The following parameters can be configured:
Parameter Description
Unit
Choose the switch in the switch stack for which to configure the PoE settings.
Users should note that not all switches in the xStack
®
DGS-3400 Series support PoE yet,
when they are configured in a stack, the Primary Master switch will display the PoE settings to
be configured for the stack, whether or not the Switch is a PoE supported device. However,
only PoE supported switches have the PoE capability in the switch stack.
Power Limit (37-
370W)
Sets the limit of power to be used from the Switch’s power source to PoE ports. The user may
configure a Power Limit between 37 and 370W for the DGS-3426P. The default setting is
370
W.
Disconnect Method
The PoE controller uses either
Deny next port
or
Deny low priority port
to offset the power limit
being exceeded and keep the Switch’s power at a usable level. Use the drop-down menu to
select a Disconnect Method. The default for the Power Disconnect Method is
Deny next port
.
Both Power Disconnection Methods are described below:
Deny next port
– After the power limit has been exceeded, the next port attempting to power
up is denied, regardless of its priority.
Deny low priority port
–
After the power limit has been exceeded, the next port attempting to
power up causes the port with the lowest priority to shut down to allow the high-priority and
critical priority ports to power up.
Management Mode
Use the drop down menu to select the management mode.
Power Limit
– Specifies that the previously set power limit will be implemented.
Auto
– Specifies that system will automatically determine the management mode.
Click
Apply
to implement changes made.
