FAQs

Q: What chassis models support the N9K-X9432PQ line card?
A: The N9K-X9432PQ is compatible with Cisco Nexus 9500 series chassis including the 4-slot (9504), 8-slot (9508), and 16-slot (9516) models. It requires NX-OS operating mode and is not compatible with ACI mode deployments.

Q: Can the 40G QSFP+ ports be broken out to 10G?
A: Yes, each 40 Gigabit Ethernet QSFP+ port supports 4x 10 Gigabit Ethernet breakout using appropriate breakout cables and optics, making this line card suitable for both 40G aggregation and high-density 10G access layer deployments.

Q: How many fabric modules are required for full performance?
A: The N9K-X9432PQ requires 4 fabric modules (N9K-C9504-FM, N9K-C9508-FM, or N9K-C9516-FM depending on chassis) to achieve the full 2.56 Tbps switching capacity and maximum bandwidth performance.

Q: What is the typical use case for this line card?
A: This line card is designed for data centre aggregation layer deployments, providing high-density 40G connectivity for top-of-rack switch uplinks or 10G server access via breakout cables. It supports VXLAN overlay protocols for modern software-defined networking architectures.

Q: Is the line card hot-swappable?
A: Yes, the N9K-X9432PQ is hot-swappable and features auto-discovery upon insertion, allowing for non-disruptive installation and replacement in operational Nexus 9500 chassis without requiring system downtime.
