Understanding the Black Strap on the Power Supply Handle

Server Components (26%)

Identify power options and redundancy features, thermal features, and liquid cooling

Explanation of Power Supply Straps

Dell PowerEdge servers often use black straps on power supply units (PSUs) to indicate certain attributes of the PSU. The color of the strap can help identify specific features or categories of the power supply.

What Does "NAF" Mean?

NAF stands for Non-Redundant, Auto Failover.

This indicates that the PSU is part of a non-redundant configuration, but it is capable of automatic failover in the case of power loss.

This is typical in systems with multiple PSUs, where each PSU can take over if the other fails.

Why Not Other Options?

Option A: PSU

The strap does not indicate that the device is just a PSU; rather, it indicates a specific feature of the PSU.

Option C: RAF

RAF stands for Redundant Auto Failover, which is not the correct feature indicated by the black strap.

Option D: Spare PSU

The strap does not indicate that the PSU is a spare unit.

Conclusion

The black strap on the power supply handle indicates that the PSU is NAF (Non-Redundant, Auto Failover). This means it is part of a non-redundant system but capable of automatic failover.

Entering BIOS Progress Mode on a Non-Responsive Dell PowerEdge R660 During POST

Server Troubleshooting (32%)

Explain Configuration Validation, crash capture, and minimum to POST

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

Understanding the Scenario

Server Model: Dell PowerEdge R660

Issue: Not responding during POST (Power-On Self-Test)

Objective: Enter BIOS Progress Mode to troubleshoot the issue

What is BIOS Progress Mode?

BIOS Progress Mode is a diagnostic feature that allows the system to display detailed POST codes and progress indicators during the boot process. This can help administrators identify where the boot process is stalling.

How to Enter BIOS Progress Mode

Method: Press and hold the System ID button for more than five seconds during the boot process.

Effect:

Forces the server into BIOS Progress Mode.

Displays detailed POST information on the screen.

Helps in diagnosing issues that prevent the server from completing POST.

Explanation of Options

Option A: Press and hold the power button for 15 seconds.

Analysis:

Holding the power button for an extended period typically forces a hard shutdown or initiates a power reset.

Does not help in entering BIOS Progress Mode.

Conclusion: Incorrect.

Option B: Enter <F2> when the server tries to POST.

Analysis:

Pressing during POST is the standard method to enter the BIOS Setup Utility.

However, if the server is not responding during POST, this method may not be effective.

Does not specifically enable BIOS Progress Mode.

Conclusion: Less effective.

Option C: Press and hold the System ID button for more than five seconds.

Analysis:

Pressing and holding the System ID button for over five seconds triggers the server to enter BIOS Progress Mode.

This method is designed for situations where the server is unresponsive during POST.

Conclusion: Correct Answer.

Option D: Disconnect and reconnect the power cables for both PSUs.

Analysis:

Power cycling the server by disconnecting and reconnecting power may not resolve POST issues.

Does not enable BIOS Progress Mode.

Conclusion: Unlikely to help.

Configure BIOS, Storage, virtual media, networking, user access, lockdown mode, and group management:

Familiarity with BIOS access methods and diagnostic tools is crucial for system administrators.

Conclusion

When a Dell PowerEdge R660 server is not responding during POST, pressing and holding the System ID button for more than five seconds will force the server into BIOS Progress Mode. This allows the administrator to see detailed POST codes and identify where the boot process is failing.

To generate and save a SupportAssist collection with system information and debug logs only in the iDRAC UI, follow these steps:

Step-by-Step Guide:

Access SupportAssist in iDRAC:

In the iDRAC interface, navigate to the Maintenance tab in the top menu.

From the dropdown, select SupportAssist. This will bring up the SupportAssist options.

Initiate a Collection:

In the SupportAssist section, look for the option to Create a New Collection or Start a Collection.

Choose Collect System Data or Generate a Collection, depending on the version of iDRAC.

Select Collection Components:

When prompted to select components for the collection, check the boxes for System Information and Debug Logs only.

Ensure no other components are selected to limit the collection to just the required data.

Start the Collection:

Confirm your selection, then click Start or Generate. This will initiate the process to gather the specified data from the system.

Save the Collection Locally:

Once the collection is complete, you should see an option to Download or Save the file.

Click the download link and save the collection file locally on your computer.

Verify the Collection File:

Check the downloaded file to ensure it contains only the system information and debug logs. It should be in a format such as ZIP or TAR, depending on the system configuration.

By following these steps, you can successfully generate a SupportAssist collection with just the system information and debug logs and save it to your local system for further review or support purposes.

To investigate a power issue on a specific date, such as April 30, 2022, the system administrator should examine the iDRAC logs for entries related to power supply faults or failures. Here's how to approach finding the correct answer:

Step-by-Step Approach:

Access the System Logs:

In the iDRAC interface, navigate to the Dashboard tab.

Scroll down to the Recent Logs section or navigate to System Logs under Maintenance or iDRAC Settings (depending on the iDRAC version) to access detailed logs.

Filter Logs by Date:

Use the filter option to specify the date, focusing on entries from April 30, 2022. This will help narrow down relevant events.

Identify Power-Related Entries:

Look for log entries that mention power supply issues or voltage faults around the specified date. In this case, entries related to under-voltage faults or power supply failures will be critical.

Interpret the Log Entries:

Based on typical power fault logs, consider the possible answers:

A. Under voltage fault detection on power supply 1: Indicates a voltage issue was detected on PSU1.

B. Power supply 2 has failed: Indicates PSU2 has completely failed.

C. Under voltage fault detected on power supply 2: Indicates a voltage issue was detected on PSU2.

D. Power supply 1 has failed: Indicates PSU1 has completely failed.

The specific log entry depends on the exact wording in the logs. However, from the options provided, if the administrator received a notification about a power issue, the most likely scenario involves a failure or under-voltage detection.
