Observing LEDs to Isolate the Problem
The CMC has an LED which changes color to indicate:
Table 34. LED color indicators
Color Description
Blue Normal operation
Blue, blinking ID (0.5 second on, 0.5 second off)
Amber Chassis fault summary
Amber, blinking Chassis fault with concurrent ID
Troubleshooting Network Problems
The internal CMC trace log allows you to debug CMC alerts and networking. You can access the trace log using the CMC Web interface
or RACADM. See the gettracelog command section in the RACADM Command Line Reference Guide for iDRAC and CMC.
The trace log tracks the following information:
• DHCP — Traces packets sent to and received from a DHCP server.
• DDNS — Traces dynamic DNS update requests and responses.
• Configuration changes to the network interfaces.
The trace log may also contain CMC firmware-specific error codes that are related to the internal CMC firmware, not the managed
system’s operating system.
General troubleshooting
When a success message is displayed after an operation completion, such as saving a Server Profile, sometimes the action may not take
effect.
To resolve this issue, check if any of the CMC service ports for SSH, Telnet, HTTP, or HTTPS uses ports commonly used by OS services
such as 111. If it is used by CMC service ports, change the settings to a non-reserved port. For more information on reserved ports, see

Troubleshooting storage module in FX2 chassis
The following information helps you to troubleshoot issues related to storage sleds in the FX2 chassis.
• Problem: Storage module is not detected on insertion. Storage module inserted and the associated server powered on, is not
detected
Resolution: . Ensure that the associated server is power cycled after the storage module is inserted.
• Problem: Storage module is inserted and the associated server is power cycled, but the storage module is not detected.
Resolution: Check the chassis log for more details about the failure. Verify if there is any hardware failure such as no detection of
cable spool or RAID.
• Problem: Storage Amber LED blinks.
Resolution: Ensure that the storage module is inserted properly and check the chassis log for warning messages. This error can be
cleared only if the underlying fault is addressed and the associated host is power cycled with the sled removed or through a sled virtual
reseat.
Problem: Storage module RAID firmware update is not effective.
Resolution: When in split-dual host mode, each host that is connected to the storage sled RAID must be power cycled for the RAID
firmware change to be effective.
• Problem: PCIe slot reassignment option is disabled in the GUI.
Resolution: Ensure that all hosts in the chassis are powered on. If you attempt changing this setting from RACADM while a host is
powered on, an error message is displayed. The chassis configuration administrator privilege is required to change this setting.
• Problem: PCIe slot reassignment enabled and host is powered on, but the PCIe slots are not powered on.
Resolution: Check the Chassis Log for warning messages associated with outdated BIOS, iDRAC, or unsupported host.
