Deactivating a system attention LED or logical partition LED using the Advanced
System Management Interface
You can deactivate a system attention LED or a logical partition LED using the Advanced System
Management Interface (ASMI).
The system attention indicator provides a visual signal that the system as a whole requires attention or
service. Each system has a single system attention indicator. When an event occurs that either needs your
intervention or that of service and support, the system attention indicator lights continuously. The system
attention indicator is turned on when an entry is made in the service processor error log. The error entry
is transmitted to the system error log and the operating system error log.
To perform this operation, your authority level must be one of the following levels:
v Administrator
v Authorized service provider
To turn off the system attention indicator, do the following steps:
1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
2. In the navigation area, expand System Configuration → Service Indicators → System Attention
Indicator.
3. In the right pane, click Turn off system attention indicator. If the attempt is unsuccessful, an error
message is displayed.
