Dell Fan Control

This script allows you to configure the fan speeds of multiple Dell servers using the IPMI tool. It prompts the user for server details and fan speed settings, and stores these settings for future use. I only have tested on R620's but this should work for other Dell servers as well.

Prerequisites

1. Download and Install IPMI Tool

   Download the IPMI tool from Dell and install it to the default path. You can download it from the following link:

   Dell IPMI Tool Download

2. PowerShell

   This script is written in PowerShell and requires a Windows environment with PowerShell installed.

Usage

First Time Setup

1. Clone or Download this Repository

   Ensure you have this script (DellR620FanScript.ps1) on your machine.

2. Run the Script

   Open a PowerShell terminal and navigate to the directory containing the script. Run the script with the following command:

   .\DellR620FanScript.ps1

Enter Server Details

The script will prompt you to enter the number of servers you want to configure. For each server, you will need to provide:

• IP Address
• Username
• Password
• Fan Speed (choose from the following options: Off, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%)

The fan speed options correspond to the following hexadecimal values:

• Off: 0x00
• 10%: 0x0A
• 20%: 0x14
• 30%: 0x1E
• 40%: 0x28
• 50%: 0x32
• 60%: 0x3C
• 70%: 0x46
• 80%: 0x50
• 90%: 0x5A
• 100%: 0x64

Configuration Storage

The script stores the entered server details and fan speed settings in a configuration file located in your user profile directory (serverConfig.json). This allows the script to reuse these details in future runs.

Subsequent Runs

1. Run the Script

   Run the script again with the same command: .\DellR620FanScript.ps1

2. Use Previous Configuration

   If a previous configuration is found, the script will ask if you want to use it. If you choose "yes", the script will proceed with the stored settings. If you choose "no", you will be prompted to enter new server details.
