Description

CE7855-EI-B-B0A Overview Huawei CloudEngine 7800 series (CE7800 for short) switches are next-generation 40G Ethernet switches designed for data centers and high-end campus networks, providing high-performance, high-density 40GE ports, and low latency. The CE7800 has an advanced hardware architecture with 40GE QSFP+ ports. Using the Huawei VRP8 software platform, CE7800 switches provide extensive data center service features and high stacking capability. In addition, the airflow direction (front-to-back or back-to-front) can be changed. Supported Transceivers Model Description OMXD30000 Huawei Optical Transceiver OMXD30000, SFP+, 10G, Multi-mode Module (850nm, 0.3km, LC) SFP-GE-LX-SM1310 Optical Transceiver, eSFP, GE, Single-mode Module (1310nm, 10km, LC) OMXD30009 Transceiver, QSFP+, 1310nm, 41.25Gbps, -7dBm, 2.3dBm, -11.5dBm, LC, SMF, 10 ESFP-GE-SX-MM850 Optical Transceiver, eSFP, GE, Multi-mode Module (850nm,0.5km, LC) CE7855-EI-B-B0A Specification CE7855-EI-B-B0A Specification Item Description Physical specifications Dimensions (W x D x H): 442.0 mm x 607.0 mm x 43.6 mm (17.4 in. x 23.9 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): 11.2 kg (24.69 lb) Environment parameters Temperature Operating temperature: 0C to 40C (32F to 104F) 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 1C (1.8F) every time the altitude increases by 220 m (722 ft.). Storage temperature: -40C to +70C (-40F to +158F) Relative humidity 5% RH to 95% RH, noncondensing Altitude lt, 5000 m (16404 ft.) Noise (sound pressure, 27C) Back-to-front airflow: lt, 55 dBA Front-to-back airflow: lt, 54 dBA Power specifications Power source type AC AC power input Rated input voltage range: 100 V AC to 240 V AC, 50/60 Hz Maximum 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 DC Maximum voltage range: -38.4 V DC to -72 V DC High-voltage DC power input Not supported Rated input current 600 W AC power (PAC-600WA series): 9 A (100 V AC to 240 V AC) 600 W DC power (PDC600S12 series): 20A (-48 V DC to -60 V DC) Chassis power consumption Maximum power consumption 444 W Typical power consumption 262 W (100% throughput, QSFP+ cables on 32 ports, double power modules) Chassis heat dissipation Maximum heat dissipation 1515 BTU/hr Typical heat dissipation 895 BTU/hr (100% throughput, QSFP+ cables on 32 ports, double power modules) Surge protection AC Power module: 6 kV in common mode and 6 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 and availability Power module backup 1+1 backup Fan module backup 1+1 backup not supported NOTE: CE7800 chassis uses two fan modules, with each fan module containing two fans. The four fans in the chassis work in 3+1 backup mode.
