Upgrading BootROM

Accessing the
BootROM menu
To use the configuration, use the following command:
use configuration [primary | secondary]
The configuration takes effect on the next reboot.
If the switch is rebooted while in the middle of a configuration save, the
switch boots to factory default settings. The configuration that is not in
the process of being saved is unaffected.
To return the switch configuration to factory defaults, use the following
command:
unconfig switch
This command resets the entire configuration, with the exception of user
accounts and passwords that have been configured, and the date and
time.
To reset all parameters except the date and time, use the following
command:
unconfig switch all
The BootROM of the switch initializes certain important switch variables
during the boot process. If necessary, BootROM can be upgraded, after
the switch has booted, using TFTP. In the event the switch does not boot
properly, some boot option functions can be accessed through a special
BootROM menu.
Upgrading BootROM is done using TFTP (from the CLI), after the switch
has booted. Upgrade the BootROM only when asked to do so by a 3Com
technical representative. To upgrade the BootROM, use the following
command:
download bootrom <ip_address>
Interaction with the BootROM menu is only required under special
circumstances, and should be done only under the direction of 3Com
Technical Support. The necessity of using these functions implies a
non-standard problem which requires the assistance of 3Com Technical
Support.
