8 CSS components
This chapter describes how to handle CSS components and how to identify
defective CSS components and replace them yourself.
I Further information on the CSS concept is provided in the “Customer Self
Service (CSS)” manual on the ServerBooks DVD.
Upgrades, updates and replacement of non-CSS components are
described in the “Options Guide” or in the service supplement and may
only be performed by authorized specialist personnel.
V CAUTION!
Follow the safety instructions in the chapter “Important information” on
page 25.
8.1 Hot-plug components
This section describes how to handle the hot-plug components and/or how to
modify your server hardware (e.g. adding/replacing hot-plug power supply units
or hot-plug HDD modules).
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
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 without interrupting operation.
