Notes:1. This port can be in DVI-D or HDMI (HDMI available upon request).

2. This port is a DP/HDMI combo port but can only transmit HDMI signals (unless wired as a DP port). Please plug in a DP or an HDMI cable with the right orientation and alignment to avoid damage to the connector. You should feel resistance (due to a pin on the right) if the cable is not inserted correctly. For detailed instructions, see https://youtu.be/SUj07rfN5l8.

2Quick Installation Guide |

Installing a 2.5" SATA DriveThe SATA drive bay can be easily accessed witout opening the system. However, the system does not support hot-swapping hard drives; turn off the system first before proceeding with the following procedure for installing a SATA drive. Locate the drive bay on the front panel and open it by releasing the handle. Slide the HDD into the drive bay. Note that the HDD should be positioned vertically with the SATA data connector on top of the power connector to correctly engage with the system's SATA connectors. Then close the drive bay and lock the handle.

Notes:1. The slot is desgined to exactly fit a 2.5" SATA drive with 7mm thickness; it cannot fit

SATA drives with other sizes.

2. Do not force to close the drive bay if the HDD is not correctly inserted.

Removing the Chassis CoverPlease observe the following guidelines and follow the procedure to open the system.

1. Service or maintenance procedures should only be performed by trained technicians.2. Ground yourself by using a wrist grounding strap to prevent electrostatic discharge.3. Make sure the connected system or computer and all other devices connected to it have been

powered off.4. Disconnect all power cords and cables.5. The 5 mounting screws on the top cover of the system are used to secure the cover to the

chassis. Remove these screws and then put them in a safe place for later use.6. After removing the mounting screws, lift the chassis cover to open the system.

Installing Devices

Installing a SODIMM

Installing a Mini PCIe Card The system board is equipped with 2 Mini PCIe slots: full-size (black) and half-size (white). The half-size slot provides USB & SATA interfaces whereas the full-size slot provides PCIe and USB interfaces.

The system supports two DDR4 SODIMM sockets (dual channel).

Installing a PCIe Expansion Card

Important:When inserting expansion cards into the system unit, please select a standard card within 303x126x41 (LxWxH) mm in order to fit into the system chassis.

Note: The EC532-KD-AI6881 provides one PCIe x16 and one PCIe x4 (x 1 lane) expansion slots with the H320-2E riser card. The EC533-KD-AI6881 and EC533-KD-AI3G46E one PCIe x16 and two PCIe x4 (x 1 lane) slots with the H320-3E riser card.

To install an expansion card, you need to first remove the slot plates and bracket by uninstalling the thumb screws on the front panel.
