The device measures 43.99 cm (17.32 in) in width, 46 cm (18.11 in) in depth, and 4.37 cm (1.72 in) in height, with a weight of 12.5 kg (27.56 lb). - What is the maximum power rating and idle power consumption?
The maximum power rating is 150 W, and the idle power consumption is 70 W. - How much PoE power does the device provide?
The device provides 740 W of PoE+ power. - What are the operating and non-operating temperature ranges?
The operating temperature range is from -40°C to 70°C (-40°F to 158°F), and the non-operating/storage temperature range is the same. - What is the device's maximum heat dissipation?
The maximum heat dissipation is 238 BTU/hr (686.81 kJ/hr), with a range from 201 BTU/hr to 443 BTU/hr, depending on the power supply configuration. - What are the acoustic noise levels for low and high-speed fan modes?
In low-speed fan mode, the acoustic noise level is 57.6 dB, and in high-speed fan mode, it is 66.9 dB ISO 7779.
Product Review
The HP JH147A offers versatile connectivity options, including 24 RJ-45 autosensing 10/100/1000 ports and 4 SFP+ 10GbE ports, along with the flexibility to expand up to 6 SFP+ ports or options for 1/10GBASE-T or 40GbE ports, catering to a variety of network demands. Despite its comprehensive features, the device's noise level ranges from 57.6 dB in low-speed mode to 66.9 dB in high-speed mode, potentially posing a challenge in noise-sensitive environments. Additionally, its power consumption, with an idle power of 70 W and a maximum of 150 W, alongside a PoE+ power of 740 W, requires consideration for energy efficiency and operational cost in planning network infrastructures.
