Cisco Cisco SG200-26P 26-port Gigabit PoE Smart Switch ユーザーガイド

Make sure that any configuration changes made are saved to 
the Startup configuration before exiting from the web-based 
interface by clicking on the Save icon. Exiting before you 
save your configuration will result in all current changes 
being lost the next time the switch is rebooted.

The Getting Started window displays. You are now ready to configure the 
switch. Refer to the 

Cisco 200 Series Smart Switch Administration Guide 

for further information. 

If you cannot access your switch from the web-based interface, the switch 
may not be reachable from your computer. You can test network 
connections by using ping on a computer running Windows:

Open a command window by using Start > Run and enter cmd.

At the Command window prompt enter ping and the smart switch 
IP address. For example ping 192.168.1.254 (the default IP address 
of the smart switch).

If you can reach the switch, you should get a reply similar to the 
following:

Pinging 192.168.1.254 with 32 bytes of data:
Reply from 192.168.1.254: bytes=32 time<1ms TTL=128

If you cannot reach the switch, you should get a reply similar to the 
following:

Pinging 192.168.1.254 with 32 bytes of data:
Request timed out.

No Power:   

Power up the switch and your computer if they are turned off.

Bad Ethernet connection:   

Check the LEDs for proper indications. Check the connectors of the 
Ethernet cable to ensure they are firmly plugged into the switch and 
your computer.
