Color State System Status Description
Amber Solid on Fatal Fatal alarm – system has failed or shutdown:
BIOS Detected
1. DIMM failure when there is one DIMM present and no good
memory is .present
1
.
2. Run-time memory uncorrectable error in a non-redundant mode
1
.
3. CPU configuration error (for instance, processor stepping
mismatch).
Integrated BMC Detected
1. CPU IERR signal asserted.
2. CPU 1 is missing.
3. CPU THERMTRIP.
4. No power good – power fault.
5. Power Unit Redundancy sensor – Insufficient resources offset
(indicates not enough power supplies present).
Off N/A Not ready AC power off
Note:
1. BIOS detects these conditions and sends a Set Fault Indication command to the Integrated
BMC to provide
the contribution to the system status LED.
2. Support for upper non-critical limit is not provided in the default SDR configuration. However if a user does
enable this threshold in the SDR, then the system status LED should behave as described.
4.4.3 Chassis ID LED
The chassis ID LED provides a visual indication of a system being serviced. The state of the
chassis ID LED is affected as follows:
Toggled by the chassis ID button
Controlled by the Chassis Identify command (IPMI)
Controlled by the Chassis Identify LED command (OEM)
Table 21. Chassis ID LED Indicator States
State LED State
Identify active via button Solid on
Identify active via command ~1 Hz blink
Off Off
There is no precedence or lock-out mechanism for the control sources. When a new request
arrives, all previous requests are terminated. For example, if the chassis ID LED is blinking and
the chassis ID button is pressed, then the chassis ID LED changes to solid on. If the button is
pressed again, with no intervening commands, the chassis ID LED turns off.
4.4.4 Front Panel/Chassis Inputs
The Integrated BMC monitors the front panel switches and other chassis signals. The front
panel input buttons are momentary contact switches that are debounced by the Integrated BMC
processor firmware. The debounce time is 50 ms; the signal must be in a constant low state for
50 ms before it is treated as asserted.
