2.

Plug in the one end of UTP cables to the RJ-45 phone jack of adapter.

3. Plug the other end of UTP to normal ports of the switch.

4.

Turn on the PC and check if the Link LEDs on the adapter card and the 

switch (Named as LNK ACT 100/LNK ACT 10) are lit up. See Figure 2-4-1

If the LED is not lit up, there must be something wrong and please

This chapter describes the network topology for hybrid 10 Mbps and 100

Mbps networks, cabling requirement for connections, the interoperability

between hubs and switches. And tell you how to use the ALW-3016 to

expand your port numbers.

3.1 Connecting a hub/switch to normal port

You can use the ALW-3016 as a backbone switch in small and medium

size LAN environment, and for the purpose of expanding your port number

you can connect another hub/switch with it's uplink port to the normal port

of ALW-3016. See Figure 3-1-1

1. Place the hub/switch on a stable surface.

2. Use one end of the UTP/STP cord to connect to the uplink port of the 

hub/switch.

3. Use the other end of the UTP/STP cord to connect to the normal port of 

ALW-3016

4. Check the status of LNK ACT 100/LNK ACT 10 LED. If the LNK ACT 

100 /LNK ACT 10 LED is lit on green then it works normal.

5. Then you can connect the terminal to the new hub/switch
