Column Description
Fan Speed
Thermal subsystem
The fan speed is displayed as a percentage of maximum RPM.
Onboard Administrator monitors up to 10 fans in the enclosure and adjusts fan speeds as necessary, based
on thermal and power measurements. The speed of individual fans can be adjusted to reduce noise and
power consumption, and to compensate for airflow differences within the enclosure. The performance of
each fan is monitored, and Onboard Administrator reports any failures or warnings to the system log and HP
SIM (when SNMP is enabled).
Monitoring fan zones is only available on the c7000 Enclosure. All other thermal subsystem features and
functions are the same for c3000 and c7000 Enclosures, except where noted.
The following screen shows the Fan Summary page for a c7000 Enclosure.
