1189GB

Overview

The Greenlee Communications 1189GB is a ruggedized, industrial-grade Gigabit Ethernet switch designed for demanding environments. It features eight 10/100/1000BASE-T ports and two combo SFP slots supporting both fiber and copper connections. The device operates on a wide input voltage range of 24 to 60 VDC, ensuring compatibility with standard industrial power systems. It includes advanced Layer 2 management capabilities, such as VLAN tagging and QoS prioritization, to optimize network traffic. The unit is built with a metal enclosure rated IP40, providing protection against dust and solid objects, making it suitable for harsh industrial settings.

Feature Summary

• Industrial-grade durability with IP40-rated metal enclosure
• Hybrid connectivity via combo SFP slots supporting fiber or copper uplinks
• Layer 2 managed features including VLAN and QoS for traffic optimization
• Wide DC voltage input range for flexible power integration

Applications

• Factory automation networks requiring reliable high-speed data transmission
• Transportation infrastructure monitoring systems
• Outdoor telecommunications equipment enclosures
• Industrial IoT gateways connecting sensor arrays

Procurement Notes

Verify the specific firmware version and hardware revision upon order confirmation, as updates may alter minor interface behaviors. Ensure that the power supply matches the 24-60 VDC requirement strictly. Confirm that the SFP modules used are compatible with the combo port specifications. Check for any regional compliance certifications required for your specific deployment location before finalizing procurement.

Selection Notes

Select this model when Layer 2 manageability is required alongside robust physical construction. It is appropriate for scenarios where space is limited but high-density Gigabit connectivity is necessary. Consider this unit if existing infrastructure relies on DC power distribution rather than AC. Evaluate the need for combo ports to allow flexible media conversion without additional external converters.

Part Context

This switch belongs to Greenlee's industrial networking portfolio, targeting sectors like manufacturing and utilities. It complements other managed switches in the lineup by offering a balance of performance and ruggedness. The product line emphasizes ease of integration into existing SCADA and control networks. It serves as a critical node for aggregating data from field devices to higher-level control systems.

Replacement Considerations

Direct replacements should maintain similar port configurations and voltage ranges. Verify compatibility with existing SFP transceivers if upgrading from older models. Ensure that the replacement supports the same VLAN and QoS standards to avoid reconfiguration efforts. Cross-reference pinouts and mounting dimensions for seamless mechanical integration.
