Raritan Dominion KX III G2 Adds First API to Enterprise KVM
Enterprise KVM Switch API: Raritan’s Game-Changing Release
Enterprise data centre management has long relied on KVM switches to provide remote server access, but integration with modern infrastructure automation tools has remained limited. The lack of standardized APIs in this mature category has forced teams to rely on manual interventions and workarounds, slowing down operational efficiency.
The Raritan Dominion KX III G2 changes this by introducing the first API to the enterprise KVM range, enabling seamless automation and orchestration across your server infrastructure. Supporting up to eight concurrent users with BIOS-level remote control, this KVM-over-IP switch delivers the performance and reliability expected from an enterprise solution while finally bridging the gap between hardware management and software-defined infrastructure.
Legrand launched the Raritan Dominion KX III G2 on 15 July 2026. Enterprise KVM is a mature category where a generational release usually means faster silicon and a new interface. This one adds something the range has never had: an API.
A KVM matrix you can automate
The Dominion KX III G2 is an enterprise-class KVM-over-IP switch giving up to eight users remote BIOS-level control of connected servers. It is built on Xerus, the same architecture behind Raritan’s intelligent PDU portfolio, which puts the KVM and power lines onto a shared security and management platform.
The change that matters most for infrastructure teams is the management API. It is the first in a Raritan KVM matrix, designed for deployments from 10 to 10,000 devices, and the SDK ships free of charge. Workflows such as mouse movement, video capture, and integrations with internal tooling can be driven programmatically rather than through the GUI.
That closes a long-standing gap. Out-of-band access has historically been the one part of the infrastructure stack that stayed manual, because the appliance that reaches a failed server was itself only reachable by a human with a browser. An API on the KVM layer means recovery steps can be scripted alongside everything else.

Legrand positions the platform around recovery time rather than feature count, which is a shift in how this line has historically been sold.
“Because KVM works below the operating system layer, technicians can reach BIOS settings, restart systems into safe mode and begin recovery remotely. In many cases, this helps IT teams cut Mean Time to Recovery (MTTR) from days to minutes while reducing the need to dispatch someone on-site.” Legrand DPC, Dominion KX III G2 launch announcement, 15 July 2026
Definition: what BIOS-level access means
A KVM-over-IP switch connects to a server’s keyboard, video and mouse ports through a computer interface module, then transports those signals over the network. Because it operates on the physical console rather than through an agent installed in the operating system, it keeps working when the operating system does not.
That is the difference between a KVM and a software remote access tool. RDP, SSH and VNC all need a running, responsive OS with a working network stack. A KVM reaches the machine during POST, in BIOS or UEFI setup, at a boot menu, at a kernel panic, or when the OS has been compromised. It is the access path that survives the failure that made you need access in the first place.
If you already own DKX3
The launch has a second half. On 5 June 2026 Legrand announced end of life for the Dominion DKX3 range, covering ten part numbers.
Support runs to 31 December 2028, so nothing stops working soon. The date that drives decisions is earlier: last order date and last ship date are both 31 December 2026, on the same day, with no shipping grace period. Legrand has stated it holds minimal legacy DKX3 inventory and will release it case by case until it is depleted.
| Milestone | Date | What it means |
|---|---|---|
| End-of-Life announcement | 5 June 2026 | Public notification that the product has been discontinued. |
| Last Order Date | 31 December 2026 | Final date on which purchase orders can be placed. |
| Last Ship Date | 31 December 2026 | Final date a shipment can be requested. |
| End of Support | 31 December 2028 | Final date for engineering and technical support under contract or warranty. |
If you standardise on a single model across sites, or keep cold spares, the practical consequence is that any final DKX3 order has to be placed this year. After that the estate becomes mixed-model by default.
