Customer replacement responsibilities
Customer responsibilities for replacing a chassis.
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:
1. "Chassis fault indicators"
2. "Preparing for replacement" on page 194
3. "Recording critical device and SAN information" on page 194
4. "Disconnecting from network and fabric" on page 197
Note: The device must be removed from the fabric and powered off to perform these tasks. Contact your
support provider if you have any questions about whether the chassis requires replacement.
Once you have completed these procedures, the IBM SSR can proceed with the physical replacement of
the chassis and components, and labeling procedures. Once the SSR has completed their tasks for
replacing the chassis, you will complete the replacement process by performing the following tasks:
1. "Downloading the configuration" on page 198
2. "Verifying correct operation of system" on page 199
3. "Verifying correct configuration of the fabric" on page 200
Note: The device must be removed from the fabric and powered off to perform these tasks. Contact your
support provider if you have any questions about whether the chassis requires replacement.
Chassis fault indicators
Verify that 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:
v
Visible mechanical damage to the chassis, including damage to sheet metal or card guides that
prevents correct installation of a blade.
v
Bent or damaged connectors on the backplane (the surface inside the chassis to which the blades
connect).
v
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 was
replaced.
v
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.
v
The psShow or fanShow commands continue to show a faulty component even though the component
was replaced.
v
The slotShow command continues to show a faulty control processor, core switch, or port blade even
though the blade was replaced.
