Cisco Nexus 93128TX vs 93108TC-FX3
The Nexus 93128TX is an end-of-life high-density 10GBASE-T switch; the 93108TC-FX3 is its modern Cloud Scale 10GBASE-T replacement with 100G uplinks and a current ASIC. If you need copper 10GBASE-T top-of-rack and run 93128TX, the 93108TC-FX3 is the supported refresh that adds 100G uplinks and modern features.

Choose Cisco Nexus 93128TX if
Keep the 93128TX only if you specifically need 96 copper ports in one chassis as a short-term bridge. It is past support and capped at 40G uplinks.
Choose Cisco Nexus 93108TC-FX3 if
Choose the 93108TC-FX3 for the refresh: it keeps 10GBASE-T copper access but adds 100G uplinks, the Cloud Scale ASIC, NX-OS or ACI flexibility, and modern telemetry in a 1RU footprint. For 96-port density, deploy two 48-port units.
Verdict
Migrate from the Nexus 93128TX to the 93108TC-FX3. The 93128TX is end of life and limited to 40G uplinks on a legacy ASIC, while the 93108TC-FX3 keeps copper 10GBASE-T access, adds 100G uplinks, and runs Cloud Scale features. Note the port-count change: the 93108TC-FX3 is 48 ports, so high-density racks may use a pair.
Frequently asked questions
Is the Nexus 93128TX end of life?
Yes. The 93128TX has reached end of sale and end of support. The Cloud Scale 93108TC-FX3 is the current 10GBASE-T replacement.
Does the 93108TC-FX3 keep copper 10GBASE-T like the 93128TX?
Yes. The 93108TC-FX3 provides 48 100M/1G/10GBASE-T RJ45 copper ports, so it suits the same copper-server top-of-rack role as the 93128TX.
Why does the replacement have fewer ports?
The 93128TX is a 96-port 3RU switch; the 93108TC-FX3 is a 48-port 1RU switch. For 96 copper ports you typically deploy two 93108TC-FX3 units, gaining 100G uplinks and redundancy.
Does the 93108TC-FX3 support 100G uplinks?
Yes. It offers six QSFP28 uplinks that can run 40G or 100G, a significant step up from the 93128TX's 40G QSFP+ uplinks.
