Category Outline Of HPE 879840-001 PDB-HDD B/P Cable Kit

The HPE 879840-001 cable kit—commonly described as a 2x mini12pin-mini12pin pair, 18 inch PDB-HDD backplane/power cable—is an OEM-grade server interconnect assembly designed for reliable power and signal routing between power distribution boards (PDB) and hot-swap hard drive backplanes. This category covers genuine HPE replacement kits, OEM equivalents, and high-quality compatible assemblies engineered to meet rack-server requirements for enterprise storage systems. Buyers searching this category typically need robust, durable cabling for ProLiant servers, blade chassis, or storage enclosures where multiple mini12pin connectors are used to carry power and management signals to drive bays.

Primary use cases and target systems

These cable kits are primarily used in enterprise data centers, hosting facilities, research clusters, and any environment running HPE ProLiant or HPE storage enclosures where drive backplanes and PDBs require mini12pin connectors. Typical scenarios include:

• Replacing worn or damaged PDB-to-backplane cables during server maintenance.
• Upgrading or retrofitting older HPE servers with new drive arrays.
• Stocking spare parts for preventive maintenance in server racks.
• Building or repairing custom storage arrays requiring OEM-style connectors.

Technical specifications and dimensions

Connector type and pinout

The defining feature of this cable category is the mini12pin connector at both ends. Each cable is a mini12pin-to-mini12pin assembly, meaning the two identical connectors mate with corresponding mini12pin headers on the PDB and on the HDD backplane. Pinout mapping and wire assignments typically follow HPE’s factory standard for power, ground, and control lines—ensuring safe transfer of DC power and drive management signals such as activity LEDs, presence detection, and enclosure management communications.

Cable length and tolerance

• Nominal length: 18 inches (approximately 45.7 cm).
• Tolerance: +/- small manufacturing tolerance to allow for routing and strain relief.
• Length optimized for 1U–4U rack servers where space is constrained but a short, serviceable cable is ideal.

Electrical ratings

These cable kits are rated for server power levels—sufficient for typical 3.3V/5V/12V rails used in backplane/power distribution applications—depending on the particular pin assignments. Typical features include:

• Current carrying capacity suited for multiple drive bay power demands.
• Insulation rated to standard server operating temperatures (up to ~80°C continuous in many designs).
• Compliance with common electrical safety norms for internal server cabling when provided by OEM.

Compatibility and model matchups

HPE product families and chassis

The HPE 879840-001 cable kit is commonly used with a variety of HPE ProLiant servers and certain storage enclosures. While model compatibility varies depending on backplane and PDB revisions, key families include:

• HPE ProLiant rack servers (e.g., DL series).
• HPE Gen-series storage chassis that use mini12pin connectors for internal power/distribution.
• Older and some newer backplanes that rely on mini12pin pairs for drive power and signaling.

How to confirm compatibility before purchase

1. Check the existing cable: verify the part number printed on the cable or tag. OEM parts often carry the HPE part number on a sticker or molded into the connector housing.
2. Examine connector shape and latch style: mini12pin connectors have a distinct rectangular profile and latch mechanism—confirm visual match.
3. Match pin count and orientation: ensure both ends on your existing assembly map exactly to the replacement.
4. Compare length requirements: 18 inches is standard for internal routing; if your chassis requires longer routing, search for a longer equivalent or use cable management options.
5. Consult server maintenance guides or HPE part catalogs when available to confirm exact part-to-chassis mapping.

Cross-references and aftermarket equivalents

When OEM parts are not available, the market often provides aftermarket compatible assemblies labeled as “HPE compatible” or “for ProLiant” with identical connector types and wire counts. When choosing cross-reference parts, evaluate:

• Build quality and connector specification—prefer gold-plated contacts and molded strain relief.
• Seller reputation—look for vendors that offer returns and warranty.
• Certifications—RoHS, CE, UL listings preferred for safety-conscious environments.

Purchase considerations and buyer guidance

OEM vs aftermarket options

When purchasing, you’ll typically see two categories of sellers: those offering genuine HPE 879840-001 OEM kits and those offering compatible aftermarket equivalents. Consider the following:

• OEM parts: Highest confidence in compatibility and original HPE specifications—may carry HPE part labels and warranty.
• Aftermarket parts: Can be cost-effective, but vet quality (plating, jacket materials, seller reviews, return policies).

Bulk purchasing and inventory planning

For data centers and managed service providers with multiple chassis, buying in small bulk packs reduces procurement cycles and supports rapid response to hardware failures. Keep a simple spare parts matrix that includes:

• Quantity based on server fleet size and historical failure rates.
• Compatibility notes per chassis and PDB revision.
• Storage conditions (cool, dry to avoid connector oxidation).

Price and warranty considerations

• Expect price variance depending on OEM labeling and warranty offerings.
• Check seller warranty terms; some vendors provide 30–90 day returns while OEM sellers may include longer warranty coverage.
• Consider total cost of downtime versus parts cost—higher-quality cables can justify a premium in mission-critical environments.

Performance comparisons and alternatives

Mini12pin vs other connector types

Mini12pin connectors provide a compact, multi-pin interface suitable for modern backplanes. Compared to larger multi-pin connectors or individual wire harnesses, mini12pin cables offer:

• Cleaner routing and fewer individual connectors to manage.
• Secure latch mechanisms to resist vibration-induced disconnection.
• Better factory-tested pin assignments that reduce human error during installation.

When to choose custom-length or shielded alternatives

Custom-length cables may be necessary if your rack layout requires non-standard routing. Shielded variants are recommended in high-EMI environments or where signals are particularly sensitive. Always ensure custom solutions maintain correct pin mapping and current capacity.

Regulatory, safety, and environmental factors

Regulatory compliance

Look for products that comply with RoHS and other regional restrictions on hazardous substances. OEM parts typically adhere to these standards; reputable aftermarket vendors may provide compliance documentation upon request.
