Product Introduction
The ABB NE870 3BSE080239R1 is an industrial Layer 3 router and firewall designed for ABB 800xA control networks. It separates client/server networks from control networks, isolates safety-related segments, and supports RNRP tunneling between redundant network domains.What sets it apart is its tight fit inside 800xA RNRP architectures. It provides eight 10/100 Mbps ports and three Gigabit Ethernet ports, plus 16–60 VDC power input and digital I/O for external alarm or status signaling. It is not a general-purpose office router. Use it only after confirming the firmware, RNRP configuration, and port assignment with the current ABB documentation.
Installation & Configuration Guide
Preparation (10 min)
- Confirm the order number 3BSE080239R1 matches the nameplate.
- Record firmware version, serial number, and MAC address.
- Prepare 24 VDC or 48 VDC supply with at least 20% current margin.
- Have a USB Micro-B cable ready for console access.
- Back up the existing NE870 configuration before removal.
Removal (5–10 min)
- Label all Ethernet cables and power leads.
- Disable RNRP maintenance mode if applicable.
- Remove power after confirming no active session depends on the unit.
- Slide the DIN rail clip and remove the router.
- Photograph terminal blocks and DIP/jumper positions before disconnecting.
Installation (10 min)
- Mount the NE870 on a clean, grounded DIN rail.
- Connect redundant DC power if available.
- Insert Ethernet cables according to the saved port map.
- Connect the console port for initial verification.
- Do not force connectors; the RJ-45 and USB Micro-B ports are rear-mounted and can be damaged by misalignment.
Power-On & Test (10 min)
- Apply 16–60 VDC and check status LEDs.
- Access the CLI and verify firmware version.
- Confirm IP addressing, VLANs, and routing tables.
- Test RNRP neighbor status if deployed in a redundant ring.
- Validate digital I/O alarm output before closing the cabinet.
Troubleshooting Quick Reference
| Symptom | Likely Cause | First Check |
|---|---|---|
| No power LED | Supply out of range or loose terminal | Measure 16–60 VDC at the terminal block |
| CLI not accessible | Wrong USB driver or baud setting | Verify USB Micro-B connection and console parameters |
| Port link down | Cable fault or speed mismatch | Test with known-good Cat5e/Cat6 cable |
| RNRP ring fault | Neighbor mismatch or firmware difference | Compare firmware and RNRP config with peer unit |
| Intermittent reboot | Undersized power supply | Confirm supply can sustain peak current plus 20% margin |
| Digital I/O not triggering | Wrong terminal assignment | Check 4-pin removable I/O block wiring |
Dimensions, Mounting & Wiring Notes
- Dimensions: 134 × 100 × 122 mm (W × H × D).
- Weight: Approx. 1.5 kg.
- Mounting: DIN rail via rear cast DIN clip.
- Ethernet: 8× 10/100BaseTX RJ-45, 3× 10/100/1000BaseTX RJ-45.
- Console: 1× USB Micro-B.
- Digital I/O: 4× digital I/O on a removable screw terminal.
- Power: 16–60 VDC; verify polarity and supply capacity before energizing.
- Clearance: Leave at least 25 mm above and below for airflow and cable bend radius.
FAQ
Can the NE870 replace an older 800xA router without re-engineering the ring?
Not automatically. RNRP depends on matching firmware, node configuration, and ring membership. Treat it as a like-for-like hardware replacement only after the configuration is validated.Is this unit sold as new original or refurbished?
Both conditions may be available. New Surplus means unused OEM stock. Refurbished units are tested under controlled conditions. Always request serial and firmware confirmation before purchase.What happens if the firmware version differs from the existing ring?
RNRP neighbors may reject the node, or the ring may fall back to non-redundant operation. Match the firmware to the existing ring unless ABB documentation approves an upgrade path.Does it support SFP fiber ports?
This variant, 3BSE080239R1, is listed with RJ-45 Ethernet ports only. If fiber uplinks are required, confirm the exact NE870 sub-model with the ABB datasheet.How much power supply capacity should I plan for?
Use the rated current at your operating voltage and add at least 20% margin. For dual-supply installations, each source should independently support the full load.Can I use it outside ABB 800xA systems?
It can route IP traffic, but its main value is RNRP integration with 800xA. Using it as a generic industrial router is possible, yet you may pay for unused redundancy features.I received a unit with a different label format. Is that normal?
ABB label layouts can change across production batches. The critical check is the order number 3BSE080239R1, serial number, firmware version, and port configuration. If any of those disagree, pause installation and request verification.
