Intel® Server Board S2600WF Product Family Technical Product Specification
87
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.
Table 39 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 onboard NIC. When a network link is
detected, the LED lights up constantly. The LED begins to blink once network activity occurs at a rate that is
consistent with the amount of network activity that is occurring.
7.2.1.6
Storage Device Activity LED Support
The storage device activity LED on the front panel indicates drive activity from the onboard storage
controllers. The server board also provides a 2-pin header, labeled “HDD_Activity” on the server board,
giving access to this LED for add-in controllers.
7.2.1.7
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 show the same state. The system status LED states are driven by the onboard platform
management subsystem.
