What are the port configurations and maximum active ports on 5520-24X-BASE?

The 5520-24X-BASE features 24x 1/10Gb SFP+ ports plus 2x QSFP28 stacking/uplink ports channelizable to 8x10Gb SFP+ or 4x25Gb SFP28, supporting max 36x10Gb SFP+, 12x25Gb SFP28, 2x40Gb QSFP+, or 4x50Gb ports for flexible high-speed connectivity in edge/aggregation roles.

What switching performance does the 5520-24X-BASE provide?

It delivers 1080Gbps full-duplex aggregated bandwidth and 803.5mpps forwarding rate, ensuring non-blocking wire-speed operation across all ports, ideal for high-density 10/25G traffic in data centers or campuses with low-latency east-west flows.

Does it support stacking and what are the scaling limits?

Yes, up to 8 units stack at 160Gbps using 2x40Gb stacking ports on QSFP28. Scaling includes 40,000 IPv6 routes/8,000 shared, 4,094 VLANs, 9,216 ingress ACLs, and 8 QoS queues per port for demanding enterprise fabrics.

What management and OS options are available?

Universal hardware runs ExtremeXOS (EXOS) or VOSS with dual-persona support. Managed via ExtremeCloud IQ cloud/public/private or Site Engine on-premises; includes 1-year ExtremeCloud IQ Pilot subscription for simplified, secure operations.

What security and fabric features does it offer?

MACsec on access/uplink ports provides link encryption. Extreme Fabric Connect enables L2/L3 VSNs (3500 L2/256 L3), automated provisioning, secure segmentation; supports policy profiles up to 8,120 rules and 9,216 authenticated users.

What are the physical dimensions and redundancy options?

1U chassis measures 17.4x1.7x17.4in (441x44x442mm) without PSU, 18.1in depth with PSU. Features hot-swappable redundant power supplies, fans, front-to-back/back-to-front airflow, and 1x VIM slot for expansion.
