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, CE6820-48S6CQ-A, 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.

• 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 3-55 (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 3-56 (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.

Ports

10GBASE-T Ethernet Electrical Port

A 10GBASE-T Ethernet electrical port receives and sends service traffic at the rate of 100 Mbit/s, 1000 Mbit/s, or 10 Gbit/s. The port can work at the rate of 100 Mbit/s or 1000 Mbit/s through auto-sensing. 10GBASE-T Ethernet electrical ports must use Category 6A shielded Ethernet cables or higher Ethernet cables. Table 3-125 shows the attributes of a 10GBASE-T Ethernet electrical port.

Table 3-125 Attributes of a 10GBASE-T Ethernet electrical port

40GE QSFP+ Ethernet Optical Port

A 40GE QSFP+ Ethernet optical port receives and sends services at the rate of 40 Gbit/s. If a 40GE QSFP+ Ethernet optical port is split into four 10GE ports, it must use 1-to-4 QSFP+ optical modules and optical fibers or 1-to-4 QSFP+ cables. Table 3-126 describes the attributes of a 40GE QSFP+ Ethernet optical port.

Table 3-126 Attributes of a 40GE QSFP+ Ethernet optical port

Console Port

The console port is connected to a console for onsite configuration. The port must use a console cable. Table 3-127 describes the attributes of the console port.

Table 3-127 Attributes of the console port

ETH Management Port (RJ45)

The ETH management port (RJ45) of a switch is connected to the network port of a configuration terminal or network management workstation to set up the onsite or remote configuration environment. The ETH management port (RJ45) uses a Category 5 or higher category cable. Table 3-128 describes the attributes of the ETH management port (RJ45).

Table 3-128 Attributes of the ETH management port (RJ45)

USB Port

A USB flash drive can be connected to the USB port for log backup, system software backup and uploading, or USB-based deployment.
