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.

Q: What is the Dell 210-AHMT part number for?

A: 210-AHMT is the Dell manufacturer part number for the PowerSwitch S4048T-ON, a 48-port 10GBase-T Layer 3 managed switch with 6x 40GbE QSFP+ uplinks and standard I/O-to-PSU airflow.

Q: How many ports does the S4048T-ON (210-AHMT) have?

A: It has 48 fixed 10GBase-T RJ-45 ports supporting 100M/1G/10G speeds, plus 6 fixed 40GbE QSFP+ uplink ports that can break out into 4x10G each.

Q: What is the switching capacity and forwarding rate of this switch?

A: According to third-party specification listings, the switch offers a switching capacity of up to 1.44 Tbps full-duplex and a forwarding rate of 1080 Mpps.

Q: Which operating systems does the 210-AHMT support?

A: The S4048T-ON supports the open source Open Network Install Environment (ONIE), enabling installation of Dell EMC Networking OS9 or Dell SmartFabric OS10.

Q: Does the 210-AHMT include transceivers?

A: No. Based on distributor listings, transceivers are not included with this switch; QSFP+ or breakout cables must be purchased separately.

Q: What airflow direction does the 210-AHMT use?
