Switches
System Reset Button
This button will reset the entire switch, including the second management
module, when powered on. This action clears any temporary error conditions
that may have occurred, executes the switch self test, and resets all network
activity counters to zero. The counters are displayed in the switch console
interface, the switch web browser interface, and through SNMP network
management applications, such as Intelligent Management Center.
Press the Reset button also after changing the module type that is installed in
any of the switch module slots while the switch is powered on. See “Hot
Swapping Switch Modules” on page 2-28.
You can also use the no module <slot> command to erase the old module type
configuration.
Clear Button
This button is used for the following purposes:
■ Deleting Passwords - When pressed for at least one second on either
one of the Management Modules, the Clear button deletes any switch
console access passwords that you may have configured. Use this feature
if you have misplaced the password and need console access.
This button is provided for your convenience, but its presence means that
if you are concerned with the security of the switch configuration and
operation, you should make sure the switch is installed in a secure
location, such as a locked wiring closet.
■ Restoring Factory Default Configuration - When pressed with the
Reset button in a specific pattern, the Clear button clears any configura-
tion changes you may have made through the switch console, the web
browser interface, or SNMP management, and restores the factory default
configuration to the switch. The specific patterns to accomplish the
Restore Factory Default Configuration are:
i. Press both the System Reset and Clear buttons simultaneously.
ii. Release the System Reset button, but continue to hold the Clear
button.
iii. Release the Clear button immediately when you see the Test LED
begins to flash on both the Management Modules.
For the specific method to restore the factory default configuration, see
“Restoring the Factory Default Configuration” in chapter 4, “Troubleshooting”
of this manual.
