about 45% load from for our Domain Controller, SQL Server, Terminal Server and VOIP Phone server. As with any battery backup unit, it is HEAVY - this is about 140lbs (50lbs for each battery and 40lbs for the case). This made it especially difficult to move into our network rack located in the attic (Yes, attic - I know it isn't an optimal location, but it wasn't my decision). To make moving this unit as easy as possible, I decided to remove the batteries and move each component separately. A highly recommended solution for moving this unit.

Sadly it did not add as much time as I wanted it to due to the fact our rack has so much equipment.

Good form factor, lots of plugs and software works well. Network Management card is pricey but totally worth it. I've had good luck with APC units in the past and will continue to buy them.

Repackaged product, came with battery connected (big no-no), bezels installed (so naturally broken), and no documentation that normally comes with a apc battery to speak to its mfg date / testing verification. I cannot validate that this is a OEM battery installed, i have broken bezels meaning tons of plastic pieces inside the case that could potentially destroy the fans. Extra annoyed since i needed this asap and need to wait for another shipper to get a new one.

Power!!!! Seriously, works great for a rack of 3 servers, with extra battery modules, gives us over 3 hours of run time.

Despite being a little heavy, it was a matter of unboxing, putting in place, and connecting the cable. This version no longer requires running the app to make the master aware of the number of battery packs. It was easy to install; it was affordably priced, and shipping was free, they arrived quicker than expected in a pinch!

I bought one of these elsewhere, I believe it was from Jet. The unit has been great for the past 5-6 months with one small flaw. Both PSU's on our Juniper Router were plugged into this; every 3 weeks or so our router would reboot. Considering it takes about 10 minutes for the router to reboot, this was a HUGE issue. This occurred 3-4 times before I finally had an epiphany and thought that maybe the UPS was briefly cutting power to the router, causing it to reboot, so I removed one of the PSU's from the UPS and plugged it into the raw outlet. That was 3 months ago and our router hasn't rebooted since. We also have servers plugged into this that haven't rebooted, my guess is they're less sensitive to brief power disruptions. So beware of very sensitive networking equipment; this guy might be the cause of the exact thing you're trying to avoid.

Great product. Shallow mount. Decent price for what you get.

Needed a large UPS, choose that one since I read it had a NW card, but only found it was optional when I received the unit. There is no way to control more than one server in outage unless you get that NW card, the software does not have other way to access the addtional machines.
