HCI-PSU-6600-AC Overview
A server power supply unit (PSU) is the power conversion stage of the power management hierarchy in data center hardware: it converts utility AC input into the regulated DC rails that feed server motherboards, fabric interconnects, and compute nodes. Hot-plug redundant PSUs such as this module allow replacement without powering down the host, which is the foundation of high-availability server architectures.
Key features of the HCI-PSU-6600-AC include a 1400 W (1.4 kW) continuous output rating, dual-range AC input supporting both 120 V AC and 230 V AC utility feeds, hot-plug and redundant operation for zero-downtime maintenance, and a port-side exhaust airflow scheme that matches the cooling architecture of Cisco UCS 6600 Series chassis. Distributor listings also classify the 6600 family as 80 PLUS Platinum efficiency class, reducing wasted heat and operating cost in dense racks.
Technically, the module integrates AC-to-DC conversion, active power factor correction, output regulation, and status LED indication in a single field-replaceable unit. According to the Cisco UCS 6600 Series Fabric Interconnect Installation and Service Guide, each 1400W port-side exhaust AC power supply module (UCS-PSU-6600-AC) has a status LED providing visual indication of operational and performance state, simplifying fault isolation in production environments.
Typical applications include powering Cisco UCS 6600 Series Fabric Interconnects that form the management and communication backbone for UCS X-Series compute nodes, the UCS X9508 Chassis, B-Series blade servers, and C-Series rack servers, as well as hyperconverged infrastructure (HCI) deployments - the origin of the HCI prefix in this MPN.
When designing or maintaining systems with this PSU, verify airflow direction compatibility: port-side exhaust modules must not be mixed with port-side intake modules in the same chassis, as mismatched airflow disrupts the thermal design.

Typical Applications
HCI-PSU-6600-AC is suitable for 6 applications: Cisco UCS 6600 Fabric Interconnect Power, Hyperconverged Infrastructure (HCI) Rack Servers, Data Center Redundant Power (N+1) Configurations, UCS X-Series and Blade Backend Fabric, Enterprise Spares Inventory and Field Service, Global 120V/230V Mixed-Voltage Data Centers.
Cisco UCS 6600 Fabric Interconnect Power
The HCI-PSU-6600-AC is the designated 1400 W port-side exhaust AC power supply for Cisco UCS 6600 Series Fabric Interconnects, which form the management and communication backbone of the Cisco Unified Computing System. Its hot-plug redundant architecture allows a failed module to be swapped while the fabric interconnect continues forwarding traffic, protecting the control plane for X-Series compute nodes, the X9508 Chassis, and B-Series blades downstream. The dual 120/230 V AC input supports deployment in any global data center, and the blue color coding plus status LED simplify correct installation and fault identification during maintenance windows.
Recommended
Hyperconverged Infrastructure (HCI) Rack Servers
The HCI prefix in HCI-PSU-6600-AC denotes allocation to Cisco Hyperconverged Infrastructure builds based on UCS C-Series rack servers. HCI nodes concentrate compute, storage, and network virtualization on a single server, so power supply failure directly impacts storage cluster quorum and workload availability. The 1400 W rating covers the elevated power draw of dense NVMe and GPU-assisted HCI nodes, while hot-plug redundancy permits live replacement. Using matched port-side exhaust modules keeps the chassis thermal design intact, which is critical because HCI nodes typically run at higher sustained utilization than general-purpose servers, increasing heat load per rack unit.
Recommended
Data Center Redundant Power (N+1) Configurations
In N+1 power designs, the HCI-PSU-6600-AC operates as one of several parallel modules sharing the load, so any single module can fail or be removed without interrupting the server. The 120/230 V AC dual input lets each PSU connect to independent power domains or UPS branches, achieving A/B feed redundancy at the module level. The status LED gives operators immediate visual confirmation of module health during rack walk-throughs, and hot-plug capability means the failed unit is replaced with zero downtime. This is the standard high-availability pattern for production UCS deployments per Cisco's UCS 6600 installation documentation.
Recommended
UCS X-Series and Blade Backend Fabric
Cisco UCS 6600 Series Fabric Interconnects - powered by 1400W PSU-6600-AC-class modules - provide the management and communication backbone for UCS X-Series compute nodes, the UCS X9508 Chassis, and B-Series blade servers per the January 2026 Cisco data sheet. In this role the PSU protects not one server but the entire downstream compute estate: a fabric interconnect power failure would sever connectivity for thousands of blades and X-Series nodes. Specifying genuine 1400 W port-side exhaust modules with N+1 redundancy is therefore a fabric-level availability requirement, not merely a server-level one.
Recommended
Enterprise Spares Inventory and Field Service
Enterprise data center teams keep HCI-PSU-6600-AC / UCS-PSU-6600-AC modules as cold or warm spares for field replacement. Because lifecycle dates track the parent UCS C-Series and 6600 platforms (per eol.network), procurement teams should size the spares pool against the platform's remaining support window. The module's hot-plug nature means a trained technician can complete replacement in minutes without scheduling downtime, and the status LED verifies the new module is healthy before the maintenance window closes. Channel flexibility matters here: the same-spec UCS- numbered part is stocked more broadly than the HCI- variant.
Recommended
Global 120V/230V Mixed-Voltage Data Centers
Organizations operating data centers across regions with differing utility voltages benefit from the dual 120 V AC / 230 V AC input of the HCI-PSU-6600-AC: one spares SKU serves North American 120 V sites and international 230 V sites, simplifying logistics and reducing inventory duplication. Distributor listings (Ingram Micro, PC-Canada, Cendirect) explicitly document the dual input range at the 1400 W (1.4 kW) rating. When deploying at 120 V in high-load configurations, verify any input-voltage derating in official Cisco documentation and ensure branch circuits and power cords are rated for the actual continuous current draw.

Key Differentiators
- Zero-downtime hot-plug replacement (vs Fixed (non-hot-plug) server power supplies)
- Dual-range AC input for global fleets (vs Single-region 1400 W server PSUs)
- Airflow-coded thermal integration (vs Generic 1400 W ATX PSUs)
Design Notes
Never mix airflow directions in one chassis. The HCI-PSU-6600-AC is a port-side exhaust (blue) module; Cisco also ships port-side intake variants in other families (e.g., port-inlet spares). Installing an intake module into an exhaust-designed chassis reverses the thermal path, causing localized overheating and potential forced shutdown. Verify the color code and airflow arrow on the module handle before insertion, and audit all PSU slots after any third-party or multi-site sparing event.
Plan branch circuits for the actual continuous draw, not just the 1400 W nameplate. At 230 V AC the module draws roughly 6-7 A at full load (estimated: 1400 W divided by 230 V, ignoring efficiency margin); at 120 V AC this roughly doubles, so confirm cord ratings and PDU branch capacity, and check official Cisco documentation for any output derating at 120 V input before running the PSU near full load in North American deployments.
Lifecycle planning: per eol.network, component dates for HCI-PSU-6600-AC track the parent UCS C-Series / 6600 platform - spares retire when the platform retires. If your refresh cycle extends beyond the platform's announced last-support date, stock sufficient same-spec UCS-PSU-6600-AC spares now, since channel availability of the HCI- variant is narrower than the UCS- variant.
