Use the Intel® Endpoint Management Assistant Configuration Tool (Intel® ECT), or Intel® Remote Provisioning Client (device-management-toolkit/rpc-go).
| Notes |
Intel® Active Management Technology (AMT) is integrated into the firmware known as the Intel® Management Engine (ME). Intel® AMT version matches the Intel® ME version on a system. |
Steps to get into the MEBx
Starting from Alder Lake platforms with Raptor Lake CPUs running Intel® ME (AMT) 16.1 firmware, remote connections to unsecure TCP/IP port 16992 are no longer supported. TLS port 16993 must be used for connecting to Intel AMT.
Starting from Intel® AMT 19 firmware on Arrow Lake platforms, connecting to Intel® AMT without TLS is not supported at all (local connections must use TLS port). Port 16993 is a requirement.
The device can be accessed using the device’s fully qualified domain name (FQDN) or IP address.
