Administrator Guide

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 congure 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 eect on the interface. For information about Class Power Management mode, see
Conguring Power Management Mode - Class and Static Mode.
• priority — Enter the keyword priority to congure 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.
• Congure 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.
Example of Setting the Maximum Allocated Power to an Interface
Dell(conf)#interface peGigE ?
PE-ID/UNIT/PORT PE Gigabit Ethernet interface number
Dell(conf)#int peGigE 0/0/1
Dell(conf-if-pegi-255/0/1)#power inline ?
<440-30000> Max milliwatts (default = 30000)
priority Configure poe priority
Dell(conf-if-pegi-0/0/1)#power inline 30000
Example of Setting the Priority to Critical
The following example sets the priority on interface peGigE 255/0/1 to critical.
Dell(conf-if-pegi-255/0/1)#power inline
Dell(conf-if-pegi-255/0/1)#power inline priority ?
critical Critical priority
high High priority
low Low priority (default)
Dell(conf-if-pegi-0/0/1)#power inline priority critical
Example of Displaying PoE Power Allocation on a Port Extender
The following example displays the PoE power allocation to power devices by the port extender, using the show power inline {pe
pe—id stack-unit unit-number | interface interface} command. For a description of the elds, see Displaying PoE
Power Allocation. For information about displaying inline power consumption on a port extender, see Displaying Power Consumption on the
Port Extender.
