If you look at the above picture you can see the front fascia at the top, where the status Leds are. These leds are very important and the more information they can convey the more useful it is, especially in a corporate environment.
Unfortunately the APC Back-UPS range as you can see has minimal information shown by the Leds. It is unlike the APC Smart-UPS range as there are no indicators showing that the voltage is under/over and is being boosted/lowered by the UPS. So with the RS you only get leds showing the UPS is operating from utility power / is on battery / the circuit is overloaded / the battery has failed. These are the minimum which you would require really. One of the reasons that you do not have the additional Leds which the Smart-UPS range has is that the APC Back-UPS range actually does not include that functionality therefore cannot include those Leds.
So let us look at the business end of the UPS, namely the rear. You can see that APC has everything catered for, there are 6 Battery Backup power sockets which is quite satisfactory. Enough to connect 2 PCs and monitors and two other pieces of equipment. Then there is another 2 Surge only sockets for protecting your other pieces of equipment from damage.
There is additionally 1 set of LAN sockets (in and out) and 1 set of Modem protection sockets (in and out).
There is no fuse however, it has another system which cuts out if there is any overload. Then you reset the device with the reset switch on the back instead of having to go find another fuse. A much better more user friendly system. After all, anybody can push a button.
There is a fan also at the back which cuts in when it goes onto battery power. It is much larger than those I have seen before. Then at the top there is an RJ45 socket which you plug in a supplied cable that has a USB connector at the other end.
This is how the supplied APC Powerchute Personal Edition software communicates with the UPS. Personally I just hate proprietary cables and that is what APC have specified here. A downside indeed, lose it and you will have to source another from APC instead of just buying another inexpensive USB cable from any shop.
While we complain about the cabling APC has started to include no cable to power the units as standard although they include two cables to power the equipment. I have loads of cables lying around so that is not a problem for me but someone else might have to go shopping again to buy a power cable.
