Chapter 2 Preparing for Installation
Site Requirements
Note In installations where FXS modules are installed, supplemental grounding is required.
Note Always ensure that all of the modules are completely installed and that the captive installation screws
are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These
practices are normal installation practices and must be followed in all installations.
Caution Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in
new cable runs) to a suitable and safe earth ground before connecting them to the module.
Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines:
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected from a circuit; always check the circuit before working on
it.
• Look carefully for possible hazards in your work area, such as damp floors, ungrounded power
extension cables, frayed or damaged power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
– Use extreme caution; do not become a victim yourself.
– Disconnect power from the system.
– If possible, send another person to get medical aid. Otherwise assess the condition of the victim,
and then call for help.
– Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
• Use the product within its marked electrical ratings and product usage instructions.
• Install the product in compliance with local and national electrical codes.
• If any of the following conditions occur, contact the Cisco Technical Assistance Center:
– The power cable or plug is damaged.
– An object has fallen into the product.
– The product has been exposed to water or other liquids.
– The product has been dropped or shows signs of damage.
– The product does not operate correctly when you follow the operating instructions.
• Use the correct external power source. Operate the product only from the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult the Cisco Technical Assistance Center or a local electrician.
