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
reference to Chapter 4 for quick trouble shooting.

Table 2-5-1 LEDs definition
2.5.1 System indicators
PWR: When the power is connected rightly, the PWR LED will be lit on
Green. If the LED is not lit on, then you should check the connection of
your power and the outlet of power.
Fan Err.: When the fan malfunction at work, then the Fan Err LED will be
lit up and blink. And when the fan is fail, the LED will be lit without blinking.
You should check you fan and your vender and have a new fan to instead
of the old one to make sure the equipment will work normally.
Note: There are two Fan inside the ALW-3016. Fan Err1 & Fan Err2 indicate the two
Fans individually.
2.5.2 Port indicators
LNK ACT 100/LNK ACT 10: When the port is linked with 100Mbps device,
the LNK ACT 100/LNK ACT 10 will be lit on GREEN, or it will be lit on
orange with 10Mbps device.And when there's any transmission activity in
the port, the LED will be blinking in GREEN with 100Mbps or in orange
with 10Mbps. If the port is linked, and the LED isn't lit up, please check if
the port connector fasten tightly.
FDX: When the port is connected with full duplex, it will be lit up on
GREEN. Others it will be DARK.

3. Apply a feasible networking
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
3. Use the other end of the UTP/STP cord to connect to the normal port of
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

Fan Err. LED is
blinking or down
The fan is dead or work
LNK LED of a
connected port
is off.
1.The UTP cable is not
securely connected
2.The port is bad
3.If the other party is a PC,
the Network Interface
Card (NIC) could be not
4.If the other party is
a hub or LAN switch,
the connected ports signal
could be cross-over
1. Check if the power adapter
plug is securely fastened into the
AC outlet.
2. Contact you vender if still
1. Check your fan, maybe you
should have a new fan.
2. Contact the vender
1. Check the cable connection
2. Try to connect another port
3. Check if the network interface
card (NIC) were installed
4. Make sure ALW-3016 normal
port is connected to the other
hub's (or switch's) uplink port,
and ALW-3016 uplink port is
connected the other's normal port.
100 LED is not lit
when connected
to a 100 NIC or
100Hub (but LNK
LED is lit.)

5.The UTP cable is broken,
or it is cross-overed cable.
The auto-negotiation
function is failed between
ALW-3016 and the other
5. Try another normal cable.
1. Check if you force the connection
equipment in specific mode.
If, yes, then free it to auto-negotiation
2. Un-plug the UTP cable from
ALW-3016 and plug-in again.
3. Check if the NIC is setted to
auto-negotiation mode.
4. Check if the other hub is set
to auto-negotiation mode
5. If the above steps does not
work, it is an interoperability
