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.

Quick Installation Guide |
Installing a 2.5" SATA Drive
The 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 rst 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 t a 2.5" SATA drive with 7mm thickness; it cannot t
SATA drives with other sizes.
2. Do not force to close the drive bay if the HDD is not correctly inserted.
Removing the Chassis Cover
Please 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 t 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 rst remove the slot plates and bracket by uninstalling the
thumb screws on the front panel.
