19.4 Po E
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power over
Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides a source of
power through its Ethernet ports, and each device that receives power through an Ethernet port is a
Powered Device (PD).

PoE Mode Select the power management mode you want the Switch to use.
• C la ssific a tion – Select this if you want the Switch to reserve the maximum power for each PD
according to the PD’s power class and priority level. If the total power supply runs out, PDs
with lower priority do not get power to function. In this mode, the maximum power is
reserved based on what you configure in Ma x Po we r or the standard power limit for each
class.
• C onsump tion – Select this if you want the Switch to supply the actual power that the PD
needs. The Switch also allocates power based on a port’s Ma x Po we r and the PD’s power
class and priority level. The Switch puts a limit on the maximum amount of power the PD can
request and use. In this mode, the default maximum power that can be delivered to the PD
is 33 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af Classes 0 to 3).
Pre-Allocate This field is only available on GS1900-8HP (Revision B1) and GS1900-10HP only.
Select Ena b le to have the Switch pre-allocate power to each port based on the classification of
the PD device. Otherwise, select Disa ble .
