Physical specifications

• Dimensions (W x D x H): 442.0 mm x 600.0 mm x 43.6 mm (17.4 in. x 23.6 in. x 1.72 in.)
• Weight (with two power modules and two fan modules, calculated based on the heaviest model if multiple models are supported): 12.6 kg (27.78 lb)

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: < 53 dBA
• Front-to-back airflow: < 53 dBA

Power source type

AC/DC/high-voltage DC

AC power input

• Rated input voltage range: 100 V AC to 240 V AC, 50/60 Hz

Typical power consumption

219 W (100% throughput, 3 m Ethernet cables on 48 ports and QSFP+ cables on 6 ports, double power modules)

Maximum heat dissipation

1181 BTU/hr

Typical heat dissipation

747 BTU/hr (100% throughput, 3 m Ethernet cables on 48 ports and QSFP+ cables on 6 ports, double power modules)

Surge protection

Ethernet electrical ports: 2 kV in common mode

Power module:

• AC: 4 kV in common mode and 2.5 kV in differential mode
• DC: 4 kV in common mode and 2 kV in differential mode

Heat dissipation mode

Air cooling

Airflow

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