The PI100 802.3af Compatible 10/100 Mbps Power Over Ethernet (PoE) Injector works with any and all access points that are also 802.3af PoE-compatible. The PI100 is self-contained with both a Power Over Ethernet PoE injector adapter and a power supply all in one. This makes it much easier to deal with when keeping a clean cable room. The PI100 also has 100/240 Vac support and supplies 48 Vdc to all units. The PI100 PoE injector adapter puts power over pairs 4, 5, 7 and 8. This unit can also be used with Cisco PoE equipment using an altered pin out on the RJ-45 cable. The PI100 also provides auto-recover, over-voltage and short circuit protection.
