Using one minimum firmware number for every Blackwell system
Platform releases, component firmware versions and feature prerequisites are different identifiers. Use the matching supported bundle.
Operator task guide
Blackwell event and firmware decision matrix
Start with the exact platform and event, not the Blackwell name alone. B100, HGX/DGX B200 and DGX GB200 NVL72 do not share a universal firmware release number or identical switch-management workflow.
Use the full NETIR variant, fatality, recovery action, installed stack and event timing to select the vendor procedure. A GPU Xid, legacy switch SXid and NVSDM switch counter are different evidence types. This matrix is documentation-backed triage, not a hardware certification or permission to reset a production fabric.

Step-by-step method
- 1
Identify the platform before choosing a runbook
Record the server/OEM model, GPU generation, partition topology and exact driver, VBIOS, fabric-management and switch software versions. Use the platform component inventory; the DGX software release identifier is not a universal VBIOS version.
- 2
Preserve the complete event and peer context
Retain the original host and switch records, GPU/port identities and event sequence. Keep NETIR names and payloads, fatal/non-fatal labels and the action carried by Xid 154. Compare peer records and account for clock skew before assigning fault ownership.
- 3
Match timing to a documented advisory
For DGX GB200 NVL72, distinguish extended uptime from an event immediately following reset. Release 1.3.6 documents the long-uptime NVLink management microcode correction; 1.3.10 and 2.0.0 describe a separate post-reset MSE communications race. Neither description proves the cause of an arbitrary 150/154 pair.
- 4
Choose a supported stack, not an isolated firmware guess
Follow the current release and OEM compatibility requirements. The 2.0.0 notes specify driver 580 TRD6 or later and the recommended 2.0 software/firmware stack for listed resiliency features. That is a feature-specific prerequisite, not a universal minimum for every Blackwell incident.
- 5
Coordinate recovery and verify the original operation
Drain or isolate workloads and obtain operator approval before any reset, firmware update, service restart or power cycle. Preserve diagnostics first. Afterward check expected fabric membership, port state, representative workload results and recurrence. An immediate clean run cannot validate a defect that only emerges after extended uptime.
Event, platform and firmware applicability
| Signal | What it means | Next action |
|---|---|---|
| B100 or B200 identification without full server/stack details | Architecture alone is insufficient to select firmware or recovery scope. | Use the exact platform/OEM support matrix. Do not apply a DGX GB200 bundle or legacy SXid recovery procedure by name similarity. |
| Blackwell Xid 149 with a NETIR variant | The subcode, payload, fatality and peer topology determine interpretation. | Use the exact catalog variant and collect both endpoint records before selecting a recovery or investigatory action. |
| DGX/HGX B200/B300 switch investigation | NVIDIA documents NVSDM-based switch telemetry rather than the legacy fatal/non-fatal SXid reporting model. | Use the platform switch telemetry and management guidance. An older SXid-only alert rule is not adequate evidence of switch health. |
| DGX GB200 NVL72 extended uptime with applicable MSE events | Release 1.3.6 documents an NVLink management microcode overflow correction after approximately 60+ days. | Compare installed stack and timing with that advisory. Use an approved platform bundle and preserve a recurrence baseline. |
| MSE events immediately after reset | The release notes describe a distinct communications reinitialization race. | Compare with the post-reset advisory in 1.3.10/2.0.0 instead of diagnosing the uptime defect from the same event numbers. |
| Xid 154 following another event | Recovery-action information must be read alongside the initiating fault. | Capture the actual action and follow platform prerequisites. Do not convert the number into a blanket reset or RMA instruction. |
| Legacy NVSwitch SXid on a covered earlier platform | Severity and GPU-facing versus baseboard-facing ports affect the blast radius. | Follow that platform Fabric Manager workflow. A single-device recovery may not cover an inter-baseboard fabric fault. |
| HBM ECC or row-remapper event | Containment, remap pending/failure state and architecture-specific repair behavior matter. | Use memory-management and field-diagnostic guidance. A single counter or remapped row is not a replacement verdict. |
Evidence checklist
- Exact platform and OEM model, topology and partition scope
- Installed driver, VBIOS and management/switch stack inventory
- Full GPU and switch event records with identities and order
- Uptime and reset/maintenance history
- Expected fabric state, affected workload and post-recovery results
Common mistakes
Calling a replacement unnecessary before checking evidence
A documented firmware defect is an alternative explanation, not proof that hardware is healthy.
Treating a reset as passive screening
A reset, service restart or power cycle can affect other workloads and erase evidence. Scope and authorize it through the operator.
Tools and deeper references
GB200 uptime and MSE timing
Inspect the documented uptime and post-reset distinctions.
NETIR variant and endpoint checks
Preserve complete event details before local or peer fault attribution.
Legacy SXid scope
Apply the correct switch event model to the actual platform.
ECC and remapping evidence
Separate containment, recovery and service eligibility.
Xid reference hub
Compare event families and evidence requirements.
Frequently asked questions
Can this matrix choose the correct firmware automatically?
No. It identifies documentation and evidence boundaries. The platform/OEM support matrix and installed component inventory determine an approved update.
Do Xid 150 and 154 prove the long-uptime bug?
No. Check installed stack, full events and timing. A separate post-reset issue can produce related events.
Does this guide report a reproduced Blackwell hardware recovery?
No. It is a documentation-backed reference and does not claim a physical experiment or customer incident result.
