Restoring the factory-default configuration
As part of your troubleshooting process, it may become necessary to return the switch configuration
to the factory default settings. This process
• Momentarily interrupts the switch operation
• Clears any passwords
• Clears the console Event Log
• Resets the network counters to zero
• Performs a complete self test
• Reboots the switch into its factory default configuration, including deleting an IP address
There are two methods for resetting to the factory-default configuration:
• CLI
• Clear/Reset button combination
NOTE: HP recommends that you save your configuration to a TFTP server before resetting the
switch to its factory-default configuration. You can also save your configuration via Xmodem to a
directly connected PC.
Resetting to the factory-default configuration
Erase start-up config
This command operates at any level except the Operator level.
Syntax
erase startup-configuration
Deletes the startup-config file in flash so that the switch will reboot with its
factory-default configuration.
NOTE: The erase startup-config command does not clear passwords
unless include-credentials has been set, at which time this command does
erase username/password information and any other credentials stored in the
config file.
Using Clear/ Reset
1. Using pointed objects, simultaneously press both the Reset and Clear buttons on the front
of the switch.
2. Continue to press the Clear button while releasing the Reset button.
3. When the Self Test LED begins to flash, release the Clear button.
The switch then completes its self test and begins operating with the configuration restored to
the factory default settings.
Zeroization
The zeroization feature is used to restore the switch to its default, factory state. This is accomplished
by sanitizing the persistent storage media (compact, SD, flash, etc..) Zeroization removes all
customer installed/altered files, including the following:
• switch configurations (including manager/operator credentials)
• system generated public keys
