DGS-6604 m poe power-inline poe power-inline Use this command to configure the power management mode on the Power over Ethernet (PoE) ports. poe power-inline { auto | never | static [ max MAX-WATTAGE ] } [ time-range] [PROFILE-NAME ] Syntax Description auto Enable powered-device detection. If enough power is available, automatically allocate power to the PoE port after device detection based on IEEE802.3af. never Disable device detection, and disable power to the port. static Disable powered device detection. The power quantity which allowed to the port is configured by user manually. max MAX-WATTAGE (Optional) Limit the power allowed on the port. The unit is milli-watt (mW). The range is 4000 to 17000 mW. If no value is specified, the maximum is allowed. time-range PROFILE- (Optional) Specifies the name of time-range profile associated with the per-port NAME power-inline configuration delineating its activation period. If no PROFILE-NAME is specified, that means to remove the time-range binding of the port instead of disable the PoE functionality. Default Command Mode Usage Guideline The default mode is never (disabled). The default power threshold value in auto mode is 16.2W, 4.2W, 7.4W and 16.2W for class-0, class-1, class-2 and class-3 respectively. The default maximum power threshold in static mode is 17000 mW. Interface configuration. This command is supported only on PoE-capable ports. If you enter this command on a port that does not support PoE, an error message appears to indicate the corresponding message. Under the static mode, if the powered device requesting more power than the maximum power threshold, the switch removes power from the port, and the port state will be set to "faulty" to indicate the error If the powered-device IEEE class maximum is greater than the maximum wattage, the switch does not power the device. The power is reclaimed into the global power budget. In auto mode configuration, the power threshold is configured by the PoE chip itself, and the value will be 16.2W, 4.2W, 7.4W and 16.2W for class-0, class-1, class-2 and class-3 respectively. These threshold value will also used as the allocated power for that port. The maximum power threshold value in static mode is designed as 17W. The reason is, the actual voltage which PSE side output and the actual current which PD drains will both have the tolerance inaccuracy. Generally, the tolerance is 5%. Thought, in the worst case, the actual power which PSE needs to offer will be 1.1025(1.05*1.05) times of maximum power consumption (15.4W) defined in CLI Reference Guide 470
