Would be nice to add an overview table like this one:
 
  
The optiPoint IP workpoints can be powered using different methods as listed in the following table:

AC/DC Power Supply unit
 
 
Each IP workpoint has its specific indoor AC/DC power adapter, that adapter is used to power the IP workpoint and is generally supplied with each IP workpoint as an accessory.
 
 
Power over Ethernet (PoE)
 
 
As shown in the table above there are four different methods to feed power to IP workpoint.
 
Not all of these methods are supported on every workpoints (See, as examples, differences between optiPoint 150, optiPoint 400, optiPoint 600 and HiPath AP1120).
 
 
* Pre-Standard IEEE 802.3af mid span PoE injectors (known also as power hubs) using spare pairs wires of Ethernet cabling infrastructure.
 
* IEEE 802.3af Standard mid span (using spare pair wires) as provided by the current and pre-Standard power hubs
 
* IEEE 802.3af Standard end span (using used pair wires) as provided by all data vendors from their Ethernet switches (including Cisco)
 
* CISCO pre-standard (using used pair wires) inline power as installed in many older Ethernet switches.
 
 
Power over Ethernet mid span (PoE injector) is connected in cascade to exisintg Ethernet Switch or Hub.
 
As such, it is a scalable solution for ''upgrading'' a network to support Power over Ethernet (PoE).
