V CAUTION!
Follow the safety instructions in the chapter "Important information" on
page 25.
In the PRIMERGY TX300 S5 server, the following components are considered
to be CSS components:
– Hot-plug components
– Hot-plug power supply units
– Hot-plug hard disk drives
– Hot-plug fan modules (redundant and standard fan modules)
You can expand or replace the hot-plug components during operation.
– Non-hot-plug components
– Memory modules
– Expansion cards
These components can be changed by you in the event of an error. To do so,
first switch off the server and disconnect it from the network before
proceeding.
Expansions and upgrades may only be carried out by authorized specialist
personnel. These operations are described in the "Options Guide".
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 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.
