HPE 536646-001 DL180 G6 Fan Cable Splitter

HPE 536646-001 is a fan power Y-cable with a straightforward but important job: connecting two fans to one power cable in compatible HPE systems. HPE parts information uses exactly that description, and the cable appears in DL180 G6-era server and storage platforms, including systems built around similar HPE architecture. For a chassis being rebuilt with paired or redundant cooling fans, the Y-cable can be the small component that completes the power path to the fan set.

How the Y-Cable Supports the Cooling Layout

A Y-cable takes one power connection and branches it to two fan connections. That arrangement is useful in systems where the supported cooling configuration calls for paired fans. The cable does not carry SAS data, SATA data or external power; it belongs entirely to the internal cooling subsystem.

This distinction matters when a server has been stripped for parts. Replacement fans may be available, but they cannot reproduce the intended paired arrangement if the branching power lead is missing.

Where HPE 536646-001 Appears

HPE documentation lists 536646-001 in G6-era server-derived systems, and StoreOnce parts information identifies it as the fan power Y-cable. It is also encountered in DL180 G6-related and P4000/StorageWorks environments. These storage appliances often share underlying server architecture, which explains why a ProLiant-style cooling component can appear in storage-node parts lists.

Product Role in One View

• Manufacturer: HPE
• Part number: 536646-001
• Component: Fan power Y-cable
• Function: Connects two fans to one power cable
• Installation: Internal chassis
• Hardware context: DL180 G6-era server and storage systems

Why This Small Cable Can Stop a Rebuild

Cooling hardware is frequently removed as a group when a system is used for donor parts. A replacement chassis may therefore contain the fan positions and system-board connections but lack the splitter required by the intended fan arrangement. 536646-001 gives the technician a specific HPE service reference for that missing piece.

It is also easy to hold as maintenance stock. For organisations running several similar nodes, one spare Y-cable takes very little storage space but can help return a cooling configuration to service after a cable fault or parts swap.

Other HPE Splitter, Power and Data Cables

The HPE 418008-001 Molex splitter is another branching power component, but it belongs to a StorageWorks 1U chassis rather than the fan-power role described here. The HPE 504660-003 cable handles an internal graphics/PCIe power requirement in Gen8 hardware, while the HPE 532393-001 cable kit combines several server cable types.

Storage data is separate. The HPE 498425-001 Mini-SAS cable provides a 28-inch internal SAS connection, and the HPE 493228-002 cable serves a shorter DL360 G6/G7 Mini-SAS route. These products may exist in the same equipment estate but perform entirely different jobs.

New and Refurbished for G6-Era Systems

New 536646-001 stock can suit a planned rebuild or a small preventative spares inventory. Refurbished cables are a natural fit for mature HPE systems that remain in active use. The objective in either case is to restore the intended fan-power arrangement with the recognised HPE component.

Supporting Redundant Cooling

Paired fan layouts can form part of a system’s cooling and availability design. Restoring the fans without their correct power distribution leaves that layout incomplete. The Y-cable therefore has practical value beyond its size: it helps the supported chassis power the fan pair as intended.

Order HPE 536646-001

Euroland IT Store can supply enterprise replacement parts such as HPE 536646-001 in New or Refurbished condition where available. Contact the team if you are sourcing fan, power and storage components together for a DL180 G6-era server or storage-node refurbishment.

Fan Cabling During System-Board or Chassis Work

Fan power cabling can be disturbed when a system board, fan cage or related chassis component is replaced. The fans themselves may be transferred successfully while the original splitter remains with the donor hardware. In that situation, 536646-001 provides the recognised HPE reference needed to recreate the two-fan power branch. For service teams, identifying the cable separately from the fan assemblies is useful because it allows the cooling system to be checked as a complete set of fans, power distribution and chassis airflow components.

A Compact Spare with a Clear Operational Role

Fan splitters are inexpensive compared with the systems they support, but an absent cable can prevent the intended cooling configuration from being completed. Keeping the part number in maintenance records makes it easier to identify this small component during future fan or system-board work.

HPE 536646-001 FAQs

What does HPE 536646-001 do?

It connects two fans to one power cable.

Is it associated with DL180 G6 hardware?

Yes. The cable appears in DL180 G6-era server and related storage-system parts references.

Is it a storage data cable?

No. Its documented function is fan power distribution.

Why is it called a Y-cable?

One power connection branches to two fan connections.

Does it appear in storage appliances?

Yes. HPE parts listings include it in server-derived StoreOnce/StorageWorks and P4000-era contexts.

Can it replace a Mini-SAS cable?

No. It has a cooling-power function, not a SAS data function.
