Physical specifications

Dimensions (W x D x H): 442.0 mm x 420.0 mm x 43.6 mm (17.4 in. x 16.5 in. x 1.72 in.)

Environment parameters

Temperature

Operating temperature: 0°C to 40°C (32°F to 104°F) at altitude of 0-1800 m (0-5906 ft.)
NOTE:
When the altitude is 1800-5000 m (5096-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.).
Storage temperature: -40°C to +70°C (-40°F to +158°F)

Relative humidity

5% RH to 95% RH, noncondensing

Altitude

< 5000 m (16404 ft.)

Noise (sound pressure, 27°C)

Back-to-front airflow: < 56 dBA
Front-to-back airflow: < 58 dBA

737 BTU/hr

Typical heat dissipation

396 BTU/hr (100% throughput, SFP+ cables on 48 ports and QSFP+ cables on 6 ports, double power modules)

Surge protection

Power module:
AC: 6 kV in common mode and 6 kV in differential mode
DC: 4 kV in common mode and 2 kV in differential mode

Heat dissipation

Heat dissipation mode

Air cooling

Airflow

Front-to-back or back-to-front, depending on the fan modules and power modules
