Cisco IE-4000-16GT4G-E

The Cisco IE-4000-16GT4G-E is a fully managed, rugged industrial Ethernet switch with an increased port count. It belongs to the same high-end series as the 8-port model but is designed for larger-scale deployments where more devices need to be connected within a single industrial enclosure.

The model name decodes as:

• IE-4000: Series

• 16GT: 16 x 10/100/1000 (Gigabit) Twisted-Pair (Copper) RJ45 Ports

• 4G: 4 x 1 Gigabit SFP (Fiber) Uplink Ports

• E: Enhanced Software Image (Advanced Layer 3 features)

Key Features & Specifications

• Total Ports: 20

• Copper Ports: 16 x 10/100/1000BaseT(X) RJ45

• Fiber Uplink Ports: 4 x 100/1000 SFP Slots (SFP modules sold separately)

• Software Image: Enhanced (Layer 3 Lite)

• Form Factor: DIN-rail mountable (physically larger than the 8-port model)

• Power Input: 24 VDC (standard) or 110/240 VAC (with a separate power supply module)

Detailed Analysis

1. Port Configuration & Use Cases

The 16+4 port configuration is a classic design for an industrial distribution or aggregation switch.

• 16x Gigabit Copper Ports: This high density allows you to connect a large number of devices in a centralized location.

  • Typical Devices: Multiple PLCs, HMIs, CNC machines, robotic controllers, industrial PCs, and high-bandwidth sensors.

  • Use Case: Ideal for a central control cabinet in a manufacturing cell, a substation gateway, or a control room where many field devices converge.

• 4x Gigabit SFP Fiber Ports: These provide robust uplink capabilities.

  • Usage: High-speed trunking to the network core, building redundant fiber rings, or long-distance connections to other switches. Having four allows for complex and highly available topologies.

2. "Fully Managed" / Enhanced Software Image

This switch shares the same powerful software capabilities as its 8-port sibling. The "E" image is critical for segmenting and securing a network of this size.

• Advanced Layer 3 Features (Layer 3 Lite):

  • Static Routing & RIP: Essential for routing traffic between the multiple VLANs you would logically create for 16+ devices (e.g., separating control VLAN, camera VLAN, sensor VLAN).

  • EIGRP Stub: Enables smooth integration into larger Cisco campus networks.

• Industrial Network Virtualization:

  • Cisco Field Network Director (FND): Centralized management becomes almost a necessity with a switch of this scale, allowing for configuration, monitoring, and troubleshooting from a single pane of glass.

• Advanced Security:

  • With more ports, security features like 802.1X (port-based access control) and Cisco TrustSec are crucial to prevent unauthorized devices from connecting.

• High Availability:

  • Cisco REP (Resilient Ethernet Protocol) and DLR (Device Level Ring) ensure network stability, which is critical when so many devices depend on this single aggregation point.

3. Industrial Ruggedness

It maintains the same rugged build quality as the entire IE-4000 series.

• Operating Temperature: -40 to 75°C (-40 to 167°F)

• Certifications: UL 61010-2-201, Class I Division 2 Hazardous Locations, ATEX Zone 2, IEC 61850-3/ IEEE 1613 (for electrical substations), EN 50121-4 (for railway).

• Robust Design: Conformal coating and robust housing for harsh environments.
