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).
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.
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.
or 
. Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2-94 (CE5800 as an example).
or 
. Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 2-95 (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.

10GE/25GE SFP28 Optical Port
10GE/25GE SFP28 optical ports cannot work at the rate of 100 Mbit/s. Table 2-210 shows the attributes of a 10GE/25GE SFP28 optical port.
Table 2-210 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 CE6860 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. If GE mediums are installed on the first eight 25GE interfaces, you need to run the port mode ge command to configure the interfaces to work at the rate of 1 Gbit/s; if GE mediums are installed on the later 40 25GE interfaces, the port mode 10g command needs to be run, the interfaces automatically work at the rate of 1 Gbit/s, and the port mode ge command does not need to be run. 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 or 25GE variable-rate 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. If the switch is running a version earlier than V200R002C50, the ports in a port group must use the same type of transmission medium (copper or fiber). This constraint does not apply to V200R002C50 and later versions. |
