Troubleshooting The Enclosure

NOTE: For troubleshooting information on the blades in your enclosure, see the blade documentation at support.dell.com/manuals.

Safety First—For You and Your System

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

Responding to a Systems Management Alert

Message

The CMC management applications monitor critical system voltages and temperatures, and the cooling fans in the system. For information about the CMC alert messages, see the CMC User's Guide at support.dell.com/manuals .

Troubleshooting A Damaged Enclosure

1. Ensure that the following components are properly installed and connected:

• CMC module

• iKVM module

• I/O modules

• Power supply modules

• Fan modules

• Blades

• Sleeves (with quarter-height blades)

2. Ensure that all cables are properly connected.

3. Ensure that all components are properly installed and free from damage.

4. Run the online diagnostics.

If the tests fail, see

Troubleshooting A Wet Enclosure

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

1. Turn off the system.

2. Disconnect the power supplies from the PDU.

CAUTION: Wait until all of the indicators on the power supplies turn off before proceeding.

3. Remove all of the blades/sleeves.

4. Remove the following components from the enclosure: a) Power supply modules b) Fan modules c) CMC module(s) d) iKVM module e) I/O modules

5. Let the system dry thoroughly for at least 24 hours.

NOTE: Air dry and do not use towels.

6. Install the following components in the enclosure: a) I/O modules b) iKVM module c) CMC module(s) d) Fan modules e) Power supply modules

7. Install the blades/sleeves.

8. Reconnect the power supply modules to their PDU and start up the system.

If the system does not start up properly, see Getting Help

.

9. Run the Server Administrator diagnostics to confirm that the system is working properly.

If the tests fail, see

Getting Help

.

Troubleshooting Power Supply Modules

NOTE: The power-supply modules are hot swappable. Remove and replace only one power-supply module at a time in a system that is turned on. Leave a failed power-supply module installed in the enclosure until you are ready to replace it.

Operating the system with a power-supply module removed for extended periods of time can cause the system to overheat.

NOTE: A 2700 W power supply module requires 110 V to 240 V input from an AC power source. If a power supply module is plugged into a 110 V electrical outlet, the power supply operates at 1350 W, if you select the Allow 110 VAC Operation check box in the CMC Power Configuration screen.

1. Locate the faulty power supply module and check the indicators. The power supply's AC indicator is green if AC power is available. The power supply's fault indicator is amber if the power supply is 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.

Troubleshooting I/O Modules

NOTE: To eliminate the possibility of a hardware problem with the module or its attaching devices, first ensure that the 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-height blade connects to two I/O ports on the two associated I/O modules.

3. Using the "17th blade" feature of the CMC, use the Connect Switch-X command to verify that the switch is fully booted, and verify the switch’s firmware revision and IP address.

4. Verify that the switch module has a valid IP address for the subnet. Verify using the ICMP ping command.

5. Check the network connector indicators on the network switch module:

• If the link indicator displays an error condition, check all cable connections.

• Try another connector on the external switch or hub.

• If the activity indicator does not light, replace the network switch module.

6. Using the switch management interface, verify the switch port properties. If the switch is configured correctly, back up the switch configuration and replace the switch. See the switch module documentation for details.

7. If the blade requires a mezzanine card for a particular network switch module, ensure that the appropriate mezzanine card is installed.

If so, reseat the mezzanine card. If the network link indicator on the blade is green, then the blade has a valid link to the appropriate network switch module.

8. Ensure that the appropriate operating system drivers are installed and that the protocol settings are configured to ensure proper communication.
