Safety notes
CAUTION
▶
Devices and components inside the server remain hot after
shutdown. After shutting down the server, wait for hot components
to cool down before installing or removing internal options.
▶
Circuit boards and soldered parts of internal options are exposed
and can be damaged by static electricity. Always discharge static
build-up (e.g. by touching a grounded object) before handling
electrostatic-sensitive devices (ESDs).
▶
Do not touch the circuitry on boards or soldered parts. Hold circuit
boards by their metallic areas or edges.

Basic information
This section provides instructions for the system board and the following
components:
● CMOS battery (CR2450)
The real-time clock is powered by a lithium coin cell (CMOS battery) when
mains get lost. This cell lasts up to five years, depending on ambient
temperature and use.
If the CMOS battery is depleted or falls below minimum voltage levels, it
need to be replaced immediately.
● TPM (Trusted Platform Module)
The system board is optionally equipped with a TPM. This module enables
programs from third party manufacturers to store key information, for
example drive encryption using Windows Bitlocker Drive Encryption.
