E-T-A -48VDC Power Distribution Infrastructure for HPE Equipment QuickSpecs
E-T-A Breaker Panels are designed for power distribution cabinet and IT equipment rack installation. Each breaker panel is designed for redundant and independent 2 x 8 DC power outputs in groups A and B, total 16 individual outputs per panel. One HPE G2H95A product contains two breaker panels, providing 32 individual or 16 redundant power outputs.

Removable one-piece front plate provides access to circuit breakers, which are plug-in type hydraulic-magnetic devices rated from 0.1A to 80A. Breakers available with HPE product numbers are from 6 amps to 80 amps. Unused circuit breaker slots in the front plate to be covered with included plastic covers. Plastic snap-in label holder for individual marking attached below circuit breakers. Each Breaker Panel is delivered with 24 blank labels.
Input (supply) terminals are labeled A+/A- and B+/B-. Output terminals are labeled A1+/A1- … A8+/A8- and B1+/B1- … B8+/B8-, with corresponding circuit breaker numbering in front. All cables connect to the rear of the unit, with screw type terminal block connectors for inputs and outputs as shown below.
Negative pole protected, positive pole grounded solution. M8 grounding bolts for each group on the right and left side panels. Internal grounding bridge providing option for positive supply pole to earth connection when used. Units are delivered with grounding bridge disconnected (see the “ground jumper” in above the internal wiring diagram).
Integrated group signaling for each supply group. Connection through 3-pole Phoenix connectors located in the rear section of the unit.
Installation depth 310 mm (including cable strain relief). Top and bottom covers made of perforated sheet metal for enhanced air circulation. Circuit breaker removal tool located on the PDU’s front panel reverse side.
Notes: Circuit breakers are not included in breaker panel kit, they have to be selected depending on the electrical load connected to each breaker panel output. Circuit breaker size recommendations provided with later on in this document.
For -48V DC power distribution, the following elements are required:
- – DC Breaker Panels, serving the same function as PDUs in AC setups – power distribution. Additionally, breaker panels host all circuit breakers protecting each output and device connected to it.
- – Circuit Breakers to be inserted into Breaker Panels, rating to be selected according to the load connected to each output.
- – Matching power cables, ideally in
- – optimal length to avoid excess as DC cables are thicker and excess consumes more space than on AC side. Best cable length depends on rack position of the breaker panel and the device connected to it
- – Grounding cables to connect the rack to the breaker panels grounding points
- – Grounding bar where all rack equipment are grounded, and which is connected to Data Center ground by local electrician
Hewlett Packard Enterprise has two different DC power distribution solutions, which do not share the same components. Either use all HPE DC power distribution components, or use the E-T-A partner products, but do not mix the two. The main difference is that E-T-A portfolio is richer, covers more deployment scenarios, and can be delivered pre-integrated in racks via Factory Express services.
Form Factor
- – E-T-A breaker panels are 2U form factor rack mounted DC power distribution units.
- – HPE product G2H95A contains two 19”, 2U power distribution units, total rack space consumed 4U

E-T-A power distribution components are compatible with select HPE equipment equipped with -48VDC power supplies. Please note that E-T-A cables cannot be used with HPE BladeSystem Breaker Panel (AH355A) and vice versa, as HPE DC power cables are not compatible with E-T-A breaker panel, because breaker panel side connectors are physically different between the two breaker panel types.
Factory integration of complete racks of DC powered equipment is only available with E-T-A DC components.
Step 1: Select required number of Breaker Panel kits
One Breaker Panel kit (G2H95A) contains two breaker panels and provides redundant 48V DC power for up to 16 dual power supply devices (total 32 individual DC outputs). Each breaker panel has 16 outputs arranged in two independent blocks of eight outputs for redundancy. Each block of 8 outputs has 3x85 amps high power outputs and 5x30 amps outputs. Those 85 amps outputs can be used to feed high power PSUs used in c7000 BladeSystem enclosures and Synergy frames, but can be used for smaller loads also in case no Synergy or c7000 enclosures connected.
While E-T-A components (excluding circuit breakers) are “sets” so that generally one set is enough for one device (examples: one ProLiant cable set is required for DL360 or 380 server; one 3PAR cable set is required per enclosure; one Synergy cable set is required for one Synergy frame), there are few exceptions. Consider for example HPE Networking Comware switches or Apollo servers, many of them can run with two power supplies, yet some models can have more.
Step 2: Select required number of grounding bars
Add one grounding bar kit (Q9N54A) for each breaker panel kit (G2H92A). The grounding bar attaches to the back of the E-T-A breaker panel, and does not consume rack space. It is the central grounding point where all equipment connected to the breaker panel will have their ground wires connected, and which will be further on connected to the Data Center ground at installation location.
Step 3: Select required grounding cables
This step applies to c7000 blade enclosures only, for which there are two different E-T-A grounding cable kits. All other E-T-A power cables (for equipment with less power draw) are 3-wire cables where the ground wire is within in the same cable than the 48V DC plus and minus conductors. Synergy frames have their own HPE Synergy DC Power Grounding Kit (872034-B21), which contains grounding cable to be connected to rack frame.
Step 4: Select the required number of DC power cables
Select required number of optimal length cables, depends on the exact rack layout planned. Choosing right length of cables is more important in DC powered racks than in AC powered ones, because DC cables need to be thicker, and excess length is harder to fit into the rack.
Step 5: Select the required quantity of circuit breakers of each rating needed in your configuration
Select circuit breaker of correct rating for each power supply to be connected. Recommendations for the right sizes are after the circuit breakers listing..
Factory Express Rack Integration
Ordering your choice of E-T-A power products pre integrated into racks at HPE prior to shipping, is possible only by utilizing HPE Factory Express services.
For more than ten years, HP and latterly Hewlett Packard Enterprise, has been building, testing and deploying fully integrated, high quality data center, branch office and OEM solutions from its manufacturing facilities across the globe.
