Commissioning
This is a forward link to the Site Commissioning guide. During Site Commissioning, settings for the eSite Modular system are finalized upon installation. The Site Commissioning makes sure that the eSite Modular system is set up correctly and operates as intended. Moreover, the Site Commissioning guide is where all RE/RSE/SE Converter Units are registered and unregistered. Detection of a connected, unregistered unit automatically starts the Site Commissioning guide. To unregister a registered Converter Unit, please enter the Site Commissioning guide from this menu
Add an extra ip address to eth0. Use syntax: where x is the IP address and nn is the subnet mask in Linux notation (24 = mask 255.255.255.0).
