N9K-C93180YC-FX3 Description
N9K-C93180YC-FX3 is a Cisco Nexus 9300-FX3 Series 1RU fixed-port data center switch with 48 1/10/25G SFP28 downlink ports and 6 fixed 40/100G QSFP28 uplink ports.
This SKU fits data center leaf, top-of-rack, and aggregation-access designs where servers, appliances, or storage-facing connections use SFP28 fiber or DAC/AOC cabling instead of RJ-45 copper. Network engineers usually compare it when they need Nexus NX-OS or ACI operation, 25G server access, and 40G/100G fabric uplinks in the same 1RU switch.
For procurement, quote N9K-C93180YC-FX3 with the required airflow direction, power supply type, rack kit, software mode, and transceiver or cable plan confirmed. It is not the right choice for copper 10GBASE-T access or PoE endpoint power.

Key Features
N9K-C93180YC-FX3 is built for racks where the access layer uses SFP28 optics, DAC, or AOC cabling instead of RJ-45 copper. It is a better fit than BASE-T models when server NICs and cabling are already fiber-based.
The 6 QSFP28 ports support 40G or 100G fabric connections, giving engineers enough uplink capacity for leaf-spine, aggregation, and migration designs without planning a separate uplink card.
This model can be evaluated for Cisco NX-OS environments or ACI deployments, with the final software mode and licensing confirmed against the project design before ordering.
Buyers considering a rack refresh can use N9K-C93180YC-FX3 when they want 25G server access and 100G uplinks in a newer Nexus 9300-FX3 hardware generation.
Cisco lists SyncE and PTP boundary clock support for the platform, which makes the switch relevant for telco data center edge designs where timing behavior must be part of the engineering review.
Power supplies and fan modules are field replaceable. Airflow direction must be matched across fans and power supplies so the switch aligns with the rack hot-aisle or cold-aisle plan.
Application Scenarios
Use N9K-C93180YC-FX3 when a data center leaf switch must connect servers or appliances through 1G, 10G, or 25G SFP28 ports. It fits teams that want Cisco Nexus operation and 100G-capable uplinks in a fixed 1RU form factor.
Choose this SKU when the rack is moving from older 10G fiber access toward 25G while keeping compatibility with 1G or 10G endpoints during migration. It solves the procurement problem of buying one model for mixed fiber speeds instead of separating 10G and 25G access layers.
Deploy N9K-C93180YC-FX3 when the access switch needs multiple QSFP28 uplinks into a spine, aggregation, or core layer. Before quoting, confirm the QSFP28 optics, DAC/AOC cables, airflow, and software release target.

- Choose N9K-C93180YC-FX3 when the project needs 48 ports of 1/10/25G SFP28 fiber access and six 40/100G QSFP28 uplinks.
- Choose N9K-C93108TC-FX3P only when the same rack needs RJ-45 multigigabit copper and PoE instead of SFP28 fiber.
- Choose N9K-C9348GC-FX3 when the access requirement is mainly 1G copper management with fewer high-speed uplinks.
Selection Guide
1. Choose N9K-C93180YC-FX3 for 25G SFP28 server access
Select N9K-C93180YC-FX3 when the connected devices use SFP28 optics, DAC, or AOC cabling and the rack needs 1G, 10G, and 25G access options. It is the direct choice for fiber-based Nexus leaf designs.
2. Choose a copper model when endpoints require RJ-45
If the devices use copper Ethernet ports, compare N9K-C93108TC-FX3P for multigigabit PoE copper or N9K-C93108TC-FX3 for non-PoE 10GBASE-T access. Do not substitute a fiber SFP28 switch unless NICs, optics, and cabling are changing.
3. Verify software mode and license requirements before ordering
Confirm whether the project will run Cisco NX-OS or ACI mode, and check the required feature set against Cisco licensing guidance. Some advanced functions may require additional software licenses.
4. Confirm airflow, power, rack kit, and optics before quote
For quote, price, stock, lead time, and global shipping checks, specify port-side intake or exhaust airflow, 650W AC / 930W DC / 1200W HVAC/HVDC power choice, rack installation kit, and the exact SFP28 or QSFP28 optics or cables needed.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Access Port Media |
SFP/SFP+/SFP28 optics, DAC, or AOC for ports 1 to 48 |
Prevents ordering a fiber switch for a rack that still needs RJ-45 copper |
|
Uplink Plan |
QSFP28 optics, DAC, or AOC for 40G or 100G links |
Ensures fabric, aggregation, or core links are ready at deployment |
|
Airflow Direction |
Port-side intake or port-side exhaust for fans and power supplies |
Mixed airflow can create cooling problems in production racks |
|
Power Supply Type |
650W AC, 930W DC, or 1200W HVAC/HVDC power supply option |
Site power design and redundancy depend on the selected PSU type |
|
Software Mode |
NX-OS or ACI deployment requirement and minimum release target |
Avoids mismatch between hardware, image, and intended operating model |
|
Rack Accessories |
1RU rack kit and any airflow sleeve requirement |
Helps avoid installation delay after hardware delivery |
|
Commercial Terms |
Price, stock, lead time, warranty handling, and global shipping destination |
Gives procurement a complete quote request instead of a partial model inquiry |
