10 1200-Watt AC-Input Power Supply Replacement Instructions
Installation Safety, ESD Precautions, and Tools Required
Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Safety with Electricity
You can remove or install a redundant (second) power supply without turning off the other supply.
Before removing a redundant power supply, ensure that the first supply is powered on to ensure
uninterrupted operation.
Follow these basic guidelines when working with any electrical equipment:
Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis.
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
In addition, use the guidelines that follow when working with any equipment that is connected to
telephone wiring or other network cabling:
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected
at the network interface.
Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are
handled improperly, can result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin
contact.
When removing or installing a power supply, connect the equipment end of a ground strap to the
chassis ground screw on the interface processor end of the chassis, or to an unpainted surface
inside the noninterface processor end of the chassis, such as the chassis frame.
If you are returning a replaced part to the factory, immediately place it in a static shielding bag
to avoid ESD damage to the board.
