Verifying the need for replacing the chassis
To verify that it is necessary to replace the chassis, make sure that the components are firmly seated,
troubleshoot the chassis, following the list below, and contact your support provider with any remaining
questions about whether the chassis should be replaced.
Any of the following events might indicate the need to replace the chassis:
•
Visible mechanical damage to the chassis, including damage to sheet metal or card guides that
prevents correct installation of a blade.
•
Bent or damaged connectors on the backplane (the surface inside the chassis to which the blades
connect).
•
One or more components (such as a power supply, blower assembly, port blade, control processor
blade (CP8), core switch blade (CR8), or WWN card) do not function properly even after the
component is replaced.
•
The psShow or fanShow commands continue to show a faulty component even though the com-
ponent has been replaced.
•
The slotShow command continues to show a faulty control processor (CP8), core switch (CR8),
or port blade even though the blade has been replaced.
