Six 40GE QSFP+ Ethernet optical ports NOTE:
A 40GE QSFP+ port can be split into four 10GE ports. In V200R005C00 and later versions, a QSA convertor can be installed on a 40GE interface that has been split. Installing a medium whose rate is 10 Gbit/s on the QSA convertor makes a 40GE interface function as a 10GE interface. Only the first split interface works and other three split interfaces are unavailable. If a QSA convertor is installed on an interface that is not split or a medium whose rate is not 10 Gbit/s is installed on the QSA convertor on an interface that has been split, the interface enters the Down(Transceiver type mismatch) status.

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.
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
- 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.
Indicators
The downlink service port indicators of the CE6856-48T6Q-HI are 10GE electrical port indicators, and other indicators on the CE6856-48T6Q-HI are the same as those on the CE6850-48S6Q-HI. This figure shows the indicators on the CE6850-48S6Q-HI.

Each 40GE port has a single-color indicator, which shows the status of the 40GE port by default. If a 40GE port is not split and is connected to four 10GE ports on a remote device using a 1-to-4 cable, the 40GE port cannot go Up and its indicator is off. |

40GE QSFP+ Ethernet Optical Port
Console Port
- 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 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 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.
