Power Harness¶

Overview¶

The Hako-Core power harness system distributes clean, regulated power from the central powerboard to individual PCBs throughout the chassis. This modular approach ensures efficient power delivery and simplified cable management.

The power harness acts as the distribution network between the central powerboard and the individual backplanes.

SAS Cable Variants¶

Short Harness (18" / 45cm)¶

Use case: PCBs in first two rows from the front of the chassis
Quantity needed: 1-8 per system

Medium Harness (24" / 60cm)¶

Use case: PCBs in first two rows from the front of the chassis
Quantity needed: 1-8 per system

Long Harness (36" / 90cm)¶

Use case: PCBs in the 3rd and 4th rows from the front of the chassis
Quantity needed: 1-8 per system

Installation¶

Safety First

It is always recommended to power down the system when working inside the case.

Installing SAS Cables¶

Plan route from PCB to Motherboard
Use appropriate length SAS cables for each connection
Route along chassis edges for longer runs (See Diagram Above)
Connect SAS cables to PCBs and ensure each cable is snug with a gentle pull test
