To edit parameters, the User must enter a valid password (see Section 1: Password Entry).ETR-4000 Quick Start GuideETR-4000 Quick Start Guide Effective January 20109Enter the four-digit password as described in Section 1:Password Entry. After the password has been entered, press the “Ok” soft key.Note: The ETR-4000 utilizes atimeout function. If the timeout time has expired, the User may be asked to re-enter the password. Select the desired Phase Sequence parameter setting using the soft keys under the up and down arrows. Press the soft key under “Ok”. Save the selected parameter (see Section 2 – Saving Parameters). Note: If the time limit is exceeded, the User may need to re-enter the password.The User may change thefrequency or, if the frequency iscorrect, use the soft keys under the up or down arrows to access additional system parameters.ETR-4000 Quick Start Guide10Enter the desired CT setting using the soft keys. When the appropriate setting is displayed, follow the same procedure tochange the setting: wrench ->select/change value -> soft key under “Ok”.Press the “Ok” key. Save the selected parameter (see Section 2 – Saving Parameters). The CT pri (primary external CTsettings), CT sec (secondary external CT settings), and XCT (ground /neutral CT settings) should all be set using similar steps. When all the CT settings have been selected and saved, select the soft key under the left arrow to return to the “System Para” level.Select the soft key under the down arrow key to reach the “Protection Para” (Protection Parameter) screen.To set the protection parameters, use the soft key under the right arrow to enter the “Protection Para” menu.Use the soft key under the down arrow to select / highlight Set 1.Use the soft key under the right arrow to enter the Set 1 setting group. Set 1 is the only active setting group when the ETR-4000 is first powered up.To program currentprotection, pressthe soft key underthe right arrow while“Tdiff-Prot” ishighlighted. Thiswill display a list ofcurrent protectionsettings under“Tdiff-Prot.”Press the soft keyunder the rightarrow to enter thesettings area for 87. Congratulations! You have successfully setup the device using the front panel soft keys.Section 4:Device Setup Using PowerPort-EWhen programming the unit through PowerPort-E, start from an existing or default parameter file, or create a newparameter file. To create a new parameter file, select “Create New Parameter File” from the pull-down menu as shown on the left. This will lead to the dialog box shown below left.Select the device from the pull-down menu to load the default parameter file.A parameter file can also be loaded from a connected device by selecting “Receive Data from Device” from the “Device” pull-down menu.Note that to load parameters from the device the User may need to set up the connection to the device through the “Settings -> Connection Settings” pull-down menu.The upper left portion of the PowerPort-E screen should now display:• Operation;• System Para;• Protection Para;• Device Para;•Device Planning; and• Service.First, set up the System Parameters by double clicking on the “System Para” as highlighted to the left. This will result in the dialog box shown. When the User double clicks on a parameter within the dialog box, an interface appears that will allow the parameters to be modified.For example, to modify the Phase Sequence System Parameter, double click “Phase Sequence.” This will result in the dialog box displayed to the left. The pull-down menu will allow the User to change the Phase Sequence setting. Note that although the value has been changed, it has NOT yet been saved.The “Previous” and “Next” buttons can be used to display the Previous and Next parameters within the System Parameter list.When a value has been changed, an asterisk will appear next to the changed parameter and also next to the higher-level menu item.The asterisk next to “Phase Sequence”indicates this parameter has been changed. The asterisk next to “System Parameter” indicates a parameter contained within this set of parameters has been changed.The same procedure should be used tomodify the Differential Protection (Tdiff-Prot) Parameters, Binary Outputs Parameters, or Device Planning. The dialog box to the left is displayed, for example, by double clicking “87.” Note that four sets of Tdiff-Protsettings are available. Set 1 is usually used during normal operation. Other parameter sets can be used for abnormal operating conditions, such as to put the device into “Maintenance Mode.”From within the “87” dialog box, double click the parameter “t-Trans” to bring up the “Time of Temporary Restriction delay” dialog box. Set the value using the up and down arrows next to the time setting.As shown in the screen shot to the left, the time was changed from 2 to 3 seconds and, therefore, an asterisk appears next to both the “t-Trans” setting and the higher level “87” menu.To transfer parameters to the device, make the appropriate selection from the “Device” pull-down menu. The User has the option of downloading all settings or only those modified. Note that if settings were not originally uploaded from the device and the User downloads all parameters, then the defaults for the unmodified parameters will overwrite the parameters currently stored in the device. Transferring only modified parameters is the safer option.The pull-down allows for transfer of all parameters (including unmodifiedparameters) to the device. If the User is working with parameters that were notoriginally uploaded from the device, caution should be exercised when using this option.To download the parameters, the User must enter the password (default password is 1234). Note that until a local copy is saved to the User’s computer, the asterisksshowing modified parameters will continue to be displayed.Congratulations! You have successfully setup the device using PowerPort E.This Page Left Intentionally Blank.Contact InformationPQTSC: 1-800-809-2772Email:*******************Internet:Eaton CorporationElectrical Group1000 Cherrington ParkwayMoon Township, PA 15108United States877-ETN-CARE (877-386-2273)© 2009 Eaton CorporationAll Rights ReservedPrinted in USAPublication No. IB02602008E, Rev.

