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:

Workpoint power supply method optiPoint 150 optiPoint 400 optiPoint 410 optiPoint 420 optiPoint 600 AP1120
AC/DC Power Supply unit Yes Yes Yes Yes Yes Yes
Pre-standard IEEE 802.3af mid span PoE injectors Yes Yes Yes Yes Yes No
IEEE 802.3af mid span (via unused pairs) Yes No Yes Yes Yes No
IEEE 802.3af end span (via used pairs) Yes No Yes Yes No No
Cisco Power over LAN (via used pairs) Yes No Yes Yes Yes No

AC/DC Power Supply unit

Each IP workpoint has its specific compatible 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. Unplugging or switching off the power to the IP workpoint will cause its de-registration. Power over LAN As shown in the table there are four types of power over LAN. Not all of these are supported on every phone. • Pre-standard IEEE 802.3af PowerDsine power hubs with spare pairs • IEEE 802.3af mid span (spare pairs) as provided by the current PowerDsine hubs (as well as PowerDsine pre-standard) • IEEE 802.3af end span (used pairs) as provided by all data vendors from their Ethernet switches (including Cisco) • The Cisco pre-standard (used pair) inline power as installed in many older Ethernet switches.

Power over Ethernet Midspan (PoE injector), with 1,6,12 or 24 output ports, is connected in cascade to exisintg Ethernet Switch/Hub. As such, it is a scalable solution for upgrading a network to support Power over Ethernet
