2.2.3.2 Add-in Card Connectors
The board has the following add-in card connectors:
One PCI Express 2.0 x4 connector. The x4 interface supports simultaneous
•
transfer speeds up to 500 MB/s of peak bandwidth per lane, per direction, for up to
4 GB/s concurrent and bi-directional bandwidth.
• One PCI Express Half-Mini Card slot
One PCI Express Full-/Half-Mini Card slot (removable stand-offs in full-length keep
•
out zone allows repurposing of Full-Mini Card slot into Half-Mini Card slot)
2.2.3.3 Power Supply Connectors
The board has the following power supply connectors:
•
External Power Supply – the board can be powered through a 19 V DC
connector on the back panel. The back panel DC connector is compatible with a
7.4 mm/OD (outer diameter) and 5.1 mm/ID (inner diameter) plug, where the
inner contact is +19 (±10%) V DC and the shell is GND. The maximum current
rating is 12 A.
Internal Power Supply – the board can alternatively be powered via the internal
•
19 V DC 1 x 2 power connector, where pin 1 is GND and pin 2 is +19 (±10%) VDC.
