Gigabit Unmanaged Switch
The 8 ports also support PoE function which integrates power and data onto
one Ethernet cable. Once the device you connect to the switch is identified,
the switch will supply power through the PoE port, and then you can use it as a
10/100/1000Mbps Auto-Negotiation RJ45 Ethernet port. The working status can be
indicated by the PoE MAX LED and PoE Status LEDs on the front panel.

06 Introduction
Note:
Make sure the PDs you connected to the switch are compliant with
■
IEEE802.3af/IEEE802.3at standard.
If all PoE PDs power consumption is ≥126W, a priority* will be arranged among
■
the PoE ports like port 1 > port 2 > port 3 > port 4 > port 5 > port 6 > port 7 >
port 8, then the system will cut off the power of the lowest-priority port.
*Priority is to protect the system when the system power is overloaded. For
■
example, Port 1, 2, 4 and 7 is using 30; the system power is 120W in total. If
there is an additional PD inserted to Port 3 with 25W, and then the system will
cut off the power of Port 7 because of the overloaded power, this means Port 1,
2 and 4 will use 30W, and Port 3 will use 25W, no power will be supplied to Port 7.
