Developing a general understanding of power and thermal
(temperature) issues can help to quickly diagnose problems.
Troubleshooting power issues
Properly configured BladeCenter chassis
provide power redundancy by supplying power to each chassis component
from two or more power modules. BladeCenter chassis
are connected to either AC current or DC current.
Troubleshooting blade server processors throttling
Most current blade servers support the ability to reduce
the power consumption of their processors when needed (throttling).
The advanced management module does not throttle blade servers. The
advanced management module can provide a policy setting to blade server
service processors to reduce power consumption, reduce
heat output, or reduce acoustic noise.
Troubleshooting thermal issues
The advanced management module provides status and alerts
for temperature sensors throughout the chassis. Some sensors provide
an actual temperature and others provide only a notification of whether
a threshold has been exceeded. The advanced management module adjusts
the speed of cooling devices (blowers and fans) based on the environmental
conditions and threshold indications.
