Power off the PCM output switch and the power to the associated two power trays prior to removing a
power tray.
Note
The following guidelines are for your safety and to protect equipment. The guidelines do not include all
hazards. Be alert.
•
Never attempt to lift an object that might be too heavy for you to lift by yourself.
•
Keep the work area clear and dust-free during and after installation. Do not allow dirt or debris to enter
into any laser-based components.
•
Keep tools and FCC components away from walk areas.
•
Do not wear loose clothing, jewelry, and other items that could get caught in the FCC while working
with the FCC and its components.
•
Use Cisco equipment in accordance with its specifications and product-usage instructions.
•
Do not work alone if potentially hazardous conditions exist.
•
Make sure your installation follows national and local electrical codes:
◦
In the United States, National Fire Protection Association (NFPA) 70, United States National
Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1.
◦
In other countries, International Electrotechnical Commission (IEC) 60364, part 1 through part 7.
•
Connect only a DC power source that follows the safety extra-low voltage (SELV) requirements in
UL/CSA/IEC/EN 60950-1 and AS/NZS 60590 to the DC input power system.
•
Make sure that you have a readily accessible two-poled disconnect device incorporated in the fixed
configuration wiring of a DC input power system.
•
Make sure that you provide short-circuit (overcurrent) protection as part of the building installation.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly
handled, results in complete or intermittent failures. We recommend use of an ESD-preventive wrist strap
whenever you handle network equipment or one of its components.
To prevent ESD damage:
•
Always use an ESD-preventive wrist or ankle strap, and ensure that it makes good skin contact. Connect
the equipment end of the connection cord to an ESD jack or a bare metal surface on the FCC (ensure
that the FCC is grounded).
•
Handle a card by its ejector levers, when applicable, or its metal carrier only; avoid touching the board
or connector pins.
•
Place a removed card board side up on an antistatic surface or in a static-shielding bag. If you plan to
return the component to the factory, immediately place it in a static-shielding bag.
•
Avoid contact between a card and clothing. The wrist strap protects the board from only ESD voltage
on the body; ESD voltage on clothing can still cause damage.
