What is the PoE capability and power budget of the Dell S3124P?

The S3124P provides 24x 1GbE RJ45 ports with IEEE 802.3at PoE+ support up to 30.8W per port. The included 715W hot-plug AC PSU delivers sufficient budget for full PoE+ on all ports simultaneously, powering devices like wireless APs, IP cameras, and VoIP phones without external supplies.

What Layer 3 routing features does the S3124P support?

As a full Layer 3 switch, it supports OSPFv2, VRRP, IGMPv3, MSDP, static routing, and VRF-lite with 16K IPv4/8K IPv6 dynamic routes. 4K VLANs, 128 link aggregation groups, and line-rate L3 forwarding at 158Mpps enable efficient subnet segmentation and redundancy in enterprise networks.

How does the S3124P perform in high-density deployments?

212Gbps switching fabric and 158Mpps forwarding deliver non-blocking performance for 24 Gigabit ports plus 10GbE uplinks. 4MB buffer, 32K MAC table, and jumbo frames up to 9KB handle bursts effectively, ideal for ToR in data centers or access layers with heavy east-west traffic.

What stacking and management options are available?

Integrated stacking ports support up to 84Gbps bandwidth across multiple units for simplified management as a single logical switch. Management via SNMPv1-3, RMON 1-3/9, RADIUS authentication, CLI, and USB console enables centralized control in stacked enterprise deployments.

What are the physical dimensions and airflow design?

1RU rack-mountable at 1.73 x 17.09 x 10.07 inches (44 x 434 x 256 mm) with front-to-back (IO-to-PSU) airflow for efficient cooling in standard 19-inch racks. Optional 1+1 redundant PSU enhances reliability in mission-critical environments.

Is the S3124P suitable for data center top-of-rack use?

Yes, with low-latency line-rate L2/L3 switching, 2x 10GbE SFP+ uplinks, and Active Fabric compatibility for two-tier 1/10GbE architectures. Optimized for high-density GbE ToR connecting servers to S/Z-Series core switches in cloud and enterprise data centers.

Product overview

The Dell PowerSwitch S3124P is a high-performance Layer 3 stackable switch optimized for enterprise access and aggregation layers. It features 24x auto-sensing 10/100/1000Mb RJ45 PoE+ ports delivering up to 30.8W per port with a 715W internal hot-plug PSU, enabling direct powering of IP cameras, VoIP phones, and wireless APs. Dual 10GbE SFP+ fixed uplinks and 2x GbE RJ45/SFP combo ports provide high-speed connectivity to core networks. With 212Gbps full-duplex switching fabric and 158Mpps forwarding rate, it ensures non-blocking wire-speed performance across all ports. Key benefits include 4MB packet buffer for burst handling, 32K MAC addresses, 4K VLANs, OSPFv2 routing, VRRP redundancy, and front-to-back airflow for dense rack deployments. Stacking support scales up to multiple units with 84Gbps inter-switch links. Ideal for mid-sized enterprises, campus networks, and edge data centers requiring reliable PoE distribution and L3 intelligence.
