Although Hepatitis E often causes an acute and self-limiting infection (the virus usually resolves itself and the individual recovers) with low mortality rates in the western world, it bears a high risk of developing chronic hepatitis in immunocompromised patients with substantial mortality rates.
IEEE 802.3 PoE Plus - March 2005 Telephony Products PoE Power Requirements A fully loaded 24 port 802.3af installation requires approximately 370 watts. If PoE Plus max power is 30 watts per port, then a fully loaded 24 port installation would require approximately 720 watts. This requires a substantial UPS.
At a distance of 1 meter from the bulb/candle, the 1 watt of light power is spread over an area of about 12 meters square. The power density is then about 8 * 10 ^ -2 watts per meter squared at a meter's distance. In the referenced article, it is calculated that a minimum power density of 6.28 times 10 ^ -15 watts per square centimeter is needed to see a red light source. This is 6.28 * 10 ^ -11 watts per square meter.