破解安装的过程很繁琐而具有挑战性，以下是安装10A432雪豹的PC安装指南，附带25张图片帮助说明.请准备必要的东西：配备Windows操作系统而且能够上网的PC雪豹安装光盘dmg镜像文件（10A432正式零售版MD5校验码是bcd4957b2f86216dddc8f1472c20f098）23G的可用空间你的勇气和耐性这个指南可能最适合从来都没在PC上安装过苹果系统的朋友，因为你不需要外加USB键盘鼠标不需要启动U盘不需要DVD刻录机（如果你已经下载有镜像甚至不需要光驱）不需要第二块硬盘和GPT分区表不需要另外一个正常运转的苹果系统（破解操作全都可以在Windows完成，不需要另外的平台）不需要输入一句又一句的命令行。

全过程快速预览：第一步，缩小当前分区，为雪豹和安装盘腾出空间第二步，加载dmg到分区并修改第三步，配置开机引导程序第四步，使用苹果光盘镜像安装雪豹第五步，启动雪豹第六步，安装后操作为方便安装，全过程需要的文件都可以在文档末尾提供的连接下载。

第一步：缩小现有分区卷雪豹使用自己的文件系统，HFS+，不兼容Windows的NTFS文件系统，这个指南需要2个HFS+分区完成安装任务，其中一个大小是6.3GB，用来放雪豹安装光盘，另一个用来放雪豹操作系统，大小是20GB（按照自己需要增减，操作系统本身就占了约4.5GB）。

为了保证你的文件不会丢失，你需要把现在的分区（如D盘），一分为三，旧文件放在一起是一个分区不受影响，分区剩下的空余空间被用来新建两个额外HFS+分区（如E盘、F盘）。

