Channelized and Electrical Interface Line Card Installation and Configuration

78-16417-02

Preparing for Installation

• 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.

• Do not wear loose clothing, jewelry, or other items that could get caught in the router while working

with line cards.

• Cisco equipment operates safely when it is used in accordance with its specifications and product

usage instructions.

See the “Line Card Interface Cables” section on page 25 for information on interface cables.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are

improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI)

shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap

whenever you are handling network equipment or one of its components.

The following are guidelines for preventing 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 connection socket on the router or to

bare metal on the chassis.

• Handle channelized and electrical interface line cards by the captive installation screws, the

provided handle, ejector levers, or the line card metal carrier only; avoid touching the board or

connector pins.

• Place removed channelized and electrical interface line cards 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 the channelized and electrical interface line cards and clothing. The wrist

strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still

cause damage.

Warning

For safety, periodically check the resistance value of the ESD strap. The measurement should be

between 1 and 10 megohms.

Required Tools and Equipment

You need the following tools and parts to remove and install channelized and electrical interface line

cards:

• Flat-blade or Phillips screwdriver

• ESD-preventive wrist or ankle strap and instructions

• Interface cables to connect the channelized and electrical interface line card with another router or

switch
