Thermal Protection
The SDR for each temperature sensor defines three thresholds for temperature
exceeding typical values:
When the value read from the temperature sensor exceeds the upper non-recoverable
threshold, the BMC is responsible for immediately powering a board off without waiting
for instructions from the ShMC.
General Status LEDs
IXB2850 boards provides four general status LEDs on the board front panel. The BMC
controls each individual LED on a front panel.
The general status LEDs on the board front panel are connected to BMC via a local
CPLD.
The BLUE LED is used for hot swap purposes and its function is described in
4.4, “Hot Swap” on page
The other general status LEDs have the following meaning:
The BMC Agent allows the BMC and ShMC to control application specific LEDs. The BMC
Agent receives IPMI messages and uses the baseboard driver API to turn application
LEDs on and off. Customer applications can also use the baseboard driver API to control
these LEDs.
Multi-Color LEDs
The general status LEDs, with the exception of the blue LED, are multi-color (RGB
LEDs). The BMC can switch each LED on/off and set the color based on standard IPMI
requests received from the ShMC. All colors defined in the description of the Get LED
Color Capabilities (NetFn=2Ch/2Dh, CMD=06h) are supported. The general status
LEDs factory default colors are as follows:
Application-Specific LEDs
The BMC on IXB2850 boards does not have the ability to directly control the
application-specific LEDs on an extension card (for example, the Quad Gigabit Ethernet
Mezzanine Card). It can control these LEDs indirectly via the BMC Agent running on the
NPU. To force all application-specific LEDs on or off during the lamp test operation, the
BMC must send an IPMI command to BMC Agent, which is responsible for LED control.
