Troubleshooting
NOTE: POST failures are usually fatal. If your switch does not pass POST, you must contact HP. Refer
to the “Where to Go for Additional Help” section in this guide for contact information.
Clearing the Switch IP Address and Configuration
If you have configured a new switch with a wrong IP address, or if all switch LEDs start
blinking when you are trying to enter Express Setup mode, you can clear the IP address that
is configured on the switch.
NOTE: This procedure clears the IP address and all configuration information stored on the switch. Do
not follow this procedure unless you want to completely reconfigure the switch.
To clear the IP address and the switch configuration information, follow these steps:
1. Press and hold the Mode button. The switch LEDs begin blinking after about 2 seconds.
NOTE: If the switch is not configured, the LEDs are all green. You can omit Step 2 and run Express
Setup to configure the switch.
2. Continue holding down the Mode button. The LEDs stop blinking after 8 additional
seconds, and then the switch reboots.
NOTE: These steps only work on a previously configured switch.
The switch now behaves like an unconfigured switch. You can configure the switch by using
Express Setup as described in Appendix E, “Configuring the Switch Using Express Setup”.
You can also configure the switch by using the command-line interface (CLI) setup
procedure described in Appendix D, “Configuring the Switch Using CLI”.
