WESTERMO SDW-532-SM-SC15 (01) PDF Document

Follow the care recommendations below to maintain full operation of the WESTERMO SDW-532-SM-SC15 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.
• If the unit is not working properly, contact the place of purchase, nearest Westermo distributor office or Westermo Tech support.
• 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 handled the same way.

If this recommendation is not followed it can jeopardise the warranty.

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 are:

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

No maintenance is required, as long as the WESTERMO SDW-532-SM-SC15 is used as intended within the specified conditions.

The symbol on the product 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.

The environmental conditions for the WESTERMO SDW-532-SM-SC15 are as follows:

Isolation between interfaces:

Environmental:

Mechanical:

The WESTERMO SDW-532-SM-SC15 is auto configured (auto-negotiation) or through 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 Fibre optic power budget specifications for the WESTERMO SDW-532-SM-SC15 (Singlemode SM-SC15) are:

The Attenuation in connectors / splices specifications are:

• TX shields individually isolated
• Wide DC power range 12 – 48 VDC
• Wide temperature range
• Automatic MDI/MDI-X crossover
• LED indicators for Power, Speed, Duplex, Link and Traffic
• Port monitoring
• 35 mm DIN rail mounting
• Enable or disable of flow control

Examples of applications are:

• 5-port switch
• Ethernet isolator, for STP networks

The power specifications for the WESTERMO SDW-532-SM-SC15 are:

The Ethernet TX interface specifications are:

The Ethernet FX interface specifications are:

The WESTERMO SDW-532-SM-SC15 supports redundant power connection. The positive inputs are +VA and +VB, and the negative input for both supplies is COM. The power is drawn from the input with the highest voltage. The 3-pos screw terminal connections are:

The Ethernet TX connection is an RJ-45 connector with automatic MDI/MDI-X crossover. CAT 5 cable is recommended. Unshielded (UTP) or shielded (STP) connector might be used. The contact assignments are:

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

The FX LC Multi- or single mode connection is for Ethernet FX. It 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 (LEDs) include Power (PWR), Link (LINK) of every port, and Speed (SPD) and Duplex (DPX) of TX ports. The indications are:

DIP-switches are accessible under the lid on top of the unit. DIP-switches are used to configure the unit. When configuration via DIP-switches, the settings of DIP-switches configure the unit only after a reboot (power off/on).

To be observed when the DIP-switches will be configured:

• 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.

The factory settings for the DIP-switches are:

• S1: All switches are ON (up).
• S2: All switches are ON (up).
• S3: All switches 1, 2, 3, 4 are ON (up).

Before mounting or removing the WESTERMO SDW-532-SM-SC15:

• 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.

The WESTERMO SDW-532-SM-SC15 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. Mounting is done by snapping it onto the DIN-rail.

To remove the WESTERMO SDW-532-SM-SC15, press down the black support at the back of the unit.
