Seamless integration with our existing fabric cards. The card's performance has been flawless, and it handles the complex scheduling of our 320G system easily.
The Enhanced Clock Scheduler Card (12416E-CSC) is an OEM timing module for Cisco 12416 routers that delivers high-precision clocking, advanced scheduling, and improved network synchronization.
The 12416E-CSC card is fully compatible with Cisco 12416 Series routers and is backward-compatible with Cisco 12000 Series chassis that support enhanced clock modules.
Power down your Cisco 12416 router, slide the 12416E-CSC into the designated clock module slot, secure the retention screws, then power up and verify module recognition via the router CLI.
This card offers sub-microsecond synchronization accuracy, reduced packet jitter, and optimized traffic scheduling, resulting in lower latency and higher overall network reliability.
No, the Enhanced Clock Scheduler Card must be installed or removed only when the router is powered down to ensure hardware integrity and prevent configuration loss.
Use the show controllers timing command in privileged EXEC mode to confirm the card status, synchronization source, and clock accuracy readings.
The card supports IEEE 1588v2 Precision Time Protocol (PTP), Synchronous Ethernet (SyncE), and Network Timing Protocol (NTP) for diverse synchronization environments.
Key benefits include superior clock stability, precise traffic scheduling, simplified network management, and reduced risk of packet loss in time-sensitive applications.
Ensure your Cisco IOS Software release meets the minimum version specified in the product release notes; a software upgrade may be required for full feature support.
Lead times vary by region and stock availability; most customers receive the module within 3–5 business days after order confirmation.
The 12416E-CSC card carries a standard one-year limited hardware warranty against defects in materials and workmanship, with extended coverage options available.
Verify cable connections, inspect the card status via CLI, confirm protocol settings (PTP, SyncE, NTP), and review log messages for error indications.
Yes, the card supports redundant clock sources and can be deployed in dual-slot configurations to ensure continuous synchronization in HA environments.
The 12416E-CSC draws less than 10W from the router backplane and operates within the Cisco 12416 chassis power specifications without additional power modules.
