The Cisco GSR10-CSC is a critical switch fabric component. It is designed for the Cisco 12000 Series Gigabit Switch Routers (GSR).
This module functions as a Clock Scheduler Card (CSC). It provides system timing, synchronization, and scheduling for the router’s switch fabric.
In the Cisco 12410 router, the switch fabric requires two CSC modules:
- One active CSC for operation
- One standby CSC for redundancy
The GSR10-CSC is part of a high-capacity switching system. It supports up to 200 Gbps switching fabric bandwidth, ensuring efficient packet forwarding in core networks.
This card plays a key role in:
- Synchronizing data flow across line cards
- Managing traffic scheduling within the switch fabric
- Maintaining system stability and performance
The module is typically used in carrier-grade environments, including:
- ISP core networks
- Large enterprise backbone infrastructure
- High-capacity routing deployments
⚠️ Note: The Cisco 12000 series (including this module) is End-of-Life (EOL) and mainly available in refurbished markets today.
