The maximum distance of optical modules used in these conditions cannot exceed 10 km.Storage temperature [°C(°F)]-40°C to +70°C (-40°F to +158°F)Long-term operating relative humidity [RH]5% to 95%, noncondensingLong-term operating altitude [m(ft.)]0-5000 m (0-16404 ft.)Storage altitude [m(ft.)]0-5000 m (0-16404 ft.)Power supply modeAC built-inRated input voltage [V]·         AC input: 100 V AC to 240 V AC, 50/60 HzHigh-Voltage DC input: 240 V DCInput voltage range [V]·         AC input: 90 V AC to 290 V AC, 45 Hz to 65 HzHigh-Voltage DC input: 190 V DC to 290 V DCMaximum input current [A]6 AMemory512 MBFlash memory512 MBConsole portRJ45Eth Management portNot supportedUSBNot supportedRTCNot supportedRPS inputNot supportedService port surge protection [kV]Common mode: ±7 kVPower supply surge protection [kV]±6 kV in differential mode, ±6 kV in common modeTypes of fansBuilt-inHeat dissipation modeHeat dissipation with fan, intelligent fan speed adjustmentAirflow directionAir intake from left and front, air exhaustion from rightPoESupportedCertificationEMC certificationSafety certificationManufacturing certification
