NMI Button Support
When the NMI button is pressed, it puts the server in a halt state and causes the BMC to issue a non-maskable
interrupt (NMI). This can be useful when performing diagnostics for a given issue where a memory download
is necessary to help determine the cause of the problem. Once an NMI has been generated by the BMC, the
BMC does not generate another NMI until the system has been reset or powered down.
•
The following actions cause the BMC to generate an NMI pulse:
•
Receiving a Chassis Control command to pulse the diagnostic interrupt. This command does not cause an
event to be logged in the SEL.
Watchdog timer pre-timeout expiration with NMI/diagnostic interrupt pre-timeout action enabled.
The following table describes behavior regarding NMI signal generation and event logging by the BMC.

NIC Activity LED Support
The Front Control Panel includes an activity LED indicator for each on-board Network Interface Controller
(NIC). When a network link is detected, the LED will turn on solid. The LED will blink once network activity
occurs at a rate that is consistent with the amount of network activity that is occurring.
8.4.6
Hard Drive Activity LED Support
The drive activity LED on the front panel indicates drive activity from the on-board hard disk controllers. The
server board also provides a header giving access to this LED for add-in controllers.
8.4.7
System Status LED Support
The System Status LED is a bi-color (Green/Amber) indicator that shows the current health of the server
system. The system provides two locations for this feature; one is located on the Front Control Panel, the other
is located on the back edge of the server board, viewable from the back of the system. Both LEDs are tied
together and will show the same state. The System Status LED states are driven by the on-board platform
management sub-system.
