Administration & System Options AXIS 250S User’s Manual32Network TrafficThis can be used to change the network speed for your server. Normally, there is no need touse anything other than Auto-negotiate, which will automatically select the correct mediatype. However, if you are using a switch or similar device on your network and need tospecify the media type, then this can be done by selecting the correct type from thedrop-down list.SMTP (email) Network SettingsThe AXIS 250S can be configured to send event and error email messages to predefinedaddresses.Primary mail server - Enter the name or IP address of the server providing your mail facilities.Note that to use a host name, a DNS server must be specified in the TCP/IP networksettings.Secondary mail server - Enter the name or IP address of a secondary mail server. This will beused if the primary mail server is unavailable.Send test email to - test the setup by clicking the Send button.Ports & DevicesIO PortsThis page allows you to enable and configure the four inputs and one output supported bythe server. Ports can be enabled or disabled, given descriptive names, and their Normalstate can be configured.The normal state describes the inactive state for the port. It is also an indication of thefunction of the connected equipment and how it is activated. For example, if the activationcircuit in a door switch connected to an input is normally closed, this means that as long asthe door is closed then the state is also closed (inactive). When the door is opened the doorsensor will be active and the input will no longer be in its normal state. This is how eventsbased on external equipment are triggered.Thus, in the I/O port list, if the Normal state for an input is set as Open, but the Currentstate is shown as Closed, then the port has been activated, and vice versa.Important!Please note that some external devices may behave incorrectly in the event of an errorcondition, e.g. a power cut.
