9951 with two KEM

Hi Philippe,

Here's the clip that speaks to the need for a Power Module with 2 - KEM's

Power Information

The Cisco Unified IP Color Key Expansion Module for the Cisco Unified IP Phone 8961, 9951, and 9971 have the following power consumption and power scheme.

Power Consumption

48V DC, 5W per KEM

Power Scheme

At least one KEM can be powered up if the Cisco Unified IP Phone 8961, 9951, and 9971 uses AT PoE.

If the phone uses a power adapter, three KEMs can be powered up for the Cisco Unified IP Phone 9971, two KEMs can be powered up for the Cisco Unified IP Phone 9951, and one KEM can be powered up for the Cisco Unified IP Phone 8961.

A KEM cannot be powered up if the Cisco Unified IP Phone 8961, 9951, and 9971 uses AF PoE.

Cheers!

Rob
