A single RJ-45 serial console port is included for management and setup, facilitating easy configuration and maintenance.
The physical dimensions of the HP JG300B, standing at 17.32 inches in width, 10.24 inches in depth, and 1.72 inches in height, make it a compact solution that fits comfortably in a 1U rack space. This size efficiency does not come at the expense of performance, as the device weighs 11.02 lb (5 kg) and is designed for easy installation in an EIA-standard 19-inch telco rack or equipment cabinet, with mounting hardware included.
Operationally, the HP JG300B is designed to function within a broad range of environmental conditions. It operates effectively at temperatures ranging from 32°F (0°C) to 122°F (50°C) and can withstand non-operating temperatures from -40°F (-40°C) to 158°F (70°C). The device's operational humidity range is from 5% to 95% non-condensing, ensuring reliability in various atmospheric conditions. Furthermore, the switch's storage conditions mirror its operational tolerances, maintaining integrity between 5% and 95% non-condensing humidity.
The HP JG300B incorporates a dual-speed fan system to manage its thermal output efficiently, with noise levels of 44.7 dB in low-speed mode and 53.8 dB at high speed, ensuring a relatively quiet operation. It requires a power supply of 100–240 VAC or -48 to -60 VDC, with a maximum power rating of 43 W. The device's maximum heat dissipation stands at 147 BTU/hr (155.08 kJ/hr), indicative of its energy efficiency and the effectiveness of its cooling systems. Operating at a frequency of 50/60 Hz, the HP JG300B is adaptable to various electrical systems, making it suitable for deployment in diverse geographical locations.
