Directions for installing SANS certificates via the CLI

Below are directions for installing the SANS (Subject Alternative Name) certificate using the CLI:

  • The first step is accessing your unit via the CLI interface.
  • Issue the unit a /N and select option Web Access

  • At the WEB ACCESS screen you will need to fill out the SSL Certificate options. (5 thru 11)

  • * Option 5 (common name) must already exist in DNS server

    Select Option 12. SAN Options


    On this screen you can select a slot to enter Alternative names or IP addresses that you wish to have in the certificate we will make. On the above screen if I want to edit Slot 1, I will get the following screen.

    Select SAN type (IP address or DNS name) and Value

    Hit <esc> twice to get to the main WEB ACCESS Screen

    • Select option CSR Command and then select 1. Generate CSR.
      • It will prompt you to create a password, define password and hit enter

    • Next select the option to Display CSR key
      • It will prompt you to configure your terminal application to receive the file.
        • Make sure the file is captured as a binary file
          • For example in Tera term you check the binary box
            • Note that it takes approximately 2 ½ minutes to create cert

    • Submit the CERTIFICATE to a website that will create a signed certificate for you.
      • Note that Verisign may take a couple of days to process your request.
    • After having received the certificate select the option CRT Commands
      • Select Upload Signed CRT Certificate (navigate to where you have the signed Certificate)
      • Upload the server key in binary format
        • When using Tera Term, go to file=>send file (check binary), select open

    * Note that because the file is small there will be no indicator that it has finished transferring. Import should be almost instantaneous.  ESC to exit the upload menu.

    • Next verify that the server key took by selecting Display Signed CRT Certificate and selecting enter to make sure it took.

    • Next you will need to toggle the web servers off and on.

    ESC to save changes

    • Issue a “/n” and select the option for web. Now set both HTTP & HTTPS to on.
    • Next verify that the certificate took by opening up an HTTPS web session to the device.
    • Directions may differ here due to browser and updates. The example below is for Chrome using the following build: Version 65.0.3325.181 (Official Build) (64-bit). At the top left of the URL select the Icon and click on the link below certificate.

    Verify that the “Issued by” is correct for the certificate.
