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



Warning Ultimate disposal of this product should be handled according to all national laws and regulations.



Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.



Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use common connectors. Use caution when connecting cables.



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



Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.


Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:


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.


Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Disconnect all power before doing the following:

Installing or removing a Cisco IAD2420 chassis

Working near power supplies

Removing the cover from a Cisco IAD2420 chassis

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the chassis.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).


Caution To avoid damaging electrostatic discharge (ESD)-sensitive components, ensure that you have discharged all static electricity from your body before opening the chassis.

Required Tools and Equipment

You need the following tools and equipment to remove and install memory modules in a Cisco IAD:

Medium-size flat-blade screwdriver (1/4 inch [60 to 70 mm])

Size M 3.5 (metric) hex-head nut driver (optional)

ESD-preventive wrist strap

ESD-preventive antistatic bag


Memory and Software Upgrade Tasks

If you upgrade your Cisco IOS software to a later release, it may be necessary to increase the size of Flash memory.

For memory module installation instructions, see the applicable procedure as follows:

Flash memory SIMM—"Replacing System-Code Flash Memory" section

Cisco IOS Image—"Installing a Cisco IOS Image in Flash Memory" section

Figure 1 shows the physical locations of the replaceable memory components.

Figure 1 Memory Locations in Cisco IAD2420 Series IADs

Replacing System-Code Flash Memory

The system code (software) is stored on a Flash memory SIMM. It might be necessary to increase the system-code Flash memory if you are upgrading to software with more features.

The show version command allows you to see the amount of system-code Flash memory in KB. The following example shows a system with 8 MB of system-code Flash memory. The amount of system-code Flash memory (8192 KB) is shown on the next to last line of this example.

256K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (INTEL28F016)

Configuration register is 0x100

System-Code Flash Memory Configurations

Cisco IAD2420 series IADs contain one Flash memory SIMM socket that holds a single 8-, 16-, or 32-MB Flash memory SIMM. Flash memory of 8, 16, or 32 MB may be required, depending on the size of the Cisco IOS software image.

To load two simultaneous images of software, at least 16 or 32 MB of Flash memory may be required, depending on the image size. To increase Flash memory capacity, you must remove the existing Flash memory SIMM and install a SIMM of the required capacity.


Note Flash memory SIMMs for the Cisco IAD2420 series IAD are available only from Cisco. An unapproved Flash memory SIMM can damage the Cisco IAD. Contact a customer service representative for more information. See the "Obtaining Technical Assistance" section.


Table 1 lists the available Flash memory SIMMs. Order system-code memory from Cisco Systems.

Replacing the Flash Memory SIMM


Caution To prevent damage to the Flash memory SIMM from ESD, follow the ESD procedures described in the "Preventing Electrostatic Discharge Damage" section.


Step 1 (Optional) Cisco recommends backing up the Cisco IOS image and the stored configuration on an external device such as a PC or TFTP server. The Cisco IOS commands for backing up and restoring the data are described in the Configuration Fundamentals Configuration Guide for Cisco IOS Release 12.1 or 12.2.


Caution The Cisco IOS image resides in Flash memory. The Cisco IOS image (or a new one) will have to be downloaded into the new Flash memory SIMM.


Tips If you are going to download a new Cisco IOS image, ping the address where the image is located, before you turn off power to the chassis, to make sure that the new image can be reached.


Step 2 Open the chassis by following the procedures and warnings in the "Opening the Chassis" section.

Step 3 Turn the chassis so that the SIMMs are closest to you and the ports are facing away from you. See Figure 1 to identify the Flash memory SIMM location in your Cisco IAD2420 series IAD.

Step 4 Release the latches holding the Flash memory SIMM by squeezing them outward as shown in Figure 2. Be careful not to break the holders on the connector.


Caution To prevent damage, do not push or pull on the center of the Flash memory SIMM. Handle the Flash memory SIMM carefully.

Figure 2 Releasing Latches on a Flash Memory SIMM

Step 5 With the chassis still oriented as described in Step 3, hold the Flash memory SIMM with the polarization notch to the right. (See Figure 2.)


Caution To prevent damage, note that some Flash memory SIMMs have the components mounted on both surfaces; therefore, when inserting the Flash memory SIMM, always use the polarization notch as a reference and not the position of the components on the Flash memory SIMM.

Step 6 Insert the Flash memory SIMM into its socket at an angle of approximately 45 degrees to the main circuit board. Gently tilt the Flash memory SIMM down until both latches snap into place.

Step 7 Close the chassis, connect a console terminal, and turn ON the power using the procedures in the "Closing the Chassis" section.

If error messages relating to memory are displayed, repeat Step 2 through Step 7, taking care to seat the Flash memory SIMM firmly in its socket.

Step 8 Download the previous or new Cisco IOS image into the new Flash memory SIMM. To copy a Cisco IOS image from a TFTP server to the Flash memory, see the "Installing a Cisco IOS Image in Flash Memory" section.


Installing a Cisco IOS Image in Flash Memory

Follow this procedure to copy a Cisco IOS image from a TFTP server to the Cisco IAD2420 series IAD Flash memory if the Flash memory SIMM does not have an installed Cisco IOS image.

If your system already has a Cisco IOS image in Flash memory, follow the procedure in the "Copy an Image from a TFTP Server to a Flash Memory File System" section of the appropriate Configuration Fundamentals Configuration Guide, for Cisco IOS Release 12.1 or 12.2.

Opening the Chassis

This section explains how to open the chassis by removing the chassis cover.


Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.



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



Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.


Refer to Parts A and B in Figure 3 and follow these steps to remove the chassis cover:


Step 1 Turn OFF power to the chassis, but to channel ESD voltages to ground, do not unplug the power cable.


Warning Before working on a system that has an on/off switch, turn OFF the power.


Step 2 Attach an ESD-preventive wrist strap.

Step 3 Disconnect all interface cables from the rear panel.

Step 4 Turn the unit upside down so that the top of the chassis is resting on a flat surface and the front of the chassis is facing you. (See Figure 3, Part A.)

Step 5 Remove the single screw located on the bottom of the chassis (on the chassis side closest to you).

Step 6 If necessary, insert a medium flat-blade screwdriver into the slots shown in Figure 3, Part A, and gently rotate the blade so that the top and bottom sections separate slightly.

Step 7 Holding the chassis with both hands, position it as shown in Figure 3, Part B.

Step 8 Gently pull the top section away from the bottom section. (See Figure 3, Part B.) The fit is very snug. It might be necessary to work the chassis sections apart at one end and then the other until the top section is removed from the bottom section.

Figure 3 Chassis Cover Removal—Parts A (Top) and B (Bottom)

Closing the Chassis

This section describes how to close the chassis by installing the cover.


Step 1 Position the two chassis sections as shown in Figure 4.

Step 2 Press the two chassis sections together:

Top section tabs (see A) fit into bottom section.

Bottom section tabs (see B) fit into top section.


Caution To fit the two sections together, it might be necessary to work them together at one end and then the other, working back and forth; use care to prevent bending of the chassis edges.

Figure 4 Installing the Chassis Cover

Step 3 When the two sections fit together snugly, turn the chassis so that the bottom is facing up, with the front panel toward you.

Step 4 Replace the cover screw. The recommended screw torque is 8 to 9 in.-lb (0.90 to 1.02 N·m).

Step 5 Reinstall the chassis on the wall, rack, desktop, or table.

Step 6 Reconnect all cables, and connect a console terminal, if required.

Step 7 Turn ON power to the chassis.

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.
