Does it support stacking?

Yes, with 2 dedicated 40Gb QSFP+ ports enabling SummitStack-V160 at 160Gbps full-duplex, stacking up to 8 X465/X590/X690 switches as a single logical unit. This supports high-speed, resilient fabrics with features like Priority Flow Control and Y.1731 OAM.

What are the performance specs?

Offers 364Gbps aggregated switch bandwidth, 517.9Mpps frame forwarding rate, 272K Layer 2 MAC addresses, 256K IPv4 LPM entries (ALPM), 128K IPv6 LPM, and 4096 VLANs. Supports 9216-byte jumbo frames and non-blocking wire-speed operation for high-density traffic.

What cooling and power options are included?

Includes 3 hot-swappable fan modules and 1 x 350W AC PSU (forward/back airflow). Operates 0-45°C, 10-95% humidity, up to 3000m altitude, with shock/vibration resilience, ensuring reliability in rack-mounted enterprise deployments.

Is MACsec supported on all ports?

Yes, all 48 x 10/100/1000Base-T ports are MACsec-capable per IEEE 802.1AE, plus modular uplink ports. This enables hardware-based link encryption for secure edge access without performance impact, ideal for protecting data in transit.

What OS powers the switch?

Powered by ExtremeXOS, offering advanced Layer 3 routing, VxLAN tunneling, MPLS/VPLS, SFlow telemetry, and integration with ExtremeCloud IQ for cloud management. Supports flexible UFT tables and up to 130K IP multicast (s,g) entries.
