(1) RJ45 Ports
Figure 1-1 Front Panel
There are nine 10/100/1000M RJ45 ports, of which port 9 is the Normal/Uplink
port, others are downlink ports. From port 1 to 4 of the downlink ports are
PoE-capable, port 5 to 8 of the downlink ports are regular ports, details shown as
Table 1-1.
Table 1-1 PoE-capable Ports
Tips: PoE implements two ways of supplying DC power over the RJ45 Ethernet
cable. In Mode-A, is also known as "Phantom Power", the wire pairs which are used for
data transmission are also used to provide the power
(Pair 1 and 2, Pair 3 and 6).
You’re recommended to use Cat.5 or higher UTP/STP cables.
(2) LED
You can check link status and activity of the switch via LEDs.
Table 1-2 describes the LED status.
PoE-capable Ports (1 ~ 4)
Compliant with the IEEE 802.3af and IEEE 802.3at standards
Up to four IEEE 802.3af compliant (15.4W per port) or two IEEE 802.3at
compliant (30W per port) powered devices (PDs) can be accessed
simultaneously connected on any PoE-capable port
