Patent ID: 7904115

Claim:
A telecommunication apparatus having a plurality of traffic handling units, and a plurality of power supply units for powering the plurality of traffic handling units, comprising: a control means adapted to receive input information on a power criterion so as to determine a power budget for the plurality of power supply units and plurality of traffic handling units based on the power criterion wherein the power budget is determined by: determining the power requirement for maximum traffic handling of all the traffic handling units, determining the maximum available power from all the power supply units. calculate a power criterion that includes the power requirement for maximum traffic handling of all the traffic handling units and the maximum available power from all the power supply units, and set the power budget based on the power criterion; and the control means operable to activate an amount of traffic handling units of the plurality of traffic handling units having a total power consumption equal to or less than the power budget; and the control means operable to activate an amount of power supply units of the plurality of power supply units matching the total power consumption of the amount of activated traffic handling units, wherein the control means are operable to transfer active traffic from a traffic handling unit which is to be de-activated, to one or more of the other activated traffic handling units, before de-activating the to be de-activated traffic handling unit.
