Power Management Mode
This is where one defines how the switch should behave should the maximum possible power
level be exceeded.
- Actual Consumption
Should the amount of power demanded by the devices exceed the maximum possible amount
of power that the switch can provide, PoE is turned off completely. If the power limit is only
exceeded 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” are
turned off immediately, whereas ports set to “Critical” are turned off last s hould the maximum
power level be exceeded.
- Reserved
Ports set to “Reserved” are only turned off, if the power reserved for them in the
“Maximum Power (W)” column is exceeded.
PoE Schedule
Each individual port can be allocated to a time schedule. A total of 16 time schedules
can be created.
3.11.2. PoE Power Delay
As 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 camera
with an integrated heater and IR emitter is used, the amount of power required will climb even
higher.
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, uninterrupted
operation.
Should several cameras connected to one switch all log in at the same time, the maximum
amount of power that can be supplied by this switch might be exceeded. Exceeding this
maximum power level will cause the switch to immediately log itself back off and may also
cause 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 er
in the following menu. In the example below, ports 1 and 2 are immediately activated
− with
2 more ports then being activated every 10 seconds after that.
