IFS Line / Network Transmission

24-port Gigabit
Layer 2 Industrial
Managed Switch

Overview

The IFS 24-port Gigabit Managed Industrial Switch is an
environmentally hardened Layer 2 switch with high port density
and Gigabit Fiber uplink capability in a rugged IP30 rated 19" rack­mountable design. This Industrial Switch provides full management
capabilities and is perfect for applications such as factory automation,
distribution centers, utilities and intelligent transportation systems (ITS).

Environmentally Hardened Design for Industrial Networking

This switch is engineered for stable operation in electrically harsh
and demanding environments under a wide operating temperature
range. This switch is equipped with advanced management features
and provides 24 10/100/1000Base-T copper ports and 4 shared
1000Base-SX/LX SFP slots. It is designed with a non-blocking switch
fabric and is capable of providing wire-speed throughput as high as
48Gbps for reliable operation from -40 to 75°C without any packet
loss and CRC errors.

Robust Layer 2 Features

This Industrial Managed Switch provides advanced Layer 2 to
Layer 4 data switching and redundancy, such as support for STP,
RSTP and MSTP to greatly improve redundant data backup and
guarantee network resilience. Other features include Quality of
Service traffic control, network access control and authentication,
and Secure Management features to protect a facilities industrial
network connectivity with a reliable switching recovery capability that
is suitable for implementing highly fault-tolerant and mesh network
architectures. This switch also supports standard Simple Network
Management Protocol (SNMP) and includes an advance SNMP
feature set to monitor the status of the switch and traffic per port.
The switch can also be monitored via any standards-based SNMP
management software.

IPv6 Support

The IFS Industrial Managed Switch is the ideal solution for new or
existing networks that are adopting IPv6. This switch supports both
IPv4 and IPv6 management functions and can work with an original
IPv4 network infrastructure. With an easy-to-use management
interface and a robust number of management functions, the IFS
Industrial Managed Switch is the best choice for building out IPv6
FTTx edge services and for Industrial applications to connect with an
IPv6 network.

Powerful Security

This switch offers comprehensive Access Control List (ACL)
for enforcing security to the edge. Its protection mechanisms
also comprise of port-based 802.1x, RADIUS and TACACS+
users access authentication, and MAC-based user and device
authentication allowing network administrators to managed highly
secured industrial networks.

Integrated Intrusion/Event Alarms via Digital I/O

The IFS Industrial Managed Switch provides digital input and output
functions to assist system administrator’s to efficiently react to
emergency events. The digital input can be setup to indicate alarm
events and send a message or alarm to the network system once
the urgent event is detected by an external device, such as a door or
window contact. The digital output function can define the immediate
response such as a port failed or power failed related to the alarm event.

Redundant Power to Ensure Continuous Operation

The IFS Industrial Managed Switch also supports redundant
DC power inputs with transient protection to ensure reliable and
continuous operation. The redundant power system is designed to
operate in a range from 36~72VDC for reliable operation in mission
critical network deployments which require a highly resilient network.
