Yellow LED on a BEB Not Lit 
Symptom 
Corrective Action 
1. Yellow LED not lit inside 
BEB enclosure. 
• Make sure that both 
the drive FRU and 
3216 logic board is 
powered on. 
• Check the integrity of 
the fiber-optic cable 
connection: 
1. Inspect the cable 
connectors at the BIC and 
BEB ends. Make sure the 
connectors have not been 
forced in backwards. The 
connector keyway must 
mate with the key in the 
receptacle. 
2. Replace or inspect the 
cable for defects or kinks. 
3. Make sure the cable 
maximum bend radius of 
10 centimeters (4 inches) 
has not been exceeded. 
4. If the yellow LED still does 
not light, call the GCSC.
