PHONE POWER CONSUMPTION
This section provides tables with information on telephone power requirements. Use the table
that is relevant to your particular installation.
LOCAL POWER
Table 33 below lists the actual power required by the various telephones. The values in this
table can be used to determine:
• what size UPS would be required to maintain power to the phones in the event of a main
power outage
• if a L2 switch that uses a proprietary PoE (non-802.3af compliant) mechanism has sufficient
power capabilities to power the desired combination of phones.
Notes:
1. The phone power requirements shown in Table 33 do not include the 3300 Power
Dongle power requirements. For example, a 5220 (Dual Mode) phone requires 4.7
watts of power and a 3300 Power Dongle requires 1.4 watts of power. If the 5220
Dual Mode phone is being used in conjunction with a 3300 Power Dongle the power
requirement is 4.7 watts + 1.4 watts for a total power requirement of 6.1 watts.
2. The power values used in Table 33 are based on “maximum worst case” values for
the phones. These values might differ from those shown on a phone data sheet
since the phone data sheets use “typical worst case” values for phone power
consumption.
