Multifunction I/O Board (MFIOB) Test Fails
Multifunction I/O Board (MFIOB) Test Fails
The multifunction I/O board (MFIOB) test checks the MFIOB. If the MFIOB test finishes 
successfully, the service processor (SP) extinguishes the amber service LED on the 
PMF CRU or IOMF CRU and generates an event, completing the POST. If the MFIOB 
test fails, the MFIOB is either partially operational or not operational. 
Indications of a Failed MFIOB Test Corrective Action
•
PMF CRU or IOMF CRU amber service 
LED lights if the MFIOB is partially 
operational.
•
PMF CRU or IOMF CRU green power-on 
and amber service LEDs do not light if the 
MFIOB is not operational.
1. Retry the operation. 
2. If the test fails a second time, use the 
OSM or TSM Event Viewer to check 
the event logs for the 
SpEvCruTestComplete event 
message. 
3. Replace the PMF CRU or IOMF CRU.
