Check the following:
• Remove all add-in cards and retry booting with just the on-board components. If successful,
try adding the add-in boards one at a time with a reboot in between to try and pinpoint a
suspect card.
• Remove and reseat memory modules. Try using memory from a known working system.
• Remove and reseat processor and terminator card.
• If you are using a switch box to share a monitor between multiple servers, ensure you are
switched to the proper server.
