Safety Information

Before installation:
Read this manual completely and gather all information on the product. Make sure that you understand it fully. Check that your application does not exceed the safe operating
specifications for this product.

WARNING – SAFETY DURING INSTALLATION
The product must be installed and operated by qualified service personnel and installed into an apparatus cabinet or similar, where access is restricted to service personnel only.

During installation, ensure a protective earthing conductor is first connected to the protective earthing terminal (only valid for metallic housings). Westermo recommends a cross-sectional area of at least 4 mm2.

If the product does not have a protective earthing terminal, then the DIN-rail must be connected to the protective earth. Upon removal of the product, ensure that the protective earthing conductor, or the connection to earth via the DIN-rail, is disconnected last.

WARNING – HAZARDOUS VOLTAGE

Do not open an energized product. Hazardous voltage may occur when connected to a power supply.

WARNING – PROTECTIVE FUSE
The power supply wiring must be sufficiently fused. It must be possible to disconnect manually from the power supply. Ensure compliance with national installation regulations.
Replacing the internal fuse must only be performed by Westermo qualified personnel.

WARNING – REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords with a cable diameter of AWG 26 or larger. Regarding power cable dimensions, see Interface Specifications.

CAUTION – CLASS 1 LASER PRODUCT
Do not look directly into a fiber optical port or any connected fiber, although the product is designed to meet the Class 1 Laser regulations and complies with 21 CFR 1040.10 and 1040.11.

CAUTION – FIBRE OPTIC HANDLING

Fiber optic equipment needs special treatment. It is 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.

CAUTION – CORROSIVE GASES
If the product is placed in a corrosive environment, it is important that all unused connector sockets are protected with a suitable plug, in order to avoid corrosion attacks on the gold-plated connector pins.

CAUTION – ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damages to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).

Care recommendations

Follow the care recommendations below to maintain the full operation of the product and to fulfill the warranty obligations:

Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.
Use a dry or slightly water-damp cloth to clean the product. Do not use harsh chemicals, cleaning solvents or strong detergents.
Do not paint the product. Paint can clog the product and prevent proper operation.

If the product is used in a manner not according to specification, the protection provided by the equipment may be impaired.
If the product is not working properly, contact the place of purchase, nearest Westermo distributor office or Westermo technical support.

Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by the use of forced nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:

Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
Hexane
Naphtha

Product disposal

This symbol means that the product shall not be treated as unsorted municipal waste when disposing of it. It needs to be handed over to an applicable collection point for
recycling electrical and electronic equipment.

By ensuring the product is disposed of correctly, you will help to reduce hazardous substances and prevent potential negative consequences to both environment and human
health, which could be caused by inappropriate disposal.

Configuration
Auto configured (auto-negotiation) or manually setting of speed and duplex of individual TX port, by DIP-switches. Port mirror function is possible to set with DIP-switch. With the port mirror function active the switch will copy all outgoing traffic to port 1. This can be used to monitor all traffic going out from the switch. Packets may be discarded if the total throughput exceeds the port speed of port 1.

Description
The SDW-541-F1G-T4G is an unmanaged 5-port switch with one SFP fiber port supporting 100 Mbit/s or Gbit Ethernet, and four copper ports supporting 10/100 Mbit/s or Gbit Ethernet. The Westermo range of 100 Mbit or Gbit Small Form-factor Pluggable (SFP) transceivers are available as multimode, single- mode, or Bi-Di transceivers with
distance up to 120 km.

WESTERMO Industrial Ethernet 5-port Switch SDW-500 - VDC
power

The SDW-550-T5G is an unmanaged 5-port switch with five copper ports, all supporting 10 Mbit/s, 100 Mbit/s, or Gbit Ethernet. Both are designed for easy use in heavy-duty industrial, maritime, and rail trackside applications. The units support 802.1Q long packets which allow all standard industrial Ethernet protocols to be used.

The units are designed for use in industrial applications with dual 9.6 to 57.6 VDC power input. The unique “tri-galvanic” isolation provides isolation between all ports, power supply, and between each chassis screen avoiding ground loop currents. The IP21 rating ensures that the unit can be installed in locations where condensed water may occur. Only industrial grade components are used which gives an MTBF of 1.182.000 hours for the SDW-541-F1T4G and 1.121.000 hours for the SDW-550-T5G and thus ensures a long service life. A wide operating temperature range of –40 to +74 °C (–40 to +165 °F) can be achieved with no moving parts.

The units have been tested both by Westermo and external test houses to meet EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial, trackside, and maritime environments.

Network diagnostics are simplified with the inclusion of port mirroring on one port allowing data flow through the switch to be monitored using a network analyzer. All five ports can have data rate and flow control locked by DIP switch which can eliminate problems with old legacy Ethernet equipment that is unable to support auto-negotiation.
