Symptom Response
Shelf Manager module boots up in
debug mode
Error code: Shelf FRU Invalid
• Check for the following text after the DEBUG mode login banner:
***Booterrorlogged:***
/sbin/fruinfofailedtoretrievevalidinformationfromshelfmanager
This indicates that the Shelf Manager could not locate valid shelf FRU information. Proceed with the steps
below. If the above text does not appear, see the Software Guide for help with other conditions that can
cause the module to be in debug mode.
• Verify that the Shelf Manager module is installed in a Radisys shelf. The module goes into debug mode if its
Shelf Manager attempts to start up in a non-Radisys shelf. See Disabling the Shelf Manager on page 37 for
instructions on disabling the Shelf Manager.
• When the shelf has redundant SCMs, check whether both SCMs are in debug mode by logging on to the
other SCM. If both are in debug mode, there is a problem with the shelf FRU information (see the next
item). If only one is in debug mode, see page 127.
• Check the Shelf Manager log file (/tmp/shmgr/shmgr.log or the first two backup files) to determine if:
• The shelf FRU information is corrupted. Search for a message that starts with, “(Error) SHMS<FRU
Data>:”. If found, see Restoring shelf FRU information on page 132 to resolve the issue.
• The shelf FRU device is not accessible. Search for one of these messages, “Could not determine FRU
size returning 0” or “Did not find a valid address”. If found, see the next item to resolve it.
• If the shelf FRU device is not accessible, the proxy FRU for accessing the shelf FRU device may not be
present or properly installed. Use these steps:
• Verify that one or more proxy FRUs are present (not applicable for ATCA-6002). The proxy FRUs for
each shelf are:
ATCA-6000: The SPMs located in the rear slots behind the SCMs
ATCA-6006: The PEMs located at the rear of the shelf
ATCA-6014 and ATCA-6016: The RCMs located in the front horizontal slots at the bottom
• Remove and re-insert the proxy FRUs (one at a time) and ensure they are seated properly.

• Reboot the chassis and verify that the problem still exists.
• Remove and re-insert the modules and ensure they are seated properly.
