Maximum dimensions (the depth is the distance from ports on the front panel to the parts protruding from the rear panel): 43.6 mm x 442.0 mm x 227.0 mm (1.72 in. x 17.40 in. x 8.94 in.) Dimensions with packaging (H x W x D) [mm(in.)] 90 mm x 550 mm x 355 mm (3.54 in. x 21.65 in. x 13.98 in.) Chassis height [U] 1 U Weight without packaging [kg(lb)] 3.13 kg (6.90 lb) Weight with packaging [kg(lb)] 4.49 kg (9.90 lb) Typical power consumption [W] 66.85 W Typical heat dissipation [BTU/hour] 228.10 BTU/hour Maximum power consumption [W] 93.92 W Maximum heat dissipation [BTU/hour] 320.46 BTU/hour MTBF [year] 32.56 year MTTR [hour] 2 hour Availability gt,0.99999 Noise at normal temperature (acoustic power) [dB(A)] 41.42 dB(A) Noise at normal temperature (acoustic pressure) [dB(A)] 27.74 dB(A) Number of card slots 0 Number of power slots 0 Number of fans modules 2 Redundant power supply Not supported Long-term operating temperature [C(F)] -5C to +45C (23F to 113F) at an altitude of 0-1800 m (0-5906 ft.) Short-term operating temperature [C(F)] -5C to +50C (23F to 122F) at an altitude of 0-1800 m (0-5906 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 1C (1.8F) every time the altitude increases by 220 m (722 ft.). The device can work for a short period of time when the operating temperature is beyond the normal range, but the following conditions must be met: The operating temperature can exceed 45C (113F) for a maximum of 96 consecutive hours in a year. The total time when the operating temperature exceeds 45C (113F) in a year is less than or equal to 360 hours. The number of times the operating temperature exceeds 45C (113F) is less than or equal to 15 in one year. If any of the preceding conditions is not met, the device may be damaged or an unknown error may occur. Devices cannot start when the temperature is lower than 0C (32F). The maximum transmission distance of an optical module used for short-term operation cannot exceed 10 km. Storage temperature [C(F)] -40C to +70C (-40F to +158F) Long-term operating relative humidity [RH] 5% to 95%, noncondensing Long-term operating altitude [m(ft.)] 0-5000 m (0-16404 ft.)
