Repair History

The Repair History sub-page provides a chronological log of all maintenance activities performed on mining equipment. Accessible from the Inventory sidebar, this view enables operators to track part replacements, diagnose recurring issues, and audit technician activities.

For documenting repairs with notes, see Comments. For spare parts tracking, see Spare Parts Inventory.

Repair Records Table

The main table displays repair events in reverse chronological order.

Column	Description	Related Documentation
Date	Timestamp when repair was logged	—
Associated Device	Miner code that received the repair	Miner Short Codes
Changes	Summary of part additions and removals	Change Summary Format
User	Email address of technician who performed the repair	User Management

Each row can be expanded using the "+" icon to reveal detailed part change information.

Expanded Part Details

Expanding a repair record displays a nested table showing individual component changes.

Column	Description	Related Documentation
Type	Component category (Controller, PSU, Hashboard)	Spare Parts Inventory
Serial Number	Part serial number or QA inventory reference	—
MAC	Network MAC address (for control boards)	—
Changes	Direction indicator (Added or Removed)	—

When no parts were physically changed during a repair (e.g., software-only fixes or status updates), the expanded section displays "No data".

Change Summary Format

The Changes column uses a compact notation indicating parts added and removed during the repair.

Format	Meaning	Example Scenario
0 Additions, 0 Removals	No physical part changes	Software update, status change
-1 Additions, 0 Removals	One part removed, none added	Part removed for testing
1 Additions, 1 Removals	One part swapped (removed and replaced)	Faulty part replacement
2 Additions, 0 Removals	Two parts added	Installing new components
0 Additions, 2 Removals	Two parts removed	Stripping for parts

Negative addition values indicate parts were removed from the miner. This tracking enables accurate inventory reconciliation between Miners Inventory and Spare Parts Inventory.

Understanding the Math

When a part swap occurs:

• 1 Addition: New part installed from spare inventory

• 1 Removal: Old part returned to spare inventory (status: Faulty or Recovered)

This bidirectional tracking ensures:

• Spare parts inventory stays accurate

• Part history is fully auditable

• Cost accounting reflects actual part consumption
