What you should know

Depending on your integration, one of the following cipher suites must be added to allow the units to communicate with the appliance:
Mercury LP controller integration on firmware 1.31 and earlier
  • TLS_RSA_WITH_AES_256_GCM_SHA384
  • TLS_RSA_WITH_AES_128_GCM_SHA256
Mercury EP controller integration on firmware 1.29.7 and earlier
  • TLS_RSA_WITH_AES_256_CBC_SHA

Procedure

  1. In Windows, run gpedit.msc to open the Local Group Policy Editor.
  2. Navigate to Computer Configuration > Administrative Templates > Network > SSL Configuration Settings.
  3. Double-click SSL Cipher Suite Order.
  4. In the Options pane, in the SSL Cipher Suites field, add a comma to the end of the list followed by the cipher suite applicable to your integration. Don't add any spaces.
