The part on the front is called an LNB. LNB stands for ?Low Noise (amplifier and) Block (downconverter). It takes the signal coming from the satellites and amplifies it. It also translates the signals from the high frequencies used for satellite into ones that can travel over a cable. This takes power, of course. In the case of older systems, your satellite receiver provided that power The advantages of doing it this way Using a separate power inserter has its advantages. First of all it provides enough power that the dish can not only amplify but do other tricks. Using a single-wire system is tricky and it requires that all the signals sent out don?t interfere with each other. This requires more power. Also, using a single power inserter means that all the receivers don?t need to have power supplies big enough to power the dish. This makes it possible to have smaller boxes like the DIRECTV H25 which can only be used in a SWM system. So, by having a single power inserter you almost always save energy compared to having two or three (or more) full-power receivers in your home. Genie 2 systems used at home can also power the dish without the need for a separate power inserter. The goal of this sort of system is to give the customer as few little boxes as possible. No one wants a cluttered installation. But, if you choose to have some redundancy, you can use a separate power inserter with Genie 2 systems too. If it gets unplugged? If you accidentally unplug the power inserter, the world will not come to an end. Most likely you will start getting 775 errors on your receivers, and at some point the picture will probably freeze and go black. While plugging the power inserter back in will solve this, it?s best to reboot the receivers as well, after waiting 30 seconds or more for the power inserter to get everything balanced again. Some people have reported running without a power inserter for an extended length of time but it?s not recommended; even if it does work (and it almost never works) it will burn out the LNB as it tries to use the little power it can get.
