SN6800-LD technical selection Q&A
Owner-confirmed and documentation-backed questions with explicit variant applicability and source boundaries.

These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.
The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.
Is SN6600 the same configuration as SN6600-LD?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: SN6600 family selection.
No. The manual distinguishes air-cooled, AC-powered SN6600 from liquid-cooled, DC-busbar SN6600-LD. Keep full model names and ordering codes separate in designs and case-study claims.

Which listed Spectrum-6 systems use co-packaged optics?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: SN6600 / SN6810-LD / SN6800-LD.
The ordering table identifies SN6810-LD and SN6800-LD as CPO systems. SN6600 instead lists OSFP cages. Their optical and infrastructure designs should not be treated as interchangeable.

Can I select a replacement by appearance or wattage alone?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: family-level; exact compatibility not implied.
Use the manufacturer replacement-parts table for the complete switch model and order code. Matching dimensions, connector shape or PSU wattage alone does not establish compatibility.

Does a public ordering or compatibility entry prove stock and delivery?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: Editorial procurement boundary; no promised availability.
No. Record the manufacturer’s published lifecycle wording separately from commercial availability. Stock, lead time, software entitlement, support and warranty require a current supplier quote.

Why is the connector wording held for SN6810-LD and SN6800-LD?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: SN6810-LD / SN6800-LD; unresolved official-source inconsistency.
The reviewed Spectrum-6 hardware manual uses MMC-16, while NVIDIA’s Ethernet-switching marketing table uses MMC-12. The product identity is documented, but the connector field needs manufacturer clarification before cable selection.

Is an external laser source a conventional pluggable transceiver?
Applicable catalog candidates: 920-9N67K-00LA-GC0.
Documentation scope: Documented CPO/ELS systems only.
NVIDIA documents ELS components separately for its photonics switch systems. Use the switch-specific ELS order code and service procedure; a conventional OSFP transceiver is not established as a substitute.
