Spectrum / SN2000 technical selection questions
These questions are prepared from the cited technical documentation and clearly scoped owner inputs. They are not a measured frequency ranking. Keep the applicability line with each answer; do not transfer board, cooling, crypto, protocol, cable length or firmware facts between variants.
What is the port configuration of MSN2410-CB2RC?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
The exact ordering row lists 48 SFP28 ports and eight QSFP28 ports, with 25GbE access and 100GbE uplinks. This is the Cumulus Linux, C2P configuration; BB2RC is a different speed variant and CB2R is an Onyx configuration.

Can SN2410 connect both 10GbE and 25GbE equipment?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
The hardware table supports 10/25GbE on ports 1–48. Select matching cable/transceiver types and configure both ends for the intended rate. A public forum discussion raises exactly this mixed-speed question, but its anecdotes do not establish automatic negotiation or universal third-party cable compatibility.

Does the CB2RC order code include unrestricted software use?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
The ordering description specifies Cumulus Linux and says a license key is required. Record the installed release and verify the applicable entitlement for the offered unit before planning installation or upgrades.

What does NVIDIA publish about SN2410-CB2RC lifecycle?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
The current ordering table marks this code EOL and states that the systems in that manual are no longer available for manufacturer ordering. That does not invalidate an owner-held product, but current condition, support and supply terms need separate confirmation.

Is there a documented RoCE application for SN2410?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
Yes. NVIDIA’s historical Spark 3.0/RAPIDS guide connects three nodes to an SN2410 with 25GbE DACs and documents RoCE configuration. Its illustrated BOM names MSN2410-CB2F, so it supplies family application context rather than proof of an exact CB2RC deployment.

Which facilities details matter for this SN2410 variant?
Applicable canonical content subjects: 920-9N112-00R7-0C2.
CB2RC specifies connector-to-power airflow, two AC supplies and a rail kit. The SN2410 manual gives a 394 mm chassis depth and 0–40°C operating range. Include connectors, cable bend radius, rack mounting and airflow clearance in the installation review.
