Restoring the Factory Default Configuration

Testing End-to-End Network Communications

Both the switch and the cabling can be tested by running an end-to-end
communications test -- a test that sends known data from one network device
to another through the switch. For example, if you have two PCs on the
network that have LAN adapters between which you can run a link-level test
or Ping test through the switch, you can use this test to verify that the entire
communication path between the two PCs is functioning correctly. See your
LAN adapter documentation for more information on running the a link test
or Ping test.
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 momen-
tarily 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
an IP address.
To execute the factory default reset, perform these steps:
1.
2.
3.
3-10
Using pointed objects, simultaneously press both the Reset and Clear
buttons on the front of the switch.
Continue to press the Clear button while releasing the Reset button.
When the Self Test LED begins to flash, release the Clear button.
The switch will then complete its self test and begin operating with the
configuration restored to the factory default settings.
