Verifying need for replacement

Verify that replacement of the chassis is necessary. Ensure that the components are firmly seated when

troubleshooting, and contact your support provider with any 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 (CR4S-8), or WWN card) do not function properly even after the component was replaced.

•

The psShow or fanShow commands continue to show a faulty component even though the component was

replaced.

•

The slotShow command continues to show a faulty control processor (CP8), core switch (CR4S-8), or port blade

even though the blade was replaced.
