  4. Step 2 of the New Connection wizard requires no mandatory input. Click
    Next
    .
    When you click through this screen without configuring properties, the values are populated from the cluster configuration.
  5. In Step 3 of the New Connection wizard, configure the Blaze Staging Directory property with the path that you configured on the cluster in "Create Blaze Engine Directories and Grant Permissions."
  6. Configure the Blaze User Name property with the same user name that you used to configure the Impersonation User in Step 1 of this topic.
  7. Configure the Minimum Port and Maximum Port properties with a port range for the connection.
    You can supply a range within the port range of an existing Grid Manager, as long as ports are available when the mapping runs. The default range is 300 ports.
