What if the processor module does not boot?

Several problems can cause a processor module not to boot. Here are some things to look for and possible solutions.

Things to Notice:

  • Ensure that a system controller is installed in slot 1 and working properly.
  • Which LEDs come on? The PWROK/FAULT LED should stay lit green. The Drive LED should blink during boot as the disk is accessed.
  • What has changed about the system? Did you recently move the system? Was there electrical storm activity? Did you recently add a new module, memory chip, or piece of software?
  • Refer to your chassis documentation for additional troubleshooting steps.

Things to Try:

  • Make sure the chassis is plugged in to a working power source.
  • Check any fuses or circuit breakers in the chassis or other power supply (possibly a UPS).
  • Make sure the processor module is firmly seated in the chassis.
  • Remove all other modules (except the system controller) from the chassis.
  • Remove any nonessential cables or devices.
  • Try the processor module in a different chassis.
  • Try a similar processor module in the same chassis.
  • Clear the CMOS.
  • Recover the hard drive on the processor module.
  • Make sure the RAM is properly seated.
