Chapter 2 Preparing for Installation
Site Requirements
Warning This unit is intended for installation in restricted access areas. A restricted access area can be
accessed only through the use of a special tool, lock and key, or other means of security.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning Read the installation instructions before connecting the system to the power source.
Warning This product requires short-circuit (overcurrent) protection, to be provided as part of the building
installation. Install only in accordance with national and local wiring regulations.
Site Requirements
This section provides site power requirements for the Cisco 7600 series routers. You should verify the
site power prior to installing the router. Power requirements vary for each router; ensure that you verify
the site power for the type of router you are installing.
For EMI recommendations, refer to the Site Preparation and Safety Guide.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
• Connect the equipment end of the strap to an unfinished chassis surface.
• When installing a component, use any available ejector levers or captive installation screws
toproperly seat the bus connectors in the backplane or midplane. These devices prevent
accidentalremoval, provide proper grounding for the system, and help to ensure that bus connectors
areproperly seated.
• When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.
• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
• Place a removed component board-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
