       Required hardware  
 
   1   

X680 4-port IPKVM switch x1

    2   

Raspberry Pi Compute Module 4 x1 (all variants Compatible)

  
               
   3   

16GB micro-SD card x1 (Required for CM4 wihtout eMMC)

    4   

CR1220 coin battery x1 (For Real-time clock)

  
               
   5   

HDMI cable A Male to A Male x4 (For HDMI video input)

   6   

M.2 NVMe 2280 SSD (Optional, for booting from SSD or storage expansion )

  
   7   

Ethernet cable x1 (Connect to your network)

    8   

X630-A5 ATX control PCI card (Optional, To control PC system power, system reset, read status of HDD LED and power LED)

  
   
   9   

Ethernet cable x4 (Optional, for use with X630-A5)

      

 

  
       
 
       Hardware installation  
 
  1 Unplug all the cables that are connected to the board.  
         
  2   Install a Compute Module into the connector of the Interface Board. Check that the Compute Module is oriented correctly before fully inserting it into the connector. Carefully align the two rows of connectors and press together evenly to snap together.

Caution: Take static precaution measures when handling the boards.		  
         
     

Confirm the Compute Module is correctly mated by looking at each corner of the Interface Board. 4 screw fixed hole are all visiable.

  
         
  3  

Installing the CPU cooling fan and insert the CR1220 coin battery (making sure that the battery is oriented correctly. Positive side(+) UP).

  
         
         
  4  

Insert the M.2 SSD into M.2 slot then slide the SSD drive into the M.2 slot at 30 degrees while pushing it gently till it fits into the slot. Notice that after insertion into the M.2 slot, the SSD drive inclined angle to the board. finally press the M.2 SSD drive till it sits on the riser screw then lock it in place using the M2 mounting screw.
