Chassis Fault Indicators

Verify that the replacement of the chassis is necessary. If error messages and LED operation indicates faulty components, ensure that the components are firmly seated. 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 the 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, core switch blade, or WWN card) do not function properly even after the component is replaced.
• Intermittent FAULTY codes for blades. Reseat the blade and visually inspect the ejector stiffening rails for possible wear or damage. It is important that the blade ejector handles not slip out during blade installation. If this happens, it is usually due to excessive wear or damage to the ejector stiffening rails.
• 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, core switch, or port blade even though the blade was replaced.
