Using an SD Card
SD Card Operation

write command—Saves the running configuration. If the system boots from an SD card and you run a write
command, the system saves the running configuration to the SD card, if the card is still installed. If the SD card has
been removed, the system saves the running configuration to the internal flash memory and displays this message:
WARNING: The SD flash is not present.
The running-config is saved to the on-board flash.
NOTE: This warning message is displayed only once.
If the system boots from the internal flash memory and you then insert an SD card and run the write command, the
system saves the running configuration to the internal flash memory.

boot command—Lets you change the system boot parameters.
If the system boots from an SD card and you run a boot command, the following behavior applies:
— If the SD card is installed and the system boot path or configuration file path points to the SD card, the system
boot path or configuration file path is saved to the SD card
— If the SD card is installed and the system boot path or configuration file path points to the internal flash memory,
the system boot path or configuration file path is saved to the internal flash memory
— If the SD card has been removed and the system boot path or configuration file path points to the SD card, the
system boot path or configuration file path is not saved and the following message displays:
WARNING: The BOOT/config file path points to the
SD flash card and the SD flash card is not present.
The environment variable(s) is not saved.
NOTE: This warning message is displayed only once.
If the system boots from the internal flash memory and you then insert an SD card and run the boot command, the
following behavior applies:
— If the system boot path or configuration file path points to the internal flash memory, the system boot path or
configuration file path is saved to the internal flash memory
— If the system boot path or configuration file path points to the SD card, the system boot path or configuration
file path is saved to the SD card and the following message is displayed:
WARNING: The BOOT/config file path points to the
SD flash card. The environment variable(s) is
saved onto the SD flash card.
NOTE: This warning message is displayed only once.
— If the SD card has been removed and the system boot path or configuration file path points to the SD card, the
system boot path or configuration file path is not saved and the following message is displayed:
WARNING: The BOOT/config file path points to the
SD flash card and the SD flash card is not present.
The environment variable(s) is not saved.
NOTE: This warning message is displayed only once.

sync command—Copies the IOS image directory (which includes the IOS image file, FPGA image files, Device
Manager files, and Profinet/CIP configuration files), the config.text IOS configuration file, the vlan.dat VLAN
configuration file, and IOS boot parameters from the internal flash memory to the SD card or from the SD card to the
internal flash memory. This command verifies that the IOS image is appropriate for the switch model and that enough
destination flash memory is present, and aborts the sync process if a potential problem is detected. The sync
command obtains the source IOS image directory path and source IOS configuration files path from the IOS boot
