Subsystem and device status values
The Health Summary page uses the following status values:
• Redundant—There is a backup component for the device or subsystem.
• OK—The device or subsystem is working correctly.
• Not Redundant—There is no backup component for the device or subsystem.
• Not Available—The component is not available or not installed.
• Degraded—The device or subsystem is operating at a reduced capacity.
Previous versions of iLO used a status of Mismatched to indicate the presence of
mismatched power supplies. iLO 4 displays the power supply status as Degraded when
mismatched power supplies are installed.
If you power on a server with nonredundant fans or power supplies, the system health status
is listed as OK. However, if a redundant fan or power supply fails while the system is powered
on, the system health status is listed as Degraded until you replace the fan or power supply.
• Failed Redundant—The device or subsystem is in a nonoperational state.
• Failed—One or more components of the device or subsystem are nonoperational.
• Other—For more information, navigate to the System Information page of the component
that is reporting this status.
• Link Down—The network link is down.
• Unknown—The iLO firmware has not received data about the device status.
If iLO was reset when the server was powered off, some subsystems display the status
Unknown because the status cannot be updated when the server is powered off.
• Not Installed—The subsystem or device is not installed.
Viewing fan information
1. Navigate to the Information→System Information page, and then click the Fans tab.
2. Optional: On servers that support fan redundancy, empty fan bays are hidden. To view the
empty fan bays, click show empty bays. When empty fan bays are displayed, click hide
empty bays to hide them.
The information displayed on the Fan Information page varies depending on the server
configuration.
If the server is powered off, the system health information on this page is current as of the last
power off. Health information is updated only when the server is powered on and POST is
complete.
