Sure, I'd be happy to provide a detailed explanation of the correct answers to this question.
When performing maintenance or replacement on a Cisco UCS C-Series Rack-Mount Server, it is important to follow proper procedures to ensure the safety of the equipment and the technicians working on it. The following statements are true regarding powering down the server:
A. Standby power mode: Power is supplied only to the service processor and the cooling fans, and it is safe to power off the server from this mode.
This statement is true. Standby power mode is a low-power state in which power is supplied only to the service processor and the cooling fans. It is safe to power off the server from this mode, as there is no risk of data loss or damage to the equipment. To enter standby power mode, press and hold the power button for five seconds until the power status LED turns amber.
D. Graceful shutdown: Press and release the power button. The operating system performs a graceful shutdown, and the server goes to standby mode, which is indicated by an amber power status LE.
This statement is also true. Graceful shutdown is a method of shutting down the server in which the operating system is given a chance to perform a clean shutdown, saving any open files and terminating any running processes. To perform a graceful shutdown, simply press and release the power button. The server will go to standby mode, indicated by an amber power status LED.
C. Green indicates that the server is in main power mode and can be safely powered off.
This statement is true. The power status LED on the front panel of the server indicates the current power mode of the server. A green LED indicates that the server is in main power mode and can be safely powered off. An amber LED indicates that the server is in standby power mode.
Therefore, options A, C, and D are the correct answers.
Options B, E, and F are incorrect:
B. Power status LE.
This statement is incomplete and unclear. It is difficult to determine whether it is true or false without additional information.
E. Disconnect the power cords from the power supplies in your server to completely power off the server.
This statement is not recommended. While it is possible to power off the server by disconnecting the power cords from the power supplies, this method is not recommended as it can lead to data loss and damage to the equipment. It is better to use the standby power mode or graceful shutdown methods.
F. Only an emergency shutdown can be performed using the power button on the server front panel.
This statement is false. The power button on the front panel of the server can be used to perform a graceful shutdown, as well as to enter standby power mode. It is not limited to emergency shutdowns.
