Part Number | 02352CHR |
Model | CE6857-EI-B-B0B |
Description | CE6857-48S6CQ-EI switch (48*10GE SFP+, 6*100GE QSFP28, 2*AC power modules, 4*fan modules, port-side intake) |
Item | Description | |
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.)Weight (with two power modules and two fan modules, calculated based on the heaviest model if multiple models are supported): 7.6 Kg (16.76 lb) | |
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: < 53 dBAFront-to-back airflow: < 52 dBA | |
Power specifications | Power source type | AC |
AC power input | Rated input voltage range: 100 V AC to 240 V AC, 50/60 HzMaximum input voltage range: 90 V AC to 290 V AC, 47 Hz to 63 Hz | |
DC power input | Rated voltage range: -48 V DC to -60 V DCMaximum voltage range: -38.4 V DC to -72 V DC | |
High-voltage DC power input | Not supported | |
Rated input current | 350 W DC power (PDC350S12 series): 11 A (-48 V DC to -60 V DC) 600 W AC power (PAC600S12 series): 9 A (100 V AC to 240 V AC) | |
Chassis power consumption | Maximum power consumption | 287 W |
Typical power consumption | 152 W (100% throughput, SFP28 cables on 48 ports and QSFP28 cables on 6 ports, double power modules) 195 W (100% throughput, all optical interfaces on the switch are equipped with the short-distance optical modules, double power modules) | |
Chassis heat dissipation | Maximum heat dissipation | 979 BTU/Hr |
Typical heat dissipation | 519 BTU/Hr (100% throughput, SFP28 cables on 48 ports and QSFP28 cables on 6 ports, double power modules) 665 BTU/Hr (100% throughput, all optical interfaces on the switch are equipped with the short-distance optical modules, double power modules) | |
Surge protection | Power module:AC: 6 kV in common mode and 6 kV in differential modeDC: 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 | |
Reliability | Power module backup | 1+1 backup |
Fan module backup | The device supports 3+1 backup of fan modules that work in hot standby mode. The system can operate properly for a short time after a single fan module fails. You are advised to replace the faulty fan module immediately. | |
Hot swap | Supported by all power modules and fan modules | |
