Maximum dimensions (the depth is the distance from ports on the front panel to the handle on the rear panel): 43.6 mm x 442.0 mm x 448.0 mm (1.72 in. x 17.4 in. x 17.7 in.) Weight (with packaging) 8.6 kg (18.96 lb) Stack ports 10GE SFP+ ports on the front panel RTC Supported RPS Not supported PoE Supported Rated voltage range AC input: 100 V AC to 130 V AC, 200 V AC to 240 V AC, 50/60 Hz High-Voltage DC input: 240 V DC DC input: -48 V DC to -60 V DC Maximum voltage range AC input: 90 V AC to 290 V AC, 45 Hz to 65 Hz High-Voltage DC input: 190 V DC to 290 V DC DC input: -38.4 V DC to -72 V DC Maximum power consumption (100% throughput, full speed of fans) Not providing the PoE function: 121 W 100% PoE loads: 977 W (PoE: 720 W) Typical power consumption (30% of traffic load, tested according to ATIS standard) 95 W Operating temperature -5C to +45C (23F to 113F) at an altitude of 0-1800 m (0-5906 ft.) NOTE: When the altitude is 1800-5000 m (5906-16404 ft.), the highest operating temperature reduces by 1C (1.8F) every time the altitude increases by 220 m (722 ft.). The switch cannot be started when the ambient temperature is lower than 0C (32F). Storage temperature -40C to +70C (-40F to +158F) Noise under normal temperature (27C, sound power) lt, 62.3 dB(A) Relative humidity 5% to 95%, noncondensing Operating altitude 0-5000 m (0-16404 ft.)
