10.2.3 Replacing Defective Parts
All rear panel IO cards are hot-pluggable which means that they can be exchanged during uptime. This allows
fast replacement of a card in the case of a hardware failure. Providing the card is of the same type and fitted to
the same rear panel slot as the faulty card, the new card will immediately take over the same functions.
Other components can be serviced by removing the top cover of the Power Core frame. You must disconnect
the unit from its power source to perform these operations.
Do
NOT
remove the cover while the device is powered.
