How do I reset the Com-Server to its factory default settings?

- The standard way to recreate the factory default settings is by means of the Telnet configuration under port number 1111. After selecting the corresponding menu item in “System-Setup” and then
confirming with “Y”, the Com-Server closes the Telnet session, performs a reset and loads its factory settings. The IP address is then reset to 0.0.0.0, which allows you to reassign it using a static ARP entry (see also Note) - If the current IP address of the Com-Server ius unknown or if it doesn’t fit into its own network, the factory settings can also be restored through hardware. To do this, the board has 2 jumpers which are open (out) for normal operation. Proceed as follows:
– Turn off power to the Com-Server and open the housing.
– Close (insert) both jumpers.
– Restore power to the Com-Server.
– After a wait time of approx. 20 s, you can disconnect the power and open the jumpers again. The Com-Server is now reset to its factory default settings.
Closing the jumpers initializes a self-test which is designed for the W&T test bench and which will only run properly there. The serially output error messages can thus be ignored. The only critical feature here is the fact that the self-test always ends by restoring the factory default settings.
Note: For a possible check of whether the Com-Server is really switched to its factory settings, the dynamic ARP entry previously generated by the last Telnet session must first be deleted. If this is not done, the Com-Server takes destination IP address contained in the first of the packets directed to its MAC address and stores it as its own.
Command for deleting an ARP entry: arp -d [IP address]
