Restoring Factory-Default Settings

When you restore factory-default settings on a switch, the existing NVRAM settings, startup configuration, and all configured

settings are deleted.

To restore the factory-default settings, enter the restore factory-defaults {clear-all | nvram} command in

EXEC Privilege mode.

CAUTION: There is no undo for this command.

Important Points to Remember

● When you restore the factory-default settings on all units in a stack, the units are placed in standalone mode.

● After the restore is complete, a switch reloads immediately.

The following example shows how the restore factory-defaults command restores a switch to its factory default settings.

Dell# restore factory-defaults nvram

Restoring Factory-Default Boot Environment Variables

The Boot line determines the location of the image that is used to boot up the switch after restoring factory-default settings.

Ideally, these locations contain valid images, which the switch uses to boot up.

When you restore factory-default settings, you can either use a flash boot procedure or a network boot procedure to boot the

switch.

When you use a flash boot procedure to boot the switch, the reset boot variables are displayed below restore bootvar in

the command output.
