Smart PDU with 4 metered & switched IEC C13 power outputs
Protect Critical SFP Ports from Tampering, Damage or Unauthorised Access
The Lindy SFP Port Blocker provides a fast, effective way to physically secure unused SFP (Small Form-factor Pluggable) network ports. These compact blockers are ideal for safeguarding fibre infrastructure in sensitive IT environments, AV-over-IP setups, and networked installations where access control is essential.
By preventing unauthorised connections, accidental cable insertions or foreign object intrusion, Lindy SFP Port Blockers reduce the risk of port damage and potential downtime. A robust insertion mechanism keeps each blocker firmly in place, with colour-coded keys ensuring only authorised removal. Additional keys and blocker packs are also available.
Physical Network Access Control
Blocks unauthorised SFP port use and deters accidental cable insertion
Fibre-Ready Protection
Ideal for delicate SFP connections in enterprise and AV-over-IP systems
Quick Installation
Tool-free deployment – install or remove in seconds
Visual Cue
Indicates unused ports or identifies disconnected endpoints
Low Cost, High Scalability
Ideal for large rollouts with minimal overhead
Latching Design
Mimics the clip action of real connectors – for a secure hold
Data Centres & Enterprise Network
Protect switchgear, routers and critical optical interfaces from disruption.
Education & Public Sector
Prevent tampering with fibre links in classrooms, libraries and shared facilities.
Retail & Hospitality AV Installations
Secure fibre-based AV equipment and signage systems in publicly accessible locations.
Facilities / Infrastructure
Visually mark inactive ports for future provisioning
Libraries / Shared Workspaces
Block unauthorised connections in public computing environments.
Healthcare & Labs
Protect equipment in clinical environments from unauthorised connections.
Lindy SFP Port Blockers deliver precise physical control over fibre ports, helping IT and AV professionals reduce risk and maintain infrastructure integrity. Easy to deploy, visually obvious and highly scalable, they’re the smart choice for any network where protection starts at the port.

The Lindy 4 Port IPower Switch provides secure remote switching, rebooting and monitoring for up to four connected devices, making it ideal for IT, AV and industrial environments where reliable power management is essential.
Designed to reduce downtime and simplify maintenance, the 4 Port IPower Switch allows administrators and installers to remotely power connected devices on or off, perform reboots, monitor energy usage and apply controlled sequencing after outages or resets. This makes it ideal for installations where access is limited, service response needs to be faster, or equipment uptime is critical.
4x IEC C13 switched outputs
Independent control for connected devices.
Web GUI, RS-232 and open API control
Flexible integration into managed systems.
Monitoring and alert functions
Track voltage, current and consumption.
Dual redundant Ethernet ports
Reliable network connectivity for critical systems.
Independent power control for up to four devices
Each
outlet can be switched individually, allowing precise power-on,
power-off and reboot functions without disrupting the rest of the
installation.
Remote access with flexible control options
Manage
the switch via a user-friendly web interface, RS-232 or supported
protocols including Telnet, Modbus TCP, SSH, SNMP and MQTT.
Real-time monitoring and proactive alerts
Monitor
voltage, current and power consumption, while email notifications
provide alerts and reports for overload and overcurrent events.
Reliable sequencing and scheduling
Configurable
power-on and power-off delays help protect equipment during restarts
and enable structured recovery after a power loss.
Built for professional environments
A
robust metal housing, manual outlet buttons, status LEDs and redundant
Ethernet connectivity make it well suited to demanding installations.
Reduced downtime and easier maintenance
By
allowing remote reboot and controlled power management, the switch
helps reduce manual intervention and improves serviceability for
difficult-to-access equipment.
The 4 Port IPower Switch is ideal for remote management of servers, network switches, routers, control processors, digital signage players, AV systems and other critical devices. It is particularly well suited to comms rooms, meeting spaces, education installations, industrial control environments and other locations where remote rebooting, outlet monitoring and controlled power sequencing can reduce downtime and simplify support.
The Lindy 4 Port IPower Switch features one IEC C14 power input, four IEC C13 10A switched outputs, dual redundant RJ45 Ethernet ports and RS-232 control via a 3-pin phoenix connection. It supports input voltages from 110–250V with a total switched power of up to 2500W, or up to 2640W when the voltage threshold is configured accordingly.
Additional features include scheduling, power-off memory, overcurrent and overvoltage protection, plus support for professional control protocols. Supplied with mounting brackets, an RS-232 cable, UK and Schuko power cables, and backed by a 3-year warranty.
