CAUTION:The
power supply units (PSUs) are hot swappable. Remove and replace only
one PSU at a time in a system that is turned on. Leave a failed PSU
installed in the enclosure until you are ready to replace it. Operating
the system with a PSU removed for extended periods of time can cause
the system to overheat.
NOTE:Ensure that all PSUs
are of the same rated output capacity, generation, and input voltage.
NOTE:The VRTX chassis supports only PSUs with a rated output capacity
of 1100 W or 1600 W.
Steps
Locate the faulty PSU and check the indicators.
The PSU’s AC indicator is green if AC power is available. The PSU’s
fault indicator is amber if the PSU is faulty. If no indicators are
lit, ensure that AC power is available from the PDU or electrical
outlet, and that the power cable is properly connected to the PSU.
Reseat the PSU by removing and reinstalling
it.
NOTE:After installing a PSU, allow several seconds for the system to recognize
the PSUs and determine whether it is working properly.
If the problem is not resolved, swap or replace
the PSU with a known good PSU.
If none of the PSUs show a fault LED and the
server modules do not turn on, check the LCD display or CMC for status
messages. For more information, see the Dell Chassis Management
Controller for Dell PowerEdge VRTX User’s Guide at Dell.com/esmmanuals.
