- Moxa EDS-405A-MM-SC — 5-port managed switch with fiber, widely used in SCADA networks
- Hirschmann RS20-0400M2M2SDAEHH — Industrial managed switch, DIN rail, comparable port density
- Cisco IE-2000-4T-B — Cisco industrial managed switch, suitable for high-security environments
- Phoenix Contact FL SWITCH 2005 — 5-port unmanaged alternative for cost-sensitive applications
- Westermo RED-100-LV — Rugged managed switch for substation and utility automation
Note: Konmask.com recommends using the original GE 336A4940DNP517FX for mission-critical systems to ensure full protocol and firmware compatibility.
Why Choose the Original Model
- DNP3 Protocol Native Support: Purpose-built for utility and substation automation networks requiring DNP3 over Ethernet
- Fiber Uplink (FX): The “FX” suffix denotes a fiber SFP uplink port, enabling long-distance, noise-immune backbone connections
- Proven Reliability: Validated in GE Mark VI, Mark VIe, and EX2100 control system architectures
- Firmware Ecosystem: Seamless integration with GE Toolbox and ControlST software suites
- Extended Temperature Range: Rated for harsh industrial environments without additional enclosure cooling
Typical Applications
- Power generation plant control networks (gas turbine, steam turbine, combined cycle)
- Substation automation and protection relay communication (IEC 61850 / DNP3)
- Oil & gas SCADA field network infrastructure
- Water treatment and utility distribution control systems
- Industrial process automation backbones requiring fiber ring topology
System Compatibility
- GE Mark VI / Mark VIe Turbine Control Systems
- GE EX2100 / EX2100e Excitation Control
- GE Multilin Protection Relays (via DNP3/Modbus TCP)
- GE iFIX / Proficy HMI/SCADA
- Third-party DCS/PLC platforms supporting standard Ethernet protocols (Modbus TCP, EtherNet/IP)
Selection Guide
Use the following criteria to determine if the GE 336A4940DNP517FX is the right switch for your application:
- Need fiber uplink? → Yes: 336A4940DNP517FX | No: 336A4940DNP517 (copper only)
- Require DNP3 protocol? → Confirm DNP3 support is needed; this model is optimized for DNP3 environments
- Port count sufficient? → 5 ports (4 copper + 1 fiber); for larger networks consider GE’s 8- or 16-port variants
- Operating environment? → -40°C to +85°C rated; suitable for outdoor cabinets and harsh plant floors
- Budget vs. OEM? → For non-critical auxiliary networks, Moxa EDS-405A or Phoenix Contact FL SWITCH 2005 offer cost savings; for primary control networks, use OEM

Replacement & Compatibility FAQ
Q: Can I replace the 336A4940DNP517FX with a standard commercial Ethernet switch?
A: Not recommended for primary control networks. Industrial switches offer extended temperature ratings, DIN rail mounting, and protocol-specific features absent in commercial units.
Q: What does “FX” mean in the part number?
A: “FX” denotes a fiber optic (Fast Ethernet, multimode or singlemode) SFP uplink port, as opposed to copper RJ45.
Q: Is the Moxa EDS-405A a drop-in replacement?
A: Electrically compatible in most cases, but firmware and management interface differ. Validate with your system integrator before substitution in GE Mark VI environments.
Q: Do you offer warranty on sourced units?
A: Yes — 90-day functional warranty on all units. Extended warranty available upon request.
Q: Can this switch be used with non-GE PLCs?
A: Yes. Standard Modbus TCP and EtherNet/IP support allows integration with Siemens, Rockwell, Schneider, and other third-party automation platforms.
