WESTERMO SDW-532-MM-SC2-SM-SC15 (01) PDF Document

Before installation, read the 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).

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.

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:

• 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 WESTERMO SDW-532-MM-SC2-SM-SC15 is auto configured (auto-negotiation) or allows 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-SC2-SM-SC15 includes Multi-mode and Single-mode fibre ports. The relevant specifications for the ports on the WESTERMO SDW-532-MM-SC2-SM-SC15 are as follows:

Features:

• 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

Example of applications are:

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

The WESTERMO SDW-532-MM-SC2-SM-SC15 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.

Ethernet TX connection (RJ-45 connector), automatic MDI/MDI-X crossover.

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

Ethernet FX connection. 1300 nm multi- or singlemode fibre tranceiver with SC-connector. The dust protection plug shall be mounted when no fibre is connected.

Ethernet FX connection. 1300 nm multi mode fibre tranceiver with ST-connector. The dust protection plugs shall be mounted when no fibre is connected.

Ethernet FX connection. 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.

Indicators (LED):

• Power (PWR)
• Link (LINK) of every port
• 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. When configuration via DIP-switches, the settings of DIP-switches configure the unit only after a reboot (power off/on).

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.

To be observe 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.
