What is the PoE capacity and port configuration of HPE J9573A?

HPE J9573A provides 24x RJ-45 autosensing 10/100/1000 PoE+ ports compliant with IEEE 802.3at, delivering 720W total PoE power from the included 1000W X312 PSU. This supports full Class 4 PoE+ devices across all ports with single PSU at 120V input up to 572W available.

What performance metrics define the J9573A switching capabilities?

Switching capacity reaches 88 Gb/s full duplex with 65.4 million packets per second throughput for 64-byte packets. Latency measures <2.8 μs at 1GbE and <1.9 μs at 10GbE using LIFO 64-byte packets, powered by HPE ProVision ASIC and 18MB dynamic packet buffer.

How does stacking work on the Aruba 3800 J9573A?

Features 1x open stacking module slot supporting up to 10 switches in a stack for simplified management as single logical unit. Uses dedicated stacking ports via optional modules, enabling resilient ring topology with hitless failover for campus access deployments.

What management options are available on J9573A?

Includes 1x RJ-45 serial console, 1x RJ-45 out-of-band management port, and USB port. Runs Aruba ProVision OS with CLI, Web GUI, and supports centralized management via Aruba Central cloud platform for configuration, monitoring, and analytics.

What are the physical and environmental specs for rack deployment?

1U rack height measures 46.74 x 44.27 x 4.32 cm, weighs 7.21 kg. Operates 0-45°C, up to 3km altitude, acoustic 49 dB power/33.7 dB pressure. Dual PSU slots with redundant 100-240VAC input, max 127W draw, 434 BTU/hr heat dissipation.

Is J9573A suitable for high-density enterprise access?

Yes, with 24 PoE+ ports, 10G uplinks, 10k IPv4 routes, 64k MAC addresses, and robust QoS for voice/video prioritization. Non-blocking architecture and stacking make it ideal for aggregating user access in campus/branch with future-proof scalability.
