The commonly described 'system boot' actually involves multiple stages:
BIOS Power On Self Test (POST): including memory testing and testing of keyboards, hard drives, and IDE drives.
Loading ROM program: Each device may load its running code or ROM program into memory, so that users can see some devices installed in the system, such as SCSI cards.
Operating system boot: During this period, the operating system takes over the server and performs various checksum settings required for operation. For example, in Windows NTh, it appears as a "blue screen".
Any slow speed in any of the above three points will make users feel that the startup is slow. The following are possible reasons for slow startup:
➢ Large configured memory capacity: Installing a high-capacity memory system may take 1-2 minutes to detect. When executing services that require multiple restarts, the extended memory test can be turned off during BIOS startup to accelerate the startup pro

When the server system is powered off, it saves the latest working status of the power supply. If the AC power is accidentally disconnected before using the power button on the front control panel to turn off the system, once the AC power is reconnected, the system will automatically attempt to return to the previous "on" state.
Please remember that unplugging the system power cord or pressing the switch on the socket will cut off the AC power supply. Cut off power in the correct order: First press the power off button on the front control panel, then unplug the AC power cord. You may use the power button on the front control panel to fully power up the system, and then turn off the system to solve this problem.
If the problem still cannot be solved, please record the following issue in detail before calling the customer support engineer: What is the version number of the BIOS used in the system? What is the memory used? Is this memory in the manufacturer's specifi

Please check the following items:
Is the keyboard working properly? Check if the Num Lock light is locked.
Is the connection cable of the monitor securely plugged in and is the power on? Many monitors now automatically turn off when not in use, and require a period of warm-up when activated.
Is the brightness and contrast of the monitor adjusted appropriately?
Is the setting of the monitor correct?
Is the signal line of the monitor installed correctly?
Can the onboard video controller function properly?
If the system uses an external display expansion card, please check according to the following method:
➢ Verify that the graphics card is fully inserted into the slot on the motherboard (and verify that the monitor is securely connected to the graphics card).
Restart the system for the new settings to take effect.
If the system restarts and there are still no characters on the screen after POST emits a beep, record the beep you hear. This information is ver

Please check the following items:
If the system operates normally but there is no buzzing, there may be a problem with the speaker. If the speaker is functioning properly but not working properly, please contact technical support personnel or authorized dealers for assistance.
To ensure accurate judgment by technical personnel and obtain high-quality support, please provide a detailed POST of the beep code generated during the self check process before requesting technical support.

Please check the following items:
Are all power cords securely plugged in? Is the power cord connected to the junction box or socket? Is your fuse or safety device damaged? Have you tried changing the power cord?
Is the system operating normally? If it is normal, there may be a problem with the power indicator light, or the cable from the front board to the motherboard may be loose. If all inspection items are normal but the problem still persists, please contact technical support personnel or authorized dealers for assistance.

1. Server expansion
Trial testing in the actual operating environment before formal deployment will help enterprises determine the number of users that the host cluster can support. During the trial period, it is necessary to simulate daily operations, which can help enterprises realize what kind of servers they need to deploy to support the expanded number of users. Using automated load simulation does not represent real users, and using simulated data may result in VDI deployment not achieving the expected results.
When deploying small-scale VDI, only one virtual host may be needed. When the scale expands, should the next host be placed in the same rack or should different power supply units be used? In large-scale environments, clusters may be built within a blade chassis - as the scale expands, new blade chassis can be purchased to construct a new cluster. Do new and old clusters need to be located in different isolation zones? These issues need to be carefully considered.
