Secure server certificates ensure the identity of a remote system andensure that information exchanged with the remote system cannot be viewed or changed byothers. To ensure this security for your DRAC 4, it is strongly recommended that you generate aCSR, submit the CSR to a CA.After the CA approves the CSR and sends you a certificate, you must upload the certificate tothe DRAC 4 firmware. The CSR information stored on the DRAC 4 firmware must match theinformation contained in the certificate.
