xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide
Power Limit (1-370)
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 37W and 370W for the DES-3528P/DES-3552P. The
default setting is 370W.
Power Disconnect
Method
The PoE controller uses either
Deny Next Port
or
Deny Low Priority Port
to offset the power
limit being exceeded and keeps the Switch’s power at a usable level. Use the drop-down
menu to select a Power Disconnect Method. The default 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. If Power Disconnection Method is set to
Deny Next
Port
, the system cannot utilize out of its maximum power capacity. The maximum unused
watt is 19W.
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 so as to allow the high-
priority and critical priority ports to power up.
Legacy PD
Use the drop-down menu to enable or disable detecting legacy PDs signal.
