LED Descriptions
The LEDs on the front panel provide users with switch status checking and
monitoring. There are three types of LEDs as follows:
System LED
indicates if the switch is powered up correctly or not, or, indicates if
there is a system alarm triggered for troubleshooting.
Mode LEDs
indicates the mode of all ports on the switch. Users can press the
Mode button sequentially to switch amongthe two different modes
(Link/Activity/Speed mode and PoE mode).
Port Status LEDs
indicates the current status of each port. Users can check these LEDs
to understand the port status in different modes, after changing the
mode by pressing Mode button.
The following table details the functions and descriptions of variousLED
indicators.

Four adhesive rubber feet
Installation Guide
Mounting kit(Option)
Note:
The switch is an indoor device. If it is to be used with outdoor devices
such as outdoor IP cameras or outdoor WiFi APs, then users are strongly
suggested to install a surge protector or surge suppressor in order to
protect the switch.
Mounting the Switch in a 19-inch Rack
Step1: Attach the mounting brackets to both sides of the chassis.
Insert screws and tighten then with a screwdriver to secure the
brackets.

Chapter 3 Initial ConfigurationofSwitch
Initial Switch Configuration Using Web Browsers
After powering up the switch for the first time, you can perform the initial
switch configuration using a web browser. For managing other switch
features, please refer to the Web interface user guide for details.
To begin with theinitial configuration stage, you need to reconfigure your
PC’s IP address and subnet mask so as to make sure the PC can
communicate with the switch. After changing PC’s IP address (for example,
192.168.1.250), then you can access the Web interface of the switch using
the switch’s default IP address as shown below.
The initial switch configuration procedure is as follows:
Note:
The factory default IP address of the switch is 192.168.1.1
The factory default Subnet Mask of switch is255.255.255.0

Causes
Suggested Solutions
SYSTEM LED is
Off
The switch is
not receiving
power.
1. Check if correct power cord is connected firmly
to the switch and to the AC outlet socket.
2. Perform power cycling the switch by unplugging
and plugging the power cord back into the switch.
3. If the LED is still off, try to plug power cord into
different AC outlet socket to make sure correct AC
source is supplied.
SYSTEM LED is
RED
An abnormal
state has been
detected by
the switch.
Check the system log within the switch from
WEB UI to understand the abnormal state
(e.g. exceeding operating temperature
range) and take corresponding actions to
resolve.
Port Status LED
is Off in the
Link/Act/Speed
Mode
The port is not
connected or
the connection
is not working.
1. Check if the cable connector plug is firmly
inserted and locked into the port at both the
switch and the connected device.
2. Make sure the connected device is up and
running correctly.
3. If the symptom still exists, try different cable or
different port, in order to identify if it is related to
the cable or specific port.
4. Check if the port is disabled in the configuration
settings via WEB user interface.
