NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supplyand determine whether it is working properly. The power supply DC power indicator turns green if the powersupply is functioning properly.3. If none of the power supplies show a fault LED and the blades do not power on, check the LCD display or CMC forstatus messages.4. If the problem is not resolved, see Getting Help.Troubleshooting Fan ModulesNOTE: The fan modules are hot swappable. Remove and replace only one fan module at a time in a system that isturned on. Operating the system without all six fan modules for extended periods of time can cause the system tooverheat.1. Locate the faulty fan. Each fan module has indicators that identify a faulty fan.2. Remove the fan module.3. Examine the blades for debris. If debris is present, carefully remove it.4. Reseat the faulty fan.5. If none of the fans show a fault LED and the blades do not power on, check the LCD display or CMC for statusmessages.6. If the problem is not resolved, install a new fan.7. If the new fan does not operate, see Getting Help.Troubleshooting The iKVM ModuleWhen using iDRAC video\console redirection, and you cannot see video through the iKVM when you switch to a bladerunning Linux, a typical cause is that a monitor or KVM appliance with a lower resolution has recently been added.For example, a blade running X Windows under Linux is inserted and powered on. A user connects to the blade in OSGUI mode using the iDRAC and a video resolution is detected and hard-set for that session. A monitor or KVM applianceis attached to the front or rear iKVM interface on the M1000e enclosure. The monitor or the KVM appliance is configuredwith a resolution LOWER than the currently configured resolution in the X-Window session on the Linux blade. Whenyou select the Linux blade using the front or rear port on the iKVM, the iDRAC circuit adopts the lower resolution of theexternal connected devices. The video on the lower resolution monitor or the KVM appliance is not displayed until XWindows is restarted (iDRAC video should still be viewable.)1. From the iDRAC session, exit and re-enter GUI mode. The lower resolution is communicated and utilized.2. Set all monitors or KVM appliances connected to the M1000e enclosure to the same resolution or higher asconfigured on the Linux blades in GUI mode.3. From the lower resolution monitor (no video displayed) press to change to the non-GUI loginscreen.4. Restart X Windows to detect and utilize the lower resolution.Troubleshooting I/O ModulesNOTE: To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure thatthe module is properly initialized and configured.1. Check that you have installed the module in an I/O slot that matches its fabric type.2. Check that the pass-through module or switch ports are cabled correctly. A given mezzanine card in a full-heightblade connects to two I/O ports on the two associated I/O modules.93
