Data Switch (CE8850-32CQ-EI)
Data switches provide a high bandwidth and low latency to connect controller enclosures for their control information exchange and service data flows. They are typically used for connections between multiple controller enclosures when:
- The storage system is installed for the first time. For detailed connection diagrams and configurations, see the Installation Guide corresponding to your product model.
- The storage system capacity is expanded. To expand the capacity of storage components, contact the technical support center.
The switches used for controller expansion can be deployed on a scale-out network only, not for front-end service networking or other purposes.
Indicators
The following figures and tables show and describe the indicators on a data switch.
No. |
Indicator |
Name |
Color and State |
Meaning |
|---|---|---|---|---|
1 |
SYS |
System status indicator |
Green, off |
The system is not running. |
Green, blinking fast |
The system is starting. |
|||
Green, blinking slowly |
The system is running normally. |
|||
Red, steady on |
|
|||
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. |
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. |
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. |
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 |
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. |

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 4-96. 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 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. |
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 port indicator (7 in Figure 4-221) shows the port status:
The following is an example: The first 40GE port shown in Figure 4-221 is split into four 10GE ports, and the second 40GE port is not split.

Green, off |
USB-based deployment is disabled (default state). |
Green, steady on |
USB-based deployment has been completed. |
|||
Green, blinking |
The system is reading data from a USB flash drive. |
|||
Red, steady on |
USB-based deployment has failed. |
|||

ETH management port indicator |
Green, off |
No link is established on the port. |
Green, steady on |
A link is established on the port. |
|||
Red, blinking |
The port is sending or receiving data. |
