This chapter describes the general equipment, safety, and site preparation requirements for installing the 6T3 line card. This chapter contains the following sections:
You need the following tools and parts to install a line card. If you need additional equipment, contact a service representative for ordering information.
6T3 line card
T3 SMB interface cables
Number 2 Phillips screwdriver
Your own electrostatic discharge (ESD)-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares
Antistatic mat
Antistatic container
Attenuator kit (optional)
Software and Hardware Requirements
Table 2-1 lists the recommended minimum Cisco IOS software release required to use the 6-port 6T3 line card in the 7304 router platform.
Table 2-1 6T3 Line Card Software Requirements
Router Platform
Recommended Minimum Cisco IOS Release
Cisco 7304 Router1
Cisco IOS Release 12.1(10)EX or a later release of Cisco IOS Release 12.1 EX
1The 6T3 line card requires a Network Services Engine 100 (NSE-100) to operate.
75-Ohm In-Line Coaxial Attenuator (Optional)
A 75-ohm in-line coaxial attenuator may be required to tune the signal between the 6T3 line card and the far-end equipment if the line card is experiencing line code violations (LCVs). LCVs occur when the far-end equipment transmit signal saturates the front-end receiver of the 6T3 line card.
Cisco offers an attenuator kit (ATTEN-KIT-PA=) that contains five attenuators with fixed values ranging from 3 dB to 20 dB. For more information on the attenuator kit, go to the following URL:
This section provides safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Caution The 6T3 line card is not intended for direct connection to outside telecommunication lines. If connected to an outside telecommunication line, suitable protection devices need to be provided.

Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
Before beginning any procedure 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 when potentially hazardous conditions exist.
Never assume that power has been 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.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
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 has been 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 cards or components are improperly handled, results in complete or intermittent failures. Line cards 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 to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly 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 board component-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 protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).
