Questions & Answers
What is the Cisco N9K-SC-A system controller for Nexus 9500?
The N9K-SC-A is Cisco’s system controller module that manages control-plane functions for Nexus 9500 series switches, providing centralized management, high availability, and orchestration of fabric resources.
Which Nexus 9500 chassis models support the N9K-SC-A?
The N9K-SC-A is compatible with Cisco Nexus 9504, 9508, and 9516 chassis. Ensure your chassis is a fixed configuration from the Nexus 9500 series.
What are the key features of the N9K-SC-A system controller?
Key features include centralized control-plane management, stateful control-plane failover, multi-instance FabricPath routing, advanced telemetry, and programmable workflow integration via NX-OS APIs.
How does the N9K-SC-A improve network availability?
It supports dual redundant controllers with hot-standby failover, stateful control-plane synchronization, and non-disruptive software upgrades, ensuring continuous fabric operation.
What power requirements does the N9K-SC-A have?
The module requires a single 450W slot power draw. Actual consumption depends on enabled features; ensure the chassis has adequate power-supply capacity for peak operation.
Is the N9K-SC-A hot-swappable?
Yes. You can install or replace the N9K-SC-A module without powering down the Nexus 9500 chassis, preserving fabric forwarding during maintenance.
Which NX-OS release is required for N9K-SC-A?
Cisco NX-OS version 7.0(3)I1(1) or later is required. Always verify the Cisco Software Compatibility Matrix for the specific feature sets you plan to deploy.
How do I install the N9K-SC-A in my chassis?
Slide the controller into the designated supervisor bay until it latches. Connect management and fabric cables as documented. Verify module status via the ‘show module’ NX-OS command.
How can I monitor the performance of the system controller?
Use NX-OS CLI commands like ‘show system internal’ or integrate with Cisco Prime or DCNM for real-time telemetry, resource utilization metrics, and health dashboards.
What redundancy options are available with N9K-SC-A?
Deploy two N9K-SC-A modules for active-standby controller redundancy. The modules synchronize control-plane state to deliver seamless failover and uninterrupted management.
Does the N9K-SC-A require a software license?
Basic control-plane functionality is included. Advanced features such as FabricPath and enhanced telemetry may require appropriate Cisco NX-OS feature licenses or Smart Licensing.
How many FabricPath instances can N9K-SC-A support?
The module supports up to 16 FabricPath virtual networks, enabling scalable multi-tenant or segmented fabric designs in large campus and data center deployments.
What warranty and support options are offered for N9K-SC-A?
Cisco provides a limited lifetime hardware warranty with 90-day software support. Extended service options, such as Cisco SMARTnet, are available for faster RMA and 24x7 assistance.
