What safety precautions should be taken before installing the WESTERMO SDW-532-SM-LC15?
Before installation:
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).

Where are the DIP-switches located on the WESTERMO SDW-532-SM-LC15, and what must be observed when configuring them?
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.
NOTE: When configuration via DIP-switches, the settings of DIP-switches configure the unit only after a reboot (power off/on).
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.
