Industrial Ethernet (FAQs)
Where are these systems typically used? Fields of application include security, (e. g. video surveillance at airports, hotels, hospitals, schools, etc.), the control of machines, the remote monitoring of power meters (e.g. automatic metering), and the networking of transformer substations. Traffic management applications and the control of wind turbines are just a few
further examples of the diverse applications of the Nexans iSwitch systems. |
How can the initial configuration be performed? In order to ensure simple configuration and management of these devices, Nexans has designed an easy to use tool specifically tailored to the requirements of the user. The Nexans Switch Manager NexMan V3 ensures the automated distribution of master configurations and software updates to any number of industrial switches. Distribution of the complete or partial configuration is all possible. Another important feature of NexMan V3 is the central archiving of all switch configurations in a database. In case of failure, this key feature will ensure the rapid reconfiguration of the switch parameters and minimize downtime. |
How can the systems be monitored? NexMan V3
The NexMan V3 user interface provides the administrator with a complete overview of the current state and accessibility of the switch systems available in the network. By simply selecting a switch system, you can set several parameters such as port configuration, SNMP trap receiver, 802.1x, Radius, and many more.
The user does not need to have knowledge of complex management software systems in order to perform this function. |
What management interfaces are supported? WEB, TELNET, SNMP and V.24 management interfaces are also supported. The integration into higher management systems like HP Openview, Spectrum, etc. is further made possible. |
Is the early detection of changes on the optical link possible? A multitude of parameters can be read out from systems with SFP interface via the management system. Changes in the link characteristics (e.g. attenuation increases) can be detected and resolved on the basis of threshold values prior to a possible total failure of the link. Appropriate messages (SNMP traps, Syslog) can also be sent to a central management system. |
How can faults be detected on a twisted-pair cable link? Cable Diagnostic Function
The iSwitch 7xx and 10xx series ensures the easy and fast localization of possible faults on the copper twisted-pair cable links. Identification of short circuits, interruptions, impedance mismatches or reversals, can be localized to the meter via the management feature.
|
Can IP cams or wireless access points and similar devices be powered via the switch? The implemented manageable Power over-Ethernet (PoE) feature (optional) makes it further possible to power e. g. IP cameras, wireless access points, VoIP phones or multifunctional terminals directly via the switch system. Thereby, the user does not need any plug-in power supplies for the terminal units. |
Can the switch itself be powered via the RJ45 socket? All systems can also be supplied with power via an RJ45 external connection. This enables the systems to be used at remote locations where no 24VDC or 48VDC power supply is available. |
How can the configuration be transferred to the new system after a possible system failure? The Nexans systems provide a unique concept for the recovery of the complete system configuration. This allows untrained staff to easily reconfigure the system after a failure. All iSwitch systems are equipped with an integrated MMC card slot through which the complete system configuration may be saved as a backup copy. In the event of a failure, the user only needs to swap out the MMC card from the old switch, insert it into the new switch, and the configuration will automatically be mirrored to the new device. As an option the switch can even be booted with the MAC address of the MMC card, so the superior address tables (e.g. in routers) all remain unaffected. |
How do you prevent unauthorized access to network? Nexans Switch systems support all relevant security mechanisms such as IEEE802.1x and MAC-based access control. In connection with a central authentication server, e.g. RADIUS, security in enterprise networks is considerably improved. Maximum security is achieved by access control directly at the user port of the Nexans iSwitch system. Thus the identity of the client is verified directly at the connection point and not only at the bundled port of the central switch.
Any potential abuse of the network connection, e.g. by listening in on traffic, is thus principally excluded. |
What happens in case of a link failure? All switch systems support the Rapid Spanning Tree Protocol (RSTP). The RSTP guarantees the automatic and fast switch- over to a redundant link in the event of the failure of a transmission link. This feature clearly improves the availability of the network! |
What happens in case of a power failure? The redundant power supply feature
further guarantees the operational safety of the systems. The systems can be powered with 24VDC or 48VDC. Power failures can be signaled via alarm contacts, SNMP traps or Syslog messages. |
