following main components: network ports, status
indicators and a reset button, as shown below.
Front Panel of the 24-port switch
Front Panel of the 16-port switch
Status indicators:
Every Giga port provides 1 Link/Act Port, 1 100Mbps
indicator, and 1 1000Mbps indicator. The SFP port and
Giga RJ45 port share the same group port indicator: 1
Link/Act, 1 1000Mbps. Besides these, the switch also
has 1 SYS LED indicator, and 1 power indicator. It is
possible to check the switch status by looking at the
orange LED indicators, as shown in the table below:

settings, and restore the switch to its factory default
configuration.
How to use the RESET button:
To restore the default settings, press and hold the
“Reset” button when the switch is on; the indicator will
change from light/blinking/off, then release the “Reset”
button. When the “SYS” indicators relight, it means the
switch has completed the restore.
Pressing the “Reset” button will cause the loss of all
configured values and a new configuration will be requi-
red. Please DO NOT use the “Reset” button if you do not
want to delete all the current settings.
Network ports:
The switch is made up of 16/24
10/100/1000M autonegotiation RJ-45 ports (Ports 1
~ 16/24), which support Auto MDI/MDIX function.
Giga SFP fiber port (shared with the Giga RJ45 port),
supports SFP fiber hot-plugging Giga RJ45 Ethernet port
and Giga SFP fiber port auto-switch.
SFP port is a fiber module interface; you have to insert
the so-called SFP（Mini GBIC）to make the fiber connection
available.
SFP module fiber connection takes priority over the RJ45
Ethernet network connection. The switch will cut off the
RJ45 Ethernet switch connection and will automatically
change from an RJ45 to an SFP fiber interface, when the
SFP fiber connection is found.
Note: The indicator of the SFP goes “on” after about 40
seconds due to the switch initializing process and to the
fiber connection checking.

Network transmission media:
RJ45 ports support CAT5/CAT5 or higher category of
STP/UTP cabling. CAT6 UTP cable is recommended to
ensure stable data transmission at 1000 Mbps.
LC fiber connectors are used for the SFP modules.
Caution!
Make sure that only one uplink connection exists
between switches (except for the Trunk function) or
between the switch and HUB, otherwise the multi-uplink
connection could form a loop that makes the entire
network unstable.

parameters of the switch.
You can log in to the setting window of the switch through
the following steps:
a. Connect the switch with the computer NIC interface.
b. Power on the switch.
c. Check whether the IP address of the computer is
within the 192.168.0.xxx range (“xxx” is the integer
between 2~254), for example, 192.168.0.100. For the
IP address setting, refer to Appendix 2.
d. Open the browser, and enter http://192.168.0.1;
then press “Enter”. The switch login window appears, as
