CAUTION: If you do not install a module or a power supply in a slot, you must keep the slot filler
panel in place. If you run the chassis with an uncovered slot, the system will overheat.
CAUTION: Static electricity can damage the chassis and other electronic devices. To avoid
damage, keep static-sensitive devices in their static-protective packages until you are ready to
install them.
CAUTION: Before plugging a cable into any port, be sure to discharge the voltage stored on the
cable by touching the electrical contacts to ground surface.
CAUTION: To avoid damaging blade and chassis, do not push the blade into a slot or pull the blade
from a slot using the ejector handles.
