Juniper EX4100-F model decoder: what every part number means
Every EX4100-F part number encodes the port count, whether the switch delivers PoE, and whether it is a TAA-compliant variant. Once you can read the pattern, you never order the wrong model.
How the naming works
Example: EX4100-F-48P-TAA = EX4100-F series, 48 ports, PoE, TAA compliant.
| Part of the code | What it means |
|---|---|
| EX4100-F | The series — Juniper's compact, fanless-design campus access switch family (256 Gbps switching capacity). |
| 12 / 24 / 48 | Number of downlink ports on the front panel. |
| T | Data-only model — no Power over Ethernet on the downlink ports. |
| P | PoE model — downlink ports deliver Power over Ethernet for access points, phones and cameras. |
| -TAA | Trade Agreements Act compliant variant, for US public sector and government procurement. |

Common questions
- Which EX4100-F for wireless access points?
- A P model — the EX4100-F-24P or 48P depending on port count. APs draw power over Ethernet, so a T model would need separate injectors.
- Which models for US government or public sector?
- The -TAA variants: EX4100-F-24T-TAA, 24P-TAA, 48T-TAA and 48P-TAA. They are the TAA compliant versions required for many federal and public sector purchases.
- Is there a 12-port TAA model?
- Not in the official lineup — TAA variants start at 24 ports.
