Diagnostic Tips

Testing the Switch by Rebooting It

If you believe the switch is not operating correctly, you can reboot the switch to test its circuitry and operating 
code. To reboot the switch, unplug and plug in the power cord (power cycling).

Power cycling the switch will cause the switch to perform its power-on self test. Rebooting the switch can also 
be invoked from the Web interface.

Restoring to Factory Defaults

If you forget the switch IP address or password, you can restore the factory default configuration by pressing 
the Reset button.

To execute the factory default reset on the switch, perform these steps:

1.

Using a small, thin tool with blunt ends (such as a paper clip), press the Reset button on the front of the 
switch.

2.

Continue to press the Reset button for more than 5 seconds.

3.

Release the Reset button.

The switch will then complete its self test and begin operating with its configuration restored to the factory 
default settings.

After completing this procedure, there will be no password, the IP address will be returned to the default 
192.168.1.1, and all configuration settings will be returned to factory defaults.

Problem

Solution

1

PoE oversubscription condition. All available PoE 
power is already taken by higher-priority ports.

If possible add additional PoE power, or redefine port 
priorities. 

2

PoE hardware fault. A switch hardware component 
that is involved with PoE power delivery has failed.

The switch must be replaced.
