barox Kommunikation 20Power Management ModeThis is where one defines how the switch should behave should the maximum possible powerlevel be exceeded.- Actual ConsumptionShould the amount of power demanded by the devices exceed the maximum possible amountof power that the switch can provide, PoE is turned off completely. If the power limit is onlyexceeded by one single port, PoE is only turned off to this port.The importance of the individual ports is defined in the “Priority” column. Ports set to “ Low” areturned off immediately, whereas ports set to “Critical” are turned off last s hould the maximumpower level be exceeded.- ReservedPorts set to “Reserved” are only turned off, if the power reserved for them in the“Maximum Power (W)” column is exceeded.PoE ScheduleEach individual port can be allocated to a time schedule. A total of 16 time schedulescan be created.3.11.2. PoE Power DelayAs already mentioned, the switch can provide a limited amount of power.However, today’s IP cameras require an ever-increasing amount of power. If a pan/tilt camerawith an integrated heater and IR emitter is used, the amount of power required will climb evenhigher.When rebooting, switching between day and night mode, turning on the heater or IR emitter etc.,a camera needs considerably more power (peak power supply) than during steady, uninterruptedoperation.Should several cameras connected to one switch all log in at the same time, the maximumamount of power that can be supplied by this switch might be exceeded. Exceeding thismaximum power level will cause the switch to immediately log itself back off and may alsocause damage to the power supply, if numerous unsuccessful attempts are made.To avoid this problem, one can configure the individual ports to start up one after the oth erin the following menu. In the example below, ports 1 and 2 are immediately activated − with2 more ports then being activated every 10 seconds after that.
