SK0-005 server-hardware-installation-management Practice Question
After a brief power outage, a server does not power on when the power button is pressed. The power supply LED indicator is green, but the internal fans do not spin and there is no video output. Which of the following is the MOST appropriate troubleshooting step?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check that the 24-pin ATX power connector is securely connected to the motherboard.
A green LED indicates standby power is present. If the system does not fully power on, the primary power delivery from the PSU to the motherboard may be disrupted, often by a loose connector.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Test the system with a known-good CPU.
Why it's wrong here
CPU failure is rare and would not explain the absence of fan spin or the specific post-outage scenario. Checking power connections is more logical.
- ✗
Reset the server's configuration via the CMOS jumper.
Why it's wrong here
A power outage might reset CMOS, but the symptom of no power at all (no fan spin) points to a physical power issue, not a configuration problem.
- ✓
Check that the 24-pin ATX power connector is securely connected to the motherboard.
Why this is correct
Power surges can loosen connectors. Reseating the main power connector is a quick, non-invasive step that often resolves such failures.
- ✗
Replace the power supply.
Why it's wrong here
A green LED suggests the PSU is not completely failed. A loose connection is more likely than a full PSU replacement at this stage.
