Identifique su terminal POS IBM / Toshiba — Decodificador de números de modelo SurePOS y TCx

We process about 60 procurement enquiries a week. Roughly one in three arrives with the wrong machine type — "IBM 4810" instead of the specific 4810-340, "Toshiba TCxWave" with no variant, or a 12-year-old support sticker reading 4694-247 for a system that was actually swapped to a 4900-786 three years ago. Each mismatch costs the buyer a return-shipping cycle. This guide is the field reference that ends those mismatches.

The model number does three jobs at once: it identifies the cabinet, the year of manufacture (roughly), and the peripheral interface generation. Once you have it, every replacement part lookup — power supply FRU, riser card revision, thermal printhead resistance — falls into place. Without it, you're guessing.

Both IBM (1973–2012) and Toshiba TGCS (2012–present) use the same underlying naming scheme on retail POS hardware. It looks like this:

The 4-digit machine type is the broad family:

• 4610 — SureMark / TCx receipt & document printers (separate from the POS terminal itself)
• 4810 — SurePOS 300 class (low-cost retail register, 2003–2012)
• 4820 — SurePoint touch displays & integrated touch POS
• 4830 — POS keyboards (e.g. 4830-T01 ANPOS)
• 4838 — SurePOS 100 / 300-V (compact mid-class)
• 4840 — SurePOS 500 (mid-class)
• 4852 — SurePOS 500 / TCx 500 next-gen (touch all-in-one)
• 4900 — SurePOS 700 / TCx 700 (enterprise flagship)
• 6140 — TCxWave (all-in-one with curved bezel, 2014-present)

The suffix narrows the family down to one specific configuration: processor generation, power supply rating, expansion-slot layout, and peripheral interface set. Two terminals sharing a machine type but with different suffixes can have completely different mainboards.

Every IBM/Toshiba retail terminal ships with at least one factory label. The label has held the same six elements since 1996: machine type, model suffix, serial number, FRU of the chassis itself, MAC address, and a barcode of all of the above. Where you find the label depends on the chassis:

Below is the working catalog we use internally to map machine types to part categories. Treat the years as approximate — Toshiba extended support on most platforms 3–5 years past initial end-of-marketing.

The suffix letter sequence isn't random — it encodes specific configuration axes. The convention shifted slightly between the IBM and Toshiba eras, but the underlying mapping is consistent:

On August 16, 2012, Toshiba TEC acquired IBM's Retail Store Solutions business for $850 million. The deal transferred IBM's POS hardware portfolio — SurePOS, SureMark, SurePoint — and the 4690 operating system to Toshiba, which folded them into a new subsidiary, Toshiba Global Commerce Solutions (TGCS).

For the next 3–5 years, Toshiba continued shipping the same chassis with IBM-branded labels under a transitional licensing agreement. During this period a 4900-786 leaving the factory could carry either IBM or Toshiba branding depending on the buyer's contract — but the hardware is identical. By 2018 Toshiba completed the rebrand, renaming the SurePOS line to TCx (SurePOS 700 → TCx 700, SurePOS 500 → TCx 500), introducing the all-new TCxWave 6140 line, and retiring the IBM brand from new production.

The handful of exceptions: anything with a 7- or 8-character TGCS-era part number that starts with 00V, 54Y or 95Y is Toshiba-era stock (after 2014). Anything starting with 14R, 40N, 41J, 42M or 44V is IBM-era stock (2008–2014). Parts are forward- and backward-compatible at the chassis level.

The three-number system is the biggest source of confusion for first-time procurement. Each number identifies a different thing:

The screencast below walks through a real procurement workflow: a ticket lands describing "Toshiba TCx 6140-E3R, blank screen on boot, no fan noise." In under three minutes we narrow it from symptom to FRU to in-stock supplier match.

For the written equivalent: once you have a machine type and a symptom, the part falls into one of nine standard categories. The table below maps the most common failures to the part family you need to order:

Two follow-ups, in order:

1. Take photos of every label on the chassis before disassembly. The outer machine-type label, the inner FRU sticker, the power supply FRU, the riser card FRU. Save them in your ticketing system. Future maintenance becomes 10× faster when this data is on file.
2. Pull the part you need from a supplier with the FRU quoted on the listing. Generic descriptions ("IBM 4900 power supply") won't cut it — that term matches six different FRUs across the 4900 family. Match the FRU number digit-for-digit.
