The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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:
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. After you complete the module replacement procedures, install the chassis cover as described in the "Installing the Chassis Cover" section.
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
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
Cisco IAD2801 series integrated access devices have a cover that slides off the rear of the chassis.
To 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.
Figure B-1 Removing the Cisco IAD2801 Chassis Screws
Step 3 Insert a flat-blade screwdriver between the chassis and chassis cover at the screwdriver pry points on the bottom of the chassis, indicated in Figure B-2. Rotate the screwdriver 90 degrees to disengage the chassis cover from the chassis. It may be necessary to turn the unit upside down on a flat surface to access the pry points.
Figure B-2 Screwdriver Pry Points
Step 4 Gently slide the chassis cover of the router away from the bottom of the chassis, as shown in Figure B-3.

Step 5 Place the router bottom on an antistatic mat, and begin installing modules.
Figure B-4 shows the locations of the DIMMs, PVDMs, and power supply in the Cisco IAD2801.
Note Advanced integration modules (AIM) are not supported on the Cisco IAD2801.

To install the main power supply in a Cisco IAD2801, remove the chassis cover as described in the "Removing the Chassis Cover" section, and perform the procedure in the "Installing the Main Power Supply in a Cisco IAD2801" section.
To 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.

Cisco IAD2801 series integrated access devices have a cover that slides onto the chassis from the rear of the chassis. For cover installation procedures, see the "Installing the Cover on Cisco IAD2801 Series Integrated Access Devices" section.
To install the chassis cover on a Cisco IAD2801, follow these steps:
Step 1 Slide the top cover of the router back on the bottom of the chassis by pushing it in the direction opposite than shown in Figure B-3, "Removing the Cisco IAD2801 Chassis Cover."
Step 2 Replace the three screws and the ground connection that you removed when you opened the chassis. See Figure B-1, "Removing the Cisco IAD2801 Chassis Cover."
