1. Restoring Factory Defaults

Stacking Dell Force10 MXL 10/40G Switches

Another way to completely wipe out all configurations and return to factory defaults is to erase the

meta-data (NVRAM) and delete the startup configuration by following the instructions in Restoring

factory defaults below.

Restoring factory defaults

Usually a standalone MXL can be set to factory defaults simply by deleting the startup configuration

and reloading the switch (Step 2). However, once an MXL has been stacked, additional steps are

required in order to remove the stacking configuration from the NVRAM meta-data. To completely

remove all configurations (including stacking) and return to factory defaults on any stack member:

1. Unplug the stacking cables connecting the switch to the rest of the stack.

2. From the console prompt of the removed switch, type delete startup-configuration and press

enter, then reload the system. If prompted to save the configuration, enter "no".

3. During reboot, press any key at the second prompt to get to the BOOT_USER # menu (the

bootup process allows 5 seconds to press any key to get to this menu).

4. From the BOOT_USER # prompt, type enable admin to get into administrative mode. The

default password is "ncorerulz", which brings up the BOOT_ADMIN # prompt.

5. Type nvram erase <enter>. Then type reload <enter>. When the reload completes, the switch

will be at factory defaults.

Constant stack configuration

A minimum stack configuration is always present on a stack-capable switch. Even if a switch has never

been stacked with other switches, it is still considered a "stack of 1", and therefore will always contain

"stack-unit" lines in the running configuration. Here is an example configuration of a device that is not

stacked.

Note: FTOS starts numbering stack units at zero, so a single stack-unit 0 as shown below is in fact a

stack unit of 1.
