Power over Ethernet
– 362 –
◆ If a device is connected to a switch port and the switch detects that it requires
more than the power budget set for the port or to the overall switch, no power
is supplied to the device (i.e., port power remains off).
◆ If the power demand from devices connected to all switch ports exceeds the
power budget set for the switch, the port power priority settings are used to
control the supplied power. For example:
■
If a device is connected to a low-priority port and causes the switch to
exceed its budget, power to this port is not turned on.
■
If a device is connected to a critical or high-priority port and would cause
the switch to exceed its power budget as determined during bootup,
power is provided to the port only if the switch can drop power to one or
more lower-priority ports and thereby remain within its overall budget.
■
If a device is connected to a port after the switch has finished booting up
and would cause the switch to exceed its budget, power will not be
provided to that port regardless of its priority setting.
■
If priority is not set for any ports, and there is not sufficient power to supply
all of the ports, port priority defaults to Port 1, Port 2, Port 3 ... Port 24, with
available power being supplied in that sequence.
■
If priority is not set for any ports, and PoE consumption exceeds the
maximum power provided by the switch, power is shut down in the reverse
sequence, starting from Port 24.
Parameters
These parameters are displayed:
◆ Port – The port number on the switch.
◆ Admin Status – Enables PoE power on a port. Power is automatically supplied
when a device is detected on a port, providing that the power demanded does
not exceed the switch or port power budget. (Default: Enabled)
◆ Mode – Shows whether or not PoE power is being supplied to a port. Note that
if power is turned off due to an overload, administrative status will still display
enabled.
