What PoE capabilities does the HPE J9574A provide?

The J9574A supports 48x IEEE 802.3at PoE+ RJ-45 ports with 1080W total budget using dual X312 1000W PSUs. At 120V single PSU delivers 514W PoE; at 240V up to full 1080W. Ideal for powering Aruba APs, cameras, and VoIP phones in dense deployments without external injectors.

What is the switching performance of J9574A?

It offers 176 Gbps full-duplex switching capacity and 130.9 million pps throughput for 64-byte packets. Latency measures <2.8μs at 1Gb and <1.9μs at 10Gb LIFO. Supports 65,500 MAC addresses, 10,000 IPv4/v6 routes, and 36MB dynamic buffers for non-blocking Layer 3 operation.

How does J9574A support network stacking?

Features one open stacking module slot for virtual stacking up to 10 Aruba 3800 switches over standard Ethernet ports. Provides single IP management, hitless failover, and simplified licensing. Enhances resiliency and scalability in campus access layers without dedicated stacking cables.

What are the physical and environmental specs?

1U rack form factor measures 18.4 x 17.43 x 1.7 inches, weighs 16.84 lbs. Operates 0-55°C (45°C max with transceivers), 15-95% humidity non-condensing. Acoustic at 57dB power/41.2dB pressure. Dual hot-swappable PSUs, one fan tray with 4 fans for redundancy.

What uplink options are available on J9574A?

Includes 4 fixed dual-rate 1000/10000 SFP+ ports supporting up to 4 SFP+ transceivers for 10GbE fiber/copper uplinks to aggregation switches. Also provides RJ-45 OOB management and serial console ports. Enables flexible 1G/10G connectivity without additional modules.

Is J9574A suitable for data center use?

Yes, with 176Gbps capacity, low 1.9μs 10Gb latency, and SFP+ uplinks it serves Top-of-Rack in small data centers. 1080W PoE supports inline power for servers or storage; stacking scales multi-rack fabrics. ProVision ASIC handles east-west traffic efficiently.

Product overview

The HPE Aruba 3800 J9574A is a fully managed Gigabit Ethernet Layer 3 switch designed for enterprise campus and branch deployments requiring high-density PoE+ powering. It features 48 autosensing 10/100/1000 RJ-45 PoE+ ports compliant with IEEE 802.3at delivering up to 1080W total PoE budget across two power supply slots, enabling support for power-hungry devices like IP cameras, VoIP phones, and wireless access points. Four fixed dual-speed 1/10GbE SFP+ uplink ports provide high-speed connectivity to aggregation or core layers with min=0 max=4 SFP+ transceivers supported. With 176 Gbps switching capacity and 130.9 million pps throughput (64-byte packets), it handles demanding traffic loads non-blockingly. Latency remains under 2.8μs at 1Gb and 1.9μs at 10Gb for LIFO 64-byte packets. An open stacking module slot enables virtual stacking up to 10 units for simplified management. Embedded HPE ProVision ASIC and dual processors (Freescale PowerPC @1200MHz, ARM @350MHz) with 2GB SDRAM and 4GB flash support advanced features like IPv4/v6 routing (10,000 entries), 65,500 MAC addresses, and 36MB dynamic packet buffer. 1U rack-mountable at 18.4x17.43x1.7 inches weighing 16.84 lbs, it operates 0-55°C with 57dB acoustic noise. Dual X312 1000W PSUs ensure redundancy; max heat 635 BTU/hr. Ideal for scalable access switching powering digital workplace transformations.
