ID Button with integrated ID LED – Toggles the integrated ID LED and the Blue server board
ID LED on and off. The ID LED is used to identify the system for maintenance when installed in
a rack of similar server systems. The ID LED can also be toggled on and off remotely using the
IPMI “Chassis Identify” command which will cause the LED to blink for 15 seconds.
NMI Button – When the NMI button is pressed, it puts the server in a halt state and issues 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. To
prevent an inadvertent system halt, the actual NMI button is located behind the Front Control
Panel faceplate where it is only accessible with the use of a small tipped tool like a pin or paper
clip.
Network Activity LEDs (NIC LED) – 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.
System Reset Button – When pressed, this button will reboot and re-initialize the system.
System Status LED – 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.
System Power Button with power LED – Toggles the system power on and off. This button
also functions as a sleep button if enabled by an ACPI compliant operating system. Pressing
this button will send a signal to the iBMC, which will either power on or power off the system.
The integrated LED is a single color (Green) and is capable of supporting different indicator
states as defined in the following table:

HDD Activity LED - 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.
