Product Review

The HP J9584A offers a versatile array of connectivity options, including 24 SFP 100/1000 Mb/s ports and additional 2 fixed 1000/10000 SFP+ ports, catering well to high-speed networking demands. However, its limitation to full-duplex mode only on 1000BASE-T ports may restrict certain network configurations. The unit's compact design, with 1U height and a weight of 7.26 kg, facilitates easy integration into racks but its power efficiency and heat dissipation, peaking at 127 W and 434 BTU/hr respectively, could be a concern for energy-conscious deployments.


The HP J9584A is a versatile networking switch designed for efficiency and scalability within enterprise networks. This device offers a comprehensive set of features tailored for robust network management and high-speed connectivity. The hardware specifications highlight its capability to support a wide range of networking requirements. At the core of the HP J9584A are 24 SFP 100/1000 Mb/s ports that comply with IEEE 802.3u Type 100BASE-TX and IEEE 802.3ab Type 1000BASE-T standards, supporting both half and full duplex modes at 100BASE-TX and full duplex mode exclusively at 1000BASE-T. Additionally, the switch is equipped with two fixed 1000/10000 SFP+ ports, enhancing its uplink capabilities. For configuration and management, it features one RJ-45 serial console port and one RJ-45 out-of-band management port. The inclusion of one stacking module slot further underscores its ability to scale within network infrastructures.
  • Dimensions are precisely 46.74 cm in width, 44.27 cm in depth, and 4.32 cm in height, conforming to a 1U rack-mountable form factor, making it ideal for space-constrained environments.
  • It weighs 7.26 kg, ensuring it is both substantial and manageable for installation.
  • The switch is powered by one HP X311 400W power supply (J9581A), supporting a voltage range of 100-127/200-240 V ac, and operates efficiently with an idle power consumption of 55W and a maximum power rating of 127W.
This device's thermal management is facilitated by a J9582A fan tray, maintaining optimal operating conditions with a maximum heat dissipation of 434 BTU/hr. Its operational integrity is guaranteed within a temperature range of 0° to 45°C and a relative humidity range of 15% to 95% at 40°C, non-condensing. For storage, it withstands temperatures from -40° to 70°C and a relative humidity of 15% to 90% at 65°C, non-condensing. The HP J9584A operates quietly with an acoustic power level of 36 dB and a pressure level of 25 dB, minimizing noise in work environments. Its performance is highlighted by a 1000Mb latency of less than 2.8 μs for 64-byte packets (LIFO), ensuring swift data transmission that is critical for network efficiency and high-speed connectivity. Designed to meet the demands of modern network infrastructures, the HP J9584A switch addresses the needs for high-performance, reliable networking with its comprehensive port offerings, efficient power management, and operational resilience.
