8.1 Hot-plug components
This section describes how to handle hot-plug components and how to modify
your server hardware (e.g. adding/replacing hot-plug power supply units).
The hot-plug procedure increases the availability of system operation and
guarantees a high degree of data integrity and failsafe performance.
8.1.1 Hot-plug power supply units
The server must have at least two hot-plug power supply units (PSUs) to ensure
redundant power supply. If one power supply unit fails, the other unit ensures
that the operation can continue uninterrupted. The defective power supply unit
can be replaced during operation (hot-plug).
V CAUTION!
● Areas around the power supply unit may remain extremely hot after
shutdown. Wait for a while after shutdown before removing the power
supply unit.
● When installing the power supply unit, be sure to confirm that the
connector of the PSU is not damaged or bent.
● Do not insert your hands in the power supply unit slot when removing
the power supply unit. Doing so may cause electric shock.
● If the power supply unit is hard to remove, do not pull out it by force.
● The power supply unit is heavy, so handle it carefully. If you drop it by
mistake, injuries may result.
