A KVM Installation

After working so long, I never wrote a logbook. Flash 5 years later, the feeling is still so flat light, or, there is a job I like.
Last night to the computer room installed a KVM switch, not professional-grade, no power. Originally thought is a very simple matter, the practice discovery is actually very not simple. Or maybe I underestimated the whole process.
List The problems encountered yesterday, and the corresponding solutions.

First: The KVM line is reversed, did not fully understand the role of the KVM line, the USB power supply to the KVM, resulting in KVM does not light, or even think that the KVM is bad, until the consultation service only understand that with the USB end should be connected to the host, in order to power and control the mouse. This error is due to the lack of sufficient knowledge and understanding of the KVM line, and the loss of a significant amount of time, resulting in a loss of approximately 2 hours.

Second: think that the KVM connection line can be used, after the line is connected to the machine cabinet stitches, resulting in subsequent discovery errors, many times to re-stitch the line, the same result in a lot of scattered time loss. When tying the line to do, the system equipment test is correct, the position is determined to tie the line, reduce rework time.

Third, the power supply has electricity, but the monitor does not display. The problem has not been resolved, consulted old colleagues, the answer is that the power supply is insufficient. The problem is that the display has power, the signal is, but the monitor does not display, the power supply is a socket on the UPS. There is a plug in the normal use. This problem guidance is only resolved this morning, change the power supply is good.

Finally, KVM has electricity, and some servers show, some do not show. The problem was solved after a day. The cause is resolution. The resolution of 800x600, KVM is not very well supported. Before consulting customer service, let me connect the monitor to adjust the resolution to 1024x768, lazy no tune, until today to find some machines can show, some can not, test in the same KVM line, the same KVM interface in the case, on different servers, some display, some do not show, Thus excluding the problem I think of the line, consulting customer service, the answer is to recommend the resolution to 1024x768, adjusted, the resolution has been adjusted to the minimum 1024x768.

The above four points are the main problems when installing KVM. After this work, found a lot of problems, analysis problems are not programmed, work more blind, resulting in a lot of rework, time wasted.

Do not complete the work, the use of wireless mouse is not tested, tomorrow test.

Through this opportunity, strive to develop the habit of writing a diary, the work encountered problems recorded. To learn.

Thank you for the Lei general friendship support, and maxtor dimensional moment that unknown customer service to me the trouble of technical support.

The article wrote no technology, the whole work is not technology, please the great God do not laughed at.
