Uplink ports 4 x 10GE SFP ports Downlink ports 24 x 10/100/1000BASE-T ports Redundant power supply Not supported Long-term operating temperature [°C(°F)] -5°C to 50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44 ft.) Restriction on the operating temperature variation rate [°C(°F)] When the altitude is 1800–5000 m (5906–16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). Devices cannot start when the temperature is lower than 0°C (32°F). Storage temperature [°C(°F)] –40°C to 70°C (–40°F to 158°F) Long-term operating relative humidity [RH] 5% RH to 95% RH (non-condensing) Long-term operating altitude [m(ft.)] 0–5000 m (0–16404 ft.)
