96 Using the CMC Web Interface
Viewing the Health Status of IOMs
The I/O Modules Status page provides overviews of all IOMs associated with
the chassis. For instructions on viewing IOM health through the Web
interface or RACADM, see "Monitoring IOM Health" on page 254.
Viewing the Health Status of the Fans
NOTE: During updates of CMC or iDRAC firmware on a server, some or all of the fan
units in the chassis will spin at 100%. This is normal.
The Fans Status page provides the status and speed measurements (in
revolutions per minute, or RPM) of the fans in the chassis. There can be one
or more fans.
The CMC, which controls fan speeds, automatically increases or decreases
fan speeds based on system wide events. T
he CMC generates an alert and
increases the fan speeds
when the following events occur:
• The CMC ambient temperature threshold is exceeded.
• A fan fails.
• A fan is removed from the chassis.
To view the health status of the fan units:
1
Log in to the CMC Web interface.
2 Select Fans in the system tree. The Fans Status page displays.
Table 5-4 provides descriptions of the information provided on the Fans
Status page.
