FB-DIMMs
1. Access the ILOM -> prompt.
Refer to the Sun Integrated Lights Out Manager (ILOM) 3.0 Supplement for Sun
SPARC Enterprise T5120 and T5220 Servers for instructions.
2. Use the show faulty command to determine how to clear the fault.
■ If show faulty indicates a POST-detected the fault go to Step 3.
■ If show faulty indicates a host-detected fault (output displays a UUID), go
directly to Step 4.
3. Use the set command to enable the FB-DIMM that was disabled by POST.
In most cases, replacement of a faulty FB-DIMM is detected when the service
processor is power cycled. In those cases, the fault is automatically cleared from
the system. If show faulty still displays the fault, clear it with the set
command.
4. Perform the following steps to verify the repair:
a. Set the virtual keyswitch to diag so that POST will run in Service mode.
b. Power cycle the system.
-> set /SYS/MB/CMP0/BR0/CH0/D0 component_state=Enabled
-> set /SYS/keyswitch_state=Diag
Set ‘keyswitch_state’ to ‘Diag’
-> stop /SYS
