Hardware Problems On some servers, operation of the Diagnostic Adapter with both USB and PS/2 devices simultaneously connected to the server can cause errors within the operating system including an inadvertent shutdown. If this occurs, switch the PS/2 devices on your system to USB devices. Integrated Management Display If the server has an Integrated Management Display (IMD), perform the following actions to make sure it is working: • Be sure that the IMD backlight is on. - If the IMD backlight is not on, check the IMD cable to be sure that it is not damaged and that it is properly connected. - If the IMD backlight is on, check the IMD contrast. You can adjust the level of contrast on the IMD by using the up and down arrows. Press the up arrow key to increase the contrast, and press the down arrow key to decrease the contrast. For further information, refer to your server-specific user documentation. • If the IMD displays the LCD Error XX message, check to be sure that the cable is firmly plugged in. If firmly plugging in the cable does not remove the error message, then replace the IMD. • If there is a monitor, check the screen for messages. Hot-Plug Management Module If you are having problems with a server enclosure or power enclosure Hot-Plug Management Module, check the following: • Check the module LEDs to see if you can isolate the problem. Refer to your server-specific user documentation for more information. • Check to be sure that there are no loose or disconnected cables, and that all connections are properly seated. 2-40 HP Servers Troubleshooting Guide
