Application
The new Nexans "GigaSwitch 641 Desk" is our next generation pure Gigabit Desktop switch system for FTTO applications.
Easy Installation
The very compact design of this switch allows easy integration on the desktop. Nexans is also providing the comfortable
kits for wall mounting of switch and external power supply.
Power over Ethernet - plus Capability
The Switch provide the PoE plus High Power up to 30 Watts on each of 4 users ports. This function allows to supply the
Ethernet devices with higher demands on consumption. The new Nexans Switch could provide up to 120 Watts for such
services.
10/100/1000 Mbps user ports with Energy Efficient Ethernet (EEE)
The key feature of the new GigaSwitch series is support for Energy Efficient Ethernet (EEE) which is standardized as the
802.3az standard. All Twisted Pair Ports are Energy Efficient Ethernet compliant and automatically shutting down the ports
in case of shut down or reducing of Ethernet traffic. The Network can benefit from lower power consumption, which redu-
ces energy costs and lowers overall operating costs for IT equipment.
Memory Card
The optional Memory Card always stores the complete and most actual configuration of the switch automatically. In case
of a system exchange you just need to take out the Memory Card of the old switch and insert it into the new switch. During
the boot process the new switch will then take over the old configuration from the Memory Card. Furthermore each Memory
Card has got its own MAC Address. As soon as a Memory Card is inserted into a system, the active MAC address is the
MAC Address of the Memory Card, i.e. there is no need to change routing tables in case of a system exchange!

In addition to the IP parameters the following temporary switch settings are made:
• All ports in the same VLAN
• Trunking disabled for all ports
• Admin state disabled for all ports
• Link Setup set to Autonegotiation / Autocrossover for all ports
• Portsecurity disabled for all ports
• Rapid Spanning Tree global disabled
The above settings ensure that the switch can be accessed via any port using the fixed IP address 172.23.44.111. Moreover
the IP, Link, VLAN, trunking and Portsecurity settings can be made without these settings taking immediate effect. Only after
a “Booting with Flash Configuration” the stored configurations will be enabled.
Moreover the fixed IP address can be used to check the configuration of the switch (e.g. if the switch cannot be accessed
via the expected IP address because of badly configured VLANs etc.).
Booting with Fixed IP Address
This function will enable the following temporary IP settings:
• IP-address 172.23.44.111
• Network mask 255.255.255.0
The switch can then be accessed via this temporary IP address in order to configure the required switch
parameters (e. g. the IP address).

Many problems occurring in data networks can be avoided. Based on many years of practical experience we can recomm-
mend the following settings for the switch systems:
Standard settings (equivalent to the default setting):
All TP ports: AN
All 100 Mbps FO ports: 100 FDX
All 1000 Mbps FO ports: 1000 FDX
PoE(PSE): IEEE802.3at (Power over Ethernet)
These settings offer the following advantages:
1. Collision-free full-duplex data transmission on fiber optic ports at maximum performance and maximum distance.
2. All common TP terminal configurations are supported in a practice-oriented way:
a. Auto-Negotiation: default setting of newer terminal units
(automatically set to 1000 Mbps, 100 Mbps or 10 Mbps full-duplex)
b.100 Mbps-Full-Duplex: for (mostly older) terminal units having problems with autonegotiation
c. 10 Mbps-Half-Duplex: for all terminal units supporting only 10 Mbps
3. PoE (PSE) feature according to IEEE802.3at is enabled by default - standard-compliant PoE (PD) terminal units or
switch systems are automatically supplied with power. All other terminal units automatically receive no PoE power and
are thus protected from being damaged.
Setting of connected FO switches (central, remote):
FO switch should always be set to 1000 Mbps full-duplex (FDX) or 100 Mbps (FDX) respectively. Full bandwidth and opti-
mum performance due to non-occurrence of collisions. No length restrictions due to cable delays.
Setting of connected TP switches (central, remote):
Attached switches with TP connections should be set to autonegotiation, just as terminal units. The automatic setting to 1000
Mbps (FDX) and 100 Mbps (FDX) also guarantees full bandwidth and maximum performance up to a line length of 100m.
Power over Ethernet is an attractive and standardized alternative for the power supply of LAN equipment such as VoIP pho-
nes, Wireless Access Points, video cameras etc., while using the "normal" Ethernet standard cable, i. e. without any addi-
tional cable tangle.
Function
An active source (PSE) ensures the power supply of a passive IEEE802.3at-compliant powered device (PD). The standard
defines 3 modes of operation for power supply, which is ensured via different wire pairings of the TP data connection:
• Endpoint PSE mode A - power supply via TP pairs 1/2 and 3/6
• Endpoint PSE mode B - power supply via TP pairs 4/5 and 7/8
• Midspan PSE mode B - power supply through an external device via TP pairs 4/5 and 7/8
The PoE solution will only supply power if an appropriate powered device (PD) is detected. The following functions are
checked prior to enabling PoE power supply:
• The active PSE source identifies the powered device (PD).
• The operational mode is detected.
• The required power class is detected on the basis of the classification current.
Thus any damages can be avoided, if the connected terminal unit is not standard-compliant.
Setting the transmission parameters
Power over Ethernet (PoE)

Page 11
Basics
Telephone helpdesk: [phone]
Power over Ethernet (PoE) is categorised into 5 power classes which are supported accordingly
The Nexans GigaSwitch Series is offering PoE (PSE) functionalities. The systems are therefore in a position to supply devices
according to IEEE802.3at - Endpoint PSE mode "Mode A". For external power supply (PSE) of devices an operation volta-
ge of more than 46 VDC for IEEE802.3af and 50 VDC for IEEE802.3at is needed.
Note
In any case please check the correct pin assignment and the correct polarity of the PoE wiring at the terminal unit.

Frequently Asked Questions (FAQs)

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?
How can the configuration be transferred to the new system after a
possible system failure?
How is the conversion from fiber to copper realized?
Do the systems require a power supply?
What if the backbone data rate changes?
How can the initial configuration be performed?
Can IP cams or wireless access points and similar devices be powered
via the switch?

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.
WEB, TELNET, SSH and SNMP management interfaces are also supported. The integration into higher management systems
like HP Openview, Spectrum, etc. is further made 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 poss-
sible total failure of the link. Appropriate messsages (SNMP traps, Syslog) can also be sent to a central management system.
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 switch 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.
All switch systems support the Rapid Spanning Tree Protocol (RSTP). The RSTP guarantees the automatic and fast switcho-
ver to a redundant link in the event of the failure of a transmission link. This feature clearly improves the availability of the
network!
