WESTERMO SDW-550 (01) PDF Document

Before installation of the WESTERMO SDW-550, read the manual completely and gather all information on the unit. Make sure you understand it fully and check that your application does not exceed the safe operating specifications for this unit. This unit should only be installed by qualified personnel. It 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).

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.

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 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 handle the same way. If this recommendation not will be 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:

• 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.

The environmental specifications for the WESTERMO SDW-550 series are:

The mechanical specifications for the WESTERMO SDW-550 are:

Configuration for the WESTERMO SDW-550 can be set:

• 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.

The Fibre optic power budget for models in the WESTERMO SDW-500 series is detailed below. Note that the SDW-550 is equivalent to the Multimode MM-xx2 in this table for power budget comparison.

The normal attenuation in connectors/splices for the WESTERMO SDW-500 series is:

The power specifications for the WESTERMO SDW-500 series are:

The Ethernet TX electrical specifications for the WESTERMO SDW-500 series are:

The Ethernet FX electrical specifications for the WESTERMO SDW-500 series are:

The WESTERMO SDW-500 series 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 connections via the 3-pos screw terminal are:

The Ethernet TX connection on the WESTERMO SDW-550 uses an RJ-45 connector and features automatic MDI/MDI-X crossover. The contact pinout is:

CAT 5 cable is recommended. Unshielded (UTP) or shielded (STP) connector might be used.

The FX SC Multi- or single mode connection on the WESTERMO SDW-550 is an Ethernet FX connection using a 1300 nm multi- or singlemode fibre transceiver with SC-connector. The dust protection plug shall be mounted when no fibre is connected.

The FX ST Multi mode connection on the WESTERMO SDW-550 is an Ethernet FX connection using a 1300 nm multi mode fibre transceiver with ST-connector. The dust protection plugs shall be mounted when no fibre is connected.

The FX LC Multi- or single mode connection on the WESTERMO SDW-550 is an Ethernet FX connection using a 1300 nm singlemode fibre transceiver with LC-connector. The dust protection plug shall be mounted when no fibre is connected.

The PWR LED indicators on the WESTERMO SDW-550 signify the following:

The LINK LED indicators on the WESTERMO SDW-550 signify the following:

The SPD and DPX LED indicators on the TX only ports of the WESTERMO SDW-550 signify the following:

DIP-switches on the WESTERMO SDW-550 are accessible under the lid on top of the unit and are used to configure the unit.

Safety Precautions:

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

Note:

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.

To mount the WESTERMO SDW-550:

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), and 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 a 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. Snap on mounting, see figure.

To remove the WESTERMO SDW-550:

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), and prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supply and all other electrical connections.

Press down the black support at the back of the unit, see figure.
