Symptom Action
Power supply - squealing,
scratching, or grinding noise.
1.
If the server is running redundant power, pull and replace each power supply,
one at a time, to determine which power supply is causing the noise.
2. If a single power supply is identified as causing the problem, complete the
following steps:
a. Make sure that the power supply causing the noise does not have an
obstruction (cable, cable label, etc).
b. Replace the power supply.
3. If the noise can not be associated with a single power supply, it might be
coming from the cooling fans.
