Backing Up and Restoring XT Series Certificates
About this task
This section explains how to backup and restore certificates using a USB key to store the
certificate information. You can only perform this procedure from the endpoint's interface. If you
want to delete the certificates without first backing them up, proceed as explained in
Deleting XT
Series Certificates on page 247.
Note:
Once you upload the signed certificate and the CA, you can then export your certificate and
keys in PKCS#12 file format.
Procedure
1. Connect a USB key to the USB port of the XT Codec Unit (Figure 124: Connecting a USB
Key to the XT Codec Unit on page 246).

2. To back up a certificate to the USB key, select Advanced > Utilities > Certificates >
Backup.
The system copies the certificates and associated keys to the root folder of your USB key.
3. If you select Backup and Remove, the system first copies the certificates and associated
keys to the USB key and then removes them from the XT Codec Unit.
4. To restore a certificate into the system, select Advanced > Utilities > Certificates >
Restore. This automatically restores the certificates and associated keys to the system.
5. To remove a certificate from the system, select Advanced > Utilities > Certificates >
Delete Certificate. When you remove a certificate, the system returns to using the default
certificate.
