Restoring the Factory Default
Configuration
(Series 2500 switches only)
As part of your troubleshooting process on the Series 2500 switches, 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, and reboots the switch into its factory default
configuration including deleting the IP address, if one is configured.
N o t e
This process removes all switch configuration changes that you have made
from the factory default settings. This includes, for example, configuration of
VLANs, spanning tree, trunks, and stacking. Returning the configuration of
these features to their factory default settings (usually disabling them) may
result in network connectivity issues.
If the switch has a valid configuration, and you are restoring the factory default
settings for a reason other than configuration problems, you should save the
switch configuration prior to performing the factory default reset. Then, after
the reset and resolution of the original problem, you can restore the saved
configuration to the switch. For both the save and restore processes, you can
use the console
copy
command. See the switch Management and Configura-
tion Guide for more information on this command.
You can restore the factory default configuration either on the switch itself,
or through the switch console.
To execute the factory default reset on the switch, perform these steps:
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 blink, release the Clear button.
The switch will then complete its self test and begin operating with its
configuration restored to the factory default settings.
To restore the factory default configuration using the console, execute the
delete startup config
command from the console command prompt.
