Product Review

The HP J9984A switch offers a versatile mix of 24 RJ-45 autosensing 10/100/1000 PoE+ ports and 4 SFP 100/1000 Mb/s ports, catering to a variety of networking needs with support for both fiber and copper connections. However, its operational temperature range is limited to 0°C to 40°C, which may restrict deployment in environments with extreme temperatures. Additionally, with a power over Ethernet (PoE) budget of 370W, it supports numerous PoE devices, though the maximum power rating of 481W suggests careful planning is needed for high-power deployments to avoid overloading.


The HP J9984A is a network switch designed to meet the connectivity needs of modern enterprise networks, offering a blend of performance, scalability, and energy efficiency. This product features a total of 48 RJ-45 autosensing ports, with 24 supporting 10/100/1000 PoE+ (Power over Ethernet Plus) capabilities, and the remaining 24 offering 10/100/1000 connectivity. These ports are designed to automatically adjust for the optimal speed and duplex, with the 10BASE-T/100BASE-TX ports supporting both half and full duplex, while the 1000BASE-T ports operate in full duplex mode only. Additionally, the device includes 4 SFP (Small Form-factor Pluggable) ports that support both 100 Mb/s and 1000 Mb/s speeds, accommodating a range of fiber optic and Ethernet cabling configurations for enhanced network flexibility. These SFP ports conform to IEEE 802.3z Type 1000BASE-X and IEEE 802.3u Type 100BASE-FX standards, ensuring compatibility with a wide array of network infrastructures. Key hardware specifications of the HP J9984A include:
  • PoE Power: 370W, enabling the switch to power connected devices such as IP phones and wireless access points directly over the Ethernet cables, reducing the need for additional power supplies and cables.
  • Dimensions: With a width of 44.25 cm, depth of 32.26 cm, and a height of 4.39 cm, the switch fits comfortably in a standard 1U rack space, making it suitable for compact server rooms.
  • Weight: At 4.4 kg, it is lightweight for its class, facilitating easy installation and maintenance.
Operating conditions for the HP J9984A are designed to be robust enough for most enterprise environments, with an operating temperature range from 0°C to 40°C and a relative humidity range from 15% to 95% (non-condensing). The device can also withstand non-operating/storage temperatures from -40°C to 70°C, and nonoperating/storage relative humidity from 15% to 95% at up to 60°C. It is capable of operating at altitudes up to 3 km, ensuring reliable performance in a variety of geographical locations. The switch's acoustic power level is 45 dB, minimizing noise in office environments. It supports a frequency range of 50/60 Hz and can operate on voltage ranges of 100 - 127 V ac or 200 - 240 V ac, with a current of 5.1/2.6 A depending on the power supply chosen. Its maximum power rating is 481 W, with an idle power consumption of 54.8 W, indicating efficient power usage for its capabilities, particularly with 370 W dedicated to PoE+.
