Quanta Cloud Technology (QCT) QuantaGrid Server BMC / IPMI 2.0 (D51B-2U / S31A-1U / T21P-4E / S210-X12RS series) — Default Password

Default username and password for the Quanta Cloud Technology (QCT) QuantaGrid Server BMC / IPMI 2.0 (D51B-2U / S31A-1U / T21P-4E / S210-X12RS series): qct.admin / qct.admin. Learn how to log in and how to change the default credentials.

QCT servers use an AMI-based BMC firmware with a fleet-wide default credential qct.admin/qct.admin (both all-lowercase). The BMC exposes full IPMI 2.0 over LAN (UDP port 623), KVM-over-IP, SOL (Serial over LAN), and an HTTPS web interface. Some newer QCT chassis print a unique factory BMC password on the server label — verify the label before testing generic defaults. QCT documentation advises changing the password immediately on first login.
