WESTERMO SDW-532-MM-LC2 (01) PDF Document

Before installation, you should:

• Read this manual completely and gather all information on the unit. Make sure that you understand it fully. Check that your application does not exceed the safe operating specifications for this unit.
• This unit should only be installed by qualified personnel.
• This unit should be built-in to an apparatus cabinet, or similar, where access is restricted to service personnel only.
• The power supply wiring must be sufficiently fused, and if necessary it must be possible to disconnect manually from the power supply. Ensure compliance to national installation regulations.
• This unit uses convection cooling. To avoid obstructing the air flow around the unit, follow the spacing recommendations (see Installation section).

Before mounting, using or removing this unit:

• Prevent access to hazardous voltage by disconnecting the unit from power supply.
• Warning! Do not open connected unit. Hazardous voltage may occur within this unit when connected to power supply.

Class 1 Laser Product: Do not look directly into fibre optical fibre port or any connected fibre although this unit is designed to meet the Class 1 Laser regulations.

Follow the care recommendations below to maintain full operation of unit and to fulfil the warranty obligations.

• This unit must not be operating with removed covers or lids.
• Do not attempt to disassemble the unit. There are no user serviceable parts inside.
• Do not drop, knock or shake the unit, rough handling above the specification may cause damage to internal circuit boards.
• Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
• Do not paint the unit. Paint can clog the unit and prevent proper operation.
• Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not waterproof. Keep the unit within the specified humidity levels.
• Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical part may be damaged.
• Fibre connectors are supplied with plugs to avoid contamination inside the optical port. As long as no optical fibre is mounted on the connector, e.g. for storage, service or transportation, should the plug be applied.

Fibre optic equipment needs special treatment. It is very sensitive to dust and dirt. If the fibre will be disconnected from the modem the protective hood on the transmitter/receiver must be connected. The protective hood must be kept on during transportation. The fibre optic cable must also be handle the same way.

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

No maintenance is required, as long as the unit is used as intended within the specified conditions.

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 this 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 is auto configured (auto-negotiation) or done by 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.

The WESTERMO SDW-532-MM-LC2 supports redundant power connection. The positive input are +VA and +VB, the negative input for both supplies are COM. The power is drawn from the input with the highest voltage.

The Ethernet TX connection supports automatic MDI/MDI-X crossover. CAT 5 cable is recommended. Unshielded (UTP) or shielded (STP) connector might be used.

The Ethernet FX connection uses 1300 nm singlemode fibre transceiver with LC-connector. The dust protection plug shall be mounted when no fibre is connected.

At power on the PWR flashes during initialising. The indicators (LED) are Power (PWR), Link (LINK) of every port, and Speed (SPD) and duplex (DPX) of TX ports.

DIP-switches are accessible under the lid on top of the unit. DIP-switches are used to configure the unit.

Warning! Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap), before the lid on top/front of the unit is removed.

Warning! Do not open connected equipment. Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections.

When configuration via DIP-switches, the settings of DIP-switches configure the unit only after a reboot (power off/on).

• Speed and duplex setting only valid when auto-negotiation is disabled.
• When monitoring selected all outgoing packets from the switch is also copied to the port 1.
• Speed and duplex switch settings are ignored for FX ports.
• If auto-negotiation and auto MDI/MDI-X disabled all TX ports support MDI-X configuration.

These settings are ignored when using the WESTERMO SDW-532-MM-LC2 (SDW-532 models).

Before mounting or removing the unit:

• Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap).
• Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections.

This unit should be mounted on 35 mm DIN-rail which is horizontally mounted on a wall or cabinet backplate.

This unit uses convection cooling. To avoid obstructing the airflow around the unit, use the following spacing rules. Recommended spacing 25 mm (1.0 inch) above/below and 10 mm (0.4 inches) left/right the unit. The 10 mm spacing left/right is recommended for full operating temperature range.

Mounting is done by snapping the unit onto the DIN-rail.

Press down the black support at the back of the unit to remove it.
