Troubleshooting System Cooling

Problem

l

Systems management software issues a fan-related error message

l

Front-panel status LCD indicating a problem with cooling

Action

Cooling of the entire system or individual components inside the system can be affected by the following conditions:

l

Ambient temperature surrounding the system is too high

l

Airflow intake and output for the system is obstructed

l

Cables inside the system obstruct cooling fan intake or output

l

Expansion-card filler brackets are not installed over empty expansion slots

l

An individual cooling fan has failed (see "

Troubleshooting a Cooling Fan

")

To maintain proper cooling while the system is on, ensure that none of the conditions listed above exists. If an individual cooling fan has failed, see
"

" to resolve the problem.

NOTE:

Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the

System Setup program, the problem may be caused by software rather than by a defective battery.

NOTE:

If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation

is caused by a defective battery.

NOTICE:

The power supplies are hot-pluggable. The system requires one power supply to be installed for the system to operate normally. The system

is in the redundant mode when two power supplies are installed. Remove and replace only one power supply at a time in a system that is powered on.

NOTE:

After installing a new power supply, allow several seconds for the system to recognize the power supply and determine whether it is

working properly. The power-on indicator will turn green to signify that the power supply is functioning properly (see

Figure 2

-4

).
