3 Understanding the Switch Features
PoE Rule
DES-1018P/MP supports many PoE features to guarantee the safety and stability of its PoE power supply.
P
oE Power Budget: DES-1018P/MP has set a limitation of maximum PoE power supply at 80/246.4 (DES-
1018P/MP) watts to protect the Switch and to stabilize the power being transmitted to the PoE devices.
Guard Band: DES-1018P/MP has reserved a 3-watt Guard Band to prevent the power supply from
exceeding the PoE power budget. When the current PoE output has reached 80 or 246.4 watts, the Power
Max LED will light up and the Switch will check the priority of each PoE port. In the meantime, if a new PoE
device is connected, the Switch will cut off the power of the port with a higher port number.
Power Saving
DES-1018P/MP supports IEEE802.3az Energy Efficient Ethernet, which will constantly detect if there is data
being transmitted and will put ports in sleep mode accordingly.
