# Front and Rear Panel Overview

## ARC Front Panel

ARC’s front panel features include:

- **Four status LEDs** indicating the status of each power supply (A, B), the **overall status** of the unit (C), and **sync** for the reference clock (D).
- A **color LCD display** to show status and basic configuration parameters (E)
- A **five-button navigation cluster** with Left, Right, Up, and Down arrows plus a green “OK” button (F)

Basic configuration and status monitoring can be performed using the front panel controls as outlined in the section on [Installation and Initial Setup](/v1/docs/arc-installation-and-initial-setup#front-panel-buttons). Connecting to ARC via the web-based user interface as outlined in the section on using the [Remote User Interface](/v1/docs/arc-remote-user-interface) provides easier navigation and full control of the unit.

## ARC Rear Panel

- One **SDI 3Gb/s HD/SD-SDI Input** (E) and **3Gb/s HD/SD-SDI Output** (D) on female BNC connectors
- Two RJ-45 **Gigabit Ethernet connections**, one for AES67 I/O (F) and one for network remote control (G)
- Two **IEC power inlets** for the internal redundant universal auto-ranging power supplies (H, I)
