Controller failure in a single-controller configuration
Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write
to CompactFlash process, only the components needed to write the cache to the CompactFlash are
powered by the supercapacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the
cache is copied to CompactFlash, the remaining power left in the supercapacitor is used to refresh the
cache memory. While the cache is being maintained by the supercapacitor, the Cache Status LED flashes
at a rate of 1/10 second on and 9/10 second off.
If the controller has failed or does not start, is the Cache Status LED on/blinking?
Answer
No, the Cache LED status is off, and the
controller does not boot.
No, the Cache Status LED is off, and the
controller boots.
Yes, at a strobe 1:10 rate - 1 Hz, and the
controller does not boot.

Troubleshooting
Actions
No action required.
Verify that the power cord is properly connected, and check
the power source to which it connects.
Check that the power supply CRU is firmly locked into
position.
Check the event log for specific information regarding the

fault, and contact Lenovo for assistance.
Actions

fans in both modules receive power through a common bus on
the midplane, so if a power supply unit fails, the fans continue
to operate normally.

position.
Verify that the power cable is connected to a power source.
Verify that the power cable is connected to the enclosure's
power supply unit.
