Enterasys I3H252-12TX User manual

Product Overview
The Enterasys I-Series is a 2-slot modular, industrially-hardened Ethernet switch with an IP50
dust-resistant design and Class 1 Division 2 support suitable for explosive gas and other physically
demanding environments, such as manufacturing plants, oil refineries, and utilities. Along with
its operational tolerance for extreme temperatures ranging from -40° C to 60° C, the I-Series
combines multi-layer switching capabilities with wire-rate performance to support the demanding
requirements of industrial applications. The I-Series provides 2 modular slots which can support
up to 24 10/100Base-T Ethernet ports as well as 2 1 Gbps Small Form Factor Pluggable (SFP)
Ethernet uplink ports. In order to provide a reliable, high-availability network, all I-Series models
support redundant, 24-volt external power supplies as well as Link Aggregation Groups (LAGs) for
scalable, redundant uplinks.
The DIN-mountable I-Series utilizes industrial-grade components and provides a set of event-driven
relay connectors to support external alarms. In addition, the I-Series offers a portable, non-volatile
memory card, which is capable of storing the system configuration and may be used by non-
technical personnel to quickly replicate the configuration on a replacement switch thus making it
an ideal solution for dynamic environments without requiring dedicated technical support personnel.
In conjunction with its non-blocking architecture, the I-Series provides strong support for a
variety of network-attached devices such as Programmable Logic Controllers (PLCs), shop
floor workstations, and security cameras. The I-Series’ highly customizable Layer 2/3/4 packet
classification capabilities together with its intelligent queuing mechanisms ensure that mission-
critical devices and applications receive prioritized access to network resources.
Making use of Enterasys’ policy capabilities, a network administrator can define distinct roles or
profiles that represent industry-specific operational groups or devices. Each defined role is granted
individualized access to specific network services and applications (e.g., supervisor, operator, PLC,
security camera) and these access privileges remain associated with users/devices for both wired
and wireless network access. Users and devices are authenticated via IEEE 802.1X, MAC address,
or web-based authentication, and then assigned a pre-defined operational role ensuring that each
user has access to appropriate information, thus aligning network resource utilization with business
goals and priorities.
In order to sustain a secure, feature-rich and cost-effective network well into the future, the I-Series
comes with a 5-year warranty.
