I don't think a /8 netmask will work, you should use /24
(netmask 255.255.255.0)

Ip range 10.n.n.n uses /8 netmask normally, can be set to /16 or/24 to isolate intra networks.
But the netmasks are in the following format:
255.0.0.0 = /8
255.255.0.0 = /16
255.255.255.0 = /24
While broadcasts are:
10.255.255.255
10.10.255.255
10.10.10.255

After writing the IP address the netmask gets set automatically to 8.
P.S.
Sorry for double posting but editing takes a while.

Fixed the netmask in my reply
but still think /24 netmask is needed
(Need to check the 7I92s netmask logic)

If it helps, almost all my machines use 7i92 and all use the /8 netmask, never had a single issue.
Even the big Hurco uses 7i92 and same IP setup.
Oh goodie, found a PDF :

At some point the 7I92s netmask got changed from fixed
to EEPROM based. I need to check what this is set to.

OP:

Is the situation still the same? That is, what does:

mesaflash --device 7i92 --addr 10.10.10.10 --readhmid

report?

I always use an 8 bit mask now with a 10.0.0.0 network,  but I do remember having issues with one of the mesa cards and when I set it to a 24 bit mask it worked.


/edit subnetting makes my head hurt so I don't do it anymore....lol
