2. Select the protocol to use, based on the server type that the certificate is stored on: TFTP or
HTTP.
3. For an HTTP upload, browse for the file on your local computer or network.
For a TFTP upload, enter the Server IP address, and specify the File Path and File Name.
4. From the Update Type field on the File Download page, select one of the following:
• SSL Trusted Root Certificate PEM File: SSL Trusted Root Certificate File (PEM Encoded)—An
SSL certificate that has been digitally signed by a certificate authority.
• SSL Server Certificate PEM File: SSL Server Certificate File (PEM Encoded)—An SSL
certificate that has been signed by another server.
• SSL DH Weak Encryption Parameter PEM File or SSL DH Strong Encryption Parameter PEM
File—DH certificates provide the algorithms for encrypting key exchanges and are used
independent of the certificate. The weak version uses a cipher strength of 512 bits and
the strong version uses a cypher strength of 1024 bits. Browser settings determine which
DH file parameters are requested at the start of the SSL session.
