and set it aside.
Completing the installation
After you connect the cables to the modules and route the cables (if necessary, see
the Rack Installation Instructions for information about routing the cables), connect
power to the BladeCenter unit (if it is not already connected) and verify that it is
working correctly, as follows:
1. Supply power to the BladeCenter unit by connecting the power-module power
cords to a 220-volt power source (a 220-volt PDU that is connected to a
220-volt ac power outlet).
2. Make sure that the LEDs on the module indicate that it is operating correctly:
v The dc power LED and the ac power LED on each power module are lit and
the power-error LED is not lit.
v The OK LED on the management module is lit.
v The OK LED on each I/O module is lit.
3. Make sure that the power-on LED on each blade server is lit, either steady or
flashing.
