WESTERMO SDW-541-SM-SC15 (01) PDF Document

Before installing the WESTERMO SDW-541-SM-SC15, you should read the manual completely and gather all information on the unit. Make sure that 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 and 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 the fibre optical 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.

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 are:

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 DIP-switch settings for Port 4 on the WESTERMO SDW-541-SM-SC15 (SDW-541) are controlled by S2 switches 1 through 5:

Note: These settings are ignored when using SDW-532.

Port mirroring settings on the WESTERMO SDW-541-SM-SC15 are configured using S2 switches 6 through 8:

When monitoring is selected, all outgoing packets from the switch are also copied to port 1.

Flow control settings are configured using S3 switches 1 through 4:

The factory settings for the DIP-switches on the WESTERMO SDW-541-SM-SC15 are:

S1: All switches OFF (1-8)

S2: All switches OFF (1-8)

S3: All switches OFF (1-4)

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.
