Checking configurations of an S series switch
You can run the following commands to check configuratio of an S series switch (except the S1700): 1. Run the display current-configuration command to check the current valid configurations. This command does not display parameters that use default settings. 2. Run the display saved-configuration command to check the configuration file to be used for the next startup. 3. Run the display startup command to check the system software, backup system software, configuration file, license file, patch file, and voice file for the current and next startup.

How to check the status of AP on the S switch?

Backup of dual power slots on S series switches
Support of power slots on S series switches is as follows: 1. The switches that have PWR in their names (except the S2700-9TP-PWR-EI, S2750-20TP-PWR-EI-AC, S2750-28TP-PWR-EI-AC, S2751-28TP-PWR-EI-AC, S5700-PWR-LI, S5720-PWR-LI, and S5720S-PWR-LI series) support dual PoE power modules. 2. The switches that have C or PC in their names support dual power modules. 3. The S5720-SI series support dual power modules (except the S5720-14X-PWH-SI-AC, S5720-28X-SI-24S-AC, S5720-28X-SI-24S-SC, and S5721-28X-SI-24S-AC). When a switch has dual power modules installed: - For a PoE switch, the two power modules work in 1+1 redundancy mode to provide power for the chassis and provide power for PDs in load balancing mode. - For a non-PoE switch, the power modules provide power for the chassis in 1+1 redundancy mode. You can use Hardware Query Tool to query details.

Checking the restart reasons of an S series switch
the display reboot-info command to check restart reasons of S series switches (except S1700 switches). A switch may be restarted due to one of the following reasons: MANUAL: It is restarted by using the reboot command. POWER: It is restarted after being powered off. SCHEDU: It is restarted by using the schedule reboot command. OTHER: It is restarted due to either of the following reasons: 1. It is power recycled instantly, for example, the power cable is in bad contact or transient overvoltage and loss of voltage occurs. In this case, check whether the power cable is correctly connected to the switch. 2. An exception occurs in the system.

If SCHEDU or MANUAL is displayed in the command output, the switch is normally restarted. If POWER or OTHER is displayed, check whether any other devices using the same power supply system have reboot records around the time when the switch is restarted. If such reboot records are found, the switch's restart is caused by exceptions in the external power supply system. If no such reboot record is found, go to the next step . If the switch uses pluggable power modules, replace the power modules with power modules that can work normally to determine whether the power modules are faulty. If the switch uses built-in power modules, collect required information and contact Huawei technical support personnel if the external power supply system works properly. The information includes the outputs of the display version, display device, display reboot-info, display alarm urgent, and display power commands. (If pluggable power modules are used, the output of the display power command is not required.)
