This article provides the way how to check Status LED on Purley (Buchanan Pass) via IPMI tool
LED (light-emitting diode) status description under IPMI (Intelligent Platform Management Interface)
0x30 - General Application commands
0xB0 - Get LED Status
Response:
Byte 1 – Completion Code
Byte 2 – LED status:
[1:0] – Reserved
[3:2] – Status (Amber)
[5:4] – Status (Green)
[7:6] – System Identify
LED Status Definitions:
00b = Off
01b = Blink
10b = On
11b = Invalid (not installed)
For example you get response 20 in hex which means 0010 0000 in binary.
First part is related to Green Status and the second part is related to Amber LED status.
In this case we can see that Green status is active and Amber status is Off.
10 in 0010 means that LED is Solid on, therefore in this case LED is Solid Green.
Another example – you get 04 in response which means 0000 01000.
As you can see only Amber status is active.
01 in 0100 means that LED is blinking, therefore in this case LED is Blinking Amber.

Intel® Server's Integrated Baseboard Management Controller (Integrated BMC) can be accessed by standard, off-the-shelf terminal, open-sourced, or terminal emulator utilities. One example is the IPMIUtility that allows access to sensor status information and power control. Customers own the risk of using open-source utilities. Intel has no control on these utilities and cannot guarantee any fix with these utilities. |
