## Overview

The LINDY RJ45 Extension Kit includes 20 bright yellow port blockers designed to physically secure RJ-45 network ports. With a simple key-operated mechanism, it prevents unauthorized cable connections and protects network hardware from damage or tampering. Ideal for professional environments requiring quick, visible, and reliable port security.

## Description

With the LINDY RJ-45 Port Blocker, you can quickly block open network ports and easily prevent users from connecting cables, devices or inserting foreign objects without permission. This helps protect against unauthorized access to a network or system, as well as preventing unintentional or malicious damage to ports. It can also act as a visual cue, showing inactive or disconnected ports. To use, simply attach a blocker to the key and plug it into the port. Hold the blocker in place and pull away the Key. To remove, simply insert the Key back into the blocker until it 'clicks' and pull it away. Easy!

Review: Wir lassen gerade bauen und benötigen für die PV Anlage WLAN. Auch die Heizungsanlage soll in Kürze mit eingebundenen werden. Im Haus steht deshalb eine Fritzbox 7490 mit LTE Stick, welche per VPN mit dem Fritzchen in unserem aktuellen Zuhause verbunden ist. Leider ist es bei der 7490 nicht mehr möglich, die Ports abzuschalten (in der früheren Firmware konnte man das über die Energiespar-Einstellungen). Damit nicht irgend ein Monteur mal auf die Schnelle seinen Laptop anklemmt, sind diese Stöpsel drin. Leider nicht ganz billig, aber im heimischen LAN sind zwei NAS, bei denen nicht alle Inhalte Passwortgeschützt werden sollen bzw teilweise auch nicht können...
