l Provide usual services for the server, same as existing servers within utility network:
l UPS.
l Anti-virus.
l Server data backup (off-site).
l NTP.
Server, Firewall, and Network
The following typical ports are required to open the firewall, servers, and routers.
Port Purpose
TCP 2638 Systems to access the server Sybase database.
TCP 25 SMTP - Email server to server (unless changed).
TCP 8080 HTTP N_SIGHT and PLUS client / server connections.
TCP 20/21 FTP support to server (upgrades, maintenance) and FTP location
communication to R900 Gateway v1-v3 and server.
UDP 123 NTP - R900 Gateway to access server or Public NTP.
TCP 443 Web Services - R900 Gateway v4 communication with server.
TCP 3389 RDP - Support access to server.
Table 17 – Firewall, Server, and Router Ports
Key Points
l The server must connect to the utility SMTP mail server in order to process system-
generated emails and alarms. Default SMTP port TCP 25 is required
l The server must have a static IP address (internal/public-external) and DNS for R450 DCs,
R450 MCs, and R900 Gateways. Public-External IP/DNS is required for cellular; can also be
needed for other third-party application connectivity.
l The R900 Gateways require NTP service. The server should be configured with NTP in
Windows OS or other Utility NTP server; otherwise R900 Gateways need connection to
public NTP servers. Using this NTP source requires UDP 123 to be open.
l The Support Group requires FTP ports 20 and 21 to transfer files to and from the server.