下面举例说明详细步骤，注意，我的电脑配置与你不同，下面例子只是用于说明过程和方法以帮助你理解我的意思，你需要根据自己的配置灵活变通。

Installing Ubuntu on IBM Power SystemPOWER9 servers using network bootVersion 1.0.0IBM®Quick Start Guide for installing Ubuntu on IBM Power System POWER9 serversThis guide helps you install Ubuntu on a Linux on Power Systems server.OverviewUse this information to install Ubuntu on a non-virtualized or bare metal IBM Power System POWER9 server by using the network boot servers that are provided by Canonical. This procedure follows these general steps:•Connect to the BMC firmware to set up network connection•Configure Petitboot for a network installation•Install Ubuntu from the network connection1Step 1: Completing the prerequisites and booting yourfirmwareBefore you power on the system, ensure that you have the following items:•Ethernet cable•VGA monitor. The VGA resolution must be set to 1024x768-60Hz.•USB Keyboard•Power cords and outlet for your system.If you are using the Ubuntu netboot server, the URLs are currently at the following locations:•Ubuntu 18.04: /ubuntu-ports/dists/bionic/main/installer-ppc64el/current/images/ netboot/Look for the vmlinux and initrd.gz files. If they are not available at the URLs given, then go to http:// /netboot/ and select your release > ppc64el > ubuntu-installer > ppc6el. Locate the vmlinux and initrd.gz files. If this URL is different from the paths that are given previously, record them for future use.For a list of supported distributions, see Supported Linux distributions and virtualization options for POWER8 and POWER9 Linux on Power systems.Complete these steps:•If your system belongs in a rack, install your system into that rack. For instructions, see IBM Power Systems information at https:///support/knowledgecenter/.•Connect an Ethernet cable to the embedded Ethernet port next to the serial port on the back of your system.Connect the other end to your network.•Connect your VGA monitor to the VGA port on back of system.•Connect your USB keyboard to an available USB port•Connect the power cords to the system and plug them into the outlets.At this point, your firmware is booting. Wait for the green LED on the power button to start flashing, indicating that it is ready to use. If your system does not have a green LED indicator light, then wait 1 to 2 minutes.2Step 2: Configuring the firmware IP addressTo set up or enable your network connection to the BMC firmware, use the Petitboot bootloader interface. Follow these steps:a.Power on your server using the power button on the front of your system. Your system will power on to thePetitboot bootloader menu. This process takes about 1 - 2 minutes to complete. Do not walk away from your system! When Petitboot loads, your monitor will become active and you will need to push any key in order to interrupt the boot process. Note that no boot steps are displayed until Petitboot loads.b.At the Petitboot bootloader main menu, select Exit to Shell.c.Run ipmitool lan print 1. If this command returns an IP address, verify that is correct and continue tostep 4. If no IP addresses are returned, follow these steps:i.Set the mode to static by running this command: ipmitool lan set 1 ipsrc staticii.Set your IP address by running this command: ipmitool lan set 1 ipaddr ip_address where ip_address is the static IP address that you are assigning to this system.iii.Set your netmask by running this command: ipmitool lan set 1 netmask netmask_address where netmask_address is the netmask for the system.iv.Set your gateway server by running this command: ipmitool lan set 1 defgw ipaddr gateway_server where gateway_server is the gateway for this system.v.Confirm the IP address by running the command ipmitool lan print 1 again.Note: This interface is not active until after you perform the following steps.d.To reset your firmware, run the following command: ipmitool mc reset cold.This command must complete before continuing the process; however, it does not return any information. To verify that this command has completed, ping your system BMC address (the same IP address used in yourIPMItool command). When the ping returns successfully, continue to the next step.Note: If your ping does not return successfully within a reasonable amount of time (2 - 3 minutes), try these additional steps:i.Power your system off with this command: ipmitool power off.ii.Unplug the power cords from the back of the system. Wait 30 seconds and then apply power to boot BMC. 3Step 3: Powering on your server with OpenBMC commandsNote: After your system powers on, the Petitboot interface loads. If you do not interrupt the boot process by pressing any key within 10 seconds, Petitboot automatically boots the first option.To power on your server from a PC or notebook that is running Linux, follow these steps:•Default user name: root•Default password: 0penBmc (where, 0penBMC is using a zero and not a capital O)a.Open a terminal program on your PC or notebook.b.Log in to the BMC by running the following commands.ssh root@<BMC server_ip_address>root@<BMC server password>where BMC server_ip_address is the IP address of the BMC and BMC server password is the password toauthenticate.c.To power on your server, run the following command:$ root@witherspoon:~# obmcutil powerond.Connect to OS console and use the default password 0penBmc.ssh -p 2200 root@<BMC server_ip_address>root@where BMC server_ip_address is the IP address of the BMC and BMC server password is the password toauthenticate.4Step 4: Configuring PetitbootAfter the system powers on, the Petitboot bootloader scans local boot devices and network interfaces to find bootoptions that are available to the system.Provide the network boot detail to Petitboot by following these steps:a.On the Petitboot main screen, select n to create new options.b.Choose your boot device or select to Specify paths/URLs manually and then enter your boot options:i.In the Kernel field, enter the path to the kernel. This field is mandatory. Enter a URL similar to this one for anetwork:/ubuntu-ports/dists/bionic/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/vmlinuxii.In the Initrd field, enter the path to the init ramdisk. Enter a URL similar to this one for a network: /ubuntu-ports/dists/bionic/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/initrd.gzYou can accept the defaults for the rest of the fields.c.After you set your netboot options, select OK and press Enter.d.On the Petitboot main window, select User Item 1 as your boot option and press Enter.5Step 5: Installing UbuntuAfter you select to boot the Ubuntu installer, the installer wizard walks you through the steps.a.Follow the installation wizard for Ubuntu to set up disk options, your user name and password, time zones, andso on. The last step is to restart your system.Note: The Ubuntu installation process uses DHCP by default during installation. If you are not using DHCP, youneed to configure the network manually. Follow these steps:i.On the Configuring the network with DHCP screen, click Cancel.ii.Click Continue.iii.Select Configure your network manuallyiv.Enter your IP address and select Continue.v.Enter your Netmask and select Continue.vi.Enter or confirm the gateway for your IP address and select Continue.vii.(Optional) Enter the Name server address and select Continue.viii.E nter a hostname for your system and select Continue.ix.Select a mirror of the Ubuntu archive.x.Confirm the Ubuntu archive mirror.xi.(Optional) Enter HTTP proxy information and select Continue.b.After the system restarts, Petitboot displays the option to boot the Ubuntu with Linux release number. Select thisoption and press Enter.Notes:•In Ubuntu, the opal-prd (Processor Runtime Diagnostics) package that is required for runtime detection and handling of Power processor errors on systems that are running OpenPower firmware is not installed by default.Run the following command to install this package:apt-get install opal-prdMore informationFor more information, see the following resources:•Ask Ubuntu website at /•Linux information for IBM systems at https:///BdFBGG•The Linux on Power® developer portal at Linux on Power developer portal.© Copyright IBM® Corp. 2015, 2018.

