What are the uplink and stacking options?

The switch provides 4 x unpopulated 1/10/25Gb SFP28 uplink ports and 2 x unpopulated stacking/SFP-DD ports. Stacking supports up to eight units at 80Gb per unit via qualified SFP+/SFP-DD cables when running Switch Engine OS, ideal for scalable edge aggregation.

Is MACsec supported, and on which ports?

Yes, all 48 Ethernet ports are MACsec-capable for hardware-accelerated link encryption, plus MACsec on uplink ports. This ensures secure, standards-based protection against eavesdropping in enterprise access layers without performance impact.

What power and cooling features are included?

Two field-replaceable PSU slots accept 2000W AC PoE units (e.g., XN-ACPWR-2000W, front-to-back). Min power is 72W (245 BTU/hr), max 3090W (716 BTU/hr excluding PoE load). Includes 1 x removable fan module (XN-FAN-000) for modular maintenance.

What management interfaces are available?

Features 1 x 10/100/1000BASE-T out-of-band management port, 1 x RJ-45 serial console, 1 x USB Micro-B console, and 2 x USB-A ports for management or external flash. Base license includes 1-year XIQ Pilot for cloud-based monitoring.

What is the switching performance?

Offers 376 Gbps switching capacity and 315.5 Mpps forwarding rate in a non-blocking architecture. Supports full/half-duplex autosensing on Gigabit ports, ensuring wire-speed performance for dense edge traffic in enterprise networks.
