HPE J9836AS

Aruba (2920‑48G‑PoE+ 740 W) Fully Managed Layer 3 Switch– 48 Ports PoE+

The HPE Aruba J9836A is part of the Aruba 2920 Switch Series offering 44 auto‑sensing 1 GbE PoE+ ports and 4 dual‑personality combo Gigabit ports for copper or SFP mini-GBIC. With an internal 740 W PoE+ budget, it supports high-density deployments of Wi‑Fi APs, IP phones, security cameras, and IoT devices without auxiliary injectors. Fully managed with Layer 3 capabilities—static IP routing, RIP‑1/2, multicast MLD—it is ideal for SMB, campus access, and branch office networks seeking enterprise-grade performance and simplicity. Stackable via optional module (up to 4 units) for single-IP management, this model combines reliability, scalability, and flexibility in a standard 1U rack format.

Features

Building on the Aruba 2920 architecture, the J9836A delivers 176 Gb/s switching capacity and supports packet throughput up to 130.9 Mpps, with low-layer 3 latency (≤ 3.2 µs for 1 Gb/s and 10 Gb/s packets) . Powered by a tri-core ARM1176 processor at 625 MHz with 512 MB SDRAM and 1 GB flash, plus 11.25 MB packet buffer, it provides stable performance under sustained throughput and PoE loads Management includes CLI, web GUI, Aruba Central integration, AirWave, SNMPv1/v2c/v3, RMON, Telnet, FTP, and REST API support. Dual personality port design allows flexibility in uplink choice: copper or fiber SFP with PoE function support . Supports IPv4 routing table up to 2,048 entries and IPv6 up to 256 entries as well as MAC table size of ~16,000 entries

Advanced Options

The switch provides enterprise-grade features such as 802.3at PoE+, Auto-MDIX, energy-efficient Ethernet, LACP trunking, LLDP, STP variants, UDLD, ACLs, QoS with CoS support, VLAN segmentation, and jumbo frames up to 9,220 bytes Optional stacking (up to 4 units) simplifies network growth while maintaining unified management. Designed for dependable, high-capacity edge networking, this switch ensures precise forwarding performance thanks to its robust hardware architecture and large buffer memory. The PoE+ budget of 740 W supports high-port-power devices such as high-end APs or PTZ cameras without requiring external injectors . With idle consumption at just ~52 W and maximum power draw under heavy load at 487 W, efficiency is optimized even under full utilization Operating silently (~53 dB acoustic power) and within an operating temperature range of 0–55 °C, the switch is well-suited to enterprise rack and closet environments. Stack resilience ensures redundancy, combined with enterprise-class features like ACL-based segmentation, energy-efficient EEE, and robust QoS prioritization for critical data and voice traffic
