network management device connected to the network interface connector port is not properly operating, go to step 8.
4. Ensure that the serial cable is a null modem cable.
5. Reseat the serial cable to the serial connector on the DRAC/MC module and to the serial device.
6. Connect a known-working null-modem serial cable between the DRAC/MC module and the serial device.
NOTE: After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is
working properly. The power supply DC power indicator turns green if the power supply is functioning properly. See Figure2-6.
NOTICE: The fan modules are hot-pluggable. Remove and replace only one fan module at a time in a system that is turned on. Operating the system
with a fan module removed for extended periods of time can cause the system to overheat.
