1 INTRODUCTION
1.1 Unpacking
Open the box and carefully unpacks its
contents. The box should contain the
following items:
One Switch
4
rubber pads
One external power adapter (only 5/8 ports
switch)
User’s Guide.
If any item is found missing or damaged,
please contact your dealer for replacement.
1.2 Front Panels
For detail of the LED indicators in the front
panel of the switch, refer to the LED Indicator
section for detailed information about each of
the 5/8/16/24 ports switch’s LED indicators.
1.3 Rear Panel
There are 24/16/8/5 10/100Mbps MDI-X port
Jacks and one DC Power Jack in.
1.4 LED Indicators
The LED indicators of the Switch include
Power 、Link/ACT and 100M. The LED
indicators are used to facilitate monitoring and
troubleshooting of the Switch. The following
shows the LED indicators for the Switch along
with explanation of each indicator.

1.5 Features
The 5/8/16M/24 ports switch combines large
dynamic memory allocation with store-and
forward switching to ensure that the buffer is
effectively allocated for each port, while
controlling the data flow between the transmit
and receive nodes to guarantee against all

possible packet loss. The 5/8/16/24 ports switch
can detect 10M/100M and full duplex/half
duplex mode.
The 5/0/16/24 ports switch is not a
managed switch, but it is very easy to use, and
it can accelerate small Ethernet
workgroup bandwidth.
2 PERFORMANCE FEATURES
1、24/16/8/5 UTP/STP ports, and auto-
negotiation for any port. This allows for
auto sensing of speed (10/100Mbps) there
by providing you with automatic and
flexible solutions in your network
connections.
2、Store-and-forward switching to ensure that
the buffer is effectively allocated for each
port.
3、Data filtering rate eliminates all error
packets. Packet Filtering/Forwarding Rate
is 148800bps per port at 100% 100Mbps
wire-speed and 14880bps per port at 100%
10Mbps wire-speed.
4、5K MAC address entries table per device
for the 5/8/1/24 ports switch.
5、2MB RAM buffer.
6、Support IEEE802.3x for full duplex mode
operation, support backpressure for half
duplex mode operation.

3 INSTALLATION
Convenience receptacle and equipment should
be within 1.82 meters.

Check power supply is confirmed the safe
Connection.
Affirms to have the ventilation that is enough,
can be very good dissipates heat. Not lay up the
heavy object on switch.
3.1 Desktop Installation
When on the top of a table installing the
switch, the rubber pad of equipment bottom
touches ground first. There is the ventilation space
that is enough between the body of equipment and
vicinity.
3.2 SWITCH to PC
A PC can be connected to the 5/8/16/24
via a two-pair Category 3, 4, 5 UTP/STP
straight cable. The PC can be connected to any
of the 8 ports (1x - 8x).
The LED indicatorsfor PC connection
depend on the LAN card’s capabilities. If LED
indicators are not lit after making a
properconnection, check the PC LAN card, the
cable and the switch conditions and
connections.
The following are LED indicator
possibilities for a PC to connection:
1. The “100”LED indicator lights green
for hookup to 100Mbps speed or
distinguish for 10Mbps speed.
2. The “Link/Act” LED indicator lights
while connection established.

3.3 HUB to Switch
The switch can link with the hub (switch)
by way of two (UTP/STP) straight cables
twisting of a 3,4,5 and the connection is
accomplished from the hub uplink (MDI-II) port
to any of the 5/8/16/24 ports switch (MDI-X)
ports.
10BASE-TX HUB
Connect to 10BASE-TX HUB ，the LED
indicator shows follow：
100M LED Extinguishes
Link/Act LED lights
100BASE-TX HUB
Connect to 100BASE-TX HUB ，the LED
indicator shows follow：
100M LED lights
Link/Act LED lights
3.4 HUB (SWITCH) without Uplink (MDI-II) port
If a HUB or SWITCH is not equipped
with an uplink (MDI-II) port, you can use
straight cable and crossover cable (please refer
the appendix).
4 APPENDIX
RJ-45 PIN SPECIFICATION
When connecting your switch to another
switch, a bridge or a hub, a modified crossover
cable is necessary. Please review these products
for matching cable pin assignment.
