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.
Recording critical PowerConnect B-DCX-4S and SAN information
All commands must be entered from a CLI session (Telnet or serial) to the active CP blade unless
otherwise indicated.
