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
Maximum Number of NMD/NME-XDs Supported
Maximum Number of EVM-HDs Supported
Number of HWIC Slots (These HWIC slots also support
voice interface cards (VICs), voice/WAN interface cards
(VWICs), and WICs)
