The Cisco C-SM-NIM-ADPT= is a single-wide Service Module (SM-X) carrier adapter designed exclusively for Cisco Catalyst 8300 Series Edge Platforms. It acts as a slot converter, allowing the installation of two (2) Network Interface Modules (NIMs) into a single SM-X slot. This adapter significantly expands the modular connectivity options and port density of the router, enabling seamless integration of high-speed WAN, LAN, and security modules without sacrificing performance.
Dual NIM Capacity: Converts one SM-X slot into two independent NIM slots.
Full Compatibility: Supports all Cisco Catalyst 8000 Series NIMs (e.g., C-NIM-1X, C-NIM-8T, C-NIM-2T).
Non-Blocking Performance: Equipped with two dedicated 10-Gbps backplane links, ensuring full wire-speed throughput for both NIMs simultaneously—even when populating both with 10G modules.
No Oversubscription: Eliminates performance bottlenecks, preserving the full feature set (including MACsec, QoS, and jumbo frames) of each installed NIM.
Maximizes Slot Utilization: Optimizes the use of valuable SM-X real estate, ideal for branches needing diverse WAN/LAN connections.
Mixed Media Support: Enables flexible combinations (e.g., one 10G fiber NIM + one 8-port copper GE NIM).
Hot-Swappable: Supports Online Insertion and Removal (OIR) for upgrades or replacements without powering down the router.
Scalable Deployment: Multiple adapters can be installed, limited only by the number of available SM-X slots on the chassis.
Plug-and-Play: Seamless integration with Cisco IOS XE; auto-detects and configures installed NIMs.
SD-WAN Ready: Fully manageable via Cisco vManage, supporting end-to-end SD-WAN policies.
Robust Environmental Specs: Designed for operation in demanding enterprise branch conditions.
