Upgrading and Accessing BootROM

To display scheduled download information, use the following command:
show switch
To cancel scheduled incremental downloads, use the following command:
download configuration cancel

Remember to Save

Regardless of which download option is used, configurations are downloaded into switch runtime
memory, only. The configuration is saved only when the command is issued, or if the
save
configuration file, itself, contains the command.
save
If the configuration currently running in the switch does not match the configuration that the switch
used when it originally booted, an asterisk (*) appears before the command line prompt when using the
CLI.

Upgrading and Accessing BootROM

The Summit 300-48 switch has a two-stage BootROM. The first stage, called bootstrap, does basic
initialization of the switch processor and will load one of two second-stage bootloaders (called primary
and secondary).
In the event the switch does not boot properly, both bootstrap and bootloader will allow the user to
access the boot options using the CLI.
If necessary, the bootloader can be updated, after the switch has booted, using TFTP.

Upgrading Bootloader

Upgrading Bootloader is done using TFTP (from the CLI), after the switch has booted. Upgrade the
BootROM only when asked to do so by an Extreme Networks technical representative. To upgrade the
BootROM, use the following command:
download bootrom [<hostname> | <ipaddress>] <filename>] [ bootstrap | diagnostics |
primary_bootloader | secondary_bootloader]

Accessing the Bootstrap CLI

The Bootstrap CLI contains commands to support the selection of which bootloader to use.
To access the Bootstrap CLI, follow these steps:
1 Attach a serial cable to the serial console port of the switch.
2 Attach the other end of the serial cable to a properly configured terminal or terminal emulator.
3 Power cycle or reboot the switch.
4 As soon as you see the Bootstrap Banner, press the spacebar.
The BOOTSTRAP prompt will appear on the screen.

Table 64 lists the Bootstrap commands.
