Event repository
To store messages on events that occur in the system environment, the
ServerView management blade is equipped with an event repository,
providing a 2 x 32 MB SDRAM.
Auto configuration
The management function auto configuration is used to back up system
parameters to a ROM, which is located on the management blade. It also
provides the possibility to restore these parameters if required. This
reduces the risk if system configuration data have been corrupted or lost.
SSL (Secure Socket Layer)
The Manager Blade provides SSL for network data privacy for Telnet as
well as for HTTP connections.
The base configuration of the system unit contains one management blade. For
more information on the management blade, see the manual "PRIMERGY

Interface Description".
Power supply
The system unit has six installation bays for hot-plug power supply units. There
are two types of power supply units available, standard PSU and High
Efficiency PSU (hereinafter referred to as HE PSU), see
"Electrical data
(standard PSU)" on page 31
and
"Electrical data (HE PSU)" on page 31
. Both
types automatically set themselves to a voltage in the range of 100 - 240 V.
The base configuration includes three power supply units. As an option, you can
set up a redundant power supply with three additional power supply units. If a
power supply unit fails, the redundant configuration assures continued
operation. The defective power supply unit can be replaced during operation
(for further details see the "PRIMERGY BX900 S2 System Unit Upgrade and
Maintenance Manual").

by the fan modules. Each of the fan units contains 2x2 fans. The fan modules
have the same aspect ratio as the power supply units. Depending on the
