3.6  Initialization
After the device is powered on, it begins the Power-On Self-Test. A series of tests  run automatically 
to ensure the device functions properly. During this time, its LED indicators will respond in the 
following order:
1.  The PWR LED indicator lights on all the time. The SYS LED and the LED indicators of all the ports 
keep off.
2.  After about one minute, the SYS LED and LED indicators of all the ports will flash momentarily and 
then turn off. 
3.  Several seconds later, the SYS LED indicator will flash, which represents a successful initialization.
3.7  Accessing the Switch
After the initialization finished, you can access and manage the switch using the GUI (Graphical User 
Interface) or using the CLI (Command Line Interface). 
 ■
To access the switch using the GUI, open a web browser and type the default management address 
http://192.168.0.1 in the address field, then press the Enter key. The default Username and Password 
are both admin in lower case letters.
 ■
To access the switch using the CLI, you can use the Console port, Telnet and SSH connection. When 
using the Console port, start the terminal emulation program (such as the Hyper Terminal) on the PC 
and configure the terminal emulation program as follows:
Baud Rate Data Bits Parity Stop Bits Flow Control