Replacement mapping
| Discontinued | Configuration | Replacement |
|---|---|---|
| DKX3-108 | 8 ports, 1 remote session | DKX3G2-108 |
| DKX3-116 | 16 ports, 1 remote session | DKX3G2-116 |
| DKX3-132 | 32 ports, 1 remote session | DKX3G2-132 |
| DKX3-216 | 16 ports, 2 remote sessions | DKX3G2-216 |
| DKX3-232 | 32 ports, 2 remote sessions | DKX3G2-232 |
| DKX3-416 | 16 ports, 4 remote sessions | DKX3G2-416 |
| DKX3-432 | 32 ports, 4 remote sessions | DKX3G2-432 |
| DKX3-808 | 8 ports, 8 remote sessions | DKX3G2-808 |
| DKX3-816 | 16 ports, 8 remote sessions | DKX3G2-816 |
| DKX3-832 | 32 ports, 8 remote sessions | DKX3G2-832 |
All ten carried a DVI local port and the G2 equivalents use HDMI, which is the one physical change to plan for at the rack. The DKX3-464 and DKX3-864 were retired under earlier announcements and also have G2 equivalents. The G2 range extends further than DKX3 did, adding a 96-port model, so a site currently splitting across two 64-port switches has a denser option.
Planning a migration
1. Audit against the ten part numbers
Match your asset list against the discontinued models. Raritan publishes a downloadable list of discontinued part numbers by product family, which is faster than working through individual notices.
2. Decide on a final DKX3 order before the December cut-off
This is the only decision with a hard deadline. Work out whether standardisation or spares justify a last order, because ordering and shipping both close on 31 December 2026.
3. Check the CIM guide against your installed base
The G2 supports a multiplatform CIM range including D2CIM-DVUSB for VGA, D2CIM-DVUSB-DVI, D2CIM-DVUSB-HDMI, D2CIM-DVUSB-DP, D2CIM-VUSB, D2CIM-VUSB-USBC, DCIM-USBG2 and DCIM-PS2. Check the guide against what you own rather than assuming a full carry-over, because CIM type determines virtual media, absolute mouse synchronisation, smart card and audio support.
4. Plan for a mixed estate, not a single cutover
CommandCenter Secure Gateway integrates SX II, KX III, KX III G2, KSX II and KX4-101 in one platform. A phased replacement across two or three budget cycles does not force two management systems.
5. Note the local port change
The local console port moves from DVI to HDMI. Where a rack has a fixed local monitor or a console drawer wired for DVI, add a cable or adapter to the deployment plan.

Email [email protected]Frequently asked questions
What is new in the Dominion KX III G2 compared with the KX III?
The G2 moves onto Legrand’s Xerus architecture and introduces the first management API in a Raritan KVM matrix, designed for 10 to 10,000 devices and supplied with a free SDK. It supports up to 60 fps video at 1080p with audio, 1920×1200 resolution, 24-bit colour and 50 ms latency, adds Secure Boot and an integrated TPM, uses a FIPS 140-2 certified cryptographic module with 256-bit AES, and is IPv6 certified. The local console port changes from DVI to HDMI, and the range extends to a 96-port model.
What can the KX III G2 API and SDK actually do?
Raritan describes the SDK and API as covering automation and custom application development, including workflows such as mouse movement, video capture, and integrations with internal tools. The API is designed for deployments ranging from 10 to 10,000 devices, and both the SDK and API are available free of charge.
Does the KX III G2 meet government security requirements?
Raritan states that the KX III G2 meets widely used US and Canadian government security mandates, including a FIPS 140-2 certified cryptographic module, smart card and CAC authentication with smart card, CAC or PKI login, two-factor RSA SecurID and IEEE 802.1X authentication, and IPv6. All data is encrypted including video transmissions and virtual media, and the appliance runs a secure Linux base with Secure Boot and an integrated TPM.
When does the Raritan Dominion KX III reach end of life?
Legrand announced end of life for the Dominion DKX3 range on 5 June 2026. The last order date and last ship date are both 31 December 2026, and end of support is 31 December 2028. Ten part numbers are affected, each with a direct DKX3G2 replacement.
Will my DKX3 switch stop working after end of support?
No. End of support is the last date for engineering and technical support under a service contract or warranty terms, not a shutdown date. The unit keeps operating. What ends is entitlement to firmware fixes, warranty RMA and engineering escalation, which is usually the point raised in a security or audit review of a management-plane device.
Can I run DKX3 and KX III G2 switches together?
Yes. CommandCenter Secure Gateway provides centralised access and management across SX II, KX III, KX III G2, KSX II and KX4-101 appliances, so a phased migration can run over several budget cycles without splitting the management platform.
