24 100FX SFP + 4 GE Combo SFP Managed Switch
-40 to 75C, IEC61850
Overview
LevelOne IES-2891 Industry Ethernet Switch provides 24 100Base-FX SFP
slots plus 4 port Gigabit Combo SFP to enable high speed network at
mission-critical environment. With the 1U height rack-mountable size,
this switch can be easily installed in the cabinet, plus the clearly visible
status LEDs provide simple monitoring of port link activity. Moreover,
the SFP slots support pluggable modules that enabling you to choose
from a variety of transceivers.
Management
It supports a variety of management features including: CLI via Console
or Telnet; Graphic User Interface via Web Browser or Simple Network
Management Protocol via SNMP tools. It provides better visibility and
management of those critical assets.
High Reliability
All components are built to withstand harsh environment applications
without compromise where humidity, temperature variation and even
shock vibration are concerns, including Electric & Utility, Critical
Infrastructure, Transportation and Surveillance Security. This device
operates under -40 to 75 Celsius (-40 to 167 Fahrenheit) temperature.
GOOSE Message
Critical GOOSE (Generic Object Oriented Substation Event) messages
can be sent reliably using the multicast and prioritisation functionality
within LevelOne Industrial switches. Moreover, the test was conducted
by KEMA, a renown laboratory for testing and certication for
substations.
Resilient Ring Network
Supports Ring topology network providing simple installation and ultra
fast network recovery performance, less than 15ms. Unlike much
complex resilient topology, such as a redundant star, the Ring simplies
the network design and requires less cabling installation. In addition,
fast network recovery time helps minimize system downtime.
Substation & Railway Applications
This device is complied with IEC 61850-3 / IEEE 1613 for the power
substations and EN 50121-4 for the railway applications. IEC 61850-3 is
an international standard for electrical substation systems. The standard
enables integration of all control, measurement, monitoring and
protection functions within a substation.
