Fronts of the Switches
Reset and Clear Buttons
The Reset and Clear buttons are located behind the front panel (to protect
them from being pushed accidentally) and are accessible through small holes
in the lower left corner of the front panel. Use pointed objects, such as unbent
paper clips, to push them.
The Reset and Clear buttons are used singly or in combination, as follows:

as data transfer completion, temporary error conditions
are cleared), then reboots and runs self tests.

Press and hold the Reset button for
more than 5 seconds (until all LEDs

unknown state or not responding.

Note: These buttons are provided for your convenience. If you are concerned with switch security though, you should
make sure that the switch is installed in a secure location, such as a locked wiring closet. You can also disable these
buttons by using the front-panel-security command. See the E3800 Management and Configuration Guide for a
description of that command.
