Cisco 6160 I/O Card
Installation and Configuration

This document describes the procedures you should follow to replace the input/output (I/O) card on the Cisco 6160 digital subscriber line access multiplexer (DSLAM) with NI-2. Currently, the Cisco 6160 supports the NI-2 card but not the NI-1 card.

The Cisco 6160 NI-2 DSLAM is a member of the Cisco 6000 DSL product family that provides end-to-end service by handling voice or data traffic, or both, between a subscriber home or office, a telephone central office (CO) facility, and various networks.

This document includes the following sections:

Note Before you replace an I/O card, refer to the "Safety Guidelines" section.

Product Description

Cisco Systems currently offers one type of I/O card for the Cisco 6160. The I/O card:

Is initially installed on the backplane of the Cisco 6160 by a Cisco Systems specialist before it is shipped.
Is electrically mated with dedicated backplane connectors.
Provides relays and wire wrap pins for dedicated central office (CO) facility alarms operated by Cisco IOS software.
Provides wire wrap pins for redundant building-integrated timing source (BITS) clock inputs.

A single I/O card connects to 1 DS3 or 1 OC-3c trunk and 2 DS3 subtend ports. A multi-rack, multi-chassis arrangement allows for expansion to 12 subtend ports.

Warning A metal EMI cover is permanently installed over the I/O card to protect against radiated EMI emissions during operation. The EMI cover should be installed at all times during normal operation.

Parts and Tools

Have the following tools available before you begin:

ESD-preventive equipment or the disposable grounding wrist strap included with the I/O card
Small Phillips-head screwdriver

Working with Electrical Equipment

Follow these guidelines when you work with any electrical equipment:

Before you begin 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, and 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.

Wiring Outside the Central Office

Use the following guidelines when you work with 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 noninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when you install or modify 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. Use an antistatic strap during handling.

Follow these guidelines to prevent 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 the ESD jack on the front left side of the chassis.
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 to 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 I/O cards by edges 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.

Caution Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1 and 10 megohms.
