With the Lindy SFP Port Blocker Key, the user can quickly block open SFP ports and easily prevent users from connecting cables, devices or inserting foreign objects without permission. This helps protect against unauthorised 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, ideal for use in schools, office or other public sector environments.
The semi-permanent SFP Port Blocker is made up of a moulded plastic blocking cap that plugs securely into the SFP port with a special insertion key. The blocker latches into the SFP just as a network cable would and remains in place until removed using the insertion key.
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.
Security Note: The Port Blockers will only act as a basic physical & visual deterrent to tampering. It will not prevent a determined attacker, intent on gaining physical access to a SFP port.
