 Issue Description
Symptom: The fan of S9303 V100R001C02B118 operates at full speed. When a command is used to adjust the rotating speed manually, the system displays that the operation fails because alarms exist. View the system alarms. Temperature alarms of the main board exist. Detailed information is shown below.

---------------------------------------------------------------------------- 
 
transparent.gif Handling Process
1. Run the disp cdev slot 5 commands in the hidden view. The information displayed shows that the board type BoardExtType is 3. This is the correct board type. 
2. Run the dis dsms variable slot 5 command in the hidden view. At this time, BoardExtType is 7 and needs to be modified. 
3. Change the type of the main board by using the set boarded slot-id type-id command. 
[S9303-hidecmd]set boardid 5 3 
4. Rest the CBUS of the board by using the reset cbus slot slot-id cold command. 
[S9303-hidecmd]reset cbus slot 5 cold 
5. After the main board is reset, view the alarms. If the alarms disappear, perform step 7. If not, perform step 6. 
6. Update the CBUS software and the SDR file. 
<S9303>upgrade slavempu jtag startup canbus_app 
<S9303>upgrade slavempu jtag startup canbus_sdr 
7. Alarms disappear and the fan can adjust the rotating speed automatically. The rotating speed is automatically adjusted to 27%. 
 
transparent.gif Root Cause
1. The slave main board in slot 5 is configured with an incorrect board type. As a result, the configuration file of the CBUS is incorrect and temperature alarms appear. 
2. When temperature alarms exist, the fan operates at full speed and the rotating speed cannot be adjusted manually. 
3. Set the board type to the correct one and reset the CBUS. After that, temperature alarms disappear and the fan speed is adjusted automatically. 
 
transparent.gif Suggestions
The fan or fans must operate at full speed when temperature alarms exist. Sometimes, temperature alarms appear due to other reasons and you need to remove the abnormal alarms. After that, the fan speed becomes normal.

To view information about built-in fans, run the display fan command. A device has no fan subcard but has built-in fans if both of the following situations occur:

    No fan information is displayed when you run the display device command.
    The Online field displays Present when you run the display fan command.

The following is an example of the command output.

The fan or fans must operate at full speed when temperature alarms exist. Sometimes, temperature alarms appear due to other reasons and you need to remove the abnormal alarms. After that, the fan speed becomes normal.  To be honest it is very difficult to find out this kind of issue, but you did.  thanks for sharing us such a good example, I love you!

Thanks for you sharing , about the key information .
1. The slave main board in slot 5 is configured with an incorrect board type. As a result, the configuration file of the CBUS is incorrect and temperature alarms appear.
2. When temperature alarms exist, the fan operates at full speed and the rotating speed cannot be adjusted manually.
3. Set the board type to the correct one and reset the CBUS. After that, temperature alarms disappear and the fan speed is adjusted automatically.

The fast growth of network technologies brings challenges to network security and Quality of Service (QoS). ACL is a security policy that is enforced on networks to prevent the following problems:
  • To prevent information leaks and unauthorized access of resources on key servers of an enterprise network

  • To prevent viruses on the Internet from entering and spreading on the enterprise intranet

  • To prevent random services from occupying network bandwidth, thereby guaranteeing bandwidth for delay-sensitive services such as voice and video

     check the configuration of the DHCP server and the associated device port to see if it is configured correctly. And check the steps as following:

whether the connection between AP and AC is good;

whether the APs have created management VLANs on each device that is connected to the AC;
