A UPS is designed to provide enough power to shut a system down safely during an extended power outage. Most are not intended as long-term power solutions. The UPS connects to the power source (usually a wall socket), the computer plugs into the UPS, and

the UPS is connected through a serial or USB port to the computer. Software on the computer uses this connection to monitor battery life and to detect when the regular power is lost. You can configure the software to shut the system down automatically when the battery charge reaches a certain level. You usually need to configure the following settings when working with UPS software: o Time to wait before sending a warning to clients o Time to wait before beginning a shutdown o Name of programs or commands to run during shutdown In addition to providing power when the power is lost, most UPS systems also condition the line and remove power spikes and sags. Most UPS devices sound an alarm when the AC power is lost. This alarm continues until AC power is restored, although many UPS devices have a switch to mute the alarm. During certain conditions, such as an electrical storm or when the power supply is constantly going up or down, you might need to unplug the computer to protect it. Simply turning it off might still damage the components because some power remains supplied to the system. In the case of an electrical storm, keeping the system plugged in leaves it susceptible to power spikes. Troubleshooting Process 0:00-3:21 In this lesson, we're going to talk about using a systematic troubleshooting process. Now, understand that being a good troubleshooter is a key part of being an effective system administrator. Now, I've been teaching new system administrators for many years now, and this is actually one of the hardest skills for some folks to master. Some admins just seem to have an intrinsic sense for how to troubleshoot problems, but others just don't. And the reason for this, in my opinion, is that troubleshooting is part art. Just as it's difficult for some of us, including me, to learn how to draw, sculpt or paint, it's also difficult for some of us to learn how to troubleshoot computer problems. However, I've noticed that with a little training and a lot of practice, most new administrators can eventually learn how to troubleshoot very effectively. And there are three keys to doing this. Number one, you need to use a solid troubleshooting procedure. Number two, you need to obtain a working knowledge of various troubleshooting tools.And then, number three, you have to gain a lot of experience troubleshooting computer problems.Now, the last point is beyond the scope of this course. The only way to gain troubleshooting experience is to actually spend years working in the field. Computer problems can be caused by a wide array of different issues, and we can't even begin to cover all of them here. Instead, in this lesson, I want to focus on using a standardized process for troubleshooting computer issues. By using a standardized process, you can adapt to, confront, and resolve a very broad range of problems. Now, the model I'm going to present here is by no means all-inclusive. You may need to add, remove, or

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
