not have to reconfigure the new switch. See the Replacing the SD Flash Memory Card, page 2-22 for
information.

Be aware that the SD card contains sensitive and security relevant information, including but not
limited to full device configuration information, public and private keys used for SSH and SSL (if those
protocols are enabled), device passwords and others. Access to SD cards for any Cisco CGS switch
should be limited to authorized personnel.
