To prevent false detection, you should disable PoE on the 
ports on the PoE switches that are used to connect to PSEs.

Configuring Your Switch Using the Web-based Interface
To access the switch by using the web-based interface, you must know 
the IP address the switch is using. The switch uses the factory default IP 
address of 192.168.1.254, with a subnet of /24.
When the switch is using the factory default IP address, the System LED

address or an administrator has configured a static IP address, the System 
LED is a steady green (DHCP is enabled by default). 
NOTE If you are managing the switch through a network connection and 
the switch IP address is changed, either by a DHCP server or manually, 
your access to the switch will be lost. You must enter the new IP address 
the switch is using into your browser to use the web-based interface.

STEP 1 Power on the computer and the switch.
STEP 2 Connect the computer to any network port on the front panel of the 
switch. 
STEP 3 Set up the IP configuration on your computer.

the DHCP server is running and can be reached from the
