faulty. If no indicators are lit, ensure that 208 V AC power is available from the PDU and that the power cable is properly connected to the power supply module.

2.Install a new power supply.

NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is working properly. The power supply DC power indicator turns green if the power supply 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 for status messages.

4.If the problem is not resolved, see Getting Help.

Troubleshooting Fan Modules

NOTE: The fan modules are hot swappable. Remove and replace only one fan module at a time in a system that is turned on. Operating the system without all six fan modules for extended periods of time can cause the system to overheat.

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 status messages.

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 Module

When using iDRAC video\console redirection, and you cannot see video through the iKVM when you switch to a blade running 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 OS GUI mode using the iDRAC and a video resolution is detected and hard-set for that session. A monitor or KVM appliance is attached to the front or rear iKVM interface on the M1000e enclosure. The monitor or the KVM appliance is configured with a resolution LOWER than the currently configured resolution in the X-Window session on the Linux blade. When you select the Linux blade using the front or rear port on the iKVM, the iDRAC circuit adopts the lower resolution of the external connected devices. The video on the lower resolution monitor or the KVM appliance is not displayed until X Windows 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 as configured on the Linux blades in GUI mode.

3.From the lower resolution monitor (no video displayed) press <CTRL><ALT><F3> to change to the non-GUI login screen.

4.Restart X Windows to detect and utilize the lower resolution.
