Chapter 8. Chassis replacement
The SAN64B-6 chassis is highly reliable and unlikely to fail. However, the chassis is available as a FRU
and can be replaced using the following basic tasks. Since chassis replacement is a collaborative process
between customers and SSRs please review the information provided in “Customer replacement
responsibilities” on page 69 and “IBM service replacement responsibilities” on page 77 to gain an
understanding of your specific responsibilities for this procedure.

Customer replacement responsibilities
Chassis replacement is a combined effort between the customer and the IBM System Services
Representative (SSR). Before the IBM SSR can perform the physical replacement and labeling
procedures, you must prepare your environment for chassis replacement by performing the following
tasks:
• “Determining the need to replace the chassis” on page 69
• “Preparing for replacement” on page 70
• “Recording critical device and SAN information” on page 71
• “Powering down the switch” on page 74
• “Disconnecting the cables” on page 77
• “Reconnecting system to the network and fabric” on page 74
• “Downloading the configuration” on page 74
• “Verifying correct operation of system” on page 75
• “Verifying correct configuration of the fabric” on page 76
Determining the need to replace the chassis
Before replacing the chassis, verify that the replacement is necessary. Ensure that the components are
firmly seated when troubleshooting. Contact IBM support if you have any questions about whether the
chassis should be replaced. Any of the following events might indicate that the chassis requires
replacement:
• One or more components do not function properly.
• The
psShow or fanShow commands continue to show a faulty component even though the component
has been replaced.
