Power Options
ArkKVM offers flexible power options, allowing you to choose the method that best fits your setup.
Intelligent Power Sharing (ATX Integration)
When connected to the ATX control board via the RJ12 cable, ArkKVM supports bi-directional power delivery between the two devices:
- If the ATX board is powered, it can supply power to ArkKVM
- If ArkKVM is powered, it can supply power to the ATX board
- When connected to a PoE switch, ArkKVM can receive power via Ethernet and pass it to the ATX board
This flexible power-sharing design simplifies deployment and ensures reliable operation across a wide range of setups, including complex or headless environments.
USB-C (Powered by Host Computer)
The most common way to power ArkKVM is via its USB-C port, connected directly to the host computer. Many systems provide constant 5V power through USB; however, in some cases, this feature must be enabled in the BIOS or UEFI (often labeled as “USB Power During Standby” or “USB Always On”).
If the device does not power on automatically, please verify that this setting is enabled.
Even if USB power is enabled on your PC, some systems may briefly cut power to USB ports during a restart. This can cause the KVM to power off, potentially making you miss the timing to enter BIOS/UEFI.
If this happens, consider using an alternative power option.
Power over Ethernet (PoE)
ArkKVM features a built-in PoE module with support for IEEE 802.3af/at. When connected to a PoE-enabled switch via the RJ45 port, it can be powered directly without the need for an external adapter.
USB-C Power/Data Splitter (Included)
ArkKVM includes a USB-C Y-splitter cable that separates power and data connections. This allows you to connect to the host computer for data while supplying power from an external 5V source, such as a USB charger (not included).
Use this setup if the host computer does not provide stable or continuous USB power and PoE is unavailable.
When powering ArkKVM via the Power branch of the Power/Data Splitter cable using an external adapter, ensure the adapter provides a stable and regulated 5V output. Voltages exceeding 5V may cause irreversible damage to the device.
ATX Power Control Extension
For desktop PC integration, ArkKVM can be connected to the ATX power control board via the RJ12 interface. Power can be supplied from the ATX side (depending on whether the ATX board is powered via its USB-C port), enabling a clean and reliable internal setup without the need for external adapters.
