Replacing the DC Director chassis door
The chassis replacement takes approximately 3 hours. The following items are required for the chassis
replacement:
CAUTION:
Wear a grounded ESD strap when handling DC Director components and port blades. The Director
chassis provides a grounding connection above the power connectors. Also,
antistatic packaging.
•
Electrostatic discharge (ESD) grounding strap
•
ESD grounding pads for protecting all blades and WWN cards
•
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 in. (140 cm) and carries a minimum
of 250 lb (1 13 kg)
•
A surface to place the old chassis on, such as a second lift or the pallet originally provided with the old
chassis
•
#2 Phillips screwdriver
Verify need for replacing the chassis
Verify that replacement of the chassis is necessary. Ensure that the components are firmly seated when
troubleshooting, and contact your support provider with any questions about whether the chassis should be
replaced.
Any of the following events might indicate the need to replace the chassis:
•
Visible mechanical damage to the chassis, including damage to sheet metal or card guides that
prevents correct installation of a blade.
•
Bent or damaged connectors on the backplane (the surface inside the chassis to which the blades
connect).
•
One or more components (such as a power supply, blower assembly, port blade, control processor
blade (CP8), core switch blade (CR8), or WWN card) do not function properly even after the
component is replaced.
•
The psShow or fanShow commands continue to show a faulty component even though the component
has been replaced.
