This makes the switch an ideal choice for organizations looking to enhance their network infrastructure with scalable and high-capacity networking hardware. In terms of physical dimensions, the switch measures 17.5 inches in width, 36.75 inches in height, and 32 inches in depth, with a weight of 675 lb (306.17 kg) when fully populated. This size and weight make it suitable for installation in standard data center racks, providing a compact yet powerful networking solution. Power efficiency is a crucial aspect of the Juniper QFX3008-SF16Q, with a power feed (voltage) range of 200-240 V AC for single phase and 240 V for three-phase configurations. The AMP rating stands at 16 A per input for single phase and 25.5 A per phase for three-phase power feeds. When fully loaded, the chassis consumes a maximum of 6,420 watts and operates nominally at 4,620 watts. This power efficiency is complemented by its heat dissipation capabilities, with a maximum output of 21,290 BTU and a nominal output of 15,763 BTU for a fully loaded chassis. The switch supports front-to-back air flow, ensuring optimal cooling and performance under heavy loads. For installation, it offers 4-pole rack mount options, providing flexibility in different data center environments. Operating conditions for the Juniper QFX3008-SF16Q are designed to accommodate a wide range of environments. The operating temperature ranges from a minimum of 41°F to a maximum of 104°F, with storage temperatures spanning from -40°F to 158°F. It can operate at altitudes up to 10,000 ft (3,048 m) and be stored at altitudes up to 40,000 ft (12,192 m). Relative humidity levels for operation range from a minimum of 8% to a maximum of 90% (non-condensing), and for non-operating conditions, from a minimum of 5% to a maximum of 95%. Key hardware specifications include:
  • 16-port QSFP front card for high-density connectivity
