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 1 20 VAC,
1 5A 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.
Electrostatic Discharge (ESD) Caution
Follow static precaution at all times when handling this unit.

Always wear an ESD-preventive wrist or ankle strap when handling

electronic components. Connect one end of the strap to an ESD jack or
an unpainted metal component on the system
Handle cards by the faceplates and edges only; avoid touching the

printed circuit board and connector pins.
Place any removed component on an antistatic surface or in a static

shielding bag.
Avoid contact between the cards and clothing.

Periodically check the resistance value of the antistatic strap.

Recommended value is between 1 and 10 mega-ohms (Mohms).
