CAUTION:
Ensure that the airflow direction of the power supply unit matches that of the installed
fan tray. The power supplies and fan trays are clearly labeled with either a green arrow
with an "E", or an orange arrow with an "I."
CAUTION:
To protect the serial port from damage, keep the cover on the port when not in use.
CAUTION:
Never leave tools inside the chassis.
CAUTION:
Use the screws specified in the procedure. Using longer screws can damage the device.
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.
CAUTION:
Remove the protective cover on the port side of chassis before applying power. This cover
is attached over the air vents. If not removed, the chassis can overheat and will eventually
shut down.
Electrical cautions
CAUTION:
Use a separate branch circuit for each power cord, which provides redundancy in case one
of the circuits fails.
CAUTION:
For the NEBS-compliant installation of a device with AC or DC systems, use a ground
wire of at least 2 AWG. The ground wire should have an agency-approved crimped
connector (provided with the device) attached to one end, with the other end attached to
building ground. The connector must be crimped with the proper tool, allowing it to be
connected to both ground screws on the enclosure. Before crimping the ground wire into
the provided ground lug, ensure that the bare copper wire has been cleaned and
antioxidant is applied to the bare wire. In addition, anti-rotation devices or lock washers
must be used with all screw connections for the grounding wire.
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:
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.
