• Supports IEEE 1588 Precision Time Protocol (PTP) and Synchronous Ethernet (SyncE)
• Hot-swap capable for zero-downtime installation
• Backward compatible with existing Catalyst 8540 chassis and software releases
• Low power consumption and reduced heat output

Technical Specifications

• Model/Part Number: UPG-MSR-MRP-3CL
• Form factor: 3U rack-mountable module
• Input voltage: 100 to 240 V AC, 50/60 Hz
• Power draw: max 45 W
• Operating temperature: 0 to 40 degrees C (32 to 104 degrees F)
• Storage temperature: -40 to 70 degrees C
• Interface: Dual 1000BASE-X SFP ports for clock distribution
• Supported protocols: PTP v1/v2, SyncE, NTP
• Compliance: FCC, CE, RoHS

Applications

This clock upgrade is ideal for service providers and large enterprises that require reliable time synchronization across transport networks, data centers, and carrier Ethernet environments. Typical use cases include:

• Carrier Ethernet synchronization for video and voice services
• Metro Ethernet aggregation with strict latency requirements
• Multi-region protection schemes where timing redundancy is critical
• Network timing for financial trading platforms and industrial automation
• Integration with SDN controllers that rely on precise clock information

By installing the Cisco Catalyst 8540 MSR-MRP SRATUM 3 Clock Upgrade, organizations can achieve tighter network timing, improve service quality, and future-proof their infrastructure against evolving synchronization standards.
