Product Review

The HP J9582A switch offers a significant PoE budget of 1080W and a high switching capacity of 176 Gbps, catering well to high-demand environments requiring substantial power and data throughput. However, its reliance on 1 Gigabit Ethernet PoE+ RJ-45 ports for network connectivity may limit bandwidth for applications necessitating higher speeds, despite the inclusion of four 10 Gigabit Ethernet SFP+ uplink ports for broader network integration. Additionally, its single power supply unit, while efficient, poses a potential single point of failure, which could be a concern for mission-critical applications requiring uninterrupted power.


The HP J9582A, also known by its alternative model number 3800-48G-PoE+-4SFP+, is a high-performance switch designed to accommodate the expanding needs of modern networks. This switch comes equipped with 48 1 Gigabit Ethernet PoE+ RJ-45 network ports, providing ample connectivity for devices requiring both data and power over a single Ethernet cable. The inclusion of 4 10 Gigabit Ethernet SFP+ uplink ports ensures high-speed connectivity to the network backbone or other switches, enabling high-bandwidth applications without bottlenecks. For management and configuration, the HP J9582A offers a console RJ-45 management port and an additional Gigabit Ethernet port for remote management capabilities. A stacking module slot is also available, allowing for the scalable expansion of network capacity and simplified management of multiple switches as a single entity. The switch is powered by a J9580A HPE X312 1000-W power supply, included with the purchase, and supports a total Power over Ethernet (PoE) budget of 1080W. This generous PoE budget enables the switch to power numerous PoE-enabled devices such as wireless access points, VoIP phones, and IP cameras simultaneously. Key hardware specifications of the HP J9582A include a switching capacity of 176 Gbps and a forwarding rate of 130.9 million packets per second (Mpps), indicating its capability to handle large amounts of traffic efficiently. The MAC address table supports up to 65500 entries, facilitating the management of a vast number of connected devices. Latency is exceptionally low, at under 2.8 microseconds for 64-byte packets at 1000 Mbps, ensuring that data packets are forwarded with minimal delay. The switch also features 4 GB of flash memory and 2 GB of SDRAM, providing ample storage and processing power for network operations and configurations. Additionally, the packet buffer size is 36MB, allocated dynamically, to efficiently manage data flow and reduce congestion. HTML bullet points highlighting key features:
  • 48x 1G PoE+ RJ-45 and 4x 10G SFP+ ports for high-density connectivity and uplink capacity.
  • 1080W PoE budget to support multiple PoE devices across the network.
  • Switching capacity of 176 Gbps and forwarding rate of 130.9 Mpps for high-performance data processing and transmission.
The switch's physical characteristics include a 1-RU rack mount form factor, ensuring it can be easily integrated into standard racks. The maximum heat dissipation is 635 BTU/hr, and it operates efficiently across a wide range of voltages (100-120/200-240 V ac) and frequencies (50/60 Hz). The operating temperature range extends from 0° to 55°C, with an operating relative humidity tolerance of 15% to 95% at 40°C, non-condensing, making it suitable for deployment in various environments. In summary, the HP J9582A combines high-density connectivity, substantial PoE power, and advanced management features in a compact, efficient package. Its robust performance specifications and scalability options make it an ideal choice for networks requiring reliability and high performance.
