Cisco 6260 Quad-Port Flexi ATU-C to Octal-Port DMT ATU-C Line Card Conversion Procedures

OL-0991-01

General Safety Precautions and Maintenance Guidelines

• Ensure that the line card is straight and not at an angle when you install the line card in the slot.

Installing the line card at an angle can damage the line card.

• Fully depress the ejector tabs to ensure that the line card connector mates with the backplane

correctly. Firmly seat the line card in the slot.

Caution Any line card that is only partially connected to the backplane can disrupt system operation.

Hot Swapping Cards

The line cards support hot swapping. Hot swapping allows you to remove, replace, and rearrange the line

cards without disconnecting the system power. When the system detects that a line card is added or

removed, it automatically runs diagnostic and discovery routines, and acknowledges the presence or

absence of the line card.

If an unprovisioned line card is installed for the first time, the system identifies it as present but

unprovisioned. Instructions for provisioning the line card are found in the “Provision the Octal-Port

xTU-C Line Cards” section on page 15, as well as the in the appropriate software guide for the

Cisco 6260 chassis.

Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur

when electronic cards or components are improperly handled, results in complete or intermittent

failures. Use an antistatic strap during handling.

Follow these guidelines to prevent ESD damage:

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

• Connect the equipment end of the strap to the ESD jack on the front of the Cisco 6260 chassis

card cage.

• 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.

• Avoid touching the printed circuit boards or connectors on the NI-2 cards or line cards.

• 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.

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

between 1 and 10 megohms.
