equipment.
Warnings indicate that there is the possibility of injury to person.
Cautions and Warnings appear here and may appear throughout this manual where appropriate. Failure to read
and understand the information identified by this symbol could result in poor equipment performance, damage
to the equipment, or injury to persons.
Caution: While installing or servicing the power supply module, wear a grounding device and observe all
electrostatic discharge precautions. Failure to observe this caution could result in damage to, or failure of the
power module.
Warning: Do not connect the power module to an external power source before installing it into the
chassis. Failure to observe this warning could result in an electrical shock, even death.
Warning: Equipment grounding is vital to ensure safe operation. The installer must ensure that the power
module is properly grounded during and after installation. Failure to observe this warning could result in an
electric shock, even death.
Warning: A readily accessible, suitable National Electrical Code (NEC) or local electrical code approved
disconnect device and branch-circuit protector must be part of the building's installed wiring to accommodate
permanently connected equipment. Failure to observe this warning could result in an electric shock, even death.
Warning: Turn any external power source OFF and ensure that the power module is disconnected from the
external power source before performing any maintenance. Failure to observe this warning could result in an
electrical shock, even death.
Warning: Ensure that the disconnect device for the external power source is OPEN (turned OFF) before
disconnecting or connecting the power leads to the power module. Failure to observe this warning could result
in an electric shock, even death.

LED Descriptions
The LEDs on the front panel provide switch status checking and
monitoring. There are three types of LEDs as follows:
System LED
Indicates if the switch is powered up correctly, indicates if there is a
system alarm triggered for troubleshooting.
Mode LEDs
Indicate the mode of all ports on the switch. You can press the Mode/Reset button sequentially to switch
between the two modes (Link/Activity/Speed mode and PoE mode).
Port Status LEDs
Indicate the current status of each port. You can check these LEDs to understand the port status in different
modes, after changing the mode by pressing the Mode/Reset button.
The LED indicators are described in the following tables.
Table 1: System LED
LED Color State Description

By pressing the Mode/Reset button for certain period of time, you can perform these tasks.
•Change Port Status LED Mode: to read the port status correctly in the two different modes (PoE mode
or Link/Act/Speed mode).
•Reset the Switch: to reboot and get the switch back to the previous configuration settings saved. The First
Time Wizard displays again after pressing the Reset button.
•Restore the Switch to Factory Defaults: to restore the original factory default settings back to the switch.
Note: Based on the table below, you can judge which task is being performed by reading the LED behaviors
while pressing the Mode/Reset button. Once the LED behaviors are correctly displayed, you may release the
button.

Chapter 4 Initial Switch Configuration
Initial Switch Configuration via Web Browser
When you power up the switch the first time, a First Time Wizard is presented. On subsequent power ups, you
can perform the initial switch configuration using a web browser. See the Quick Start Guide for First Time Wizard
information. For managing other switch features, refer to the Web User Guide for details.
For the initial configuration stage, you must 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 via web browser procedure is as follows:
Note: The switch’s factory default IP address is 192.168.1.77 and the factory default Subnet Mask is
255.255.255.0.
1. Power up the PC that you will use for the initial configuration. Make sure the PC has an Ethernet RJ45
connector to be connected to the switch via standard Ethernet LAN cable.
2. Reconfigure the PC’s IP address and Subnet Mask as below, so that it can communicate with the switch.
To change the PC’s IP address for a PC running Windows® 7/8.x/10, is as follows:
a) Type “network and sharing“ into the Search box in the Start Menu.
b) Select Network and Sharing Center.
c) Click on Change adapter settings on the left of PC screen.
Note: You can skip steps a to c, by pressing WinKey+Rand type ”ncpa.cpl” command to get to step d directly.
d) Right-click on your local adapter and select Properties.
e) In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4)
then click the Properties button.
Note: Be sure to record all your PC’s current IP settings to be able to restore them later.
f) Select the radio button Use the following IP address and enter in the IP for the PC (e.g., any IP
address not in use, and in between 192.168.1.2 and 192.168.1.254), Subnet mask (e.g.,
255.255.255.0), and Default gateway that corresponds with your network setup.
Then enter your Preferred and Alternate DNS server addresses.
g) Click OK to change the PC’s IP address.
3. Power up the switch to be initially configured and wait until it has finished its start-up processes.
4. Connect the PC to any port on the switch using a standard Ethernet cable, and check the port LED on
the switch to make sure the link status of the PC is OK.
5. Run your Web browser on the PC; enter the factory default IP address, to access the switch’s Web
interface.
If your PC is configured correctly, you will see the login page of the switch as shown below.
