Power Over Ethernet (PoE) is a technology that lets network cables carry electrical power to many different devices on a network. With VoIP, utilizing PoE means phones have a single connection to a wall socket, and can be remotely powered down, just like with analog (PSTN) phones.
Many phones are PoE ready right out of the box, but utilizing this feature will require a PoE Switch or Router that is capable of sending the power the devices need.
The following models support optional PoE:
- IP331 - Polycom 2 - Line
- IP335 - Polycom 2 - Line
- IP550 - Polycom 4 - Line
- IP650 - Polycom 6 - Line
- VVX201 - Polycom 2 - Line
- VVX310 - Polycom 6 - Line
- VVX410 - Polycom 12 - Line
- VVX500 - Polycom 16 - Line Touchscreen
- VVX600 - Polycom 20 - Line Touchscreen
- SPA504G - Cisco 4 - Line
- SPA525G2 - Cisco 5 - Line
- IP20xx - Vertical 2 - Line
Using PoE with IP20xx - Vertical Phones:
• To use a Vertical desk phone with PoE, move the power switch to the "POE" (down) position.
• To use a Vertical desk phone with the power adapter, move the power switch to the "Adapter" (up) position.
Using PoE with Polycom Phones:
• When a Polycom desk phone has a power adapter plugged in, it will not attempt to get power from the Ethernet cable.
• When a Polycom desk phone has only an Ethernet cable plugged in, it will attempt to get power from the Ethernet cable.
• The Polycom phones auto-config to use the correct power level using 802.3af, which all unmanaged & managed switches support by default.
If your IT needs to manually configure the phones' power level with a managed switch, they may be able to configure this themselves. Intermedia Voice Support cannot assist with manually setting the PoE power levels; however Polycom does offer an official PoE document that details Power Classification: Polycom's PoE PDF.
