Port blocker set MOXA SFP Port Locks Green — 10 pieces with 1 key, compatible with SFP ports

MOXA SFP Port Locks Green — pack of 10 port blockers with 1 removal/installation key, designed for standard SFP transceiver ports. These green port locks plug into unused SFP slots to provide a simple physical barrier that prevents unauthorized cable insertion and protects transceiver contacts from dust and accidental damage. The set is intended for controlled environments such as data centers, telecom racks, network cabinets and other installations where managing access to optical and copper SFP interfaces is required.

Advantages

The MOXA SFP Port Locks are moulded plastic blockers that latch into the SFP port in the same way as an SFP connector, providing a secure fit until removed with the supplied key. A single key installs and removes all blockers, which streamlines port management and maintenance. The green colour offers a visible indication of blocked or inactive ports, aiding inventory and access control procedures without modifying network hardware.

Suitable for

• Data centres and server rooms where unused SFP ports should be physically blocked
• Network cabinets and patch panels to prevent accidental cable insertion
• Telecom and industrial network equipment maintenance to protect transceiver slots
• Public environments such as schools and offices where visual access control is useful

When it may not be suitable

These port locks act as a basic physical and visual deterrent; they are not a replacement for electronic access controls or full physical security measures. They will not prevent a determined attacker from gaining access to a SFP port if forceful tampering or specialised tools are used.

Key specifications

• Quantity: 10 port blockers and 1 installation/removal key
• Compatibility: designed for standard SFP transceiver ports
• Material: moulded plastic blocking cap with keyed insertion/removal mechanism
• Colour: green for visual identification of blocked ports

How to use

To install a blocker, attach the blocker onto the supplied key and insert it into the SFP port until it latches. Hold the blocker in place and withdraw the key; the blocker will remain seated in the port. To remove a blocker, insert the key into the blocker until an audible or tactile click indicates engagement, then pull the blocker out using the key. The same key is used for all blockers in the pack.

What to consider before purchase

• Ensure your devices use standard SFP transceiver slots; these blockers are not guaranteed for non-standard or proprietary port shapes
• Assess whether a visual/basic physical deterrent meets your security requirements or whether stronger physical controls are needed
• Consider the desired blocker colour for inventory or access-control identification

Usage recommendations

Use the port blockers to mark and protect unused SFP ports during maintenance windows and in public access areas. Store the key in a secure location to control who can remove blockers, and routinely inspect blocked ports for proper seating and cleanliness.
