"Also useful for 48V DC POE devices"
Appears to implement 802.3af Power Over Ethernet (POE) standard in full. Marked down because the documentation supplied and available on Linksys web site is so dismal.

I'm using it with a Cisco 7960 phone, though that requires a custom cable with pins 4&5 swapped with 7&8, since the phone uses Cisco's pre-standard POE pin-out.

"Only complaint is that they didn't offer it two years ago..."
Perfect, simple product for the nagging problem of getting line voltage near your electronics. Other versions have been available from other sources for a while now, and you could always roll your own, but this is a nice, elegant, reasonably priced package that does precisely what it should do.

By the way, the other reviewer's comments about mixing 5 volt and 12 volt components is incorrect. You should NOT use a 5 volt power source with a 12 volt device. Granted you *probably* won't damage it, but IF it works - which is unlikely - it will probably be unreliable. I'm an Electronics Engineer with over 25 years of career experience; it's up to you whom you should trust!

"Last review about 5volts versus 12volts is incorrect"
The last review saying this product will not work with Linksys's 12volts products is incorrect. The general rule of thumb is NOT to supply a HIGHER voltage than the device specification recommends because you will definitely damage your device, including make it smoke. For example, never input 12volts into a device which requires 5volts. However, if you input 5 volts into a device which requires 12 volts, the device will usually be OK. The Linksys POE works perfectly with all my 5 volts access points, some which are not even Linksys.

"5 Volt Only - won't work with WRT54G v.2 or WRT54G"S""
The newer Linksys products including the WRT54G v.2 use a 12 volt power supply and will not work with the WAPPOE. Linksys lists on the product page for the WAPPOE that it will work with the WRT54G but in reality it will only work with the v.1 and v.1.1 that use a 5 volt power supply.
