Introduction to Cisco Network Module Form Factors
Cisco network modules are available in the following four different form factors to provide greater
modularity and functionality for users:
•
Single-wide network modules, also called NM or NME (see
Figure 1-1
)
•
Extended single-wide network modules, also called NME-X (see
Figure 1-2
)
•
Double-wide network modules, also called NMD (see
Figure 1-3
)
•
Extended double-wide network modules, also called NME-XD (see
Figure 1-4
)
Single-wide network modules are installed in fixed network module slots on Cisco 2600 series,
Cisco 3600 series, Cisco 3700 series, and Cisco MWR 1941-DC routers, and in configurable network
module slots on Cisco 2811, Cisco 2821, Cisco 2851, and Cisco 3800 series routers. See
Figure 1-1
for
a sample single-wide network module.
