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 2-169 (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

Indicators on the CE8850-32CQ-EI are the same as those on the CE7850-32Q-EI. CE7850-32Q-EI is used as an example.

Figure 2-171 Indicators on the CE8850-32Q-EI rear panel

Figure 2-172 Indicators on the CE8850-32Q-EI front panel

Table 2-350 Indicator description

No.	Indicator	Name	Color	Status	Description
1	SYS	System status indicator	Green	Off	The system is not running.
				Fast blinking	The system is starting.
				Slow blinking	The system is running normally.
			Red	Steady on	The system fails to start. At least one power module does not work normally. At least one fan module does not work normally.
2	MST	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.	Green	Off	The switch is not a stack master.
			Green	Steady on	The switch is a stack master or standalone switch.
			Yellow	Steady on	A master election error or another type of error has occurred in the stack. NOTE: This indicator state is not supported in V100R005C00 and later versions.
3	STAT	STAT mode indicator	Green	Off	The STAT mode is not selected.
3	STAT	STAT mode indicator	Green	Steady on	The STAT mode (default mode) is selected, and service port indicators show the link connection states and link activity on ports.
4	SPEED	SPEED mode indicator	Green	Off	The SPEED mode is not selected.
4	SPEED	SPEED mode indicator	Green	Steady on	The SPEED mode is selected, and service port indicators show the speed of each port.
5	STACK	STACK mode indicator	Green	Off	The STACK mode is not selected.
5	STACK	STACK mode indicator	Green	Steady on	The STACK mode is selected, and service port indicators show the stack member ID of the local switch.
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	-	When you press the MODE button once, the SPEED indicator turns green and service port indicators show the speed of each port. When you press the MODE button a second time, the STACK indicator turns green and service port indicators show the stack member ID of the local switch. When you press the button a third time, the STAT indicator turns green (default mode) and service port indicators show the link connection states and link activity on ports. If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the STAT indicator is steady green, the SPEED and STACK indicators are off.
			ID indicator: blue	Off	The ID indicator is not used (default state).
			ID indicator: blue	Steady on	The indicator identifies the switch to maintain. The ID indicator can be turned on or off remotely to help field engineers find the switch to maintain.
7	-	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 2-351. 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.
8	-	40GE Breakout 1/2/3/4 (sequence number indicators of 10GE ports converted from a 40GE port) NOTE: Indicators 1, 2, 3, 4 turn on in cyclic order, with each indicator keeping on for 5s.	Green	Off	40GE ports are not split into four 10GE ports.
8	-		Green	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 (7 in Figure 2-171) shows the status of a 10GE port converted from the 40GE port: When Breakout indicator 1 is on, each 40GE port indicator shows the status of the first 10GE port converted from the corresponding 40GE port. When Breakout indicator 2 is on, each 40GE port indicator shows the status of the second 10GE port converted from the corresponding 40GE port. When Breakout indicator 3 is on, each 40GE port indicator shows the status of the third 10GE port converted from the corresponding 40GE port. When Breakout indicator 4 is on, each 40GE port indicator shows the status of the fourth 10GE port converted from the corresponding 40GE port. The following is an example: The first 40GE port shown in Figure 2-171 is split into four 10GE ports, and the second 40GE port is not split. When Breakout indicator 1 is on, the indicator of 40GE port 1 shows the status of the first 10GE port converted from 40GE port 1, and the indicator of 40GE port 2 still shows the status of 40GE port 2. When Breakout indicator 2 is on, the indicator of 40GE port 1 shows the status of the second 10GE port converted from 40GE port 1, and the indicator of 40GE port 2 still shows the status of 40GE port 2.
9	ACT	USB-based deployment indicator	Green	Off	USB-based deployment is disabled (default state).
				Steady on	USB-based deployment has been completed.
				Blinking	The system is reading data from a USB flash drive.
			Red	Steady on	USB-based deployment has failed.
10	L/A	ETH management port indicator	Green	Off	No link is established on the port.
				Steady on	A link is established on the port.
				Blinking	The port is sending or receiving data.
