PoE has its day
Notably this is very useful for VoIP phones, like the SNOM 300, and for access points for WiFi. Both of these can end up being put in places where power is a pain to arrange. Phones because of yet another power socket and lead on a desk, and APs because they end up high up and above false ceilings and so on. You want to be able to put an AP where it works best, not where it is in range of a power lead. PoE works over 100m cat5 cable.
Up until now we have used very little PoE stuff, largely because PoE switches are expensive. At home I want fanless switches to keep noise down.
I was quite pleased to see that you can now get an 8 port gigabit unmanaged fanless switch with 4 ports PoE for under £100! It seems netgear, dlink and tplink do them. These are not necessarily the best names in switches, but for home use and for such a low price, they are well worth considering.
The fact you can power 4 devices of one of these switches also saves having power adapters and extension leads. Reduced mess and leads always goes down well with the wife :-)
It has allowed me to place the home AP in a sensible place, high up on ground floor, where I happened to have network already, but no power.
