The most common initial configuration step is to apply static IP addresses to your network ports. QuantaStor will initially get an IP address from your DHCP server but this is intended only to assist with the initial setup and installation process. DHCP allocated IP addresses can change so they're not to be used with your storage system unless you've statically assigned DHCP addresses. Even then we don't recommend the use of DHCP as your system needs to be able to boot even if the DHCP server is offline or inaccessible.
This can be completed quickly using the Network Configuration button in the Manager, but also can be found via right-clicking inside the Network Ports tab, visible when "Storage System" is selected under "Storage Management".
