DELL Chromebook 3400 30-pin USB IO Ribbon Cable 3XRT5

SKU CH-8KPD-CYDK7

Genuine Dell OEM 30-pin ribbon cable connects the USB IO board to the motherboard on the Chromebook 3400

  • Genuine Dell OEM part ensures exact fit
  • Connects USB I/O board to motherboard
  • 30-pin ribbon cable for right-side USB I/O
  • Designed specifically for Chromebook 3400 laptops
  • One of two cables linking the I/O board

Genuine Dell OEM Ribbon Cable

This genuine Dell OEM ribbon cable carries the part number 3XRT5 and connects the right-side USB I/O board to the motherboard inside a Chromebook 3400. It is a brand-new replacement component sourced directly from the original manufacturer.

30-pin Connector Interface

The cable uses a 30-pin connector that matches the specific header on the Chromebook 3400 I/O board. This pin count is the single specification that determines whether the part will fit; it is not interchangeable with the second cable used on the same board.

Restores Two USB Ports

Installing this cable restores the two USB ports on the right side of the laptop when the original ribbon has failed or been damaged. It does not add extra ports or support other laptop models, so builders repairing a different chassis will need the correct cable for that device.
