12.2.1 Replacing a Power Supply Unit
If a power unit fails, the front orange ID LED blinks in the system unit operator
panel. The defective power unit can be replaced while the basic unit is still
running.

CAUTION
Do not, under any circumstances, remove a fan module if a power
supply unit fails!
The 2100 W power supply unit is not downwardly compatible. It may only
be used in the S2 variant of the PRIMERGY BX600 basic unit.
If a system fault occurs and the front ID LED/fault LED blinks, the fault
must be remedied before additional components can be removed or
added.
To ensure continuous air circulation through the chassis, the slots for the
power supply units must not be left empty and/or open for more than five
minutes when the system is running. Components may be damaged if
this five minute limit is exceeded.
Ê
Check the FAN LED of the power supply units on the back of the system (see
figure 76 on page 132
) to determine which power supply unit is defective.
Ê
First disconnect the power supply cable of the defective PSU from the
mains.
Ê
Remove the power supply cable from the insulated socket of the defective
PSU.
V
CAUTION!
Be careful! The PSU can be very hot!
