Locating Faulty CPUs and DIMMs

To Locate Faulty CPU’s and DIMMs
Every CPU module supports the following diagnostic procedure.
1. Make sure that the system is powered down, but that power cables are still
connected to the PSU. This ensures that standby power is flowing to the CPU
modules
2. Locate the CPU module with a lit amber LED visible at its top edge. The LED
indicates that the module has faulty CPU or DIMM.
3. Remove standby power by disconnecting all power cables from the PSU.
Caution – Removing or inserting a CPU module while standby power is available
can damage the module.
4. Remove the CPU module you previously identified from its slot in the CPU
module bay. See “ “To Replace a CPU Module or CPU Filler Board” on page 18 .
5. Press the module’s fault remind button. If a DIMM is faulty, an amber LED is lit
in one of the DIMM’s slot handles. If the CPU is faulty, a CPU fault LED is lit.
These LEDs are powered by an on-board capacity and can remain lit about a
minute.
To identify the fault remind button and the CPU fault LED, refer to the individual
module descriptions in “CPU Module Models” on page F-1.
