Issue:

Understanding the Ethernet port options and their functions on the SAGE 4400 RTU.

Product:

SAGE 4400 RTU

Environment:

Substation automation systems using SAGE 4400 RTU for network communication and remote access.

Cause:

Users may be unclear about the number of Ethernet ports, their location, and configuration differences between standard and optional ports.

Resolution:

The SAGE 4400 RTU includes one standard Ethernet port on the front panel for primary access. Optional configurations may include a Switched Ethernet card providing three additional rear-panel ports and a WAN port for secondary network integration.

Switched Ethernet optimizes traffic flow and automatically detects cable type (straight-through or crossover).

Recommended practices: use a crossover cable for direct access and straight-through cables for network connections.

Each Ethernet port supports 10/100BASE-T auto-negotiation for speed and duplex settings. The WAN port uses a separate NIC and requires a unique IP address for integration into another network.
