1. PoE Switches to power and connect IP Phones
2. Remote IP Phone in Gatehouse etc, connected over fiber
3. Add an occasional PoE powered device to a standard Ethernet Switch

2Power over Ethernet (PoE) Phones IP Phones require Power and IP connectivity, i.e. need PoE Switches
Different IP Phones need different amounts of power
Linksys SPA922, SPA942, SPA962 - 5.0 Watt (Class 2) (5.0 Watt x 24 = 120 Watt)
Polycom IP330, IP335, IP335 - 4.0 - 6.3 Watt (Class 2) (6.3 Watt x 24 = 151 Watt)
ShoreTel (not inc BB24 with IP560) - 2.8 - 7.1 Watt (7.1 Watt x 24 = 170 Watt)
Polycom VVX1500 - 11 Watt (Class 3) (11 Watt x 24 = 264 Watt)
(24 off would consumes too much power for low cost PoE switch)
Different PoE switches provide different facilities and different total Power
Total PoE power of Switch must exceed total PoE consumption of phones!
