# FHS Specification Sheet
Last Updated: 2026-02-23
Onyx Front Haul Switch
The GXC Onyx Fronthaul Switch (FHS) is a high-performance, versatile open networking device designed to address the needs of fronthaul transport requirements of 5G architectures by:
* Future-proofing for 5G with ultra-low forwarding latency, high precision
* frequency and phase timing synchronizations
* Supports 10/25/40/100/200/400Gbps
* Switching capacity for up to 40 SFP+ ports at 10 Gbps
* Hot swappable power supplies with 1+1 redundancy support
* Hot swappable fan modules with 4+1 redundancy support
* Supporting full SyncE and IEEE 1558 v2 (T-GM, T-BC/OC, T-TC)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.gxc.io/hw/5g/5g-fronthaul-switch/fhs-specification-sheet.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
