Product Description

L206-F2G-EX is an industrial switch made for harsh environments. The switch can be used in either 100 Mbit or Gigabit networks due to our multi-rate SFP solution. L206- F2G-EX can also be used together with our previous Lynx series of switches.
Our unique FRNT (Fast Recovery of Network Topology) technology is the fastest protocol on the market to re-configure a network in the event of any link or hardware failure.  That is why our products are used in safety-critical applications such as tunnels, traffic signal control, and railway systems.
Installations in harsh environments and places with heavy electrical interference require the use of reliable media. Lynx provides a number of solutions using fiber optic transceivers.
Multi- or single-mode transceivers can be used to build point-to-point or redundant ring networks with ranges up to 120 km between each switch. Our BIDI transceiver, which transmits and receives data on a single fiber can be used in applications where the number of fiber cores is limited.
Real-time properties are implemented in the switch in order to achieve determinism for real-time-critical applications. Lynx supports QoS (Quality of Service) with four priority queues and strict priority scheduling as well as HoL (Head of Line Blocking Prevention).
All to assure that the data network is deterministic.

Hardware Overview

Location of interface ports and LEDs

Interface specifications

* Recommended external supply current capability for proper startup

* Refer to Safety section.
** To minimize the risk of interference, a shielded cable is recommended when the cable is located inside a 3 m boundary or the cable is longer than 30 m and inside a 10 m  boundary to the rails and connected to this port.

SFP Transceivers
The product supports UL and IEC-certified transceivers only. See Westermo’s modular transceivers datasheets 100 Mbit and 1 Gbit for supported SFP transceivers, which can  be downloaded from the product support pages at www.westermo.com/support/productsupport.

Each SFP slot can hold one SFP transceiver. See “Transceiver User Guide 6100-0000” for transceiver handling instructions, which also can be downloaded from the product support pages at www.westermo.com/support/product-support.
In the event of contamination, the optical connectors in the SFP transceivers should only be cleaned by the use of forced nitrogen and some kind of cleaning stick.  recommended cleaning fluids are methyl-, ethyl-, isopropyl- or isobutyl alcohol, hexane or naphtha

Supported transceivers
Firmware prior to 4.4.0 accepts Westermo branded transceivers only. From 4.5.0 other transceivers are accepted with notice and the product will no longer be UL approved.
Temp. specifications are also depending on the used transceivers.
Note: To comply with UL 62368-1, only UL recognized SFP transceivers should be used.

CAUTION – HANDLING OF SFP TRANSCEIVERS
SFP transceivers are supplied with plugs to avoid contamination inside the optical port. They are very sensitive to dust and dirt. If the fiber is disconnected from the product,  the protective plugs on the transmitter/receiver must be connected. The protective plugs must be kept on during transportation. The fiber optics cables must be handled the same way.

Factory default on L206-F2G EX

It is possible to set the product to factory default settings by using two straight standard
Ethernet RJ-45 cables.

1. Power off the switch and disconnect all Ethernet cables (copper and fiber).
2. Connect one Ethernet cable between Ethernet ports 3 and 6, and the other between Ethernet ports 4 and 5.
   The ports need to be connected directly by an Ethernet cable, i.e., not via a hub or switch. Use a straight cable – not a cross-over cable – when connecting the ports.
3. Power on the product.
4. Wait for the product to start up. Control that the ON LED is flashing red.
   The ON LED flashing indicates that the product is now ready to be reset to factory default. You now have the choice to go ahead with the factory reset, or to skip factory reset and boot as normal.
   • Go ahead with factory reset:
   Acknowledge that you wish to conduct the factory reset by unplugging the Ethernet cables. The ON LED will stop flashing.
   This initiates the factory reset process*, and the product will restart with factory default settings. When the switch has booted up, the ON LED will show a green light, and is now ready to use.
   • Skip the factory reset:
   To skip the factory reset process, just wait for approximately 30 seconds (after the ON LED starts flashing RED) without unplugging the Ethernet cables.
   The switch will conduct a normal boot with the existing settings.

Note
Do not power off the product while the factory reset process is in progress.
