4. In the 'Subject Name' field, enter the DNS name, and then click Generate CSR. A
textual certificate signing request that contains the SSL device identifier is displayed.
5. Copy this text and send it to your security provider. The security provider (also known
as Certification Authority or CA) signs this request and then sends you a server
certificate for the device.
6. Save the certificate to a file (e.g., cert.txt). Ensure that the file is a plain-text file
containing the ‘BEGIN CERTIFICATE’ header, as shown in the example of a Base64-
Encoded X.509 Certificate below:
-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----
7. In the 'Certificates Files' group, click the Browse button corresponding to 'Send Server
Certificate...', navigate to the cert.txt file, and then click Send File.
8. When the loading of the certificate is complete, save the configuration (refer to ''Saving
Configuration'' on page 237) an
d restart the device; the Web interface uses the
provided certificate.
9. If the device was originally operating in HTTPS mode and you disabled it in Step 2,
then return it to HTTPS by setting the parameter 'Secured Web Connection (HTTPS)'
to 'HTTPS Only' (1) (refer to ''Configuring the General Security Settings'' on page 141).
Notes:
• The certificate replacement process can be repeated when necessary
(e.g., the new certificate expires).
• It is possible to use the IP address of the device (e.g., 10.3.3.1) instead of
a qualified DNS name in the Subject Name. This is not recommended
since the IP address is subject to changes and may not uniquely identify
the device.
• The server certificate can also be loaded via ini file using the parameter
HTTPSCertFileName.
