Silver 2U rack-mount network switch with 64 QSFP56-DD ports and dual hot-swap power supplies

DELL

DELL Z9664F-ON 64P 400GbE QSFP56-DD network switch

SKU CH-C9PM-A3Q54 MPN Z9664F-ON

A 2 RU switch with 64 x 400GbE QSFP56-DD ports, 2 x 1/10GbE SFP+ uplinks, RJ-45 and USB management, OS10 Enterprise, dual 2400W PSUs and four hot-swap fans

  • 64 ports deliver 400GbE throughput for high-density networking
  • 2 RU form factor fits standard rack deployments
  • OS10 Enterprise perpetual license provides full switching features
  • Dual hot-swappable 2400W PSUs ensure continuous power availability
  • Four hot-swappable reverse-airflow fans maintain optimal cooling

High-density 400GbE switching platform

The Dell Networking Z9664F-ON delivers 64 ports of 400GbE QSFP56-DD connectivity in a 2 RU form factor. It runs OS10 Enterprise with a perpetual licence and includes two hot-swappable 2400W AC reverse-airflow power supplies plus four matching fans. Management is handled through a dedicated RJ-45 console port, a 10/100/1000 Ethernet port, USB 3.0 Type-A and USB-C interfaces.

Suited for large-scale spine and leaf fabrics

Data-centre operators building high-throughput leaf-spine topologies will match the 64-port density and 400GbE line rate. The reverse airflow design (PSU-to-I/O) fits cold-aisle containment layouts. Buyers needing lower port counts, slower uplink speeds or front-to-rear cooling should evaluate other platforms.

64 x 400GbE QSFP56-DD port count

The single specification that determines fit is the 64-port 400GbE QSFP56-DD complement. If the design calls for exactly this port density and transceiver interface at 400GbE line rate, the switch meets the requirement; any deviation in port quantity or speed means a different model is needed.

Questions about this item

What rack height does the 2 RU chassis require?

The switch occupies 2 RU of vertical space in a standard rack cabinet.

How are the hot-swappable PSUs and fans installed, and what is the common mistake?

Slide each 2400 W AC PSU and each reverse-airflow fan into its bay until the latch clicks; the step often missed is confirming the PSU-to-I/O airflow direction matches the rack cooling plan.

Which field-replaceable components will need attention over time?

The two hot-swappable 2400 W AC PSUs and the four hot-swappable reverse-airflow fans are the only user-serviceable parts designed for in-service replacement.
