HPE R0X35A#ABA Aruba 6400 1800W Hot-Plug Power Supply with C16 Inlet
Overview
The HPE R0X35A#ABA is a 1800W hot-plug power supply module engineered for the HPE Aruba 6400 series modular switch chassis. Rated at 54V DC output and accepting AC or DC input through a C16 inlet adapter, this plug-in module slots directly into the Aruba 6405 and 6410 chassis without powering down the switch — a critical capability for any environment where network downtime carries real operational cost. At 4.1 in x 13 in x 1.6 in and 4.19 lbs, it occupies a single PSU bay in the chassis and supports the power demands of fully-loaded high-density port configurations including PoE-heavy line cards.
If you are commissioning or expanding an enterprise network switch deployment around the Aruba 6400 platform, R0X35AABA (the hyphen-stripped search variation) and R0X35A#ABA refer to the same unit — the hash is part of the localization suffix (#ABA = United States, English).
Key Features
- 1800W Power Capacity: The 6400 chassis supports dense line card configurations — 48-port SFP+ cards and 96-port PoE cards both draw heavily under load. At 1800W, this PSU provides the headroom those line cards need at full population without running the power subsystem at its ceiling, which degrades reliability over time.
- 54V DC Output Voltage: The Aruba 6400 platform uses a 54V internal power bus, matching the standard for high-efficiency PoE delivery to downstream ports. This voltage level is what makes the architecture efficient at scale — less conversion loss compared to lower-voltage designs.
- Hot-Plug Design: Replace or add a failed or additional PSU while the switch remains in service. For data centers and network closets running around the clock, this means a PSU swap does not require a maintenance window. Pull the failed unit, slide in the replacement, done — no impact to traffic forwarding.
- AC/DC Input Flexibility: Accepts both AC and DC input, which matters in facilities that have invested in DC plant infrastructure (common in telco, colocation, and some campus deployments). You are not locked into AC-only power delivery.
- C16 Inlet Adapter: The C16 (IEC 60320 C16) inlet is the correct connector for high-current AC feeds — it locks more securely than a standard C14 and is appropriate for the amperage this unit draws at full 1800W load. Verify your PDU or power strip has C15 or C17 outlets before ordering cables separately.
- Plug-In Module Format: Ships as a self-contained module — no tools required for installation into the chassis bay. The form factor (4.1 x 13 x 1.6 in) is chassis-specific; do not attempt to install this unit in non-6400-series enclosures.
- US Localization (#ABA): The #ABA suffix designates United States / English configuration. This matters for regulatory compliance and power inlet compatibility with North American PDU standards. Do not substitute a non-ABA variant in US deployments expecting to match inlet types without an adapter.
Integration & Compatibility
The R0X35A#ABA is designed and validated for the following HPE Aruba 6400 series chassis:
- HPE Aruba 6405 48SFP+ 8SFP56 — high-density fiber aggregation chassis
- HPE Aruba 6405 96G CL4 PoE 4SFP56 — 96-port PoE switch chassis where power budget is the binding constraint; the 1800W rating directly determines how many ports can deliver full PoE Class 4 simultaneously
- HPE Aruba 6405 Switch Bundle
- HPE Aruba 6410 — larger modular chassis requiring higher aggregate power for full slot population
- HPE Aruba 6410 Switch Bundle
For power supply planning on the 6400 platform, HPE recommends deploying PSUs in pairs for redundancy — the chassis supports N+1 power configurations. If one PSU fails, the remaining unit carries the full load. Size your total installed PSU capacity against worst-case line card power draw before commissioning. Consult the network infrastructure accessories section for compatible line cards, fan trays, and chassis components.
Frequently Asked Questions
Q: Which switch chassis is the R0X35A#ABA compatible with?
A: The R0X35A#ABA is validated for the HPE Aruba 6405 48SFP+ 8SFP56, 6405 96G CL4 PoE 4SFP56, 6405 Switch Bundle, 6410, and 6410 Switch Bundle chassis. It is not designed for other Aruba switch families.
Q: Can I replace the R0X35A#ABA while the switch is running?
A: Yes. This is a hot-plug module — it can be inserted or removed while the chassis is powered and forwarding traffic, provided at least one other PSU is installed and carrying the load.
Q: What inlet connector type does the R0X35A#ABA use?
A: It uses a C16 (IEC 60320 C16) inlet adapter. Your PDU or power source must provide a matching C15 or C17 outlet. Verify cable compatibility before deployment.
Q: What is the output voltage of the R0X35A#ABA?
A: The unit outputs 54V DC, matching the internal power bus specification of the HPE Aruba 6400 chassis platform.
Q: Does the R0X35A#ABA support DC input power?
A: Yes. The unit accepts both AC and DC input, making it suitable for facilities with DC plant infrastructure such as colocation environments and telco deployments.
Q: What is the warranty on the R0X35A#ABA?
A: HPE provides a manufacturer warranty on this product. Contact the seller or HPE directly for the specific warranty terms applicable to this SKU in your region.
The R0X35A#ABA is the right call when you are building out or expanding an HPE Aruba 6405 or 6410 chassis and need a genuine replacement or redundant PSU — specifically one that matches the 54V DC internal bus and the C16 inlet requirement. That 54V spec is not interchangeable; drop in the wrong voltage PSU and the chassis will not recognize it.
Technical Highlights:
- 1800W Output Capacity: On a fully-loaded 6405 96G CL4 PoE chassis with Class 4 PoE ports running near capacity, you need this wattage. Running short on PSU capacity means the chassis will start shedding PoE budget to protect itself — exactly what you do not want in a production environment.
- Hot-Plug Module: The plug-in module format means a PSU failure does not force a maintenance window. Swap the unit live, confirm the chassis picks up the new PSU, done. This is a practical operational advantage, not a checkbox feature.
- C16 Inlet Adapter: The C16 locking connector draws more securely than a C14 at the amperage levels this PSU operates at. Make sure your rack PDU has C15 outlets — a common mismatch that gets caught at installation time, not during the order process.
Deployment Considerations:
- Deploy in pairs for N+1 redundancy — the 6400 chassis supports this natively, and a single-PSU configuration is a single point of failure in any production switch deployment.
- The #ABA localization suffix is US/English-specific; the C16 inlet is sized for North American high-current feeds. Do not substitute a non-ABA variant expecting the inlet to match without an adapter.
This PSU is the right unit for enterprise campus and data center teams running Aruba 6405 or 6410 chassis who need a factory-new, chassis-validated replacement — particularly in PoE-dense deployments where operating below the 1800W ceiling matters for long-term reliability.
