Product Overview

TL;DR: The IE-3505H-16T is the advanced model in the IE3500 Heavy Duty Series, adding HSR (High-Availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol) lossless redundancy to the 16 GE M12 port platform. It provides zero-packet-loss failover for mission-critical industrial environments like substations, railways, and process automation.

HSR/PRP Lossless Redundancy

High-Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) ensure zero-packet-loss failover for uninterrupted connectivity.

IP66/IP67 Heavy Duty

Dustproof and waterproof design rated for extreme temperatures (-40°C to +75°C), shock, vibration, and corrosive environments.

OT Security Built-In

Cisco Cyber Vision identifies assets and vulnerabilities. TrustSec microsegmentation and Secure Equipment Access provide zero-trust protection.

ThousandEyes Agent

Host ThousandEyes Enterprise Agent for device-to-cloud network assurance and faster issue resolution across IT and OT networks.

Fabric Support

Extend IT fabric into OT with SD-Access Fabric Edge and BGP-EVPN support for scalable, easy-to-manage large networks.

TSN Frame-Preemption

IEEE 802.1Qbu/802.3br frame-preemption reduces jitter and delay for time-sensitive control traffic in OT networks.

Frequently Asked Questions

What is HSR/PRP?

HSR (High-Availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol) are IEC 62439-3 standards that provide zero-packet-loss failover by sending duplicate frames over redundant paths. The IE-3505H also supports HSR-PRP Dual Redbox and PTP over HSR/PRP.

How does the 3505H differ from the 3500H-16T?

The IE-3505H-16T adds HSR, PRP, HSR-SAN, HSR-PRP Dual Redbox, PTP over HSR, and PTP over PRP protocols that the IE-3500H-16T does not support. These are critical for substation, railway, and process automation deployments.

Does this model support PoE?

No. The IE-3505H-16T is a data-only model with lossless redundancy. For PoE, consider the IE-3500H-14P2T or IE-3500H-12P2MU2X.

What is the MTBF?

The IE-3505H-16T has a mean time between failures of 404,209 hours.
