Hello,

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

If the phone is powered via POE, you need a power cube for the sidecar. If the phone is powered via a power cube, you would only need another power cube for a second sidecar.
