the power supply can deliver or if the actual power consumption
for a given port exceeds the reserved power of that port. The
ports are shut down according to port priority. If two ports have the
same priority, the port with the highest port number is shut down.
Reserved Power
: the ports are shut down when total reserved
power exceeds the amount of power that the power supply can
deliver. The port power will not be turned on if the power device
requests more power than available from the power supply.
Primary and Backup
Power Source
Some switches support two PoE power supplies. One is used as
primary power source, and one as a backup. If the switch does
not support backup power supply, only the primary power supply
settings will be shown. If the primary power source fails, the
backup power source will take over. To determine the amount of
power allowed for the power device, you must configure the
amount of power the primary and backup power sources can
deliver.
Valid values are in the range 0 to 2000 watts.
Port
The logical port number for this row.
Ports that are not PoE-capable are grayed out and thus unable to
be configured.
PoE Mode
A drop-down list for selecting PoE operations. The modes include:
Disabled
: disable PoE
PoE
: enable PoE IEEE 802.3af (Class 4 PDs limited to 15.4W)
Priority
Indicates port priority. There are three levels of power priority:
Low
,
High
, and
Critical
.
The priority is used when remote devices require more power
than the power supply can deliver. The port with the lowest priority
will be turn off and power will be supplied to the port with the
highest port number.
Maximum Power
Indicates the maximum power in watts that can be delivered to a
remote device (the maximum allowed value is 30 W).
