Cisco TelePresence SX20 Quick Set Administrator Guide
Managing the video system’s
certificates
Certificate validation may be required when using TLS
(Transport Layer Security).
A server or client may require that your video system
presents a valid certificate to them before communication can
be set up.
The video system’s certificates are text files that verify the
authenticity of the system. These certificates may be issued
by a certificate authority (CA).
The certificate are listed as shown in the illustration to the
right
*
. They can be used for the following services: HTTPS,
SIP and IEEE 802.1X.
You can store several certificates on the system, but only one
certificate can be used for each service at a time.
If authentication fails, the connection will not be established.
Enabling and disabling certificates
Use the buttons to switch a
certificate on or off for the different
services.
You can also view a certificate,
and delete a certificate using the
corresponding buttons.
Contact your system administrator to obtain the
following file(s):
• Certificate (file format: .PEM)
• Private key, may be included in the same file as
the certificate (file format: .PEM format)

encrypted)
The certificate and the private key will be stored in
the same file on the video system.
