210-AHMT - Dell PowerSwitch S4048T-ON 48-Port 10GbE Switch

Dell PowerSwitch S4048T-ON 48-port 10GBase-T Layer 3 managed switch with 6x 40GbE QSFP+ uplinks for high-density, low-latency top-of-rack data center connectivity.

The Dell 210-AHMT is the Manufacturer Part Number for the Dell EMC PowerSwitch S4048T-ON, a high-density top-of-rack data center switch purpose-built for high-performance computing and virtualized environments. It provides 48 fixed 100M/1G/10G dual-speed 10GBase-T (RJ-45) ports for direct copper server connections plus six fixed 40GbE QSFP+ uplink ports, each capable of breaking out into four 10GbE ports for added flexibility. The switch runs on a non-blocking switching fabric offering line-rate Layer 2 and Layer 3 forwarding, and supports the Open Network Install Environment (ONIE) for zero-touch deployment of Dell EMC Networking OS9 or SmartFabric OS10. It ships in a standard 1U rack-mountable chassis with dual hot-swappable AC power supplies and four removable fan modules, and is intended for enterprise, service-provider, and data-center top-of-rack deployments requiring dense 10G copper connectivity with 40G uplink aggregation.
