Replacing the chassis160
Replacing the chassis — items required
The chassis replacement procedure takes approximately 3 hours to complete. Obtain the following
before starting the chassis replacement procedure:
• Electrostatic discharge (ESD) grounding strap
• ESD grounding pads for protecting control processor (CP) cards, port blades, and the WWN
card
• 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.
• Pallet jack or hydraulic or assisted lift that raises a minimum of 55 inches (140 cm) and carries a
minimum of 250 lbs. (113 kg)
• A surface to place the old chassis on, such as a second lift or the pallet originally provided with
the old chassis
• 1/2 inch socket wrench to remove the pallet bolts
• Torque wrench with #2 Phillips screwdriver tip (if switch is installed in a cabinet)
• #2 slotted screwdriver
How to determine whether or not to replace the chassis
If you have not already done so, confirm that you need to replace the chassis before continuing. The
following events might indicate that the chassis is faulty:
• Visible mechanical damage to the chassis, including damage to sheet metal or card guides that
prevents correct installation of a CP card or port blade.
• Bent or damaged connectors on the main backplane (the surface inside the chassis to which CP
cards and port blades connect) or on the blower backplane (the surface to which the blower
assemblies connect).
• One or more 4/256 SAN Director components (such as a power supply, blower assembly, port
blade, CP card, or WWN card) do not function properly even after the component is replaced.
• An AC power switch shuts off automatically even though all power supplies are removed from
the chassis.
• The psShow or fanShow commands continue to show a faulty component even though the
component has been replaced.
• The slotShow command continues to show a faulty CP card or port blade even though the
blade has been replaced.
Record critical switch and SAN information
All commands must be entered from a CLI session (telnet or serial) to the active CP card unless
otherwise indicated. For detailed information about Fabric OS commands, refer to the
Fabric OS
command reference manual
. Use a checklist to ensure that all required information is recorded (see
Table 42 on page 165).
