Frequently asked questions

What are the port specifications and fiber connectivity options for the 5520-48SE?

The 5520-48SE provides 48×100/1000BASE-X SFP ports for fiber connectivity, all MACsec-capable for Layer 2 security. Two QSFP28 universal ports support 40Gbps or 50Gbps stacking bandwidth for multi-switch deployments. One unpopulated VIM slot allows future modular expansion. All ports are unpopulated, requiring customer-supplied SFP transceivers for fiber optic connectivity.

How does the 5520-48SE support network stacking and high availability?

The dual QSFP28 stacking ports deliver 40Gbps or 50Gbps per port stacking bandwidth, enabling multiple 5520 switches to form a unified logical stack. This architecture provides redundancy, simplified management, and non-blocking fabric for east-west traffic between stacked units. Stacking data rates support both 40Gb and 50Gb configurations depending on deployment requirements.

What security features does the 5520-48SE provide for enterprise deployments?

All 48 SFP ports are MACsec-capable, enabling IEEE 802.1AE Media Access Control Security for Layer 2 encryption of sensitive traffic. MACsec protects against man-in-the-middle attacks and unauthorized access at the data link layer. Combined with ExtremeCloud IQ centralized management and Extreme Fabric Connect security provisioning, the 5520-48SE delivers comprehensive enterprise-grade network security.

Which operating systems and management platforms are supported?

The 5520-48SE features universal dual-persona hardware supporting both ExtremeXOS and ExtremeOS operating systems, providing flexibility for different network environments. Centralized cloud-based management is available through ExtremeCloud IQ and ExtremeCloud IQ Site Engine. Fabric-enabled operations leverage Extreme Fabric Connect for simplified provisioning, automation, and security policy enforcement across the network.

What expansion and modular capabilities does the 5520-48SE offer?

The switch includes one unpopulated VIM (Virtual Interface Module) slot for future modular expansion, enabling addition of specialized port types or functionality. The 5520-VIM-4YE module option adds four 10/25GBASE-X SFP28 ports for higher-speed uplink connectivity. This modular design allows the 5520-48SE to evolve with network requirements without complete hardware replacement.

How is the 5520-48SE managed and monitored in enterprise networks?

Management options include serial console port (RJ-45), USB Micro-B console port, and 10/100/1000BASE-T out-of-band management port for secure administrative access. Two USB Type-A ports support external USB flash for firmware updates and configuration backup. ExtremeCloud IQ provides centralized cloud-based monitoring, analytics, and policy management across distributed 5520 deployments.

What are typical deployment scenarios for the 5520-48SE in data center and campus networks?

The 5520-48SE excels as a data center interconnect switch for fiber-based multi-site connectivity with MACsec encryption, campus backbone aggregation consolidating multiple access layers, service provider edge switching with high SFP density, and fiber-to-building aggregation for large enterprise campuses. Its 48-port SFP architecture eliminates copper port overhead in fiber-native environments.
