PoE Enable:
Select to enable or disable the PoE function by ports.
Power Limit:
This function allows you to manually set the port power current limitation to be given to the PD.
To protect the DES-1228P and the connected devices, the power limit function will disable the PoE function
of the port when the power is overloaded. Select from "
Class 1
", "
Class 2
", "
Class 3
" and "
Auto
" for the
power limit. "
Auto
" will negotiate and follow the classification from the PD power current based on the
802.3af standard.
Power over Ethernet (PoE) > PoE System Settings (Only for DES-1228P)
This page will display the PoE status including System Budget Power, Support Total Power, Remainder
Power, and The ratio of system power supply.
Figure 59 – PoE > PoE System Setting
System Power Threshold:
When the ratio of the system power supply is larger than or smaller than the
System Power Threshold Setting, the Switch will send trap events to the Management Station.
Note:
When there is a system power shortage
with the PD, the Switch will enforce the PoE port
priority management. The lower port numbers will
have priority over the higher port numbers. For
example, Port 1 > Port 2 > ... > Port 24.
QoS > 802.1p/DSCP Priority Settings
QoS is an implementation of the IEEE 802.1p standard that allows network administrators to reserve
bandwidth for important functions that require a larger bandwidth or that might have a higher priority, such as
