Powered internally via the rack backplane at 555 mA from the 3.3 V DC supply — no separate power wiring needed. The four RJ45 ports support 10/100 Mbit/s with auto-crossover, and the switch stack includes RSTP for redundant ring topologies, port mirroring for diagnostics, and bandwidth management. ## Compared to BMXNOE0100 — not a drop-in The BMXNOE0100 is a single-port Ethernet module for the same M340 rack, but it draws 90 mA from a separate 24 V DC supply, not from the backplane. The BMXNOC0401 replaces that external supply need and adds three extra ports plus managed switch features (RSTP, port mirroring). The NOE0100 has a RESET push-button for cold restart; the NOC0401 only reports an ERR LED. If your panel was wired for the NOE0100's 24 V supply, you cannot simply swap without removing that supply and verifying the backplane power budget can handle the extra 555 mA at 3.3 V. Also confirm the application needs layer-2 switching — the NOC0401 is a switch, not just a gateway. ## Rack fitting & integration Standard format module — occupies one slot in the M340 rack. No external power connection; power comes from the rack's backplane. LEDs indicate RUN (green), ERR (red), ETH STS (amber), MS (green/red), and NS (green/red). Communication services include Modbus TCP I/O Scanner and Messaging, EtherNet/IP I/O Scanner and Messaging, FDR server, SNMP, and web server (Data Editor, Rack Viewer). Supports Bandwidth Management and is rated Transparent Ready Class B30. IP20 protection — install in a cabinet.","metaTitle":"BMXNOC0401 Modicon M340 Ethernet Module, 4-port Switch","metaDescription":"Schneider Modicon M340 Ethernet TCP/IP module with embedded 4-port switch, Transparent Ready Class B30.
