HPE R0X36A#ABA Aruba 6400 3000W Plug-In Power Supply Module
Overview
The R0X36A#ABA is a 3000W hot-swap power supply designed specifically for the HPE Aruba 6400 modular switch chassis. It accepts both 120V and 230V AC input through a C20 inlet and delivers a regulated 54V DC output — the rail the Aruba 6400 line-cards and PoE subsystems draw from. If you're commissioning a high-density 6400 chassis or replacing a failed unit in an existing deployment, the R0X36A#ABA is the correct supply for that platform.
At 3000W output in a 1.6 × 4.1 × 13-inch plug-in module form factor, this supply is sized for fully loaded 6400 configurations running PoE++ ports at scale. The plug-in module format means it installs and removes without powering down the chassis — a practical requirement in any environment where switch downtime is measured in revenue, not inconvenience.
Key Features
- 3000W Output Capacity: A 3000W supply gives the Aruba 6400 chassis enough headroom to power a fully populated line-card configuration including high-draw PoE++ ports. Running a single undersized supply at the edge of its rating shortens its service life; this unit keeps you well inside the comfort zone on loaded deployments.
- Dual-Voltage AC Input (120V / 230V): Auto-ranging AC input across 120V and 230V means the same SKU works in North American and international data center environments without an adapter or a separate regional SKU. Useful for organizations provisioning globally standardized spares inventory.
- 54V DC Output Rail: The Aruba 6400 platform is designed around a 54V DC distribution architecture. This supply delivers that rail directly — mismatched supply voltage is a common cause of field compatibility failures, and the R0X36A#ABA eliminates that risk by being purpose-built for the 6400 chassis.
- C20 Inlet: The IEC C20 inlet is the correct mating connector for C19 PDU outlets — the standard outlet type on rack-mounted power distribution units in enterprise and colocation data centers. No adapter required when connecting to a properly specified PDU.
- Plug-In Module Form Factor: The plug-in module design allows installation and removal from a live chassis. In a dual-supply 6400 configuration, this enables supply replacement without a maintenance window — the surviving supply carries load while the failed unit is swapped.
- RoHS Compliant: RoHS compliance matters for government, education, and EU-market deployments where environmental compliance documentation is part of the procurement process. The R0X36A#ABA carries this designation from the factory.
- Compact Physical Footprint: At 1.6 in high × 4.1 in wide × 13 in deep and 4.41 lb, the supply slots into the 6400 chassis bay without occupying adjacent rack space. The depth of 13 inches is compatible with standard 4-post rack configurations.
Integration and Compatibility
The R0X36A#ABA is designed exclusively for the HPE Aruba 6400 switch chassis family. Before ordering, confirm the 6400 chassis model and the number of supply bays available — the 6400 supports multiple power supply configurations depending on chassis SKU, and deploying the correct quantity of supplies for N+1 redundancy requires knowing the chassis's rated power budget against your actual port and PoE load.
Pair this supply with a C19-outlet PDU in your rack to match the C20 inlet without adapters. For high-availability configurations, deploy a second R0X36A#ABA in the redundant supply bay. The 54V DC architecture means supplies load-share when both are installed, distributing thermal stress across both units rather than running one at full capacity.
If you're building or expanding an Aruba 6400 deployment and need guidance on power budgeting across line-cards and PoE loads, consult the Aruba 6400 platform power configuration guide available from HPE's support portal. Chassis power budget calculations depend on specific line-card combinations and PoE class mix — do not assume a single 3000W supply is sufficient without running the numbers for your specific configuration.

Frequently Asked Questions
Q: What chassis is the R0X36A#ABA compatible with?
A: The R0X36A#ABA is designed for the HPE Aruba 6400 modular switch chassis. It is not a universal power supply — verify your specific 6400 chassis SKU against HPE's compatibility matrix before ordering.
Q: Does the R0X36A#ABA support hot-swap replacement?
A: The plug-in module form factor supports hot-swap installation and removal in a dual-supply chassis configuration. A second supply must be installed and carrying load before removing the R0X36A#ABA to avoid a chassis power interruption.
Q: What PDU outlet type does the C20 inlet require?
A: The C20 inlet mates with a C19 outlet. Ensure your rack PDU has available C19 outlets rated for the supply's draw before installation. Standard enterprise PDUs in 20A and 30A configurations typically include C19 outlets for high-draw devices.
Q: Will this supply work in a 120V data center environment?
A: Yes. The R0X36A#ABA auto-ranges across 120V and 230V AC input, so it operates in both North American (120V) and international (230V) facility power environments without modification.
Q: Is the R0X36A#ABA RoHS compliant?
A: Yes. The R0X36A#ABA carries RoHS environmental compliance, which satisfies the documentation requirements for government, education, and EU-market procurement processes.
Q: What is the output voltage of the R0X36A#ABA?
A: The supply delivers 54V DC output — the correct rail for the Aruba 6400 chassis architecture. Do not substitute supplies with different output voltage ratings, as the 6400 platform is designed for 54V DC distribution.
The R0X36A#ABA is a straightforward procurement decision once you confirm chassis compatibility, but it's a decision that deserves attention to detail. At 3000W output on a 54V DC rail, this supply is sized for high-density Aruba 6400 deployments where you're running PoE++ ports at scale — and at that load level, a supply sourced incorrectly or installed without a redundant partner is a single point of failure in critical infrastructure.
Technical Highlights:
- 3000W Output Headroom: Running a 6400 chassis with a full complement of PoE++ line-cards can push per-supply draw well above 1500W; the 3000W rating on this unit provides real operating margin, not just peak rating compliance.
- Auto-Ranging 120V/230V Input: A single SKU that spans both North American and international input voltage means your spares inventory doesn't need to be regionally segregated — a meaningful operational simplification for multi-site enterprises.
- C20 Inlet / 54V DC Architecture: The C20 inlet mates directly with C19 PDU outlets standard in enterprise rack environments; the 54V DC output rail is the exact specification the Aruba 6400 chassis expects — two details that matter for a clean, adapter-free installation.
Deployment Considerations:
- Always install the R0X36A#ABA in a dual-supply configuration for any production chassis — the plug-in module format enables hot-swap, but hot-swap is only safe when a second supply is already online and load-sharing.
- The 13-inch depth fits standard 4-post rack configurations, but verify your chassis bay clearance and PDU positioning before installation; a C19 outlet on a rear-mounted PDU needs to reach the C20 inlet without cable stress.
This supply is the right specification for a fully loaded Aruba 6400 chassis in a campus core or data center distribution role where PoE++ port density drives power budget requirements above what lower-wattage supply options can cover.
