5. Setup
5.1. Rack Mounting
The DKX3-808 is designed for standard 19-inch rack mounting. Use the included rackmount kit to secure the device in your server rack. Ensure sufficient space for airflow and cable management.
5.2. Power Connection
- Connect the provided power cords to the dual power inputs (1 and 2) on the rear panel.
- Plug the other ends of the power cords into separate, grounded AC power outlets or uninterruptible power supplies (UPS) for redundancy.
- Flip the power switches above each power input to the 'ON' position.
5.3. Network Connection
- Connect Ethernet cables from your network switch(es) to the LAN 1 and LAN 2 ports on the rear panel. Using both ports provides network redundancy.
- Ensure your network is configured to provide IP addresses to the KVM switch (DHCP or static IP).
5.4. Local Console Connection (Optional)
To use a local console:
- Connect a DVI monitor to the DVI-D port.
- Connect a USB keyboard and USB mouse to the USB ports labeled 'LOCAL USER'.
5.5. Connecting to Target Servers
Connect your servers to the KVM ports (1-8) using appropriate KVM cables (e.g., DVI/VGA/HDMI to RJ-45 KVM dongles, depending on server video output).
- Connect one end of the KVM cable to a KVM port (1-8) on the DKX3-808.
- Connect the other end of the KVM cable to the corresponding video, USB keyboard/mouse, and optional audio ports on your target server.
6. Operating Instructions
6.1. Initial Access
After powering on, the device will boot up. You can access the KVM switch via:
- Local Console: If connected, the local monitor will display the KVM switch's console interface.
- Remote IP Access: Open a web browser and enter the IP address of the KVM switch (default or DHCP assigned). Log in with the default credentials (refer to the Quick Setup Guide for initial login details).
6.2. Switching Between Servers
From the KVM switch interface (local or remote), you can select the desired server to control. The method for switching typically involves a graphical user interface (GUI) or hotkey commands.
- GUI Selection: Use the on-screen display (OSD) or web interface to navigate and select the server port.
- Hotkey Commands: Specific keyboard combinations (e.g., Scroll Lock + Scroll Lock) can be used to activate the OSD or switch directly between ports. Consult the full user manual for specific hotkey sequences.
6.3. Virtual Media
The Dominion KX III supports virtual media, allowing you to map a local CD/DVD drive or ISO image to a remote server. This is useful for software installation, patching, or system recovery.
- Access the virtual media feature through the remote KVM session interface.
- Select the local drive or ISO file to be mapped.
- The remote server will detect the mapped media as if it were locally connected.

- Local Console: Check DVI cable connection to the monitor and the KVM switch. Ensure the monitor is powered on and set to the correct input.
- Remote Session: Verify network connectivity to the KVM switch. Ensure the target server is powered on and its video output is functional. Check KVM cable connections to the server.
8.3. Keyboard/Mouse Not Responding
- Local Console: Ensure USB keyboard and mouse are connected to the 'LOCAL USER' USB ports. Try different USB ports.
- Remote Session: Verify the KVM cable connection to the target server's USB ports. Ensure the remote viewer application has focus.
8.4. Network Connectivity Issues
- Check Ethernet cable connections to LAN 1 and LAN 2 ports and to the network switch.
- Verify network settings (IP address, subnet mask, gateway) are correct.
- Ping the KVM switch's IP address from a connected computer.
8.5. Resetting the Device
If the device is unresponsive, a soft reset can be performed by pressing the 'RESET' button on the rear panel. For a factory reset, consult the full user manual or Raritan support documentation.
