P P E N D I X B Installing and Upgrading Internal Modules

This document describes how to install or upgrade modules that are located internally within your Cisco IAD2801 series integrated access devices, such as memory modules, packet voice data modules (PVDMs), and power supplies. You need to remove the cover from the router to install or remove any of these items. The document contains the following sections:

• Safety Warnings, page B-1

• Removing the Chassis Cover, page B-2

• Locating Modules, page B-4

• Replacing the Power Supply, page B-5

• Installing the Chassis Cover, page B-6

Before you perform any of these module replacement procedures, disconnect the power and remove the cover, as described in the “Removing the Chassis Cover” section on page B-2. After you complete the module replacement procedures, install the chassis cover as described in the “Installing the Chassis Cover” section on page B-6.

Safety Warnings

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. Statement 1

Warning Read the installation instructions before connecting the system to the power source. Statement 1004

Appendix B Installing and Upgrading Internal Modules Removing the Chassis Cover

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026

Removing the Chassis CoverCisco IAD2801 series integrated access devices have a cover that slides off the rear of the chassis.

Removing the Cover from Cisco IAD2801 Series Integrated Access DevicesTo remove the cover from a Cisco IAD2801, follow these steps:

Step 1 Make sure that the router is turned off and is disconnected from the power supply.

Warning Before opening the unit, disconnect the telephone-network cables to avoid contact with telephone-network voltages. Statement 1041

Step 2 Use a Phillips screwdriver to remove the ground connection screw. Use a flat-blade screwdriver or a hex driver to remove the three screws that hold the chassis and the chassis cover together, as shown in Figure B-1.

Appendix B Installing and Upgrading Internal Modules Replacing the Power Supply

Replacing the Power SupplyTo install the main power supply in a Cisco IAD2801, remove the chassis cover as described in the “Removing the Chassis Cover” section on page B-2, and perform the procedure in the “Installing the Main Power Supply in a Cisco IAD2801” section on page B-5.

Caution To comply with Telcordia NEBS GR-1089-Core and EN 300386 requirements, you must use foil twisted-pair cable that is properly grounded at both ends.

Installing the Main Power Supply in a Cisco IAD2801To replace the main power supply in a Cisco IAD2801, perform the following steps. See Figure B-4 for the locations of connectors and other components within the Cisco IAD2801.

Step 1 Disconnect the power supply cable from the main power supply connector.

Step 2 Remove the screws that fasten the main power supply to the chassis. See Figure B-5.
