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 2-55 (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 2-56 (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.

Stack master/slave indicator NOTE:
In V200R003C00 and later versions, you can use the dfs-master led enable command to enable the stack master/slave indicator to display the DFS group master and backup status. After the stack master/slave indicator is enabled to display the DFS group master and backup status, the stack master/slave indicator on the DFS master device is steady on and that on the DFS backup device is off. |

Steady on |
The STACK mode is selected, and service port indicators show the stack member ID or leaf ID of the local switch. NOTE:
In V100R002C00 and later versions, if the indicator mode on any member switch of a stack or SVF system is changed to STACK by pressing the MODE button, all the other member switches in the stack or SVF system change the stack mode to STACK. In this case, service port indicators on the member switches show stack member IDs or leaf IDs of these switches. |
||||
6 |
MODE/ID |
Mode switch button and ID indicator NOTE:
The mode switch button on the rear panel is integrated with the ID indicator. There is only an ID indicator and no mode switch button on the front panel. |
Mode switch button: - |

- |
Service port indicator (10GE electrical port) NOTE:
Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top. |
Meanings of service port indicators vary in different modes. For details, see Table 2-123. |

Service port indicator (40GE optical port) NOTE:
Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top. |
Meanings of service port indicators vary in different modes. For details, see Table 2-123. When a 40GE port is configured as four 10GE ports, this indicator shows the status of a 10GE port. The sequence number of the indicated 10GE port is identified by indicators 40GE Breakout 1/2/3/4 on the lower right corner of the panel. NOTE:
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 one-to-four high-speed cable, the 40GE port cannot go Up and its indicator is off. |

40GE ports are not split into four 10GE ports. |
Steady on |
At least one 40GE port has been split into four 10GE ports. When one or more 40GE ports are configured as four 10GE ports, these indicators identify the sequence numbers of the 10GE ports. A 40GE port indicator (8 in Figure 2-57) shows the status of a 10GE port converted from the 40GE port:
The following is an example: The first 40GE port shown in Figure 2-57 is split into four 10GE ports, and the second 40GE port is not split.
