Network-module slots: These slots can accommodate a standard
network module, enhanced network module (NME), enhanced
extended network module (NME-X), and high-density extension
module (EVM-HD). The NME-X, when available, will have a wider form
factor than the NME. You can combine two side-by-side NME slots to
accommodate one double-wide network module (NMD) or when
available, a double-wide enhanced extended network module (NME-
XD).
