A.5
During Operation
Problem
Possible Reason
Solution
Module runs 
unstable, hangs or 
powers down after 
some duration of 
operation.
Disregard of 
environmental 
requirements
Inadequate 
airflow
Check that internal system temperature remains within 
specified ranges for all system devices. Ensure that the 
system configuration you are using is validated for safe 
thermal performance.
Check if the Shelf Manager is receiving thermal events (for 
example processor throttling or thermal trip events, or 
CPU/blade/inlet air temperature exceeding upper non-
recoverable thresholds). 
The module also has an autonomous, built-in protection 
against potentially catastrophic thermal situations. 
Check if the airflow is adequate see 
Module boots BIOS 
but cannot load the 
Operating System.
Boot order is not 
properly 
configured.
Check if the target boot device is properly set up in the 
BIOS configuration. 
BIOS provides options to configure the boot order. For 
instance, the user can configure whether the module 
should load the OS over Ethernet, or SATA. Refer to
The PCI Express 
fabric interface 
does not work. A 
PCI scan does not 
see any device on 
this interface.
The PCI Express 
link has been 
disabled by E-
keying.
Check if the carrier supports a PCI Express link on AMC 
ports 4-11. If not, E-keying will disable the PCI Express 
link.
Check if multiple root-class PCI Express devices are 
present in the system. If present, E-keying will disable all 
PCI Express links except one that it is connected to a 
primary port of the PCI Express switch on the carrier (if the 
carrier has a switched architecture for PCI Express).
