The BX900 S1 system unit has 18 slots on the front in two rows for
server blades. Slots 2, 17, 7, 10, 18 and 15 can alternatively be fitted with
SX910 S1 and SX940 S1 storage blades. For the fitting rules of the SX960 S1
storage blade and the SX980 S1 storage blade, please refer to the relevant
operating manuals.
To achieve optimum cooling of the system unit, observe the following sequence
when filling the server blade slots:1 - 2 - 3 - 4 - 17 - 9 -10 - 11 - 12 - 18 - 5 - 6 -
7 - 8 - 13 - 14 - 15 - 16. All empty server blade slots must be fitted with dummy
modules.
I
The maximum number of installable server blades depends on the
number of power supply units and fan modules fitted in the system unit,
the available mains voltage and the redundant power supply
requirements, see
"Fitting rules for power supply units and fan modules"
on page 128 .
Different models and configurations of server blades can be combined in the
system unit.

CAUTION!
●
Make sure you observe the safety notes and the information on
handling electrostatic-sensitive devices in the section
"Modules with
Electrostatic-Sensitive Devices" on page 34 .
●
Beware of the energy hazard at the midplane contacts. A short circuit
on these contacts may damage the system.
●
The server blade boots automatically after installation in the
system unit.
When you install a server blade in an active system unit, the server
blade automatically performs a Power-On Self-Test (POST) and then
switches itself off.
If the system unit is switched off when you install the server blade, the
automatic POST is performed immediately after you switch on the
system unit.
●
Any unused server blade slots must be fitted with dummy modules to
comply with electromagnetic compatibility (EMC) regulations and to
ensure sufficient cooling of the system components.
