Reinstall the left and right end caps to the front of the enclosure.
Removing and replacing parts
If three persons or a lift are not available to install the control enclosure, the weight of the control enclosure must be reduced before it can
be safely lifted. Follow the procedures to remove several parts of the control enclosure. Reinstall the parts after the control enclosure is
installed in the rack. If you did not remove any parts, continue to
on page 6.
Removing and replacing a power supply unit
You can remove and replace either of the two hot-swap redundant power supply units (PSUs) in a FlashSystem 7200 control enclosure.
These redundant power supplies operate in parallel, one continuing to power the enclosure if the other fails.
About this task
• You must follow recommended procedures for handling electrostatic discharge (ESD)-sensitive devices.
• No tools are required to complete this task. Do not remove or loosen any screws.
• Do not insert a PSU if the PSU slot does not contain a power interposer.
Procedure
1.
Fold out the handle so that it extends perpendicular to the PSU (cable retention clip (1), LED indicator (2), PSU release tab (3), PSU
handle (4), and the power interposer release tab (5).
2.
Hold the PSU handle and press the PSU release tab. Steadily pull the handle horizontally to slide the PSU from the enclosure. Support
the PSU with your other hand as it is released.
3.
To replace the PSU, fold out the handle so that it extends perpendicular to the PSU.
4.
Keep the PSU handle extended and support the PSU. Slide the power supply into the enclosure until the release tab engages with a
"click".
