Action
CAUTION:
Only trained service technicians are authorized to remove the enclosure cover and access any of the
components inside the enclosure. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the enclosure and protecting against
electrostatic discharge.
1 Check that at least two physical disks are present in the enclosure. A minimum of two physical disks
must be installed. If they are not, install the minimum number of physical disks. If the problem
persists, go to step 2.
2 Turn off the enclosure and attached peripherals, and disconnect the enclosure from the electrical
outlet.
3 Locate the faulty power supply.
NOTICE:
Power supply/cooling fan modules are hot-pluggable. The enclosure can operate on a single functioning
power supply; however, both modules must be installed to ensure proper cooling. A single power supply/cooling
fan module can be removed from the enclosure for up to 5 minutes, provided the other module is functioning
properly. After 5 minutes, the enclosure will overheat and may cause an automatic thermal shutdown.
4 Ensure that the power supply is properly installed by removing and re-installing it. See
"Removing and Installing the Power Supply/Cooling Fan Module" on page 62.
NOTE:
After installing a power supply, allow several seconds for the enclosure to recognize the power
supply and determine if it is working properly.
5 If the problem is resolved, skip the rest of this procedure.
If the problem persists, remove the faulty power supply. See "Removing and Installing the Power
Supply/Cooling Fan Module" on page 62.
6 Install a new power supply. See "Removing and Installing the Power Supply/Cooling Fan Module" on
