Note: Lenovo qitian m715e installs the hard drive Protection System and transmits data through the network

It is still a student. Although there are few senior students and the lab is not diligent, the instructor has something to say and should do well.

Instructor Shen Rongsheng, director of the software lab, the school gave two data centers, one 70 Lenovo Kai Tian m715e, and one 30 new + 70 new hosts (with vintage display ), my classmates installed common software and systems in Xiaoshan, and sent 70 old machines through Lenovo's network. Then they went home. It would have been a big problem for me to share the rest of the machine with me, but it was not so smooth. Otherwise, I would not have noted down the value.

1. Unable to access Lenovo hard drive protection system (Press F4.) or cannot access Lenovo Network

When you press F4. you may enter the Lenovo hard disk protection system. If you are a Lenovo machine, you may press other shortcut keys, but the system does not respond. It may be because the Lenovo hard disk protection system has broken you, or unload it.

Or when you buy your machine, you do not have a hard disk protection system installed, but directly install Linux, such as Ubuntu, and it will be stuck on the Lenovo network simultaneous transmission interface.

Solution: reinstall the Lenovo hard disk protection system.

If this problem occurs during the service period, Lenovo engineers can be asked to maintain it free of charge. However, after the maintenance period expires, Lenovo engineers will be charged on their own!

The actual practice is very keyboard, Lenovo hard disk protection system can be made into a boot disk, such as a USB flash disk, boot into the boot disk, will enter a PE system, before installing Lenovo hard disk protection is recommended to uninstall first.

Then, based on your Lenovo protection system version, select the appropriate installation file to install the Lenovo hard disk protection system, such

Installation command for version 7.5: eduxp. bat

Installation command for version 7.0: setup. bat

The new version is basically version 7.5, and edu7.5.iso cannot be found on the Internet, because the 7.5 system has been out for less than half a year. Of course, people will not give it to you, if you need it, you can email it to me!

Version 7.0 can be downloaded online. Search for it by yourself.

2. Why is the speed of the Lenovo network slow?

In this case, the receiver can connect to the sender, but the sender cannot send data to the receiver.

The reason is very simple, because the new data center uses the new ruijie switch, and the ruijie switch enables storm broadcast control by default, so you need to disable storm broadcast control on the LAN!
