Cisco IE-3000-8TC-E Industrial Ethernet Switch – 8x 10/100 downlinks with coated PCB for harsh environments

The Cisco IE-3000-8TC-E is a compact, managed industrial Ethernet switch built for rugged control cabinets and plant floors. One thing I appreciate is how it balances reliability with familiar Cisco IOS features—so operations teams get industrial-grade hardware without giving up enterprise-class management. The “-E” suffix indicates conformal coating on the PCB, which typically helps in dusty, humid, or corrosive atmospheres often found around pumps, conveyors, and packaging lines.

Key Features

• 8x 10/100BASE‑TX downlink ports – Reliable Fast Ethernet for PLCs, HMIs, drives, and remote I/O without overpaying for unused Gigabit.
• 2 dual‑purpose uplinks – Use either RJ‑45 (10/100/1000) or SFP modules for fiber runs; you can adapt per panel or distance needs.
• Conformal‑coated “-E” build – Extra protection against moisture and airborne contaminants; in many cases this extends service life on the line.
• Fanless, DIN‑rail design – Quiet operation and fewer moving parts; ideal for sealed or low‑maintenance cabinets.
• Cisco IOS managed – VLANs, QoS, RSTP/MSTP, IGMP Snooping, port security, and Cisco REP for fast ring recovery.
• Dual DC power inputs – Redundant supplies improve uptime during maintenance or unexpected drops on one feed.
• Industrial temperature range – From my experience, this model handles extreme ambient swings often seen during seasonal shifts.
• Flexible fiber options – Add SFPs when you need long runs or EMI immunity between cabinets or buildings.

Technical Specifications

Related and Supporting Products

• IE-3000-8TC – Same port layout without the conformal coating; good for cleaner, controlled cabinets.
• IE-3300 Series (e.g., IE-3300-8P2S-E) – Newer platform with Gigabit downlinks and PoE/PoE+ options; preferred where bandwidth or power to endpoints is needed.
• PWR-IE65W-AC-DC / PWR-IE170W-AC-DC – Industrial AC/DC power supplies commonly paired with Cisco IE switches.
• GLC-FE-100FX / GLC-SX-MMD / GLC-LH-SMD – SFP modules to extend uplinks over multimode or single‑mode fiber.
• DIN-rail mounting kits & grounding accessories – For clean panel integration and bonding to cabinet ground.

You might notice that in plants with long cable runs or high EMI, moving the uplinks to fiber SFPs reduces nuisance retries and helps SCADA polling stay consistent.

Installation & Maintenance

• Cabinet & mounting – Install on DIN‑rail or panel; allow side/top clearance for airflow. A sealed IP-rated cabinet is recommended for dusty or humid areas.
• Power wiring – Land dual 12–48 VDC feeds on the terminal block and bond the chassis ground to the cabinet earth. From my experience, separate power and data harnesses to minimize noise.
• Networking – Use industrial‑grade shielded patch cords; keep copper runs within spec and use SFP fiber for distances or high‑EMI zones.
• Safety – De‑energize before servicing. Verify the panel’s short‑circuit protection and correct fuse/CB sizing upstream.
• Routine maintenance – Inspect terminal blocks for looseness, clean dust with dry air, check event logs. Plan periodic Cisco IOS updates and back up the running configuration after changes.
• Commissioning tip – Enable REP or RSTP on ring topologies and validate failover times with a quick link‑pull test; it saves troubleshooting later.

Quality & Certifications

• Certifications – CE, UL/cUL, RoHS; commonly used in areas requiring Class I, Division 2 / ATEX Zone 2 suitability for non‑incendive locations (verify specific release docs for your site).
• Manufacturer policy – Cisco hardware warranty and Smart Net Total Care service options are available; terms may vary by region and contract.
