The Cisco ISR4221-SEC/K9 is a powerful router designed for high-performance networking. One of the key features of this device is its ability to support expansion modules through the use of Enhanced High-Speed WAN Interface Cards (EHWIC) and Network Interface Modules (NIM).

No DIMM Expansion

Unfortunately, the Cisco ISR4221-SEC/K9 does not have a DIMM (Dual In-Line Memory Module) slot for memory expansion. This means that the router's memory capacity is fixed and cannot be increased through the use of additional modules.

EHWIC Options

On the other hand, the Cisco ISR4221-SEC/K9 does support EHWIC modules, which provide enhanced WAN interface capabilities. These modules can be used to increase the router's WAN bandwidth and support high-speed networking applications.

NIM Options

In addition to EHWIC modules, the Cisco ISR4221-SEC/K9 also supports NIM modules, which provide advanced network services and features. These modules can be used to enhance the router's performance and capabilities in a variety of networking environments.

Cisco ASR and 1000 Series Compatibility

The Cisco ISR4221-SEC/K9 is compatible with the Cisco ASR series and 1000 series routers. This means that users can easily integrate the router into their existing network infrastructure and take advantage of advanced features and services.
