## Overview

Before starting the GCXONE setup process, confirm that your network, browser, and device infrastructure meet the requirements below. Completing this checklist in advance prevents delays during onboarding and registration.

## Network Requirements

### Bandwidth

A minimum of 10 Mbps is required for standard platform operations. Video streaming and large data exports will require additional bandwidth depending on the number of active cameras and sites.

### Required Ports

The following ports must be open on your firewall before deployment:

- **443 (HTTPS/WSS):** Required for all web platform access, real-time WebSocket updates, REST API calls, and outbound webhooks. This is the primary port for GCXONE.
- **80 (HTTP):** Used for HTTP-to-HTTPS redirects. Optional but recommended to ensure smooth browser navigation.
- **161/UDP (SNMP):** Required for monitoring SNMP-enabled devices such as network equipment and power systems.
- **162/UDP (SNMP Trap):** Required to receive SNMP trap alerts from monitored devices.
- **502 (Modbus TCP):** Required for integrating industrial equipment and power systems using the Modbus protocol.
- **1883 / 8883 (MQTT):** Required for IoT device connectivity. Port 8883 is the encrypted variant and is preferred.

### DNS and Domain Access

Your network must be able to resolve and reach the nxgen.cloud domain. If you use internal DNS, add the appropriate A records or CNAME entries before deployment. Confirm this by running a DNS lookup from within your network before proceeding.

### Proxy Configuration

If your organization routes traffic through a proxy server, ensure the proxy is configured to allow WebSocket connections on port 443. Standard HTTP proxies may block WebSocket traffic, which is required for real-time alarm updates.

## Browser Requirements

GCXONE runs entirely in the browser. No software installation is required on operator workstations. The following browsers are supported:

- Google Chrome 90 or later (recommended)
- Microsoft Edge 90 or later
- Mozilla Firefox 88 or later
- Safari 14 or later

JavaScript must be enabled. A minimum screen resolution of 1920x1080 is recommended for full dashboard visibility.

## Account Requirements

Before your account can be activated, have the following ready:

- **Corporate email address:** Used for registration and receiving your activation email. Personal email addresses are not accepted.
- **Administrative access:** You will need permission to configure firewall rules and network settings during setup.
- **Primary and secondary contacts:** Required for account recovery and escalation. Both contacts should be reachable during the deployment window.

## Device and Site Preparation

If you plan to add cameras, sensors, or other devices during or immediately after setup, prepare the following in advance:

- **Device credentials:** Administrator usernames and passwords for all cameras and sensors to be integrated.
- **IP addresses and port numbers:** Document the IP address and communication port for each device.
- **Network topology:** Subnet details and gateway addresses for each site where devices will be deployed.
- **Device firmware:** Verify that all devices are running up-to-date firmware before integration to avoid compatibility issues.
