Method 2.)

– The server certificate that you upload to the Management Card

enables SSL to authenticate that data are being received from

and sent to the correct Management Card. This provides an extra

level of security beyond the encryption of the user name,

password, and transmitted data.

– The browser matches the digital signature on the server certificate

that you uploaded to the Management Card with the signature on

the CA root certificate that is already in the browser’s certificate

– Setup requires the extra step of requesting a signed root

certificate from a Certificate Authority.

– An external Certificate Authority may charge a fee for providing

signed certificates.
