Hi All,

I have 2 questions about expansion module 7915. the first is how i can active the screen light? the second is : the expansion module 7915 can get the power by PoE from IP Phone?

thanks in advance

you have to supply power to the side card through a power cube and connect it up  with an AUX lead to the main phone.Check overview section here for the compatibility and here is a good thread about configuration

Hi Preranda,

So we can't supply it directely from IP Phone by PoE (AUX Lead)?

Hi Maussa,

To make is simpler:

1 IP phone  with POE + 1 7915 module = need power adapter

1 IP phone  with local power + 1 7915 module =no additional power cube.

1 IP phone  with POE or local + 2 7915 module = Definitely need power cube

Hi Moussa,

As per the datasheet of 7915

Table 7. Power Requirements

Number of Cisco Unified IP Phone Expansion Module 7915 Modules	Cisco Unified IP Phone 7962G, 7965G, and 7975G Models Power Source	Items to Order
1	In-line	1 Cisco Unified IP Phone Expansion Module 7915 1 single footstand 1 power cube 1 country cord
1	Local power (cube) *	1 Cisco Unified IP Phone Expansion Module 7915 1 single footstand
2	In-line or local **	2 Cisco Unified IP Phone Expansion Module 7915s 1 double footstand 1 power cube 1 country cord

* A single Cisco Unified IP Phone Expansion Module 7915 can receive power from a locally powered Cisco Unified IP phone.

** Local power must be connected to the first Cisco Unified IP Phone Expansion Module 7915 to supply power to both Cisco Unified IP Phone Expansion Module 7915 modules.
