Rebooting
You can use boot commands to immediately initiate software boots from a software image stored
in primary or secondary flash on a Dell PowerConnect device or from a BootP or TFTP server. You
can test new versions of code on a Dell PowerConnect device or choose the preferred boot source
from the console boot prompt without requiring a system reset.
NOTE
It is very important that you verify a successful TFTP transfer of the boot code before you reset the
system. If the boot code is not transferred successfully but you try to reset the system, the system
will not have the boot code with which to successfully boot.
By default, the Dell device first attempts to boot from the image stored in its primary flash, then its
secondary flash, and then from a TFTP server. You can modify this booting sequence at the global
CONFIG level of the CLI using the boot system… command.
To initiate an immediate boot from the CLI, enter one of the boot system… commands.
Configuration notes
If you are booting the device from a TFTP server through a fiber connection, use the following
command: boot system tftp <ip-address> <filename> fiber-port.
In an IronStack, the boot system tftp <ip-address> <filename> command will cause the
system to boot the active unit with the image specified in the command. The rest of the units in
the stack will boot with the primary or secondary image, depending on their boot configuration.
Displaying the boot preference
Use the show boot-preference command to display the boot sequence in the startup config and
running config files. The boot sequence displayed is also identified as either user-configured or the
default.
The following example shows the default boot sequence preference.
PowerConnect #show boot-preference
Boot system preference (Configured):

Boot system preference(Default):
