• JavaScripts (enabled by default).
• Java permissions (enabled by default).
Table 68 Troubleshooting the Start-Up of Your Switch
PROBLEM CORRECTIVE ACTION
None of the LEDs
turn on when you
turn on the switch.
Check the power connection and make sure the power source is turned on.
If the error persists, you may have a hardware problem. In this case, you should
contact your vendor.
Table 69 Troubleshooting Accessing the Switch
PROBLEM CORRECTIVE ACTION
I cannot
access the
web
configurator.
The administrator username is “admin”. The default administrator password is
“admin”. The username and password are case-sensitive. Make sure that you enter
the correct password and username using the proper casing. If you have changed the
password and have now forgotten it, you will need to reset the switch to its factory
defaults. Press the RESET button on the front panel of the switch for one second and
the switch automatically reloads its default configuration file. The IP address of the
switch reverts to “192.168.1.1”.
Your computer’s and the switch’s IP addresses must be on the same subnet.
See the following section to check that pop-up windows, JavaScripts and Java
permissions are allowed.
