Teaching guide · Miner Technician 2

Independent field work

Take a field issue from the first report to a verified resolution or a well-supported escalation.

Starting knowledge

Tech 1 outcomes or equivalent experience. Field tasks require your site's authorization and applicable supervision.

Teach the explanation before assessing it. Clarify vocabulary, use worked examples and give learners time to read all lessons in each section. No required case workbook or written rubric accompanies the course.

Section 1

Diagnostic method & connectivity

Own the job from report to resolution

Plan a safe investigation, preserve evidence and choose the next useful check.

Learning objectives

Define scope and expected behavior.
Choose a check that separates plausible causes.
Set a verification plan before making a change.

Explanation sequence

Diagnosis is the study of cause
Scope separates local and shared problems
Independent does not mean unsupported
Build a short list of explanations
Close the loop
Worked example: decide before restarting

Separate power, network and pool faults

Use which equipment is affected to decide where to look first.

Learning objectives

Compare miner, network and pool visibility.
Recognize common infrastructure dependencies.
Escalate electrical and network work with useful evidence.

Explanation sequence

From an Ethernet connection to a mining session
Configuration belongs in the diagnosis
Trace dependencies without confusing layers
Worked example: management works, pool does not

Section 2

Computing performance & cooling

Diagnose reduced hashrate and missing chains

Read hashrate measurements, check chain status against what the model should report, and explain reduced hashrate without guessing a part.

Learning objectives

Distinguish a local performance problem from a pool measurement or delivery problem.
Calculate output loss using an appropriate baseline and time window.
Separate missing, underperforming and deliberately limited chains.
Rank competing explanations and choose evidence that could disprove them.
Explain corrective-action selection and measurable verification.

Explanation sequence

Start with a precise complaint
Follow the measurement from miner to pool
Quantify the loss without inventing a cause
Read chain status as a pattern
Reconstruct the first meaningful event
Build a hypothesis that can lose
Choose an action with a verification contract
Verify the original failure, not just a successful boot
Write the handoff another shift needs
Worked example: symptom versus component claim

Diagnose cooling and thermal limits

Distinguish local cooling faults from a shared environmental problem.

Learning objectives

Interpret cooling data using model-specific limits.
Recognize shared thermal patterns.
Protect safeguards while investigating.

Explanation sequence

Heat removal is a complete path
Temperature readings describe locations
Read a thermal pattern over time and space
Do not trade protection for output
Worked example: the last row heats first

Assessment after all lessons: 12 questions. Use the feedback to identify the concepts that need another explanation.

Section 3

Controlled changes & verification

Manage firmware and configuration changes

Confirm compatibility, preserve configuration and make recoverable changes.

Learning objectives

Check exact hardware and firmware compatibility.
Prepare a rollback or recovery plan.
Limit changes and validate their results.

Explanation sequence

Firmware and configuration are different
A change needs a comparison
Prepare before changing anything
Validate a small, representative change
Worked example: a pilot that cannot represent the fleet

Verify recovery and close the job

Prove the agreed outcome, record what is still uncertain and hand the job to the next owner.

Learning objectives

Distinguish recovery from a verified resolution.
Check useful work across a meaningful interval.
Write a closure or escalation record another shift can trust.

Explanation sequence

Recovery is an observation over time
Resolution and explanation are separate conclusions
Choose verification that matches the original failure
Worked example: the green dashboard

End-of-level assessment

Review all course units before the comprehensive assessment. Keep knowledge results distinct from workplace competence, and explain what additional site training is needed.
