FUJITSU ServerView Virtual-IO Manager V3.1 - Manual (Page 81)

Validity of MAC address input is not checked. Please advance to the
next screen after confirming your input address is valid.
The validity of the MAC address input is not checked. Please
confirm that your input address is valid before you click Next.
If you have several installations of the Virtual-IO Manager in
your LAN network, then you must ensure that the address
ranges used do not overlap. Otherwise addresses may be
assigned several times.
To change the range of the address after installation is finished,
you must uninstall the Virtual-IO Manager and install it again.
Therefore, if it is possible that addresses may have to be added
after the Virtual-IO Manager is set up, we recommend that you
install it without selecting the address range. You should input a
virtual address when creating the server profile.
