Slot

  • Power supply slot

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) have two power supply slots, in which power modules can be installed to provide power to the chassis. A chassis can have one or two power modules. Double power modules can provide higher reliability.

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) support double power modules (1+1 backup).
    • When both power modules are working properly, they equally provide power for a chassis.
    • When one power module fails, the other one provides all power required for a chassis.
    All power modules are hot swappable.

  • Fan slot

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI, CE6863-48S6CQ, CE6881-48S6CQ, CE6820-48S6CQ, CE6863-48S6CQ-K, CE6881-48S6CQ-K, CE6881E-48S6CQ and CE6857-48S6CQ-EI) have two fan slots, in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability. A chassis must have two working fan modules to ensure normal operating.

    All fan modules are hot swappable.

    All fan modules are hot swappable.

Airflow

The cooling systems of the CloudEngine 8800, 7800, 6800, and 5800 series switches have front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used. The airflow direction of the power modules and fan modules required on the CloudEngine 8800, 7800, 6800, and 5800 series switches depends on how the switches are installed in cabinets. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If CloudEngine 8800, 7800, 6800, and 5800 series switches are installed with the power supply side facing the front, you are advised to use fan modules and power modules with front-to-back airflow in the switches.
  • Front-to-back airflow: The power modules and fan modules using front-to-back airflow are marked or . Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2-53 (CE5800 as an example).
  • Back-to-front airflow: The power modules and fan modules using back-to-front airflow are marked or . Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 2-54 (CE5800 as an example).

  • When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used.

  • Front-to-back airflow: The power modules and fan modules using front-to-back airflow are marked or . Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2-55 (CE5800 as an example).
  • Back-to-front airflow: The power modules and fan modules using back-to-front airflow are marked or . Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 2-56 (CE5800 as an example).

  • When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used.

Indicators

The downlink service port indicators of the CE6850-48S4Q-EI are 10GE optical port indicators, and other indicators on these models are the same as those on the CE6850-48T4Q-EI. The CE6850-48T4Q-EI is used as an example here to describe the indicators.
