Overview
The SD card can be used instead of the internal flash memory of the switch to update or restore configuration settings.
In addition, the SD card can be used to boot the switch. You can also copy IOS software and switch configuration settings
from a PC or from the switch to the SD card, and then use the SD card to copy this software and settings to other
switches.
When an SD card is formatted on the switch, the card is formatted with the Disk Operating System Filing System
(DOSFS), a platform-independent industry-standard file system that is supported on various Cisco switches and routers.
The switch does not support third-party SD cards or SD High Capacity (SDHC) cards. Attempting to operate the switch
with a non-supported card causes the following message to be displayed:
WARNING: Non-IT SD flash detected.
Use of this card during normal operation can impact and
severely degrade performance of the system.
Please use supported SD flash cards only.
If the write-protect switch on the SD card is in the lock position, the switch can read data on the card and boot from the
card, but updates and files cannot be written to the card.
Inserting and Removing an SD Card
To put an SD card in the switch, make sure that the card is oriented properly, and press it into the SD card slot on the
switch until the card is seated. To remove the card, press it to release it, then pull it out of the slot.
The SD card is hot-swappable, but it should not be removed from the switch during the boot process or while sdflash
write is in progress.
When an SD card is inserted, a syslog message similar to the following is logged:
Mar 30 01:38:51.965: %FLASH-6-DEVICE_INSERTED: Flash device inserted
When an SD card is removed, a syslog message similar to the following is logged:
Mar 30 01:39:12.467: %FLASH-1-DEVICE_REMOVED: Flash device removed
