Resetting the Switch
Should the switch stop working, try resetting the switch. On the connector side panel under the
system LEDs is a reset button. This reset button requires a tool to be pressed.
Figure 14: Reset Button
This button resets both the CPU of the switch device and the CPU of the management module. It
thereby resets all of the ports by bringing them down and powering them up when the button is
pushed. A quick push of this button performs this reset. When the button is held down for 15 sec-
onds the switch is reset and the password is deleted. You will then be able to enter without a pass-
word and make a new password for the user admin.
In the externally managed switch the reset button resets the CPU of the switch device.

DO NOT use a sharp pointed object such as needle or push pin for pressing the Reset
button. Sharp objects can cause damage, use a flat object to push the reset button.
