What is the maximum switching capacity and forwarding rate?

The X440-48t delivers 104 Gbps non-blocking switching capacity with 77 Mpps forwarding rate, enabling simultaneous line-rate performance across all 48 Gigabit ports. This ensures no congestion or bottlenecks even during peak traffic periods across the entire switch.

Can I stack multiple X440-48t switches together?

Yes. The X440-48t includes dual SummitStack ports supporting high-speed stacking of up to 8 switches into a single logical unit. This enables simplified management, automatic failover, and seamless bandwidth aggregation without requiring separate management interfaces or external stacking modules.

What uplink options are available?

The switch includes four 100/1000BASE-X SFP combo ports (unpopulated) that can accept optional fiber modules. Four of the 48 Gigabit ports are combo ports, allowing you to choose between copper or fiber connectivity. This flexibility supports diverse network topologies and distances.

Does this switch support redundant power supplies?

Yes. The X440-48t includes a redundant power supply connector, allowing installation of dual AC power supplies for N+1 redundancy. This ensures continuous operation during power supply failure or maintenance, critical for mission-critical network infrastructure.

What VLAN and trunk capabilities does it offer?

The switch supports 4,094 VLANs for comprehensive network segmentation and 128 load-sharing trunks with up to 8 members each. This enables multi-tenant isolation, departmental segmentation, and distributed bandwidth aggregation across multiple links for high-availability deployments.

What is the latency performance?

The X440-48t delivers sub-5 microsecond latency on 64-byte frames, ensuring minimal delay for time-sensitive applications like VoIP, video conferencing, and financial trading. This low-latency performance is maintained across the entire non-blocking architecture.

What management and security features are included?

The switch runs ExtremeXOS with modular architecture, EAPS resiliency protocol, and supports 1,024 ingress ACLs for granular access control. Eight QoS queues per port with 1,024 ingress bandwidth meters enable precise traffic prioritization and security policy enforcement without external appliances.
