Follow these guidelines to prevent ESD damage:

•

Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1

Caution

and 10 megohms.

Removing and Installing the DSL Interface Module

The following sections describe how to remove or install a DSL interface module.

Proper ESD protection is required whenever you handle Cisco equipment. Installation and

maintenance personnel should be properly grounded by means of grounding straps to eliminate the

risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever it is removed

from the chassis.

Always use an ESD ankle or wrist strap and ensure that the wrist strap makes good skin contact.

Connect the equipment end of the strap to the ESD grounding jack. There are two ESD grounding

jacks that are located on the following Cisco 6015 chassis modules:

Fan module

When you install a component, use 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 ensure that bus connectors are properly seated.

When you remove a component, use available ejector levers or captive installation screws to release

the bus connectors from the backplane or midplane.

Handle the modules by the extraction handles 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 protects components

from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
