About the Cisco NXA-PAC-1100W-B Cisco power supply / PSU
Remote monitoring via SNMP/Modbus/USB is table-stakes for modern data centre power infrastructure, and the Cisco NXA-PAC-1100W-B delivers enterprise-grade reliability in a hot-swappable modular form factor. This genuine Cisco AC Power Supply Unit is purpose-built for the Cisco Nexus 9000 Series, specifically the Nexus 9300 and 9500 platforms, and provides 1100 W of output power with universal input support from 100–240 V AC at 50/60 Hz. The proprietary Cisco chassis backplane connector and port-side exhaust airflow design (B-side) ensure seamless integration into existing Nexus deployments without thermal or mechanical compromise.
Network engineers and IT procurement teams selecting redundant power architecture will benefit from this unit's native support for N+1 and 1+1 power redundancy configurations, combined with its hot-swap capability for zero-downtime maintenance. Full compliance with UL, CE, and RoHS standards, paired with genuine Cisco designation, unlocks immediate eligibility for Cisco SMARTnet and TAC support engagement—a critical requirement for mission-critical fabric environments. The NXA-PAC-1100W-B (part number NXA-PAC-1100W-B) is the only supported genuine Cisco PSU for these platforms and delivers the warranty, diagnostics, and vendor accountability that enterprise deployments demand.
Platform Compatibility & Redundancy Use Cases
- Nexus 9300 and 9500 fabric refresh with N+1 redundancy for zero single-points-of-failure in core switching
- Multi-chassis deployments requiring synchronized power delivery and hot-swap field replacement
- Data centre environments mandating genuine Cisco components for TAC support coverage and warranty protection
- High-availability leaf-spine architectures where modular PSU swaps must occur without fabric disruption
- Standardized power infrastructure reducing spare inventory complexity across Nexus 9000 generations
