A question for anyone who has a 7800/7900 phone and an SX20

[Nadav]

Does the power connector for the power supply of the 7800/7900 also connect to the SX20?

I'm aware that different power supplies are necessary, but I'm interested in the actual connector compatibility.

As a side note, does anyone know the name of the connector type for the 7800/7900 phones?

Thanks :)

Hi Nadav,

For 78XX

Cisco power injector

●  The IP Phone 7811, 7821 and 7861 are compatible with Cisco Unified IP Phone Power Injector (CP-PWR-INJ), and 7841 is compatible with Cisco Aironet Power Injector (AIR-PWRINJ5=).

So 78XX would use CP-PWR-CUBE-3 which is backwards compatible with 79XX series, see below

BUt not SX20 see below

Hi Jitender,

I'm not asking about the power cube compatability but rather just the connector (the part that connects the powercube to the SX20). I'm interested if it's the same connector :)
