Chassis replacement overview
Use the following information to help prepare for a chassis replacement. 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.
Before beginning these procedures, perform the following tasks:
• Place the replacement chassis in close proximity to the old chassis.
• Provide a surface on which to place the old chassis, such as a second lift or the pallet originally provided
with the chassis.
• Obtain all tools and other materials listed below.
Attention: Refer to “Safety notices and labels” on page xiii and “ESD precautions” on page xvi
before performing any removal or installation procedures.
Time and items required
The chassis replacement procedure takes approximately 1 hour to complete, depending on number of
SFPs and cables installed.
The following items are required for the chassis replacement procedure:
• Replacement chassis
• ESD grounding strap
• Phillips #2 screwdriver
• 1/4 in. straight slot screwdriver
Preparing for replacement
Before beginning replacement procedures you must run the a series of Fabric OS commands and record
device information for safekeeping that may be required for installing and configuring the new chassis.
This includes information on licenses, IP address, WWN, serial numbers, switch ID, location of
configuration files, and fabric details. It also includes information that might be required by Technical
Support. “Recording critical device and SAN information” on page 71 instructs you to run the following
commands and record specific output:
• supportShow
• configUpload - all
• configupload -vf
• ipAddrShow -sw
• chassisShow
• nsShow
• nsAllShow
• switchShow -qsfp
• fabricShow
• licenseShow
• supportShow
Before beginning replacement, you must also properly shut down the device and disconnect from the
fabric and power using procedures under “Powering down the device” on page 44.
