Chassis warning
•
Before connecting or disconnecting ground or power wires to the chassis,
ensure that power is removed from the DC circuit.
•
To prevent personal injury or damage to the chassis, lift the unit only by
using handles that are an integral part of the chassis, or by holding the
chassis underneath its lower edge.
•
Any instructions in this guide that require opening the chassis or removing a
board should be performed by qualified service personnel only.
•
Slots and openings in the chassis are provided for ventilation. Do not block
them. Leave the back of the frame clear for air exhaust cooling and to
allow room for cabling - a minimum of 6 inches (15.24 cm) of clearance is
recommended.
Electric shock warning
•
This unit might have more than one power cord. To reduce the risk of
electric shock, disconnect the two power supply cords before servicing the
unit.
•
Before working on a chassis or working near power supplies, unplug the
power cord on AC units.
•
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
•
This unit is grounded through the power cord grounding conductor. To avoid
electric shock, plug the power cord into a properly wired receptacle before
connecting the product input or outputs.
•
Route power cords and other cables so that they are not likely to be
damaged. Disconnect power input to unit before cleaning. Do not use liquid
or aerosol cleaners; use only a damp cloth to clean chassis.
•
Dangerous voltages exist at several points in this product. To avoid personal
injury, do not touch exposed connections and components while power
is on. Do not insert anything into either of the system's two power supply
cavities with power connected
•
Never install an AC power module and a DC power module in the same
chassis.
•
Do not wear hand jewelry or watch when troubleshooting high current
circuits, such as the power supplies.
•
To avoid fire hazard, use only the specified correct type voltage and current
ratings as referenced in the appropriate parts list for this unit. Always refer
fuse replacement to qualified service personnel.
•
This unit relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC,
15A U.S. (240 VAC, 10A international) is used on the phase conductors (all
current-carrying conductors).
•
To avoid electrocution ensure that the rack has been correctly grounded
before switching on the unit. When removing the unit remove the grounding
connection only after the unit is switched off and unplugged.
