PCB Installation

Overview

This guide covers the proper mounting procedures for all backplane types and ensures secure connections.

Each PCB in the Hako-Core system provides power regulation and data connectivity for a specific set of drives. Proper installation ensures optimal performance and system reliability.

PCB Types

The Hako-Core and Hako-Core Mini support several PCB configurations:

Standard Size Backplanes

  • 4-HDD Backplane: 3.5" drive support
  • 12-SSD Backplane: 2.5" drive support
  • 4-U.2 Backplane: 2.5" drive support

Small Size Backplanes

  • Mixed 4-Bay Backplane: Combined 2.5" and 3.5" support

Safety First

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

Removal Procedure

The removal procedure is the same for all 4 variants of backplanes sold by HakoForge

Power off the machine.

  1. Unscrew the 4 black hex head bolts securing the PCB to the standoffs
  2. Lift the PCB and detach the data and power cables
  3. Remove the PCB from the case.

Installation Procedure

PCB Mounting Overview

Safety First

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

Identify Mounting Location

Each PCB has designated mounting locations within the chassis:

Power off the machine.

  1. Locate standoffs in chassis for your PCB position
  2. Connect the data and power connector to the PCB

  3. Align PCB over the mounting standoffs

    (Note: if you are replacing an existing PCB and the fans and neighboring PCBs are already installed connect the power and data cables before screwing the PCB into the standoffs.(Shown in video below))

  4. Verify all mounting holes align with standoffs

  5. Secure PCB with provided hex screws. (Recommended to start opposite corners first, do not overtighten.)

Torque Specification

Be aware of cross threading when first turning the screw.
Do not over-tighten screws. PCBs can crack under excessive pressure.
Tighten just until snug with no movement.

Verification Steps

Visual Inspection

After installation, verify:

  • PCB sits level and secure
  • All screws properly tightened
  • No visible cable stress or interference
  • Any connectors are fully seated

Electrical Testing

Before installing drives:

  1. Power on system (without drives)
  2. Check PCB power LEDs if present
  3. Test with single drive before full installation
