This tempting but unsafe shortcut is not a sufficient remediation for DGX rack load and rail placement: Assume that any 19-inch rack carrying enough free rack units automatically supports any GPU chassis weight or rail kit. Observed scenario: A deployment team assigns four high-density GPU systems to a rack without checking floor loading or rail positions. The governing mechanism is: Heavy GPU systems require rated mechanical support and correct mounting; a rack-unit count alone does not establish safe physical deployment. The proportionate action is: Check rack dimensions, floor load and rail compatibility, then place approved chassis using the vendor's supported installation sequence. A direct check is: Review rack load calculations, platform dimensions, rail kits, equipment placement plan and recorded installation inspections. The acceptance condition is: All nodes are securely mounted in compatible rack positions and mechanical inspection passes without blocked service access.

This alternative is relevant to Dual-feed rack power and PDU mapping but does not directly resolve the current DGX rack load and rail placement issue: A planned single-feed isolation leaves required servers within power limits and serving their intended workloads. Observed scenario: A deployment team assigns four high-density GPU systems to a rack without checking floor loading or rail positions.

This alternative is relevant to Dual-feed rack power and PDU mapping but does not directly resolve the current DGX rack load and rail placement issue: Trace each power supply to independent approved rack feeds and test safe loss of either feed within the supported power budget. Observed scenario: A new AI pod leaves heavy compute trays above unsupported rack sections and installers report misalignment.

This tempting but unsafe shortcut is not a sufficient remediation for DGX rack load and rail placement: Assume that any 19-inch rack carrying enough free rack units automatically supports any GPU chassis weight or rail kit. A new AI pod leaves heavy compute trays above unsupported rack sections and installers report misalignment.

That option concerns Liquid cooling supply and leak interlocks. Heavy GPU systems require rated mechanical support and correct mounting; a rack-unit count alone does not establish safe physical deployment.

This alternative is relevant to BMC network bring-up and out-of-band separation but does not directly resolve the current DGX rack load and rail placement issue: Check controller address configuration, switch OOB paths, login records, firmware identity and host-off connectivity. Observed scenario: A new AI pod leaves heavy compute trays above unsupported rack sections and installers report misalignment.

This alternative is relevant to TPM state and measured secure boot but does not directly resolve the current DGX rack load and rail placement issue: Inspect TPM ownership and event logs, secure-boot state, signed firmware path and expected PCR measurements.
