Description

CE6851-48S6Q-HI Switch (48-Port 10G SFP+, 6-Port 40GE QSFP+, Without FAN Box and Power Module)

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)

8.7 kg (19.18 lb)

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

Power source type

AC/DC

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

350 W DC power (PDC-350WA series): 11 A (-48 V DC to -60 V DC)

600 W AC power (PAC-600WA series): 9 A (100 V AC to 240 V AC)

Maximum power consumption

245 W

Typical power consumption

145 W (100% throughput, SFP+ cables on 48 ports and QSFP+ cables on 6 ports, double power modules)

Maximum heat dissipation

836 BTU/hr

Typical heat dissipation

495 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 mode

Air cooling

Airflow

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

Power module backup

1+1 backup

Fan module backup

1+1 backup not supported

NOTE:

A CE6800 chassis uses two fan modules, with each fan module containing two fans. The four fans in the chassis work in 3+1 backup mode.

Hot swap

Supported by all power modules and fan modules
