What is the maximum switching capacity and latency of the HPE 3800-24G-2SFP+?

The switch delivers 88 Gbps non-blocking switching capacity with latency under 2.8 microseconds for 64-byte packets at 1000 Mb/s and 10 Gb/s. This ensures wire-speed forwarding across all 24 Gigabit ports and 2 SFP+ uplinks simultaneously without congestion or performance degradation.

How many switches can be stacked together, and what is the stacking throughput?

Up to 5 switches can be configured in a fully meshed stack topology, delivering 336 Gb/s total stacking throughput with 42 Gb/s per stacking port in each direction. Ring and chain topologies support up to 10-member configurations, providing flexible deployment options for campus networks.

Does this switch support Power over Ethernet (PoE)?

The J9575A model does not include PoE+ on its 24 Gigabit ports. However, HPE offers the J9573A variant with 24 PoE+ ports (30W per port) if power delivery to connected devices is required. Check model specifications before purchasing.

What management and SDN capabilities are included?

The switch includes out-of-band management via dedicated RJ-45 port, serial console access, and OpenFlow support for Software-Defined Networking. OpenFlow enables separation of control and data planes, allowing centralized management and programmable switching for dynamic network provisioning.

What are the power supply specifications and redundancy options?

The switch includes 2 hot-swappable power supply slots (1 minimum required). Each supply is rated at 400W (100-240 VAC input, 50/60 Hz). Dual supplies enable complete power redundancy, and the secondary supply can increase total available PoE+ power in PoE+ models.

What is the routing capacity and MAC address table size?

The switch supports 10,000 IPv4 routing table entries and 65,500 MAC address table entries. This capacity supports complex enterprise routing policies and large-scale network topologies with thousands of connected devices and VLANs.

What are the physical dimensions and rack mounting requirements?

The switch measures 46.74 x 44.27 x 4.32 cm (18.4 x 17.43 x 1.7 inches) and weighs 15.26 lb (6.92 kg) with one power supply installed. It is a 1U rack-mountable device compatible with standard 19-inch EIA telco racks and equipment cabinets.

Product overview

The HPE 3800-24G-2SFP+ (J9575A) is a fully managed Layer 3 stackable Gigabit Ethernet switch designed for enterprise network deployments. It features 24 autosensing 10/100/1000 RJ-45 ports and 2 fixed 1000/10000 SFP+ uplink ports, delivering 88 Gbps switching capacity with sub-3µs latency. The switch utilizes HPE ProVision ASIC technology with dual processors (350 MHz ARM and 1200 MHz Freescale P2020), 4GB flash, and 2GB SDRAM with 18MB packet buffer. It supports meshed stacking topology (up to 5-member fully meshed stacks), OpenFlow SDN capabilities, and distributed trunking for loop-free redundancy. The 1U rack-mountable design includes dual hot-swappable power supply slots, out-of-band management port, and serial console. Operating temperature range is 0-55°C with maximum 45°C when transceivers are installed. Ideal for mid-to-large enterprise networks requiring high-performance switching, advanced routing, and network resilience.
