PoE looks an impressive thing to me. I am still not sure how this technology replaces the traditional power backup plans such as battery and generators etc.
Interesting article. One can not depend on singe source of power. PoE devices look promising to solve this kind of a situation. I have a question though - Can PoE devices handle heavy electricity requirements ?
Emergency Communications and SOP’s can function although less effectively without electricity. The norm is to have backup power for all essential emergency services and communication equipment. In some companies we had two back up energy sources. However, we conducted routine drills designed to assume worse case scenarios and we did drill assuming 100% failure of our emergency power sources. The drills allowed us to practice theoretical solutions and fine tune these solutions for the real world. Fortunately, in my career we never experienced a compete failure of emergency power systems. I believe today with almost every individual owning a cell phone, universities and others can effectively communicate in emergencies with zero power.
Like mentioned in above answers, we can't rely on single power source as well for emergency purpose, backup power supply is needed and has to be included in your Emergency response plan. Hope this helps.
Typically Emergency Communications have at least one backup power source. This can come in the form of a battery Uninterruptible Power Supply (UPS) and/or an emergency generator.
