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 2-104 (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 2-105 (using a CE6863 chassis as an example).

Figure 2-104 Front-to-back airflow for port-side exhaust

Figure 2-105 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.

Ports

10GE/25GE SFP28 Optical Port

10GE/25GE SFP28 optical ports cannot work at the rate of 100 Mbit/s. Table 2-226 shows the attributes of a 10GE/25GE SFP28 optical port.

Table 2-226 Attributes of a 10GE/25GE SFP28 optical port

Attribute	Description
Connector type	Depending on the optical module
Optical attributes	Depending on the module or cable in use
Port use constraints	The 48 10GE/25GE SFP28 optical ports of a CE6863 switch work at the rate of 25 Gbit/s by default and do not support GE/10GE auto-sensing. You can set the port rate to 10 Gbit/s or 1 Gbit/s using the port mode 10g or port mode ge command, respectively. The 48 10GE/25GE SFP28 optical ports are divided into 12 port groups, with four ports in each group (1-4, 5-8, 9-12...45-48). If the rate of any port in a port group is set to 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s, all the other ports in this group also work at the rate of 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s. When the ports in a port group work at the rate of 25 Gbit/s, they support only 25GE modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at the rate of 10 Gbit/s, they support only 10GE modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at the rate of 1 Gbit/s, they support only GE modules or cables and will go Down if other types of modules or cables are used.
