N9K-C93108TC-FX3P Description
N9K-C93108TC-FX3P is a Cisco Nexus 9300-FX3 Series 1RU fixed-port data center switch with 48 100M/1/2.5/5/10GBASE-T PoE-capable ports and six 40/100G QSFP28 uplink ports.
This SKU is the copper and powered-endpoint option in the 93108TC FX3 family. Compared with N9K-C93108TC-FX3, it adds 2.5G and 5G Base-T speeds plus PoE on ports 1 to 48; compared with N9K-C93180YC-FX3, it serves RJ-45 copper access instead of 1/10/25G SFP28 fiber access.
For purchase review, confirm the intended NX-OS or ACI mode, airflow direction, PoE power budget, power-supply plan, QSFP28 optic or cable support, and any software license needs before the hardware is added to a quote.

Product Performance
Key Features
The 48 copper ports support 100M, 1G, 2.5G, 5G, and 10GBASE-T, so the same switch can serve mixed-speed copper devices that also need PoE.
The six QSFP28 ports support 40G or 100G links for spine, aggregation, or core connectivity without an added uplink module.
The model belongs to the Cisco Nexus 9300-FX3 Series, giving buyers a current FX3 platform option for copper access designs.
Cisco documentation covers the switch in NX-OS and ACI mode, so the operating mode and minimum release must be tied to the deployment plan.
The chassis uses four fan modules and up to two power supplies; the ordered parts must match the rack airflow direction.
PoE capacity changes by 1900W or 1100W power supplies and by redundant or nonredundant mode, so powered-device counts should be checked before purchase approval.
Application Scenarios
Use N9K-C93108TC-FX3P when the rack access layer needs RJ-45 copper ports for devices running at mixed 100M, 1G, 2.5G, 5G, and 10G speeds while staying on a Nexus data center switch.
Select this SKU when the connected endpoints require PoE from ports 1 to 48 and the design still needs six QSFP28 uplinks into a 40G or 100G fabric.
Choose this model when N9K-C93108TC-FX3 is too limited because it lacks 2.5G, 5G, and PoE, or when N9K-C93180YC-FX3 does not match the copper cabling plan.

- In a N9K-C93108TC-FX3P vs N9K-C93108TC-FX3 comparison, the main difference is that N9K-C93108TC-FX3P adds 2.5G and 5G Base-T speeds plus PoE on the copper access ports.
- The N9K-C93108TC-FX3P vs N9K-C93180YC-FX3 difference is access media: N9K-C93108TC-FX3P is the multigigabit RJ-45 PoE option, while N9K-C93180YC-FX3 is the 1/10/25G SFP28 fiber option.
- For a N9K-C93108TC-FX3P vs N9K-C9348GC-FX3PH comparison, check copper speed and uplink layout: N9K-C93108TC-FX3P gives 48 100M-to-10G Base-T ports and six QSFP28 ports, while N9K-C9348GC-FX3PH focuses on lower-speed copper with four SFP28 and two QSFP28 ports.
- Buyers deciding which model to choose should match the cabling type, powered-device requirement, downlink speed, and QSFP28 uplink count shown in the table.
Selection Guide
1. Choose N9K-C93108TC-FX3P for mGig copper with PoE
Select this SKU when the BOM requires 48 RJ-45 ports that can cover 100M, 1G, 2.5G, 5G, and 10G access plus PoE on those access ports.
2. Use N9K-C93108TC-FX3 for non-PoE 10GBASE-T access
Compare N9K-C93108TC-FX3 only when 2.5G, 5G, and access-side PoE are not part of the design requirement.
3. Use N9K-C93180YC-FX3 for SFP28 fiber access
Move to N9K-C93180YC-FX3 when servers or appliances use 1/10/25G SFP28 optics, DAC, or AOC cabling instead of RJ-45 copper.
4. Verify operating mode and power before final approval
Confirm NX-OS or ACI mode, minimum release, airflow direction, PSU selection, redundancy mode, and QSFP28 media before finalizing the quote scope.
