Stopped Intel® Server Chassis SC5600LX power supply fans may cause
continuous reboots
Problem In the Intel
®
Server Chassis SC5600LX based system, if a power supply fan
fails, the system may enter a continuous reboot cycle. If redundant power
supply modules are populated, the system will only reboot if fans in both power
supply modules fail simultaneously.
Implication If a power supply fan fails, the system may enter a reboot cycle. This problem
will only occur in instances where a shutdown is expected. The system will
reboot rather than shutting down. The LED on the power supply module with
fan fails will turn into amber to indicate this failure state.
