Time and items required
The chassis replacement takes approximately 3 to 4 hours.
The following items are required for the chassis replacement:
v Electrostatic discharge (ESD) grounding strap
v ESD grounding pads for protecting all blades and WWN cards
v Serial cable and workstation computer with a terminal emulator application (such as HyperTerminal
for Windows systems or TIP for Solaris systems), required only if serial console session used.
v Pallet jack or hydraulic or assisted lift that raises a minimum of 140 cm (55 in.) and carries a minimum
of 113 kg (250 lbs).
DANGER
If a lift tool is not available, the director chassis must be depopulated completely before
installing it into the rack. Remove the power supplies, fan modules, all of the blades, the cable
management fingers, and the chassis door (if equipped). Install the empty chassis into the rack
following the chassis installation instructions. The weight of the empty chassis is 54 lbs (24.5 kg)
and must be lifted by minimum 2 people. After securing the chassis to the rack, reinstall the
power supplies, fan modules, and the blades and proceed with the installation.
v A surface on which to place the old chassis, such as a second lift or the pallet originally provided with
the old chassis.
v #1 and #2 Phillips screwdriver. Use #1 Phillips screwdriver for removing and installing blades and
FRUs in chassis.
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” instructs you to run the following commands
and record specific output:

configUpload - all
v configupload -vf
v ipAddrShow -sw
v chassisShow
v nsShow
v nsAllShow
v switchShow -qsfp
v fabricShow

Before beginning replacement, you must also properly shut down the device and disconnect from the
fabric and power using procedures under “Disconnecting from network and fabric” on page 197.
