Cisco 6015 I/O Module FRU Installation and Replacement Notes

This document provides an overview of and installation and replacement procedures for the Cisco 6015 Input/Output (I/O) module. The I/O module is a field-replaceable unit (FRU) and can be used in both a commercial and outside-plant environment.

Note The I/O module does not function when you use an OC-3c/OC-3c NI-2 card in the Cisco 6015; however, an I/O module must be installed in the chassis for the system to operate correctly. The OC-3c/OC-3c NI-2 card does not support the DS3, E1, or T1 interfaces found on the front of the I/O modules. Therefore, the trunk and subtending interfaces are provided on the front of the OC-3c/OC-3c NI-2 card.

The OC-3c/OC-3c NI-2 card can be used only in a commercial environment and does not work in an outside-plant environment. Either I/O module can be used in conjunction with the OC-3c/OC-3c NI-2 card.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

This document includes the following sections:

General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following examples list the recommended installation and replacement practices for the Cisco 6015 system modules.

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

Do not force the module into its slot. This action can damage the pins on the backplane if they are improperly aligned with the module.
Ensure that the module is straight and not at an angle when you install the module in the slot. Installing the module at an angle can damage the module. Use the guide rails to install the module correctly.

Hot Swapping Modules

The I/O module is a FRU; however, it is not hot swappable. If you remove the I/O module, service is interrupted for the entire system until you replace the I/O module.

Caution Only a trained technician should install and remove the I/O module.

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.

Tip Use the ESD grounding jack on the fan module for all maintenance except when you remove the fan module. Use the ESD grounding jack on the DC PEM when you remove the fan module.

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 grounding jack. There are two ESD grounding jacks that are located on the following Cisco 6015 chassis modules:

Fan module
DC PEM

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.

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

Removing and Installing the I/O Module

The following sections describe how to remove or install an I/O module.

Removing the I/O Module

Note If you use AC power and the power cord is plugged into the wall outlet, unplug it.

If you use DC power and the fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses after you install and connect the system.

Cisco does not provide the fuse and alarm panel.

TimeSaver We recommend that you label each data cable at both ends to identify its destination.

Complete the following steps to remove the I/O module from the Cisco 6015 chassis:

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:

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.
