NOTE 

By default, the EDS is configured to limit broadcast packets not to exceed 8M to protect against 
broadcast storms caused by careless usage. This value can be adjusted by the user. 

Since industrial Ethernet devices are often located at remote areas of a system, these devices will 
not always know what is happening elsewhere on the network. This means that an industrial 
Ethernet switch that connects to these devices must provide system maintainers with real-time 
warning messages. Even when control engineers are out of the control room for an extended 
period of time, they can still be informed of the status of devices almost instantaneously when 
exceptions occur. The EDS supports different approaches such as email and relay output to warn 
engineers automatically. 

Configuring Email Warning 

The Auto Email Warning function uses e-mail to alert the user when certain user-configured 
events take place. 

Three basic steps are required to set up the Auto Warning function: 

1. 

Configuring Email Event Types 
Select the desired Event types from the Console or Web Browser Event type page (a 
description of each event type is given later in the Email Warning Events setting subsection).
