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 17.
