Basically the cabling infrastructures in buildings are strongly affected by technology changes. Approximately every 5 years the
network data rates are increasing by a factor of 10. Therefore a future proof network infrastructure is indispensable in order
to ensure an investment protection. A continuous "FttO - Fiber to the Office" cabling infrastructure is an optimum solution.
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 Switch systems are equipped with an integrated memorycard 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
memorycard from the old switch, insert it into the new switch, and the configuration will automatically be mirrored to the new
device. The switch can be booted with the MAC address of the memoryx card, so the superior address tables (e.g. in
routers) all remain unaffected.
By using Nexans GigaSwitch Systems a standard complying conversion from fiber to copper can be realized easily. The
systems are designed for an installation in cable ducts or floor boxes. They have got up to 2 uplink interfaces on the reverse
side and four twisted pair user interfaces on the front side.
Active systems always require a power supply. The Nexans GigaSwitch Systems can be operated with a centralized or decen-
tralized 48VDC power supply. This 48 VDC power supply can also be used to supply the connected Power over Ethernet
terminal equipment simultaneously. Thanks to the implemented Power-over-Ethernet (PoE)-Functionalities e.g. VoIP-Phones,
Wireless-Access-Points and IP-Cameras can be supplied with power from the switch system directly. External power supp-
plies for the connected terminal equipment are no longer needed.
Power Source Equipment (PSE)
The implemented manageable Power over-Ethernet (PoE) feature 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.
Investment Protection
The Nexans Systems are offering a very high level of investment protection. The SFP uplink interface of the GigaSwitch
system can be equipped with a Fast Ethernet SFP or a Gigabit SFP module. In case of a data rate change from 100 Mbps
to 1000 Mbps you only have to change the SFP transceiver module. A system exchange is not necessary!
In order to ensure simple configuration and management of these devices, Nexans has designed an easy to use tool spe-
cifically tailored to the requirements of the user. The Nexans Switch Manager NexMan V3 ensures the automated distribu-
tion 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 configu-
rations in a database. In case of failure, this key feature will ensure the rapid reconfiguration of the switch parameters and
minimize downtime.
Where are these systems typically used?
