Moxa IM-6700A-8TX – 8-port Fast Ethernet RJ45 module for IKS-67xxA industrial managed switches

The Moxa IM-6700A-8TX is an 8-port 10/100BaseT(X) copper interface module designed for the IKS-67xxA modular managed switch platform (such as IKS-6726A and IKS-6728A). If you’re expanding field devices or segmenting control networks, this card adds eight auto-negotiating RJ45 ports in a single front-insert module. From my experience, it’s the straightforward way to scale Fast Ethernet on existing Moxa rackmount chassis without touching your fiber backbone or control-room layout.

Typical use cases include adding I/O drops for PLC cells, connecting HMIs and drives on production lines, or building redundancy rings at the edge where Fast Ethernet still dominates. One thing I appreciate is how it simply adopts the switch’s existing software feature set—zero surprises on VLANs, QoS, or security, because all of that lives in the host chassis.

Key Features

• 8 x 10/100BaseT(X) RJ45 ports – Fast Ethernet expansion in one slot; ideal for brownfield networks that do not require Gigabit on every edge device.
• Auto-negotiation & auto MDI/MDI-X – Simplifies field cabling; typically no need for crossover cables, even on legacy devices.
• IEEE 802.3/802.3u/802.3x compliance – Standard link and flow control behavior, so it plays nicely with mixed-vendor environments.
• Hot-insertion friendly design – Front-insert with captive screws; in many cases it can be swapped with minimal disruption when the chassis supports module replacement.
• Integrated port LEDs – Quick visual checks for link/activity and speed reduce troubleshooting time on the floor.
• Industrial build – Matches the IKS-67xxA mechanical form factor; designed for cabinet installation with vibration-resistant retention.

Related or Supporting Products

• IKS-6726A – Modular managed Ethernet switch (compact rackmount). Pairs with IM-6700A-8TX for dense Fast Ethernet edge expansion.
• IKS-6728A – Larger slot count than IKS-6726A, suitable when you anticipate multiple interface modules per chassis.
• IM-6700A-4SFP – Fiber SFP interface module (Fast Ethernet). Choose this when longer distances or EMI immunity are priority.
• IM-6700A-8TX-T – Wide-temperature variant of the 8-port copper module for harsher environments.

A maintenance lead at a food & beverage plant told us the swap from a mixed copper/fiber setup to dual IM-6700A-8TX cards “felt like adding a small edge switch inside the chassis”—cabling got cleaner, and they kept the same IKS configuration templates.

Installation & Maintenance

• Cabinet and airflow – Install the host chassis in a 19-inch cabinet with adequate ventilation. Keep front and rear clearances for cable bend radius and module insertion.
• Wiring – Use industrial-grade Cat5e or better for 100 Mbps links. Keep runs within 100 meters; shielded cable is recommended in areas with heavy EMI.
• Module handling – Wear an ESD strap; insert the module straight and tighten the captive screws evenly. If hot-swap is not confirmed for your chassis/firmware, schedule a brief maintenance window and power down.
• Safety – De-energize connected field devices when feasible. Label port assignments to avoid loop creation during commissioning.
• Routine maintenance – Periodically check port LED status, clean dust from the faceplate, and review the host switch firmware release notes for stability/security updates.
• Spare strategy – In many cases, keeping one spare IM-6700A-8TX per site shortens MTTR for large production lines.
