Forty-eight 10GE SFP+ Ethernet optical ports

Applicable modules and cables:

NOTE:

GE media cannot be installed on 10GE ports numbered from 13 to 16 and from 25 to 28 on the CE6881 in V200R005C20. If GE medium is installed on such ports, the ports will be set to the Error-Down state. In V200R019C10 and later versions, after GE medium is installed on 10GE ports numbered from 13 to 16 and from 25 to 28, you need to run the speed 1000 command to change the port rate to 1000 Mbit/s so that the ports can go Up. The rate of such ports numbered from 13 to 16 or from 25 to 28 will be changed simultaneously. For example, if you run the speed 1000 command on port 13 that has a GE medium installed, the rate of ports 14, 15, and 16 will be changed simultaneously.

Six 40GE/100GE QSFP28 Ethernet optical ports

Applicable modules and cables:
  • QSFP+ to QSFP+ AOC cable
  • QSFP+ to QSFP+ high-speed cable (The cable can only be used as a stack cable or be used to connect peer-link interfaces in an M-LAG.)
  • QSFP28 to QSFP28 AOC cable
  • QSFP28 to QSFP28 high-speed cable (The cable can only be used as a stack cable or be used to connect peer-link interfaces in an M-LAG.)
    NOTE:

    When a QSFP28 high-speed cable is installed on a 100GE port that works at the rate of 100 Gbit/s, the port supports only the 1 m QSFP28 high-speed cable.

    When a QSFP28 high-speed cable is installed on a 100GE port and the speed 40000 command is run to set the rate to 40 Gbit/s, the port supports 1 m, 3 m, and 5 m QSFP28 high-speed cables.

Slot Description

Power Slots

Each of the CloudEngine 6800 series switches has two power module slots and supports pluggable power modules. A chassis can use one or two power modules. In particular, dual power modules provide higher reliability.

The CloudEngine 6800 series switches support 1+1 backup of power modules.
  • When both power modules are working properly, each of them provides half of the power required for the chassis.
  • When one power module fails, the other one provides all power required for the chassis.
All power modules of the devices are hot swappable.

Fan Slots

Each of the CloudEngine 6800 series switches has four fan slots in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability.

It is recommended that four fan modules be properly installed on a switch to ensure normal switch operating. The device supports four pluggable 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.

All fan modules are hot swappable.

Heat Dissipation System

The cooling system of the CloudEngine 6800 series switches uses front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used.

  • Front-to-back airflow: Power modules and fan modules with front-to-back airflow are identified by . Air flows into the chassis from the power supply side and is exhausted from the port side, as shown in Figure 2-139 (using a CE6863 chassis as an example).
  • Back-to-front airflow: Power modules and fan modules with back-to-front airflow are identified by . Air flows into the chassis from the port side and is exhausted from the power supply side, as shown in Figure 2-140 (using a CE6863 chassis as an example).
Figure 2-139 Front-to-back airflow for port-side exhaust
Figure 2-140 Back-to-front airflow for port-side intake
The airflow direction of the power modules and fan modules required on the CloudEngine 6800 series switches depends on how the device is installed in a cabinet. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If a switch is installed with the power supply side facing the front and the port side facing the back, the switch needs to adopt fan modules and power modules with front-to-back airflow.

Power modules and fan modules using forced air cooling on a switch must have the same airflow direction. If a switch adopts power modules with back-to-front airflow, the switch must use fan modules with back-to-front airflow as well.

Indicators

The downlink service port indicator on the CE6881-48S6CQ is the 10GE optical port indicator. The status and status meanings of other indicators are the same as those of the CE6863-48S6CQ. The CE6863-48S6CQ is used as an example here to describe the indicators.
