   • The HTTPS Port field specifies the port for Server Administrator. The default secure port for Server Administrator is 1311.
     NOTE: Changing the port number to an invalid or in-use port number may prevent other applications or browsers from accessing Server Administrator on the managed system. For a list of default ports, see the Server Administrator Installation Guide available at dell.com/openmanagemanuals.
   • The IP Address to Bind to field specifies the IP addresses for the managed system that Server Administrator binds to when starting a session. Select All to bind to all IP addresses applicable for your system. Select Specific to bind to a specific IP address.
     NOTE: Changing the IP Address to Bind to value to a value other than All may prevent other applications or browsers from accessing Server Administrator on the managed system.
   • The Mail To field specifies the email addresses to which you want to send emails about updates by default. You can configure multiple email addresses and use a comma to separate each one.
   • The SMTP Server Name (or IP Address) and DNS Suffix for SMTP Server fields specify your company or organization's Simple Mail Transfer Protocol (SMTP) and domain name server (DNS) suffix. To enable Server Administrator to send emails, type the IP address and DNS suffix for the SMTP Server for your company or organization in the appropriate fields.
     NOTE: For security reasons, your company or organization might not allow emails to be sent through the SMTP server to outside accounts.

   • The SSL Cipher field specifies a secure connection between the web server and the browser. Choose the ciphers that support the web server while configuring. The connection service does not start if an invalid cipher suite is set. By default, the following are the cipher suite values:

     TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,

     TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,

     TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,

     TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,

     TLS_RSA_WITH_AES_128_CBC_SHA256,

     TLS_RSA_WITH_AES_128_CBC_SHA,

     TLS_RSA_WITH_AES_256_CBC_SHA256,

     TLS_RSA_WITH_AES_256_CBC_SHANOTE

     NOTE: If an incorrect cipher value is set and the connection service fails to start, use the CLI command prompt or manually set the valid ciphers and restart the connection service.
   • The SSL Protocols field allows you to set from the web server listed SSL protocols to establish an HTTPS connection. The possible values are: TLSv1 , TLSv1.1 , TLSv1.2 , (TLSv1, TLSv1.1) , (TLSv1.1, TLSv1.2) and (TLSv1, TLSv1.1, TLSv1.2). By default, the value of SSL protocol is set to (TLSv1, TLSv1.1, TLSv1.2). The changes take effect after web server restart.
     NOTE: If the protocol is not supported by default configurations, enable the SSL Protocol from the browser settings.
   • Key Signing Algorithm (For Self-Signed Certificate) — Allows you to select a supported signing algorithm. If you select either SHA 512 or SHA 256, ensure that your operating system/browser supports this algorithm. If you select one of these options without the requisite operating system/browser support, Server Administrator displays a cannot display the webpage error. This field is meant only for Server Administrator autogenerated self-signed certificates. The drop-down list is grayed out if you import or generate new certificates into Server Administrator.

   • The Java Runtime Environment — Allows you to select the one of the following options:

     • Bundled JRE — Enables use of the JRE provided along with the System Administrator.

     • System JRE — Enables use of the JRE installed on the system. Select the required version from the drop-down list.

     NOTE: Server Administrator does not recommend the upgrade to major versions of Java Runtime Environment (JRE), it is limited to the security patch and minor JRE versions. For more details, see the release notes of Server Administrator (packaged with Server Administrator application) or at dell.com/openmanagemanuals.
     NOTE: If the JRE does not exist on the system on which Server Administrator is running, the JRE provided with the Server Administrator is used.