联想Z475 Ubuntu12.04LTS降温我的电脑是64位的，但是装的是32位的win7，4G的内存只能识别2.75G，看着不爽，就装了64位的Ubuntu12.04LTS，现在是双系统。

安装完成后，发现电脑发热量巨大，电脑烫手。

而且不知道是不是温度太高的关系，有时进入系统后4核的CPU只能显示出一个。

经过上网查找，用了以下方法：1.用以下四条命令将CPU的主频设置在低水平cpufreq-set -c 0 -g userspace -d 800MHZ -u 900MHZcpufreq-set -c 1 -g userspace -d 800MHZ -u 900MHZcpufreq-set -c 2 -g userspace -d 800MHZ -u 900MHZcpufreq-set -c 3 -g userspace -d 800MHZ -u 900MHZ2.用以下命令关闭独立显卡echo IGD > /sys/kernel/debug/vgaswitcheroo/switchecho OFF > /sys/kernel/debug/vgaswitcheroo/switch按照网上的说法，修改了/etc/rc.local，使开机自动关闭独显并将CPU的主频设置在低水平。

这样电脑确实没那么烫了，但是还是有点温度。

用sensors查看温度，电脑什么都不干最低温度都有40度。

后来按照电脑配置，安装了AMD官网的显卡驱动。

安装完后发现之前关闭独立显卡的命令已经无法使用了，查看显卡显示root@XXXXX:/# cat /sys/kernel/debug/vgaswitcheroo/switchcat: /sys/kernel/debug/vgaswitcheroo/switch: 没有那个文件或目录所以干脆把rc.local关掉独显的代码去掉了，不过cpufreq-set是可以用的。

然后在Catalyst Control Center里将可交换显卡设置为节能。

YLMF4下NVIDIA显卡驱动安装-补充GRUB4DOS和无RecoveryMode情况---------Winland关于引导方式的说明：不同的人有不同的安装YLMF4的方式，如果是正常情况的安装，写入磁盘MBR（主引导扇区），使用Linux的GRUB来引导YLMF，那么安装N卡驱动可以最简化，使用两条命令修改两个配置文件，然后在普通模式使用update-grub命令，接着重新启动后进入Recovery Mode命令行下，执行run驱动文件的安装，非常简单。

但是总有人搞出麻烦的系统安装方法，第一种是把Recovery Mode搞没了，所以不得不补充一下弄出全命令行登录并手动卸载nouveau模块的方法；第二种是压根不写MBR，使用Windows下的GRUB4DOS引导Linux，这种方式由于配置文件在Windows的系统C盘里面，所以要额外配置menu.lst文件。

这两种方式安装的YLMF4在安装驱动的时候也麻烦，没法简化安装过程，需要跳过下面第三部分安装操作（你操作也没用，因为不可能装得上N卡驱动），直接进入最后的第四部分进行配置和安装。

关于N卡驱动安装的说明：1、真机安装YLMF4，虚拟机没显卡，不能装驱动。

2、NVIDIA显卡驱动只适合可以单独运行的NVIDIA显卡。

3、对于最新的使用Optimus技术的NVIDIA独立显卡+Intel集成显卡的，不要安装任何NVIDIA显卡驱动，因为NVIDIA官方说明过Linux驱动不支持Optimus技术，装了NVIDIA显卡驱动后图形界面会挂掉，不如不装。

万一双显卡的挂掉了，看这里：/leejun_2005/blog/item/a033e638e13b7fe43b87ce50.htmlsudo nano /etc/X11/xorg.conf将Driver "NVIDIA"改成Driver "Intel" ，然后保存即可。
