Cisco Nexus 3550-H Hydra Layer 1 SW Subscription N35-H-SW-3Y — 3 Year | Nexus, Layer 1 — N35-H-SW-3Y

Ensure uninterrupted Layer 1 capabilities on Nexus 3550-H systems with the N35-H-SW-3Y 3 Year software subscription. This license preserves Hydra Layer 1 feature entitlements and authorized software upgrades for Nexus 3550-H devices, allowing your switching fabric and physical connectivity controls to remain consistent across the lifecycle. Use this subscription to maintain firmware-level features that impact port behavior, diagnostics, and other low-level functions critical to deterministic designs. For infrastructure teams managing top-of-rack or leaf deployments that depend on precise physical-layer behavior, a multi-year subscription reduces the operational risk that comes from expired feature entitlements. The three-year term aligns with common refresh and maintenance cycles, giving procurement teams a predictable renewal window and minimizing unexpected changes to device capabilities. Choose this SKU when you require continued Layer 1 feature support and sanctioned software updates on Nexus 3550-H hardware for an extended term. Ideal For Preserve physical-layer features for leaf/top-of-rack Nexus 3550-H deployments Maintain firmware entitlements for deterministic data center fabrics Align long-term support for high-availability aggregation switches Standardize extended license renewals across multi-site Nexus estates Why This Product 1 Provides three-year continuity for Layer 1 Hydra features versus short-term renewals 2 Targets Nexus 3550-H devices specifically, unlike generic Nexus bundles 3 Focuses on physical-layer entitlements rather than broader management suites 4 Aligns long-term support windows with common refresh cycles for aggregation switches
