What is the switching capacity and throughput of HPE J9576A?

The J9576A provides 176 Gbps full-duplex switching capacity and 130.9 million packets per second throughput for 64-byte packets. This non-blocking architecture ensures wire-speed performance across all 48x 1G and 4x 10G ports, ideal for high-bandwidth campus aggregation without bottlenecks.

What ports does the Aruba 3800 J9576A include?

It features 48x RJ-45 autosensing 10/100/1000 ports (full-duplex at 1Gbps), 4x fixed 1000/10000 SFP+ ports, 1x RJ-45 serial console, 1x OOB management port, and 1x stacking module slot. Supports IEEE 802.3 standards for broad compatibility.

Is the J9576A stackable and how?

Yes, via the rear stacking module slot (module sold separately like J9577A), it supports stacking up to 12 units with high-speed interconnects for logical single management entity, reducing complexity in large deployments.

What are the power and environmental specs?

Operates on 100-127/200-240 VAC, 6/3A, idle 70W, max 186W with 635 BTU/hr dissipation. Temperature 0-55°C (45°C max with transceivers), 15-95% humidity non-condensing, altitude up to 3km, acoustic 36dB power level.

What management and processor features does it have?

Powered by HPE ProVision ASIC/ARM @350MHz and Freescale PowerPC @1200MHz with 2GB SDRAM, 4GB flash, 36MB packet buffer. Supports HP PCM+, 65.5K MAC table, 10K routing entries for advanced L2/L3 enterprise features.

How does J9576A compare to similar 3800 models?

Unlike PoE models (J9573A), J9576A is non-PoE with 4x10G SFP+ vs 2x on J9575A, offering higher uplink density. Matches 48G PoE-4XG (J9586A) but uses SFP+ for fiber flexibility in aggregation roles.
