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.

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 2-86 (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 2-110 (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 2-194 shows the attributes of a 10GBASE-T Ethernet electrical port.

Table 2-194 Attributes of a 10GBASE-T Ethernet electrical port

Attribute	Description
Connector type	RJ45
Standards compliance	IEEE802.3an and IEEE802.3az
Applicable cable	Straight-through cable and crossover cable
Working mode	Supported rate: 100/1000 Mbit/s and 10 Gbit/s auto-sensing Full-duplex
Maximum transmission distance	100 m

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 2-195 describes the attributes of a 40GE QSFP+ Ethernet optical port.

Table 2-195 Attributes of a 40GE QSFP+ Ethernet optical port

Attribute	Description
Connector type	LC/MPO
Optical port attributes	Depending on the module or cable in use
Standards compliance	IEEE802.3ba
Working mode	Full-duplex

Console Port

The console port is connected to a console for onsite configuration. The port must use a console cable. Table 2-196 describes the attributes of the console port.

Table 2-196 Attributes of the console port

Attribute	Description
Connector type	RJ45
Standards compliance	RS232
Working mode	Duplex Universal Asynchronous Receiver/Transmitter (UART)
Baud rate	9600 bit/s to 115200 bit/s Default value: 9600 bit/s

The console port and Mini USB port share one internal serial port. You can use the console port or Mini USB port as the serial port according to your needs. When the Mini USB is activated, the console port cannot be used.
When both the console port and Mini-USB port have a cable connected, the Mini-USB port is used.

Mini USB Port

The Mini USB port can connect to a configuration terminal for onsite configuration of the system, but the configuration terminal must have a USB serial port driver installed. The Mini USB port is used as the serial port once a link is established on the port.

ETH Management Port (Combo)

The ETH management port (combo) consists of an electrical port and an optical port. You can connect the electrical or optical port to a configuration terminal or network management workstation to set up the onsite or remote configuration environment. The electrical and optical ports are logically multiplexed, and only one of them can work at a time.

The combo port automatically selects the working mode as follows:

If the optical port has no optical module installed and the electrical port has no network cable connected, the port type depends on which port is connected first. If the electrical port is connected by a network cable first, the electrical port is used for data switching. If the optical port has an optical module installed first, the optical port is used for data switching.
If the electrical port has a network cable connected and is in Up state, the electrical port is still used for data switching when the optical port has an optical module installed.
If the optical port has an optical module installed and is in Up state, the optical port is still used for data switching when the electrical port has a network cable connected.
If the optical port has an optical module and optical fiber installed and the electrical port has a network cable connected, the optical port is used for data switching after the switch restarts.

The combo electrical port uses a Category 5 or higher category network cable. Table 2-197 describes the attributes of the combo electrical port.

Table 2-197 Attributes of the combo electrical port

Attribute	Description
Connector type	RJ45
Standards compliance	IEEE802.3ab
Working mode	Supported rate: 10/100/1000 Mbit/s auto-sensing Full-duplex
Maximum transmission distance	100 m

The combo optical port uses a 100M or GE optical module and matching optical fibers. A 100M optical module can be used only after the switch starts successfully. If a 10GE optical module is installed, the interface can go Up, but the system displays an alarm message, indicating that the interface does not support the optical module. If a GE copper module is installed and the remote interface also has a GE copper module installed, the local interface can go Up but does not support rate configuration. Table 2-198 describes the attributes of the combo optical port.

Full-duplex

The CE6856-48T6Q-HI switch has two ETH management ports (combo). Pay attention to the following when using the two management ports:

The two ports cannot be used together, and you must choose one of them to use.
Before start of a CE6856-48T6Q-HI switch, you can select interface 1 or interface 2 in the BIOS menu. Interface 1 is the default choice. For details, see "Modify parameters" in the Basic Configuration Guide - BIOS Menu.
After registration of the switch succeeds:
- If both the management ports have a cable connected and are in Up state, port 1 acts as the primary management port and port 2 becomes the backup automatically. The management interface number displayed on the command line interface is MEth0/0/0, regardless of which port is used.
- If cables are connected to the two ETH management ports after successful registration of the switch, the port that is connected first is used as the primary management port.
- If port 1 fails, the system switches management traffic to port 2 automatically. When port 1 recovers, management traffic cannot be switched back to port 1, unless port 2 fails or the switch restarts. You can observe indicators on the ETH management ports to determine which port is used currently. (The Link indicator of the ETH management port used is steady green. If data is being transmitted on this port, its ACT indicator is blinking yellow. The indicators of the backup port are off.)

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.
