You can remove and replace either of the hot-swap redundant power supply units (PSUs) in a FlashSystem 7300 control enclosure. These
redundant power supplies operate in parallel, .
About this task
Notes:
Do not insert a PSU if the PSU slot does not contain a power interposer.
Do not operate the enclosure without a power interposer and PSU in a PSU slot for longer
than 5 minutes. Operating for longer than this period might cause the enclosure to shut
down due to overheating.
Remove the replacement PSU from its packaging and have it available before carrying out
this procedure.
No tools are required to complete this task. Do not remove or loosen any screws.
Although many components are hot-swappable, they are intended to be used only when your
system is not active (no I/O operations). If your system is powered on and processing I/O
operations, go to the management GUI and follow the fix procedures. Initiating the replacement
actions without the assistance of the fix procedures can result in loss of data or loss of
access to data.
Be careful when you are replacing the hardware components that are located in the back of
the system. Do not inadvertently disturb or remove any cables that you are not instructed to
remove.
When you replace this part, you must follow recommended procedures for handling
electrostatic discharge (ESD)-sensitive devices.
Procedure
Identify the location of the control enclosure that requires service. The Event Log contains
the enclosure MTM and serial number.
This figure shows the location of the Power Supply Unit 1
1 and Power Supply Unit 2 2 .
Identify the PSU that requires service; the Event Log contains the ID of the PSU
that failed.
Removing the PSU
Release the cable retention clip and disconnect the power cord from
the power supply unit that you are replacing.
Fold out the handle so that it extends perpendicular to the PSU.
Holding the PSU handle, press and hold the PSU release tab and steadily pull the handle
horizontally to slide the PSU from the enclosure, as shown in this figure.
Support the PSU with your other hand as it is released from the enclosure.
Replacing the PSU
Fold out the handle so that it extends perpendicular to the PSU.
While keeping the PSU handle extended and supporting the PSU slide the
power supply into the enclosure until the release tab engages with a 'click'.
Connect the power cord to the power supply and to a properly grounded
electrical outlet. Secure the cable with the cable retention clip on the rear of the power supply
unit.
Note: After the power cord is connected to the electrical outlet, make sure that the LED
indicator, shown in ,
is lit.
