Button Action
Reset Performs a software and hardware reset, including a hardware self-test. (This
achieves the same result as disconnecting the power from the switch, then
reconnecting it.)
Config When used as described below, causes the switch to delete the current
Clear configuration, and to reboot to a default configuration based on the installed
modules and transceivers. This resets the switch to the factory default and is
a drastic action that interrupts switch operation and can seriously diminish or
even halt network operation. Depending on the current network operating
condition, it may be best to avoid a reset until you can schedule system
downtime. Some reasons for a reset include:
• The switch appears to be malfunctioning, and pressing just the Reset button
does not clear the problem.
• Several elements in the configuration may be inconsistent with each other
and it is more efficient to start with the defaults than to try to adjust individual
parameters.
Effects of a reset to the factory default:
• Clears all passwords.
• Configures the switch as a multiport transparent bridge with Bootp enabled.
The switch then transmits Bootp requests until either a Bootp reply is
received or the retransmission timeout of approximately 1 minute is reached.
(If the switch receives a reply from a Bootp server, the switch restarts itself
for operation according to the configuration received from the Bootp server.
Refer to appendix E, "Bootp Operation".)
• Returns all configuration parameters to their factory default settings. (Turns
off the Spanning Tree Protocol.)
• Clears the event log.
• Runs the system self-test.
To clear the current configuration and reboot the switch:
1. Press and release the Reset button. All LEDs turn on momentarily.
2. While all LEDs are turned on, press and hold the Config Clear button until the
Self-test LED begins flashing, then immediately release the Config Clear button.
If a console is connected, you will see the following message when the switch
has reset itself to the factory default configuration and rebooted.
Waiting for speed sense. Press enter to continue.
3. Press [Enter] to restart the console.
To clear the password(s)
Press and release the Config Clear button.
