# Connectivity and Networking

The Dell Pro Max GB10 provides extensive I/O for a system of its size, including high-speed networking for multi-unit configurations.

## 1. USB Ports

- **1x USB Type-C (20 Gbps)** — power input port (280W adapter connects here)
- **3x USB Type-C (20 Gbps)** — general purpose
- USB-C ports support **DisplayPort Alt Mode** for display output

## 2. Display Output

- **1x HDMI 2.1b** — dedicated display output
- **USB-C DisplayPort Alt Mode** — additional display(s) via USB-C

## 3. Wired Networking

- **1x 10 GbE Ethernet** (RJ45) — standard network connectivity
- **2x QSFP 200 Gbps ports** — via NVIDIA ConnectX-7 SmartNIC
  - Each port supports 200 Gbps
  - Primary use: [[multi-unit-stacking]] for scaling to 2-unit configurations
  - Based on ConnectX-7 SmartNIC technology

## 4. Wireless

- **Wi-Fi 7** (IEEE 802.11be)
- **Bluetooth 5.4**
