Recovering a Switch

5.The force PROM menu displays several recovery options. To select a switch recovery option, press the corresponding number (displayed in option: field) on the keyboard and press the Enter key.

0)Exit

1)Image Unpack

2)Reset Network Config

3)Reset Password File

4)Copy Log Files

5)Remove Switch Config

6)Remake Filesystem

7)Reset Switch

Option:

These options and their use are described in the following sections.

5.3.1

Force PROM – Exit

This option closes the current login session. To log in again, enter the force PROM mode account name and password (prom, prom).

5.3.2

Force PROM – Image Unpack

This option unpacks and installs new firmware when the current firmware has become corrupt. Before using this option, you must load the new firmware image file onto the switch. The steps to install new firmware using this option are as follows:

1.Place the switch in force PROM mode. Refer to the procedure for force PROM mode in ”Recovering a Switch” on page 5-9.

2.Use FTP to load a new firmware image file onto the switch. Refer to ”Using FTP and the CLI to Install Firmware” on page 4-16. Do not unpack the firmware image file with the Image command.

3.Select option 1 from the force PROM menu. When prompted for a file name prompt, enter the firmware image file name.

Image filename: filename

Unpacking ’filename’, please wait...

Unpackage successful.

4.Select option 7 to reset the switch and exit force PROM mode.

5.3.3

Force PROM – Reset Network Config

This option resets the network properties to the factory default values and saves them on the switch. Refer to Table B-6for the default network configuration values.
