Cisco NXA-PAC-1100W-PE Full English Description

The Cisco NXA-PAC-1100W-PE is a hot-swappable 1100W AC Field-Replaceable Unit (FRU) power supply designed for Cisco Nexus 9000 Series fixed form-factor data center switches. It adoptsPort-Side Exhaust (Forward Airflow)design identifiable by the blue handle label, conforming to NEBS standards and delivering 80 PLUS Platinum high efficiency. This power module supplies stable 12VDC power for high-performance leaf-spine switching hardware, supporting redundant deployment to guarantee high availability for ACI fabric, enterprise and colocation data center infrastructures.

1100 Watt Continuous Rated Output

Delivers up to 1100W 12VDC power output. Supports 1+1 redundant configuration and dynamic load sharing, eliminating single-point power failure for mission-critical data center network environments.
Universal Auto-Ranging AC Input

Wide voltage input applicable to global data center power grids:

Low line: 90 VAC ~ 132 VAC
High line: 180 VAC ~ 264 VAC
Operating frequency: 47 Hz ~ 63 Hz (nominal 50/60Hz)
Input connector: Standard IEC C13 power inlet

Port-Side Exhaust (Forward Airflow)

Air flows into the switch from fabric side and exhausts outward from port side.

Important Note: All power supplies and fan trays installed within the same chassis must use identical airflow direction. Never mix PE (port-side exhaust) and PI (port-side intake) modules inside one switch.
Hot-Swap FRU Architecture

Supports online insertion and removal. Technicians can replace defective power modules without powering off the host switch, enabling non-disruptive hardware maintenance.
Real-Time Telemetry & LED Status Indication

Front-panel LED indicators visually display AC input status and operational health. The module transmits temperature, voltage and fault alarm data to the switch operating system via chassis backplane.
Multi-Layer Hardware Protection

Built-in overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short-circuit protection to safeguard both the power supply and host switch hardware.
80 PLUS Platinum High Efficiency

High-efficiency power conversion minimizes energy loss and heat emission, reducing overall cooling expenditure in large-scale data center facilities.
