System Specifications

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. Two side-by-side NME slots can be combined to accommodate one double-wide network module (NMD) or when available, a double-wide enhanced extended network module (NME-XD).
