SN2201 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.
What is the specified configuration of MSN2201-CBARC?
Applicable catalog candidates: 920-9N110-00R1-AC0.
Documentation scope: Exact owner-confirmed product; any held field is explicitly identified in this record.
NVIDIA Spectrum based 1GbE/100GbE 1U Open Ethernet switch with Cumulus Linux, 48 RJ45 ports and 4 QSFP28 ports, Dual Power Supplies (DC), x86 CPU, Connector-to-Power airflow.
Public references: PNY NVIDIA Networking Product Range, May 2025.
Where is SN2201 used in NVIDIA reference designs?
Applicable catalog candidates: 920-9N110-00R1-AC0.
Documentation scope: Family-level manufacturer reference design, not customer deployment.
NVIDIA’s SuperPOD reference architectures use SN2201 for out-of-band management of compute, switch, server, storage and rack-management interfaces. The B300 XDR network-fabric guide explicitly discusses AC or DC SN2201 systems; it does not identify CBARC as the exact installed OPN.
Public references: DGX B300 SuperPOD XDR Reference Architecture, Network Fabrics, DGX B200 SuperPOD Reference Architecture, Network Fabrics.
Is the SN2201 rail kit also the SN2201_M kit?
Applicable catalog candidates: 920-9N110-00R1-AC0.
Documentation scope: SN2201 and SN2201_M rail selection.
The SN2201 manual lists different kits: MTEF-KIT-M-TL for SN2201 and MTEF-KIT-MX-TL for SN2201_M in MGX racks. Keep those order codes distinct.
Public references: Accessory and Replacement Parts | SN2201 and SN2201_M 1G Management Switch Systems User Manual.
What do P2C and C2P mean?
Applicable catalog candidates: 920-9N110-00R1-AC0.
Documentation scope: Air-cooled switch systems and their documented fans or PSUs.
P2C moves air from the power side toward the connectors. C2P moves air from the connectors toward the power side. Select the direction specified for the exact switch configuration.

Does a public ordering or compatibility entry prove stock and delivery?
Applicable catalog candidates: 920-9N110-00R1-AC0, 930-9BRKT-0064-000.
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.

What is the specified configuration of MTEF-KIT-ADCT-A?
Applicable catalog candidates: 930-9BRKT-0064-000.
Documentation scope: Exact owner-confirmed product; any held field is explicitly identified in this record.
Airduct for SN2201, switch airflow extender.
Can I select a replacement by appearance or wattage alone?
Applicable catalog candidates: 930-9BRKT-0064-000.
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.
Public references: Accessory and Replacement Parts | NVIDIA Spectrum-3 SN4000 1U and 2U Switch Systems Hardware User Manual, Accessory and Replacement Parts | NVIDIA Spectrum-4 SN5000 2U Switch Systems Hardware User Manual.
Where should I check the replacement procedure?
Applicable catalog candidates: 930-9BRKT-0064-000.
Documentation scope: family-level; exact compatibility not implied.
Use the hardware manual for the exact chassis and component. Treat the replacement-parts list as ordering guidance; it does not replace the installation, airflow and safety instructions.
