What is the port configuration and speed flexibility of Z9432F-ON?

Features 32x QSFP56-DD ports natively at 400GbE, breakout to 128x 100GbE or 144x 10/25/50GbE, plus 2x 1/10GbE SFP+ management ports. Multi-rate support includes 10/25/40/50/100GbE per port for seamless migration.

What switching performance does the Z9432F-ON provide?

Delivers 25.6Tbps full-duplex switching capacity and 5.2Bpps forwarding rate with sub-850ns latency. 132MB shared buffer and programmable NPU pipeline ensure wire-speed non-blocking performance under full load.

Which network operating systems are supported?

Open networking switch runs Dell SmartFabric OS10 Enterprise Edition or select third-party NOS like Cumulus, SONiC. Supports L2/L3 features including OSPF, BGP, VLT multipath, VXLAN, and DCB with PFC/ETS.

What power and environmental specs apply?

Dual redundant 1600W hot-swap AC PSUs, typical 900W consumption, max 1404W. Operates 0-45°C, 5-90% RH non-condensing; 7 fans (6+1 redundancy) with IO-to-PSU or reverse airflow options.

Is it suitable for spine-leaf data center topologies?

Yes, high-density 400GbE and 25.6Tbps capacity make it ideal for spine roles, aggregating leaf traffic with low latency, VLT for multipath, and PTP/Sync-E for precise timing in large-scale fabrics.

What management and timing features are included?

2x 1/10GbE SFP+ ports for out-of-band management, PTP/1588v2, Sync-E support. Intel Denverton C3758 8-core @2.2GHz CPU with 32GB DDR4 ECC handles up to 400K IPv4 routes.
