Conformity & Certifications
EMI: FCC, CE, BSMI, C-Tick
Safety: ETL, CB, BSMI
Other: RoHS, Energy Star, ErP
This device is classed as a technical information equipment (ITE) in class B and is intended for use in living room and office. The CE-mark approves the conformity by the EU directives:
(1) 2004/108/EC relating to electromagnetic compatibility (EMC),
(2) 2006/95/EC relating to Electrical Equipment designed for use within certain voltage limits (LVD),
(3) 2009/125/EC relating to ecodesign requirements for energy-related products (ErP),
(4) 1999/5/EC related to Radio and Telecommunications Terminal Equipment (R&TTE)
 Jumper for COM port configuration
Pin 9 of the COM-Port is a multi-functional signal. Based on the Jumper JP1 configuration on the mainboard, it can be configured as Ring Indicator (RI) or external power supply with a voltage level of either 5 V or 12 V. Each COM port can be configured separately.
The operating mode of COM 1 can be set to RS232, RS422 or RS485 in the BIOS. COM 2 supports RS232 mode only.
 Limitations of the DisplayPort
Due to the design of the Intel chipset, the DisplayPort output of the DS77 Series is based on the Embedded DisplayPort (eDP) interface. Please be aware of the following restrictions when setting up your monitor.
1) The DisplayPort (DP) has no audio function. Please use HDMI for displays/TVs with integrated speakers.
2) Intel Collage Mode in Multi-Stream Transport (MST) mode is not available. Please use a native 4K display. Older monitors using Collage Mode are not supported.
3) PASSIVE adapters/cables cannot be used (e.g. DP-to-HDMI or DP-to-DVI). Please use a native DP connection or an ACTIVE adapter.
4) HotPlug is not supported. Please restart the system for the display to be detected.
Note: In a 3-display setup, the DP output won't show picture while booting in BIOS mode. It will be activated once the OS has loaded the display driver.
 Teaming Mode
The teaming function allows you to group both available network adapters together to function as a single adapter. The benefit of this approach is that it enables load balancing and failover.

 Four-pin header at the back panel
This header allows for connecting an external power button.
It also provides 5 V DC voltage for external devices and the Clear CMOS function. Optional accessory: the adapter cable CXP01.
 Caution: for high ambient temperatures higher than 35 °C we strongly recommend to use an SSD instead of an HDD
 Power on after power fail:
The BIOS setup provides a "Power-On after Power Fail" function that can be found under "Power Management Configuration". This function determines the PC's behaviour after power failure. As a matter of the nature of this function, it may fail after short power failures. This is why the Shuttle XPC slim Barebone DS77U3 also comes with a hardware-based solution. By removing Jumper J9 (please refer to the quick user guide) the system will start unconditionally once power is applied.
