How to choose a power supply
Match voltage, current and plug
Read the label on the original power supply and match its output voltage, current and plug. Values differ between series, such as the 42 V Alcatel power supply for the 4018 or the 24 V power supply for the Polycom SoundStation2 and Avaya 2490.
Mains adaptor or PoE injector
If your network switch supplies Power over Ethernet (PoE), most IP phones need no adaptor. Without PoE, use the phone's own mains adaptor or a PoE injector that sits between the switch and the phone.
Check the PoE type
Most current IP phones use standard 802.3af PoE. Some older phones and injectors use a maker's own pre-standard power, so check that the phone and the injector use the same type before you connect them.
Replace cabinet supplies by part number
Cabinet power supplies fit one system family. Use the part number on the failed unit, for example the Avaya 655A for a G650 cabinet, the PS4504 for a G450 gateway or the Panasonic KX-TDA0103 for a KX-TDA600.
Conference phones and wireless handsets
Polycom conference phones, such as the SoundStation IP 5000, 6000 and 7000, use their own power supplies. For the Cisco 8821 Wi-Fi handset, a battery and charger set is listed here.

Questions
Do you sell used and refurbished power supplies?
Yes. Most power supplies in this range are refurbished, and some are new. The range covers power supplies for business phones and phone systems only, so check the model on your phone or cabinet label before you choose.
Which Polycom power supply do I need?
It depends on the phone model. Polycom VVX desk phones, CX500 and CX600 phones, and SoundStation conference phones each use their own power supply. Check the model on the label under the phone, then choose the power supply listed for it.
Can I use a power supply from another brand?
Only if the voltage, current, polarity and plug all match the original, as a wrong power supply can damage the phone. Third-party units made for a specific model, such as the third-party Cisco CP-PWR-CUBE-5, name the phones they suit. If you are unsure, send the part number through a quote request.
Does an IP phone need a power supply if I have PoE?
No, in most cases. An IP phone on a PoE switch port takes its power through the network cable. You need a power supply or PoE injector only when the port does not supply PoE, or when the phone needs more power than the port gives, for example with several button modules.
