CAUTION: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized
in your product documentation, or as directed by the online or telephone
service and support team. Damage due to servicing that is not authorized
by Dell is not covered by your warranty. Read and follow the safety
instructions that came with the product.
CAUTION: It is
recommended that you turn off the host server before turning off the
enclosure to prevent loss of data.
Locate the faulty power supply and determine the status
of the LEDs.
If the AC power LED is not lit, check the power cord and power
source into which the power supply module is plugged.
Connect another device to the power source to verify if it is
working.
Connect the cable to a different power source.
Replace the power cable. If the problem is not resolved, see
Getting Help.
If the DC power LED is not lit, verify that the power switch is
turned on. If the power switch is turned on, see step 2.
If the power supply module’s fault indicator is lit, see
Getting Help.
CAUTION: Power supply modules are hot-swappable. The enclosure can operate
on a single power supply module; however both modules must be installed
to ensure proper cooling. A single power supply module can be removed
from a powered-on enclosure for a maximum period of five minutes.
Beyond that time, the enclosure may automatically shut down to prevent
damage.
Reseat the power supply module by removing and reinstalling
it.
NOTE: After installing
a power supply module, allow several seconds for the enclosure to
recognize the power supply module and to determine if it is working
properly.
