The Cisco IE3500 Heavy Duty Series (IE3500H) switches deliver high bandwidth, high power and better switching performance in a dustproof and waterproof form factor. The Cisco IE3500 Heavy Duty Series is designed to support features that enable the industrial network infrastructure to seamlessly accommodate machine vision use cases, AI-driven analysis, virtualization, and robust security for Operational Technology (OT) networks.

Advanced Features for Operational Technology (OT) Networks

• TSN Frame-Preemption: With IEEE802.1Qbu and IEEE802.3br based frame-preemption technology, the IE3500H significantly reduces jitter and delay in transmission of time-sensitive control traffic in OT networks.
• Enhanced Resiliency:The IE3500H supports protocols such as Media Redundancy Protocol (MRP), Resilient Ethernet Protocol (REP), and Device Level Ring (DLR), providing redundancy and fast failover times.
• Lossless Redundancy:For deployments requiring uninterrupted connectivity, the IE3505H includes High-Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP), ensuring seamless failover and network continuity.

Network Security and Observability

• Secure Boot: The IE3500H features Secure Boot designed to ensure that only trusted and authenticated software is executed during the boot process, with its hardware-anchored root of trust in Cisco Trust Anchor Module.
• Cyber visibility: Cisco Cyber Vision built-into the IE3500H identifies connected assets, their profiles, vulnerabilities, and communication patterns to assess your OT security posture and help drive cybersecurity best practices.
• Secure remote access: Cisco Secure Equipment Access built-into the IE3500H enables zero-trust remote access to connected assets.
• Segmentation: Cisco TrustSec technology enables policy-based segmentation that helps reduce attack surfaces and contains threats by automatically adapting access based on user and device identity.
• Network Assurance:IE3500 can host ThousandEyes Enterprise Agent¹that gains visibility into owned and third-party network to avoid network outages.

Flexible Management Options

The IE3500H offers multiple management choices to suit various deployment needs:

• On-Device Management: Use the WebUI or command line tool for standalone devices, providing an intuitive on-device GUI.
• On-Premises Management: Manage the IE3500H via Catalyst Center for on-premise deployments.
