What is the switching performance?

The switch delivers 328 Gbps switching capacity and 244 Mpps forwarding rate, enabling non-blocking wire-speed operation. This supports high-density Gigabit access with multi-gigabit uplinks for demanding enterprise workloads.

Does it support stacking?

Yes, via 2 x SFP-DD ports providing 80 Gbps stacking per unit, scalable to 8 switches. This creates a single logical unit for simplified management in Fabric Connect or ExtremeXOS environments.

MACsec is fully supported on all 24 access ports and 4 uplink ports, offering hardware-based 256-bit AES-GCM-128 encryption at line rate for secure edge-to-core links without performance impact.

What management options are available?

Features include 10/100/1000BASE-T OOB port, serial RJ-45 and USB Micro-B consoles, 2 x USB A for storage, front panel status LEDs, base software license, and 1-year XIQ Pilot subscription for cloud management.

What is the power and form factor?

1U fixed rackmount design with two unpopulated modular PSU slots (24W max system without PoE), one removable fan module. Dimensions suit standard 19-inch racks at 43.7mm H x 441mm W x 287mm D, weighing 4.18 kg.
