Adapter module EXTREME X450-G2 MACSEC LRM Adapter (MPN 16779) for X450-G2 switches — MACsec support, LRM multimode fibre

The EXTREME X450-G2 MACSEC LRM Adapter is a plug-in module for EXTREME X450-G2 switches that adds IEEE 802.1AE MACsec Layer 2 encryption and LRM multimode fibre connectivity. Designed to fit the module slot of compatible X450-G2 platforms, this adapter enables encrypted traffic over multimode optical links while supporting extended reach compared with standard multimode transceivers. It provides a way to add secure Layer 2 links to campus and data centre networks without replacing existing switch hardware.

Advantages

The adapter delivers hardware-based MACsec encryption at Layer 2, reducing the need for additional security appliances and ensuring low-latency protected links. Its LRM multimode fibre support permits longer multimode runs, helping to bridge distances common in enterprise and campus environments. The module is hot-pluggable into supported X450-G2 chassis, which simplifies upgrades and deployment. Combined with the switch software, it allows centralized policy and key management for secure connectivity.

Suitable for

• Secure link encryption between access, aggregation and core switches in campus networks
• Encrypted connections in data centre topologies where Layer 2 security is required
• Extending multimode fibre links between buildings or within large facilities
• Upgrading existing X450-G2 installations to support MACsec without replacing the switch

Key specifications

• Function: MACsec Layer 2 encryption module with optical transceiver
• Optical type: LRM multimode fibre support for extended multimode distances
• Compatibility: Designed for EXTREME X450-G2 series modular slots
• Form factor: Plug-in adapter module, hot-pluggable in supported chassis
• Latency: Hardware-based encryption to minimize forwarding delay

How to use

Install the adapter into an available module slot of a compatible X450-G2 switch following the switch hardware installation procedure and safety guidelines. Configure MACsec through the switch management interface or network management system to enable encryption policies, key exchange and association with the appropriate ports. Connect LRM multimode fibre cabling to the adapter’s optical ports using matching multimode patch cords and verify the link status and negotiated MACsec session on the switch.

Usage recommendations

Use multimode fibre cable types and patch cords rated for LRM operation and maintain clean connector end-faces. Ensure switch firmware and network management software support MACsec features and key management for proper operation. For distances approaching LRM limits, test links under expected conditions and verify throughput and latency to confirm performance meets deployment requirements.
