standard network module, NME, and NME-X slots.
The NME has the same form factor as the standard
network module. The EVM-HD is supported. The
NME-X, when available, will have a wider form factor
than the NME. Two side-by-side NME slots can
be combined to accommodate one NMD or, when
available, a NME-XD.)
Maximum Number of Network Modules, NMEs, and
NME-Xs Supported
