NOTE:
Intel RAID Web Console2 may not operate correctly due to tool bug ( only last Ethernet port position will work.
Example: From Eth0, Eth1, Eth2 and Eth3, only Eth3 will work. As a workaround please establish the connection to the tool with the last Network Interface Controller (NIC) connected to the Open-E system or disable all except the first controller (disable Eth1, Eth2 and Eth3 to force Eth0 to function). It can be done with Open-E WebGUI under “Setup -> Network” administration panel.
