Cisco N55-M16UP 16-Port 10GE Ethernet/FCoE Expansion Module

The Cisco N55-M16UP is a 16-port 10 Gigabit Ethernet expansion module designed for Cisco Nexus 5500 Series switches. This unified port module provides sixteen high-speed 10GE ports that support both Ethernet and Fibre Channel over Ethernet (FCoE), allowing flexible deployment in modern data center environments. The module enables network administrators to use the same physical ports for traditional Ethernet networking or converged storage networking, helping organizations simplify infrastructure and reduce hardware complexity.The N55-M16UP integrates seamlessly with compatible Cisco Nexus 5500 platforms and supports Small Form-Factor Pluggable Plus (SFP+) transceivers for high-performance fiber connectivity. Its unified port architecture allows administrators to configure ports individually as Ethernet or FCoE depending on application requirements, making it suitable for environments that require both high-speed data networking and storage connectivity. This flexibility helps optimize data center designs by consolidating LAN and SAN traffic onto a single network infrastructure.
With support for advanced Cisco NX-OS features, the module enables data center operators to implement sophisticated networking capabilities such as virtualization support, traffic prioritization, quality of service (QoS), and enhanced security policies. The modular design allows quick installation into Nexus 5500 Series switches, enabling easy network expansion and increased port density while maintaining reliable high-throughput performance for enterprise and cloud data center deployments.
