Dell C1048P Port Extender Networking Configuration Guide for the C9000 Series - Page 735

NOTE: Avoid allocating more power than necessary to a port because allocated power is made unavailable to other ports regardless of whether it is consumed when using the power inline max_milliwatts command. Typical IP phones use 3 to 10 Watts. The power inline command has the following parameters: • max_milliwatts - (OPTIONAL) Specify the maximum inline power that is allocated to a powered device connected to the interface. The range if from 440 to 30000 mW. When you do not configure a power value, the system uses the default value (30000 mW). NOTE: The max_milliwatts option only works when you use Static Management mode. When you enable Class mode, the max_milliwatts option has no effect on the interface. For information about Class Power Management mode, see Configuring Power Management Mode - Class and Static Mode. • priority - Enter the keyword priority to configure the powered device to connect to the interface. • critical - Enter the keyword critical to set the PoE priority level as critical. • high - Enter the keyword high to set the PoE priority level as high. • low - Enter the keyword low to set the PoE priority level as low. By default, all ports are set to low priority. • Configure the maximum power allocation and priority for the powered device connected to a port extender interface. Interface Mode power inline {[max_milliwatts] | priority {critical | high | low}} The following example sets the maximum allocated power to interface peGigE 255/0/1 3000 mW.
