Replacing a power supply
The design of the VIPRION platform is such that you can remove a power
supply from the chassis without powering down the system, provided that
there are still enough power supplies to equal one less than the number of
running blades. For example, if the chassis has three blades, you can replace
a power supply, as long as the platform has at least two power supplies
operating during the replacement process.
Important
If the chassis has only one blade operating, at least one power supply must
be installed and operating. In this situation, you must add the power supply
to another power supply bay and then remove the old power supply.
To replace a power supply
1. Using the indentations on either side of the LCD component, pull
the LCD component off the platform.
With the LCD component removed, you can see the power supplies
and the available power supply bays.
2. Unscrew the fastener located in the middle of the power supply eject
lever.
3. Lift the eject lever and slide the power supply out of the power
supply bay.
4. Slide the new power supply into the appropriate power supply bay.
5. Lower the power supply eject lever to fully seat the power supply in
its bay.
6. Secure the power supply in its bay using the fastener attached to the
middle of the power supply eject lever.
7. Replace the LCD component.
