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.
- 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.
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 2-91 (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 2-92 (using a CE6863 chassis as an example).
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 CE6857-48S6CQ-EI switch does not have the ETH management port indicator. The service port indicators are 10GE and 40GE/100GE port indicators, and other indicators are the same as those on the CE6865-48S8CQ-EI. The CE6865-48S8CQ-EI is used as an example here to describe the indicators.
