Chassis replacement overview
Before replacing the chassis, you will need to remove all blades and FRUs, except
the WWN cards, from the existing chassis. You will reinstall these in the
replacement chassis. Do not remove components without following procedures in
this section exactly as you will need to save critical device and SAN information
for these components before disconnecting the chassis from the network, fabric,
and power to begin removal procedures. After you reinstall components in the
new chassis, follow exact procedures to reconnect to the network, fabric and
power, and then download firmware if necessary and verify system operation and
configuration.
Note: You will not remove WWN cards from the old chassis as new cards are
shipped in the replacement chassis.
Before beginning these procedures, perform the following tasks:
v Place the replacement chassis in close proximity to the old chassis.
v Provide a surface on which to place the old chassis, such as a second lift or the
pallet originally provided with the chassis.
v Obtain all tools and other materials listed under “Time and items required” on
page 194.
To unpack and transport the new chassis, follow procedures under “Unpacking
and transporting the device” on page 19.
