MAC36 - PoE switches and MAC36

Introduction

Connecting MAC36 units, which do not support Power over Ethernet (PoE), to PoE switches can potentially lead to hardware damage if not properly managed. Understanding the type of PoE switch and its interaction with non-PoE devices is crucial to prevent equipment failure.

Good Practice

To ensure the safety and functionality of MAC36 units when interfacing with PoE switches, adhere to the following best practices:

1. Identify the Type of PoE Switch:

   • Active PoE Switches: These switches perform a handshake to determine if the connected device requires power. MAC36 units do not respond to this handshake, thus they do not receive power from active PoE switches, making them safe to use.

   • Passive PoE Switches: Unlike active switches, passive PoE switches do not perform a handshake and supply power regardless of whether the connected device can accept it. This can be harmful to devices like the MAC36 that are not designed to handle incoming power over Ethernet.

2. Use Appropriate Switch Settings or Equipment:

   • If using a passive PoE switch, ensure that the power injection on ports connected to MAC36 units is disabled. This prevents any accidental power supply that could damage the Ethernet ports of the MAC36.

   • Consider employing PoE splitters that can block unwanted power transmissions when using passive PoE switches.
