Product description
The industrial managed switch is specially designed to build a full Gigabit backbone to
transmit reliable and high-speed data in demanding heavy industrial environments and
forward data to a remote network through fiber optic cabling. It comes with an IP30
rugged case and redundant power system. Besides support for 20 Gbps switch fabric
to handle extremely large amounts of video, voice, and important data in a secure
topology, the industrial managed switch provides user-friendly, advanced IPv6/ IPv4
management interfaces and abundant L2/L4 switching functions. It is the best
investment for expanding industrial business or upgrading its network infrastructure..
IPv6/IPv4 full-function secure switch for building automation networking
The industrial managed switch is the ideal solution to fulfilling the demand of IPv6
management gigabit Ethernet switches, especially in the industrial-hardened
environment. It supports both IPv4 and IPv6 protocols, advanced Layer 2 to Layer 4
data switching and redundancy, QoS traffic control, network access control and
authentication, and secure management features to protect customer’s industrial and
building automation network connectivity with reliable switching recovery capability that
is suitable for implementing fault tolerant and mesh network architectures.
Redundant ring, fast recovery for critical network applications
The industrial managed switch supports redundant ring technology and features strong,
rapid self-recovery capability to prevent interruptions and external intrusions. It
incorporates advanced ITU-T G.8032 ERPS (Ethernet Ring Protection Switching)
technology, Spanning Tree Protocol (802.1s MSTP), and redundant power input
system into the customer’s industrial automation network to enhance system reliability
and uptime in harsh factory environments. In a certain simple ring network, the
recovery time of data link can be as fast as 20 ms.
Environmentally hardened design
With its IP30 aluminum case, the industrial managed switch provides a high level of
immunity against electromagnetic interference and heavy electrical surges which are
usually found on plant floors or in curb-side traffic control cabinets. It also possesses an
