the compute node. In addition, the fault LED on the chassis system LED
panel is lit. You can check the CMM event log to determine the source of
the condition. For more information, see “Viewing event logs without
restarting the compute node” on page 64“Viewing event logs without
restarting the compute node” on page 56. See “Light path diagnostics
LEDs” on page 59 for more information about the LEDs on the compute
node.
The fault LED turns off only after the error is corrected.
Note: When the fault LED turns off, you should also clear the IMM event
log. Use the Setup utility to clear the IMM event log.
Check log LED
When this yellow LED is lit, it indicates that a condition that causes an
event to be logged in the event log has occurred. To view the IMM2 event
log see “IMM event log” on page 63
The check log LED can be turned off through the CMM led command, the
CMM web interface, or IBM Flex System Manager management software
(if installed).
v For more information about the CMM led command, see the "IBM Flex
System Chassis Management Module: Command-Line Interface
Reference Guide" at http://ralfss21.raleigh.ibm.com:8099/help/topic/

v From the CMM web interface, select Compute Nodes from the Chassis
Management menu. For more information, see the "IBM Flex System
Chassis Management Module: User's Guide" athttp://

Notes:
1. Alternatively, you can use the CMM_INDICATES_ITE_ERROR_N
command to light the check log LED. See the "IBM Flex System Chassis
Management Module: Command-Line Interface Reference Guide" at
http://ralfss21.raleigh.ibm.com:8099/help/topic/

2. You can check the CMM event log to determine the source of the
condition. For more information, see “Viewing event logs without
restarting the compute node” on page 64.
Identify LED
The system administrator can remotely light this blue LED to aid in
visually locating the compute node. When this LED is lit, the identify LED
on the IBM Flex System chassis is also lit. The identify LED can be lit and
turned off through the CMM led command, the CMM web interface, or
IBM Flex System Manager management software (if installed).
