7900 Series Modular Industrial Ethernet Switch
N-Tron Networking Series
Modular Industrial Switch
The N-Tron® 7900 Industrial Ethernet Modular Switch is designed to
deliver opꢀmum performance with maximum network versaꢀlity. Its
exible modular format allows customizaꢀon with a variety of ber and
copper port modules. As the network evolves, port conguraꢀons can
easily be changed to adapt to new communicaꢀon requirements. The
fully managed series is ideal for manufacturing, uꢀliꢀes, transportaꢀon,
energy generation, wastewater and other extreme networking
environments that demand high reliability, superior noise immunity and
support across extended distances.
PRODUCT FEATURES
• 4 slot modular switch
• Requires 2 SFP gigabit CPU module (transceivers sold separately)
• Available modules (transceivers sold separately):
- 2 port 100BaseFX ber module
- 4 port 100BaseFX ber module
REMOTE MONITORING OPTIONS
- 6 port 10/100BaseTX copper module
Web browser and N-View OPC (OLE for process control) server so�ware
provides configuration and monitoring capability. N-View software
easily combines with HMI so�ware to monitor network traffic, alarms
and trends. SNMP is also available for switch link and status monitoring.
Status LEDs are congurable to indicate power failure and N-Ring status.
• -20oC to 70oC operaꢀng temperature
• Onboard temperature sensor
• ESD and surge protecꢀon diodes on all copper ports
• Auto sensing 10/100BaseTX, duplex and MDIX
• Store-and-forward technology
N-RING TECHNOLOGY
• Rugged DIN-rail enclosure
Advanced N-Ring technology provides expanded capacity, detailed fault
diagnosꢀcs and fast ~30ms healing ꢀmes in rings composed of N-Tron fully
managed switches. The integrity of the N-Ring is conꢀnually monitored for
error condiꢀons. If a fault is detected, the ring converts to a daisy chain
topology and restores communicaꢀons within ~30ms. For convenience,
users can easily access a detailed ring map and fault locaꢀon chart through
the ring manager's browser or the OPC server. Each N-Ring accommodates
up to 250 fully-managed N-Tron switches. N-Link easily connects mulꢀple
rings, creaꢀng addiꢀonal pathways to criꢀcal applicaꢀons and increasing
overall network resiliency.
• Redundant power inputs (10-30 VDC)
• Congurable bi-color fault status LEDs
FULLY MANAGED FEATURES
• SNMP v1, v2, v3 and web browser management
• EtherNet/IP™ CIP Messaging
• Conguraꢀon backup via opꢀonal SD card (order NTCD-128)
• Detailed ring map and fault locaꢀon charꢀng
• N-Ring™ Technology with ~30ms healing
• N-Link™ Redundant N-Ring Coupling
• N-View™ OPC monitoring
INDUSTRIAL SPECIFICATIONS
Standard industrial product features include high MTBF, extended shock
and vibraꢀon specicaꢀons, redundant power inputs and a wide operaꢀng
temperature range.
• RSTP - 802.1d, 802.1w, 802.1D
• IGMP auto conguraꢀon
• 802.1Q tagged VLAN and port VLAN
• 802.1p QoS, port QoS and DSCP
EASE OF USE
N-Tron's auto sensing capabilities allow all 10/100BaseTX ports to
automaꢀcally negoꢀate maximum speed and performance but can also
be hard coded using the user interface. A high-speed processor enables
simultaneous wire speed capability on all 100BaseTX ports.
• LLDP (Link Layer Discovery Protocol)
• DHCP Server, Opꢀon 82 relay, Opꢀon 61, IP Fallback
• Port mirroring and trunking
• Local Port IP Addressing
• Port Security—MAC Address Based
