2. Reduce the server to the minimum power-on configuration. The minimum hardware an rp54xx series
system requires for power on is:
• Platform monitor
• Power converter
• System board
• PCI I/O backplane
• Display board
• Any single power supply (power supply 0 preferred)
• Any 7 fans (it is probably not necessary to remove a fan—however if fewer than 7 fans are installed
and functional, the system will not remain powered up).
a. Replace these FRUs individually or all at once to get the system to power up.
b. Add remaining FRUs until system is complete.
NOTE When adding processors, be sure to install the processor support modules first. If
processors are installed but the corresponding processor support module is not
installed, the system will not power up. A system alert that describes a faulty processor
support module 0 or 1 is generated.
System Will Power On but Will Not Enter Self-Test
In this situation, all the DC voltages needed to operate the system are available but the system appears dead.
In this case, there will be very little useful information available from any LEDs or other physical indicators
on the system. It will be necessary to utilize the GSP to troubleshoot. Thus, it is imperative that the GSP is
functional and that there is access to the GSP commands and output through any of the available interfaces
(e.g. GSP LAN, console port, etc.).
