GE 336A4940DNP516TX N‑TRON 16‑Port Industrial Switch (No Fiber)
Product Overview
GE 336A4940DNP516TX corresponds to N‑TRON 516TX hardware. It is a 16‑port copper‑only industrial Ethernet switch without fiber interfaces, designed for deployment in harsh industrial field networks. It is widely applied in GE gas turbine control systems, substations, traffic control and marine industrial network scenarios.
All ports of GE 336A4940DNP516TX are RJ45 copper ports with no fiber modules fitted. The base version supports plug‑and‑play. Versions with ‑A suffix deliver full managed switch capability and are configured via DB9 COM serial port. It can connect with HMI, PLC and safety‑related industrial equipment to guarantee stable forwarding of industrial control data.
GE 336A4940DNP516TX supports wide‑temperature operation. Redundant power supply reduces on‑site power‑off shutdown risks. The metal DIN‑rail housing withstands shock and vibration to satisfy high‑reliability network requirements for industrial infrastructure.

- Ultra‑wide temperature range ‑40℃ to 85℃, stable operation for low‑temperature outdoor cabinets in northern regions and high‑temperature smelting workshops
- ‑A version delivers full L2 managed functions. N‑View OPC connects with upper‑monitoring software to collect real‑time port traffic and alarms for fast network fault localization
- Metal reinforced housing passes shock‑vibration tests, suitable for high‑vibration conditions such as marine and rail‑transit applications
- Full‑port wire‑speed forwarding without packet loss, prioritizing real‑time control messages for industrial real‑time control services
Product Features
- All 16 RJ45 copper ports support auto‑negotiation and auto‑MDIX; common network cables can directly connect devices
- Dual‑color LED indicators display link status, speed, data activity and duplex mode per‑port; power status is clearly visible
- ‑A model supports local serial‑port configuration; switch parameters can be modified without network access
- IGMP snooping optimizes multicast traffic and mitigates broadcast storms; VLAN realizes logical network isolation; QoS guarantees low latency for ring‑management and real‑time interactive messages; port trunking uplifts upstream bandwidth; port mirroring supports network troubleshooting and packet capture
- N‑View OPC reads 41 traffic parameters per port and 6 system‑level parameters for uploading network status to HMI systems
- Complies with multiple industry certifications for compliant deployment in power‑station, marine and hazardous‑area sites
Application Fields
- Power substation automation systems complying with IEEE1613 standard
- Traffic signal control projects conforming to NEMA TS1/TS2 specifications
- Industrial networks for ship decks and cabins with ABS marine‑type approval
- Matching networking for GE control systems of gas turbines and large‑scale units
- Factory‑automation production lines and safety‑equipment networking
- Outdoor control cabinets and oil‑gas production‑site networks
- On‑board and platform control networks for rail transit
Product Comparison
GE 336A4940DNP516TX (N‑TRON 516TX) is a 16‑port 10/100Mbps copper‑only model without fiber ports, intended for high‑density copper‑cable access scenarios.
Compared with 516TX‑N: both have 16 copper ports, yet 516TX‑N only provides N‑View monitoring and lacks advanced management functions including VLAN, QoS and port trunking.
Compared with 516TX‑A: it is the full‑managed variant of GE 336A4940DNP516TX with both N‑View and complete advanced management capabilities.
Compared with 105TX: it is a compact 5‑port 10/100Mbps switch with fewer ports for small‑size node deployment.
Compared with 8018TX: 16 copper ports plus 2 SFP gigabit expansion slots for fiber extension, higher hardware cost for projects requiring long‑distance fiber cabling.

FAQ
Q: Does GE 336A4940DNP516TX come with built‑in fiber interfaces?
A: This unit has no fiber ports and is equipped entirely with RJ45 copper ports. If fiber connectivity is required, select alternative N‑TRON switch models with SFP or fiber ports.
Q: Can GE 336A4940DNP516TX work without connecting the COM serial port?
A: Yes. The base unmanaged version operates automatically upon power‑on. The COM serial port is only used for modifying advanced managed‑mode parameters on ‑A variants and is unnecessary for regular service.
Q: Do ‑A version and standard 516TX share identical hardware housing? Can managed functions be upgraded afterwards?
A: Housing and physical form are exactly the same. Firmware functions are factory‑fixed and cannot be upgraded via hardware modification. Confirm suffix requirements at the time of purchase.
Q: Two power terminals are provided; is dual‑path power supply mandatory for GE 336A4940DNP516TX?
A: No. The device runs normally with single‑path 10‑30VDC input. The second channel serves as redundant backup and takes over upon primary‑path power loss.
Q: Is purchasing the ‑A model mandatory to enable full N‑View OPC functions?
A: N‑View monitoring is supported by both ‑N and ‑A versions. Advanced management functions such as VLAN, QoS and port mirroring are only available on the ‑A variant.
Q: Can GE 336A4940DNP516TX be deployed under 95% ambient‑humidity conditions?
A: Yes, provided no condensation occurs. Condensation will cause port short‑circuit and hardware damage.
Q: How many source ports can be monitored simultaneously via port‑mirroring function?
A: Only one source‑port traffic can be copied to the mirror port at a time. Multi‑port monitoring requires time‑shared configuration switching.
Q: Does GE 336A4940DNP516TX support POE power output?
A: This model does not support POE. It cannot supply power to cameras or POE‑enabled terminals; separate external power supplies are required.
Notes
- Reserve 5.08cm front‑side clearance and 2.54cm side clearance for heat dissipation during installation; use Cat5 or higher‑grade cables for full 100Mbps throughput
- Serial‑port debug parameters for ‑A versions are fixed at 9600,n,8,1; ensure terminal settings match
- Avoid operation under condensing environmental conditions
- Ground the metal housing to improve EMC anti‑interference performance
- Distinguish order suffixes; ‑A, ‑N and base versions carry obvious functional differences
- GE 336A4940DNP516TX does not support fiber expansion; no SFP modules can be added
