11 Supported Ports in a DR Series System Table 1 lists the application and service ports found on a normally operating DR Series system. There may be other ports that are not listed here, that an administrator may need to open and enable to support specific operations across the network. Be aware that the ports listed in Table 1 may not reflect your specific network environment, or any planned deployment. While some of these DR Series system ports may not need to be accessible through the firewall, this information is made available when deploying the DR Series system in your own network because it indicates supported ports that may need to be exposed.

deployment. While some of these DR Series system ports may not need to be accessible through the firewall, this
information is made available when deploying the DR Series system in your own network because it indicates supported
