configuration file.
• Use the Backup Configuration screen (Section 78.9 on page 543) to save your configurations for later
use.

stored in the Switch’s RAM.

• Use the Firmware Upgrade screen (Section 78.15 on page 550) to upload the latest firmware.
• Use the Reboot System screen (Section 78.16 on page 552) to restart the Switch without physically
turning the power off and load a specific configuration file.
• Use the Tech-Support screen (Section 78.17 on page 553) to create reports for customer support if
there are problems with the Switch.
78.2 Certificates
The Switch can use HTTPS certificates that are verified by a third party to create secure HTTPS
connections between your computer and the Switch. This way, you may securely access the Switch
using the Web Configurator. See Section 66.5.2 on page 449 for more information about HTTPS.
Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity
and public key. Certificates provide a way to exchange public keys for use in authentication.
