Key Features
N9K-C9348GC-FXP provides 48 100M/1GBASE-T ports for copper-connected devices while keeping 4 SFP28 ports and 2 QSFP28 ports available for higher-speed fiber connectivity.
The 48 BASE-T ports fit server management, storage management, infrastructure appliance, and out-of-band access networks where connected devices require 100M or 1G copper rather than PoE.
The 4 SFP28 ports can be used for 1G, 10G, or 25G connectivity, giving engineers controlled uplink-speed flexibility without replacing the 1G copper access layer.
The 2 QSFP28 ports support 40G or 100G upstream connections, which helps keep a 1G copper access design from becoming isolated from faster aggregation or spine layers.
N9K-C9348GC-FXP is part of the Cisco Nexus 9300-FX series and supports NX-OS and ACI deployment models. Buyers should confirm minimum image, license, and operating mode before purchase.
The switch uses three fan modules and two power supply modules. Cisco requires airflow direction to match across fan and power modules, and AC/DC power sources should not be mixed.
Application Scenarios
Use N9K-C9348GC-FXP when a data center needs 48 copper ports for server management, appliance management, storage management, or infrastructure management interfaces, with 25G and 100G upstream options.
Choose this SKU when the project requires a Nexus data center switch rather than a campus access switch, but connected devices only need 100M or 1G copper downlinks.
Deploy N9K-C9348GC-FXP when most access-side devices remain on 1GBASE-T but the upstream network is moving toward 25G SFP28 or 40/100G QSFP28 connectivity. Confirm optics and cable support before quote.

- N9K-C9348GC-FXP fits Nexus 1G copper access when the design needs 48 BASE-T ports plus 25G and 100G uplink options.
- N9K-C9348GC-FX3 should be compared when the project can accept the newer 1G copper platform with a similar port layout.
- N9K-C93108TC-FX should be compared only when the access-side requirement is 10GBASE-T copper instead of 1GBASE-T.
- Review N9K-C93180YC-FX alongside N9K-C9348GC-FXP for the adjacent technical comparison points.
Selection Guide
1. Choose N9K-C9348GC-FXP for Nexus 1G copper access
Select N9K-C9348GC-FXP when the project needs 48 100M/1GBASE-T ports in a Cisco Nexus data center switch, plus 4 1/10/25G SFP28 ports and 2 40/100G QSFP28 uplinks.
2. Choose N9K-C9348GC-FX3 when newer platform resources are preferred
If the project is not locked to the FX platform, compare N9K-C9348GC-FX3 because it keeps a similar 1G copper access role while offering newer platform resources.
3. Choose N9K-C93108TC-FX for 10GBASE-T copper access
If connected servers or appliances require 10GBASE-T on the copper downlinks, N9K-C93108TC-FX is the closer comparison. Do not substitute N9K-C9348GC-FXP when 10GBASE-T downlink access is mandatory.
4. Verify optics, airflow, power, and licensing before quote
Before requesting price or stock, confirm SFP28 and QSFP28 optics or cables, airflow direction, 350W AC, 350W PHV/HVDC, or 440W DC power supply type, and the required NX-OS or ACI license.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Access Port Requirement |
100M/1GBASE-T copper access, not PoE and not 10GBASE-T |
Prevents ordering this SKU for the wrong endpoint requirement |
|
SFP28 Connectivity |
Cisco-supported SFP, SFP+, SFP28 optics, DAC, or AOC for 1G/10G/25G ports |
Ensures the 4 SFP28 ports match the intended link speeds |
|
QSFP28 Uplinks |
Cisco-supported QSFP28 optics, DAC, or AOC for 40G/100G uplinks |
Ensures upstream aggregation or spine links are ready |
|
Airflow Direction |
Port-side intake or port-side exhaust for fans and power supplies |
Mixed airflow can cause cooling problems |
|
Power Supply Type |
350W AC, 350W PHV/HVDC, or 440W DC power supply choice |
Power input and redundancy must match the rack design |
|
Power Supply Matching |
Do not mix AC and DC power sources or airflow directions |
Cisco installation guidance requires matching power and cooling design |
