8.4.7 Identifying Fans
You can view the status of SES components, including the pair of fans located in
each fan and power supply module. A fan is identified in the SES Device menus as a
cooling element.
Perform the following steps to view the status of each fan:
1. Choose “view and edit Peripheral devices → View Peripheral Device Status → SES
Device → Cooling element.”
2. Select one of the elements (element 0, 1, 2, or 3).
Normal fan speeds are indicated by numbers 1 through 7, indicating speeds in the
normal range of 4000 to 6000 RPM. The number 0 indicates that the fan has stopped.
If a fan fails and the Status field does not display the OK value, you must replace the
fan and power supply module.
Cooling elements in the status table can be identified for replacement as shown in
TABLE 8-7.
