Overview of the IE-2000-8TC-L Switch
The Cisco IE-2000-8TC-L is a hardened, Layer 2+ industrial Ethernet switch designed for mission-critical environments like manufacturing plants, oil refineries, and transportation systems. Part of Cisco’s Industrial Ethernet (IE) 2000 series, this 8-port model combines Gigabit Ethernet copper connectivity with extended temperature tolerance (-40°C to 75°C) and compliance with industrial certifications (IEC 61850-3, IEEE 1613). Unlike commercial switches, it’s built to withstand vibrations, humidity, and electromagnetic interference common in factories or substations.
Key Technical Specifications
- Ports: 8 x 10/100/1000Base-T RJ45, 2 x 1G SFP uplinks
- Power Input: 12-48VDC or 24VAC (dual redundant)
- Switching Capacity: 20Gbps
- Safety Certifications: UL 61010-1, ATEX/IECEx Zone 2
- Software: Cisco IOS (15.2(7)E) with CLI/Web UI
The IE-2000-8TC-L supports Cisco Cyber Vision for OT security, enabling deep packet inspection to detect anomalies in operational technology (OT) protocols like Modbus TCP or PROFINET.
Core Use Cases and Deployment Scenarios
Industrial Automation
In manufacturing lines, the switch prioritizes traffic for PLCs (Programmable Logic Controllers) using Quality of Service (QoS) policies. Its millisecond-level failover via REP (Resilent Ethernet Protocol) ensures uninterrupted operation during conveyor belt disruptions.
Energy Grids and Substations
Compliant with IEC 61850-3 standards, the switch integrates with grid protection relays and SCADA systems. The -40°C operational rating prevents downtime in unheated substations during winter.
Transportation Networks
Deployed in railway signaling or traffic control systems, the IE-2000-8TC-L resists shock/vibration (up to 5Grms) and supports NTP for time-synchronized operations.
Key Advantages Over Commercial Switches
- Extended Lifespan: 10+ years of availability with 24/7 operation.
- Zero-Packet Loss: Non-blocking architecture handles bursty OT traffic.
- Secure Remote Management: SSH, SNMPv3, and RADIUS/TACACS+ integration.
Addressing Common Deployment Concerns
Q: Can it replace legacy serial devices in OT networks?
Yes. The switch supports serial-to-Ethernet converters (e.g., Cisco IE-2000-4S-L) for migrating RS-232/485 devices to IP.
Q: How does it handle power redundancy?
The dual 12-48VDC inputs allow connection to separate power sources. If one fails, the switch switches to the backup within 500ms.
Q: Is Layer 3 routing supported?
No. The IE-2000-8TC-L operates at Layer 2+, making it ideal for segmenting OT networks while relying on upstream routers for inter-VLAN traffic.
Procurement and Compatibility Notes
The IE-2000-8TC-L is often bundled with Cisco’s Industrial Network Director for centralized management. For standalone purchases, ensure compatibility with existing DIN rail or panel mounts. Genuine units with Cisco SMARTnet support are available via “IE-2000-8TC-L” at itmall.sale’s Cisco category. Avoid counterfeit models lacking IEC 61850-3 certification.
Final Insights
Having deployed dozens of IE-2000 switches in steel mills and wastewater plants, I’ve seen firsthand how the IE-2000-8TC-L bridges IT/OT divides. Its ruggedness is unmatched for harsh settings, but its lack of Layer 3 routing limits flexibility in complex topologies. For teams prioritizing reliability over advanced features, this switch is a workhorse—though pairing it with a Layer 3 industrial router (like Cisco IR1100) is wise for large-scale sites. If your environment demands survivability over bells and whistles, this is the box to trust.
