8 Hot-plug components
This chapter describes how to handle the hot-plug components and how to
modify your server hardware (e.g. installing/removing hot-plug power supply
units or hot-plug HDD modules) .
I Upgrades, updates and replacement of non-hot-pluggable components
are described in the “Options Guide” or in the service supplement and
may only be performed by authorized specialist personnel.
The hot-plug procedure increases the availability of system operation and
guarantees a high degree of data integrity and failsafe performance.
V CAUTION!
Follow the safety instructions in the chapter “Important information” on
page 21.
8.1 Hot-plug power supply units
I A redundant power supply can be created by installing a second hot-
pluggable power supply unit (optional). If one power supply unit fails, the
other unit ensures operation can continue. The defective power supply
unit can be replaced online.
