Troubleshooting
Temperature Problems
Temperature problems are generally caused by incorrect room temperature, poor air circu-
lation inside the ETERNUS CS800 rack or components, or a malfunctioning cooling fan.
Use the following procedure if a temperature problem is reported:
1. Check the ambient temperature of the room containing the ETERNUS CS800 system
to verify that the temperature falls within the specified range.
2. Inspect for adequate air circulation inside the rack. Some racks may provide additional
fans to improve air circulations. Check the fan for proper operation. Clean or replace
any air filter as necessary.
3. If a component reports a temperature problem, verify that the associated fan is
operating correctly. If necessary, contact Fujitsu customer support to replace the fan
