The blocker latches into the RJ-45 just as a network cable would & remains in place until removed using the insertion key.\n To use simply attach a blocker to the key & plug it into the port. Hold the blocker in place & pull away the Key. To remove simply insert the Key back into the blocker until it &152;clicks&153; & pull it away. Easy!\n Security Note: This Port Blocker will only act as a a basic physical & visual deterrent to tampering. It will not prevent a determined attacker intent on gaining physical access to a RJ-45 port. Features USB Type USB Blockers & Switches
