Figure 3: DS3/2DS3 I/O Card Location on the Cisco 6160 Chassis Backplane

Wire-Wrap Pins

There are 30 wire-wrap pins located on the right side of each DS3/2DS3 I/O card that support

Central office alarm relay interfaces (visual and audible) between the NI-2 card and the subscriber.
BITS clock input circuits.
Wire wrap and socket type connections. A six-pin connector, Molex 26-03-3061, can be used to mate with each of the five headers.

Note The relay for the circuit-breaker trip alarm is wired through the small green terminal blocks on the rear of the chassis, not through the wire-wrap connector.

Both the alarm relays and the BITS clock connections are optional. If you connect the alarm relays, they transmit critical, major, and minor alarms to a separate, external alarm device. The alarm device uses a bell, light, or some other signal to alert service personnel to the change in system status. If you connect the BITS interface, the Cisco 6160 can receive a clock signal from a T1 line.

One of the alarm relay functions provided by the wire-wrap connector is an alarm cutoff (ACO) circuit that you can wire to your external alarm device. To use this feature, connect the alarm device so that it can close the contact between pin 5 and pin 6 in row P4.

The connector also provides contacts for the following features, all of which can be used (or not used) separately:

Audible alarms—Wire pins whose signals begin with AUD
Visible alarms—Wire pins whose signals begin with VIS
Power alarms—Wire pins whose signals begin with PEM
BITS clock—Wire pins whose signals begin with RX_BITS

Note There is one set of contacts for audible alarms and one set for visual alarms. You can use either or both sets of contacts.

You can wire the alarm relay contacts as normally open (NO) or normally closed (NC); however, the ACO circuit can be wired as NO only. Use common (CO) pins for both the NO and NC wiring methods.

Wiring Method	Pins to Use
Normally open	Pin 2 in rows P1, P2, P3 (NO) Pin 5 in rows P1, P2, P3, P4 (NO) Pin 1 in rows P1, P2, P3 (CO) Pin 4 in rows P1, P2, P3 (CO) Pin 6 in row P4 (GND¹)
Normally closed	Pin 3 in rows P1, P2, P3 (NC) Pin 6 in rows P1, P2, P3 (NC) Pin 1 in rows P1, P2, P3 (CO) Pin 4 in rows P1, P2, P3 (CO)

General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following are examples of recommended installation and replacement practices:

Do not force the card into the chassis backplane connectors P3 and P9. This action can damage the pins on the connectors if they are not aligned properly with the I/O card.
Ensure that the card is straight and parallel to the chassis backplane when you install it onto the connectors. The pins on the connectors can be damaged if the card is not installed correctly.
Firmly press on the card to ensure that the connectors mate with the chassis correctly.

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

Hot Swapping Cards

The DS3/2DS3 I/O card is not hot swappable. Removing the DS3/2DS3 I/O card will interrupt service for the entire system until the card is replaced.

Caution The DS3/2DS3 I/O card must be installed and removed by a trained technician only.

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 when you handle any card or component.

Follow these guidelines to prevent ESD damage:

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 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 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.

Removing and Installing the DS3/2DS3 I/O Card

The following sections describe how to remove or install a DS3/2DS3 I/O card.

Caution Static voltages as low as 30 volts can cause latent damage to circuitry on the I/O card. Observe all standard antistatic procedures (for example, wear a ground strap).

Removing the DS3/2DS3 I/O Card

Complete the following steps to remove the DS3/2DS3 I/O card from the chassis backplane:

Caution To prevent the system from powering up, do not install the fuses at this time. If the fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses after the system is installed and connected.

Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the companies inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions might not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure, for their own protection, that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
