The auto-negotiation feature of the switching hub allows port 1 to port 8 running at
one of the following four operation modes:
1. 100Mbps full-duplex
2. 100Mbps half-duplex
3. 10Mbps full-duplex
4. 10Mbps half-duplex
Port F1 and F2 can be used as fiber uplink ports for connecting to another fiber
optic device or operation as redundant function. You can easy extend the distance from
2,000m to 100,000m by multimode or single mode fiber cable.
Warning: The RJ-45 ports are shielded data sockets. They can not be used as
telephone sockets. Only R-J45 plugs are allowed to connect these sockets.

Every port has a Link/Activity LED. Steady green (link state) indicated that the port
has good linkage to its associated device. Flashing green indicates that the port is
receiving or transmitting data between its associated devices.
If the port is connected but the Link/Activity LED is dark, check the following items:
1. The switching hub and the connected device’s power are on or not
2. The port’s cable is firmly seated in its connectors in the switching hub and in the
associated device.
3. The connecting cable is good and with correct type
4. The connecting device, including any network adapter is functioning.
From the Speed LED and Link/Activity, we could judge the connection speed as
following:
