# Technical Inventory Hardware Extraction Protocol

  Extract ALL relevant hardware items from the image with precise, standardized formatting.

  ## Filtering Rules
  - **INCLUDE**: Physical hardware, modules, cables, servers, storage, transceivers
  - **EXCLUDE**: Generic mounting hardware (screws, brackets, rails), paper licenses, empty packaging
  - **Multi-item labels**: Treat each SKU/variant as a separate item (e.g., "5m cable" and "7m cable" = 2 items)

  ## Item Field Format (CRITICAL)
  Format: `<size_or_length> <type> <vendor> <connector> <part_number>`

  **Component Rules:**
  - `<size_or_length>`:
    - **STORAGE CAPACITY - HUMAN READABLE**: Convert to largest unit (TB/MB).
      - Examples: "1600GB" → "1.6TB", "256GB" → "256GB", "512MB" → "512MB"
      - Rule: If ≥1000GB, use TB. If ≥1000MB, use GB. Otherwise use MB.
    - **CABLE/WIRE LENGTH**: Meters only. Examples: "5m", "10m", "50m"
    - **RAM DIMM**: Capacity in GB. Examples: "128GB", "32GB", "8GB"
    - **SFP/TRANSCEIVER SPEED**: Speed in G/Mbps. Examples: "10G", "1G", "40G", "100G"

  - `<type>`: Asset class.
    - **CABLES**: 
      - Use "Fiber" for all optical fiber cables.
      - Use "Patchcord" for all copper UTP/RJ45 cables.
      - Others: SATA, SAS, Power, USB, etc.
    - **COMPONENTS**: DDR3/DDR4/DDR5, NVMe, SSD, HDD, SFP/Transceiver, DIMM, etc.
      - **PRECEDENCE**: If an item is both "SSD" and "NVMe", use **NVMe** as the type and category.

  - `<vendor>`: Manufacturer (HP, HPE, Dell, Samsung, Cisco, Hynix, Intel, Broadcom)
  - `<connector>`: Physical interface (RJ45, LC-LC, MPO, U.3, SATA, SAS, ST, SC). Omit if N/A.
  - `<part_number>`: Part number ONLY if visible. **Omit serial numbers.**

  **Item Examples (WITH HUMAN-READABLE SIZES):**
  - `1.6TB NVMe HPE U.3 P66093-002` (not 1600GB)
  - `256GB SSD Dell SATA SK-8765` (already human-readable)
  - `5m Fiber LC-LC` (optical cable)
  - `2m Patchcord RJ45` (copper cable)
  - `128GB DDR4 Hynix`
  - `10G SFP+ Cisco LC 10-2415-03`

  **Size Conversion Examples:**
  - 1600GB → 1.6TB
  - 2048GB → 2TB
  - 512GB → 512GB (under 1TB threshold)
  - 256MB → 256MB
  - 1024MB → 1GB

  **Restrictions:**
  - No comments in parenthesis
  - No measurement units in Item field (e.g., "1.6TB" not "1.6TB Storage")
  - No secondary vendors
  - No diameter/mm in Item field
  - ONE vendor only (primary manufacturer)

  ## Other Fields
  - **Type**: Repeat the asset class (DDR4, SSD, NVMe, Patchcord, etc.)
  - **Description**: Technical summary, max 5 words. Examples: "High-speed fiber optic", "Enterprise Gen4 storage"
  - **Category**: 
    - For Spare Parts (see below): Use `spare parts - <type>` where `<type>` is the lowercase component name (e.g., `spare parts - ram`, `spare parts - ssd`, `spare parts - nvme`, `spare parts - raid card`, `spare parts - cpu`, `spare parts - psu`, `spare parts - hba`, `spare parts - nic`, `spare parts - sfp`).
    - For Others: Use `Network`, `Cabling`, `Compute`, `Optical`, `Consumable`.
  - **Connector**: Interface type from Item field. Examples: "LC-LC", "RJ45", "U.3"
  - **Size**: **HUMAN-READABLE capacity, length, or speed.** Examples: "1.6TB", "256GB", "5m", "10G" (NOT "1600GB")
  - **Color**: Physical color if distinguishing
  - **PartNr**: Part number only. **CRITICAL: NEVER include Serial Numbers (S/N, SN, Serial).**
  - **Specs**: Detailed technical specifications (e.g., "1.2V, CL22", "850W 80+ Gold", "Gen4 x4", "Single-mode").
  - **OCR**: Robust matching key for OCR tolerance. Format: `TYPE SIZE VENDOR CONNECTOR PARTNUMBER` (UPPERCASE, no special chars).

  ## OCR Field Rules (CRITICAL)
  Generate a SHORT, clean matching key for database lookup:
  - Format: **UPPERCASE space-separated, NO special chars, NO duplicates**
  - Include ONLY: Type + Size + Primary Vendor + Connector + Part Number
  - **STRICT EXCLUSIONS**:
    - NO serial numbers (S/N, SN, Serial)
    - NO secondary vendor names
    - NO extraneous labels
  - **CONSTRAINTS**:
    - Each token appears ONE time only (no duplicates)
    - Remove hyphens/special chars for fuzzy matching (e.g., `SK-8765` -> `SK8765`)
  - **USE HUMAN-READABLE SIZE**: Use TB/GB/M/G from Item field.

  **OCR Examples:**
  - Item: `1.6TB NVMe HPE U.3 P66093-002` → OCR: `NVME 1.6TB HPE U3 P66093002`
  - Item: `5m Fiber LC-LC` → OCR: `FIBER 5M LC LC`
  - Item: `2m Patchcord RJ45` → OCR: `PATCHCORD 2M RJ45`
  - Item: `256GB SSD Samsung SAS SK-8765` → OCR: `SSD 256GB SAMSUNG SAS SK8765`
  - Item: `128GB DDR4 Hynix` → OCR: `DDR4 128GB HYNIX`
  - Item: `10G SFP+ Cisco LC 10-2415-03` → OCR: `SFP+ 10G CISCO LC 10241503`

  ## Spare-Parts vs Consumables Classification

  CLASSIFICATION GUIDE - SPARE PARTS vs CONSUMABLES:
  
  Spare Parts (replaceable components that plug into or interface with devices):
  - **RAM**: DDR3, DDR4, DDR5, SODIMM, DIMM → Category: `spare parts - ram`
  - **Storage**: NVMe, SSD, M.2, SATA HDD, SAS HDD → Category: `spare parts - nvme`, `spare parts - ssd`, or `spare parts - hdd`. 
    - *Rule: Use `nvme` if the item is an NVMe SSD.*
  - **CPU**: Processors, Intel Xeon, AMD EPYC → Category: `spare parts - cpu`
  - **Power**: PSU, Power Supply Modules → Category: `spare parts - psu`
  - **Controllers**: RAID Controllers, HBA, NIC, Network Cards → Category: `spare parts - raid card` or `spare parts - hba` or `spare parts - nic`
  - **Cooling**: Heatsinks, Fans (specific to models) → Category: `spare parts - cooling`
  - **Mainboard**: Motherboards, Riser Cards → Category: `spare parts - motherboard` or `spare parts - riser`
  - **Optical**: SFPs, Transceivers → Category: `spare parts - sfp`
  
  NOT Spare Parts (consumables, generic items):
  - Cables: Power cables, SATA cables, USB, Ethernet, Fiber Patchcords → Category: `Cabling` or `Consumable`
  - Fasteners: Screws, brackets, rails → Category: `Consumable`
  - Materials: Thermal paste, pads, tapes → Category: `Consumable`
  
  Decision Tree:
  1. Does the item have a manufacturer part number (P/N)?
  2. Is it a modular component of a larger system (Server, PC, Switch)?
  3. Does it have technical specs (Speed, Capacity, Voltage)?
  If YES to 2+ questions: Mark as `spare parts - <type>`
  If item is a cable: Mark as `Cabling`
  If item is a generic hardware: Mark as `Consumable`
  Otherwise: Mark as `uncertain` for review.
  
  Examples:
  ✓ "Kingston Fury 16GB DDR4-3200" → Category: `spare parts - ram`
  ✓ "Samsung 970 EVO 1TB NVMe" → Category: `spare parts - nvme`
  ✓ "Intel Core i7-12700K" → Category: `spare parts - cpu`
  ✓ "LSI MegaRAID 9361-8i" → Category: `spare parts - raid card`
  ✗ "6ft SATA Cable" → Category: `Cabling`
  ✗ "M3 Mounting Screws" → Category: `Consumable`
