Management Features
The 708M12-HV offers several management functions that can
be easily confi gured using a web browser.
IGMP Snooping - Internet Group Management Protocol allows
the switch to forward and fi lter multicast traffi c intelligently.
VLAN - Virtual Local Area Network allows you to segment the switch
in order to create two or more separate local area network domains.
QoS - Quality of Service provides prioritization of network
traffi c in order to provide better network service. QoS improves
the latency of prioritized Ethernet packets required for ring
management, real-time, and other interactive applications.
Trunking - Trunking (link aggregation) enables multiple physical
ports to be linked together and function as one uplink to
another
manner, thereby increasing the bandwidth between switches. This
confi guration can provide increased bandwidth and redundancy
to applications requiring high levels of fault tolerant operation.
Port Mirroring - Allows the traffi c on one port to be duplicated
and sent to a designated mirror port. Port mirroring is used to
monitor Ethernet traffi c on the designated source port using the
assigned mirror port.

CIP Messaging
N-TRON trunking capable switch confi gured in the same
DHCP - DHCP Server/Client automates the assignment of IP
addresses. DHCP Option 82 assures that if a device on a specifi c
port is replaced, the replacement receives the same IP address as
the original device.
Rapid Spanning Tree - This function allows the switch to be
confi gured in a Ring or Mesh topology, and provides support for
redundant path communications with high-speed (rapid) healing.
Remote Monitoring Options
For ease of confi guration and monitoring, the 708M12-HV offers Web
Browser Management and N-View OLE for Process Control (OPC)
Server Software. The N-TRON N-View Software can be combined
with popular HMI software packages to add network traffi c monitoring,
trending, and alarming to any application using N-TRON switches.
In addition SNMP is available for switch link and status monitoring.
The 708M12-HV Switch Status LED can be confi gured to respond to
power failure on power input 1 or input 2, N-Ring Broken, Partial Break
High, Partial break Low, or if multiple Ring managers are detected.
N-Ring Technology
N-TRON's N-Ring technology offers expanded ring size capacity,
detailed fault diagnostics, and a standard healing time of ~30ms. The
708M12-HV Ring Manager periodically checks the health of the Ring
via packets. If the Ring Manager stops receiving these health check
packets, it converts the Ring to a linear bus topology within ~30ms. In
addition to standard Ring Manager protocol, when using all N-TRON
fully managed switches in the ring, a detailed ring map and fault location
chart will also be provided on the Ring Manager’s web browser and
OPC Server to identify the health status of the ring. Up to 250 fully
managed N-TRON switches can participate in N-Ring topologies.
Industrial Packaging and Specifi cations
The 708M12-HV is specifi cally designed to operate in industrial
environments. The rugged IP67 enclosure combined with extended
industrial specifications and features to meet or exceed the
operating parameters of the connected equipment. These include
extended temperature ratings, extended shock and vibrations specs,
redundant power inputs, and high MTBF (greater than 2M hours).
Ease of Use
The 10/100BaseTX ports are auto sensing and auto
configuring. Each copper port is automatically negotiated for
maximum speed and performance by default, but can also be
hard coded using the web browser. A high-speed processor allows
wire speed capability on all 100BaseTX ports simultaneously.
