1 Power LED
Green
Indicates that the Switch is powered on. If the LED is
off, but the Power Adapter OK LED is lit, there may be
a problem with the Switch’s internal power supply.
Refer to Problem Solving.
2 Five/Eight/Sixteen Port Status LEDs
Blue (1000 Mbps link) / Green (100 Mbps link) / 
Yellow (10Mbps link)
If the LED is on, the link between the port and the next
piece of equipment is OK. If the LED is flashing, the
link is OK and data is being transmitted or received. If
the LED is off, nothing is connected or the connected
device is turned off, or there is a problem with the
connection (refer to the Problem Solving section).
3 Duplex LEDs
Yellow (10/100/1000 Mbps, full duplex) / 
Off (10/100 Mbps, half duplex)
4 Power Adapter Socket
Only use the power adapter that is supplied with the
Switch.
5 Power Adapter OK LED
Green
Indicates that the power adapter is supplying power to
the Switch. If the LED is off, there may be a problem
with the power adapter or adapter cable (refer to
Problem Solving).
6 10BASE-T/100BASE-TX/1000BASE-T Ports
Use suitable TP cable with RJ-45 connectors. You can
connect your Switch to a workstation, or any other
piece of equipment that has 10BASE-T/100BASE-TX/
1000BASE-T connectivity.
Each port is capable of autosensing for 10 Mbps, 
100 Mbps or 1000 Mbps operation.
All ports have an automatic MDI/MDIX feature, which
means either straight-through or crossover cable can
be used to connect to any port.
