Interpreting Power Supply LED Indicators on Dell PowerEdge Servers

Server Troubleshooting (32%)

Analyze the visual indicators on server components - system ID, PSU, and BLINK

Understanding PSU LED Blink Patterns

The Power Supply Unit (PSU) on Dell PowerEdge servers uses LED indicators to communicate status information. The color and blinking pattern of the LED signify different conditions:

Solid Green Light

PSU is functioning normally.

Blinking Amber Light

Indicates a warning or fault condition.

Specific Blink Pattern:

Blinking Amber for Two Seconds On, One Second Off

Indicates a Mismatch Voltage Condition.

Explanation of Options

Option A: Faulted state

Explanation: A faulted PSU typically shows a solid amber light, not a blinking pattern.

Conclusion: Incorrect.

Option B: Firmware update

Explanation: During a firmware update, the PSU LED may blink, but usually with a different pattern or color (often green).

Conclusion: Unlikely to cause the specified blink pattern.

Option C: Mismatch voltage

Explanation: The blinking amber pattern of two seconds on and one second off indicates that there is a voltage mismatch between redundant power supplies or an input voltage issue.

Possible Causes:

PSUs of different wattages installed.

PSUs connected to power sources with different voltages.

One PSU not receiving power or connected to an incompatible power source.

Conclusion: Correct Answer.

Server Troubleshooting (32%)

Analyze the visual indicators on server components: Understanding PSU LED indicators is essential for diagnosing power-related issues.

System Administration (18%)

Verify health status: Regular monitoring of server components ensures timely identification and resolution of issues.

Conclusion

A blinking amber PSU LED with a pattern of two seconds on and one second off signifies a mismatch voltage condition. This requires checking the power supplies to ensure they are identical and connected to compatible power sources.

To change the Power Supply Unit (PSU) configuration to a 2+0 setup with PSU2 as the primary in the iDRAC interface, follow these steps:

Step-by-Step Guide:

Navigate to Power Management Settings:

In the iDRAC interface, go to the Configuration tab at the top.

Select Power Management from the dropdown options.

Locate the Power Configuration Section:

Within the Power Management settings, look for a section labeled Power Configuration or Power Supply Configuration.

Select the Redundancy Policy:

Change the Redundancy Policy to 2+0. In this configuration, there will be no redundancy, and both power supplies will be active but configured as independent power sources without failover.

Set PSU2 as the Primary PSU:

Locate the option to designate the Primary PSU. Select PSU2 as the primary power source.

This setting ensures that PSU2 will handle the primary power load under normal conditions.

Apply and Save Changes:

Once you have made these changes, click Apply or Save to confirm the new configuration.

The interface may prompt for confirmation, after which the settings will be saved, and PSU2 will become the primary power supply under a 2+0 configuration.

Verify Configuration:

Review the updated settings to confirm that PSU2 is now set as primary and that the redundancy policy is 2+0, meaning only PSU2 is actively providing power without a secondary backup.

By following these steps in the iDRAC simulator, you will set up PSU2 as the primary power source with no redundancy, ensuring a 2+0 configuration. This setup will leverage PSU2 exclusively without automatic failover to another power supply.

 Launch the Simulator:

Open the PowerEdge iDRAC simulator to access the user interface and perform the required task.

 Navigate to System Information:

In the top menu bar, select the "Configuration" tab.

From the options that appear, choose "Storage". This section will display details and configurations for the storage controllers installed on the server.

 Check the H965i Storage Controller:

Locate the H965i storage controller in the list. Selecting it should bring up a summary page with various specifications for the controller.

Look for the field labeled "Cache Memory Size". This will provide the cache memory size value for the controller.

Understanding Granular User Privileges in iDRAC9

Granular User Privileges in iDRAC9

iDRAC9 provides the ability to assign specific privileges to user accounts, allowing for fine-grained control over what actions users can perform.

Explanation of Options

Option A: Access virtual console

Explanation: Access to the virtual console is a specific privilege that can be granted or denied to individual users in iDRAC9. This allows administrators to control who can remotely access the server's console.

Conclusion: Correct Answer.

Option B: Readonly

Explanation: The Readonly privilege is a role that allows users to view settings without making changes. It is not considered a granular privilege but a predefined user role.

Conclusion: Not as granular as specific privileges.

Option C: Edit logs

Explanation: iDRAC9 does not provide a specific privilege to edit logs, as logs are critical records that should not be altered for security and auditing purposes.

Conclusion: Incorrect.

Option D: Change dashboard view

Explanation: Changing the dashboard view is a user interface preference and not typically a privilege that is controlled or assigned in iDRAC9.

Conclusion: Incorrect.

Conclusion

Access virtual console is a granular user privilege configurable in iDRAC9, allowing administrators to control remote console access on a per-user basis.

To create and save a server configuration profile with specific components in the iDRAC interface, follow these steps:

Step-by-Step Guide:

Access Configuration Profiles:

Go to the "Configuration" tab on the top menu bar.

From the dropdown options, select "Server Configuration Profile."

Create a New Profile:

Within the Server Configuration Profile section, choose the option to Create a New Profile.

You will likely see options to specify which components to include in the configuration profile.

Select Components:

When prompted, select only the components required for the configuration:

NIC: Network Interface Card settings.

RAID: Storage controller and RAID configuration.

iDRAC: iDRAC management settings.

Ensure that other components are not selected to meet the requirement.

Save the Configuration:

Enter the file name "PE-server" for the profile.

Choose the option to Save or Export the configuration profile. This should save the configuration to the specified name, typically on the server or local storage available through iDRAC.

Verify the Profile Creation:

After saving, verify that the profile appears in the list of server configuration profiles with the name "PE-server."

Confirm that it includes only the selected components.

By following these steps, you should successfully create and save the configuration profile with the specified components.
