Cisco DS-13SLT-FAB1 MDS 9513 Fabric Clock Module

Overview
The Cisco MDS 9513 Fabric Clock Module (DS-13SLT-FAB1) provides precise timing synchronization for Cisco MDS 9513 and compatible storage area network (SAN) switches. Designed for high-performance data centre environments, this module ensures that all fabric components operate with a common clock reference, reducing latency and improving overall network stability.

Key Features

• High accuracy clock source for SAN fabrics
• Supports both internal and external timing references
• Hot-swap capable for non-disruptive maintenance
• Compact form factor that fits into standard MDS 9513 chassis slots
• LED status indicator for quick health monitoring

Technical Specifications

• Model/Part Number: DS-13SLT-FAB1
• Compatibility: Cisco MDS 9513, MDS 9148, MDS 9148S, and other supported MDS platforms
• Clock type: Synchronous Ethernet (SyncE) and IEEE 1588 Precision Time Protocol (PTP) support
• Input frequency range: 1 Hz to 10 MHz
• Output frequency: 125 Hz (default) with configurable options
• Power consumption: less than 5 watts
• Operating temperature: 0 to 40 degrees Celsius
• Dimensions: 1U height, fits standard rack mounting

Applications

• Enterprise data centre SAN deployments that require tight timing coordination
• High-performance computing clusters where synchronized data transfers are critical
• Telecom and service provider networks that use Fibre Channel over Ethernet (FCoE) with strict timing requirements
• Disaster recovery sites that need consistent clock alignment across geographically dispersed fabrics
• Any environment that benefits from reduced packet loss and improved deterministic behavior in storage traffic

By integrating the Cisco MDS 9513 Fabric Clock Module, organizations can achieve reliable timing, simplify network management, and maintain optimal performance across their SAN infrastructure.
