Using new Myrinet NICs with old M3-E32/M3-SW18-8F switch

Hi,

I have an old cluster: each node with M3F-PCI64B-2
Myricom NIC connected via M3-E32/M3-SW18-8F switch. I
have unused slots in the switch that I would like to
use to integrate new nodes to the existing Myrinet
network.=20

Can I use newest Myricom cards such as M3F-PCIXD-2,
M3F-PCIXF-2, M3F-PCIXE-2 in the old Myrinet
environment, that is mixing old and new card in the
network managed by M3-E32/M3-SW18-8F switch?
