The NXA-PAC-1100W-PE2 is a hot-swappable 1100W AC power supply unit designed for Cisco Nexus 9000 Series switches. It features Port-Side Exhaust (PE) airflow, making it ideal for data center environments that follow a front-to-back cooling layout.
As a second-generation version of the popular PE model, the PE2 offers improved power efficiency and reliability, delivering robust and consistent power in high-performance, mission-critical deployments. The PSU supports redundant configurations (N+1) and can be replaced on the fly, minimizing operational downtime.

A: It uses Port-Side Exhaust (PE) airflow, which pushes air from the network port side to the rear — perfect for front-to-back rack cooling.
Q2: How is PE2 different from the PE model?
A: The PE2 version is a second-generation PSU with improved reliability, efficiency, and broader compatibility with newer Cisco Nexus systems.
Q3: Is this power supply hot-swappable?
A: Yes, the NXA-PAC-1100W-PE2 is fully hot-swappable, allowing it to be replaced without powering down the device.
Q4: Can it be used in redundant power setups?
A: Yes, it supports N+1 redundancy, ensuring uninterrupted operation even if one PSU fails.
Q5: Which switches are compatible with this PSU?
A: It is commonly used in Cisco Nexus 9300 and 9500 Series switches. Check your specific model’s datasheet for exact compatibility.
