This publication describes how to upgrade and replace the Flash EPROM memory card in a

Cisco 4000 router. Read this entire publication before upgrading your system.

Note This document only applies to the original Cisco 4000 router, later routers in the Cisco 4000

series do not have a Flash EPROM memory card.

What is Included in the Flash EPROM Memory Card Upgrade Kit

The Flash EPROM memory card upgrade kit includes the following components:

•An updated Flash EPROM memory card that supports 8 or 16 MB of Flash memory.

•Updated boot ROMs that provide support for the new Flash EPROM memory card.

Safety Recommendations

Warning To ensure your safety and the safety of others, be sure the power is OFF and the power

cord is unplugged before working on the router.

Caution To avoid damaging ESD-sensitive components, ensure that you have discharged all static

electricity from your body before opening the chassis. Before performing procedures described in

this publication, review the following sections: “Safety Recommendations,” “Safety with

Electricity,” and “Tools and Equipment Required.”

Safety with Electricity

Follow these guidelines to ensure general safety:

•Keep the chassis area clear and dust-free during and after installation.

•Put the removed chassis cover in a safe place.

•Keep tools away from walk areas where you or others could fall over them.

•Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll

up your sleeves.

•Wear safety glasses when working under any conditions that might be hazardous to your eyes.

•Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

Safety with 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 can weld to the terminals.

Follow these guidelines when working on equipment powered by electricity:

•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.

•Before working on the system, turn OFF the power and unplug the power cord.

•Disconnect all power before doing the following:

—Installing or removing a router chassis

—Working near power supplies

—Performing a software upgrade

•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 system.

—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.

Tools and Equipment Required

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.AlwaysfollowESDpreventionprocedureswhenremovingandreplacingcards.Ensurethat

the router 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 chassis frame surface 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

within the range of 1 through 10 megohm (Mohms).

Tools and Equipment Required

You need the following tools and equipment to replace the Flash EPROM memory card in the

Cisco 4000.

•ESD cord and wrist strap

•Screwdrivers, Number 1 and Number 2 Phillips

•ROM extraction tool or ﬂat-bladed screwdriver

Accessing the Internal Components of the Router

To access the internal components of the router, you must remove the component tray.

Warning Hazardous voltages may exist in or near the power supply, so use extreme caution when

working near the power supply. Before starting any of these procedures, turn OFF power to the

system, unplug the power cord, disconnect any cables at the ports, and connect your ESD-preventive

wrist strap.

Removing the Component Tray Procedure

Some Cisco 4000 routers have a safety latch tab on the chassis that affects removing the component

tray. (See Figure 1 and Figure 2.)

If you have a chassis with a safety latch tab, follow the procedure in the following section

“Removing the Component Tray from a Chassis with a Safety Latch”.

If you have a chassis without a safety latch tab, follow the procedure in the section “Removing the

Component Tray from a Chassis without a Safety Latch” later in this document.

Replacing Boot ROMs

Figure 4 Flash EPROM Card and Connector—Side View

To reinstall the Flash EPROM card, see the section “Replacing Boot ROMs.”

Replacing Boot ROMs

If your Cisco 4000 router does not have boot ROMs more recent than Cisco Internetwork Operating

System (Cisco IOS) Release 10.2(8), you will need to upgrade them with the boot ROMs provided

with the Flash EPROM card. To upgrade the boot read-only memory (ROM) software to a new

software image, the existing boot ROMs must be replaced.

Step 1 Open the chassis and expose the boot ROMs following the procedures in the section

“Accessing the Internal Components of the Router.”

Step 2 After the boot ROMs (FW1 and FW2) on the system card are exposed (see Figure 5),

follow the procedures in this section to replace the ROMs.

Caution The correct placement of the boot ROMs is crucial. If improperly positioned, the new

components could be damaged when the system is powered on. Read through all of the instructions

before proceeding. To prevent damage to the ROMs from ESD (when handling the system and its

components), follow the ESD procedures described earlier. Also, be careful not to damage or scratch

the printed circuit card under the ROMs.

Step 3 Locate the boot ROMs, FW1 and FW2. (See Figure 5.)

Figure 5 Boot ROMs Locations and Boot ROMs Capacity Jumpers

Step 4 Using an EPROM extraction tool or a small ﬂat-blade screwdriver, gently remove the boot

ROMs and set them aside.

Installing the Flash EPROM Card

Step 5 Insert the new boot ROMs in their respective sockets in the orientation shown in

Figure 5 being careful not to bend or crush any of the bottom pins. To straighten out a bent

pin, use needlenose pliers. Align the notch in the new ROM with the notch in the ROM

socket, ignoring the orientation of the label.

Step 6 Boot ROMs version Cisco IOS Release10.2(8) and higher require setting the boot ROM

capacity jumpers, J5 and J6, to the 8 Mb boot ROMs position. (See Figure 5.) To set the

boot ROM capacity jumpers to the 8M boot ROMs position, short pins 2 and 3 on J5 and

J6, as shown in Figure 5.

Installing the Flash EPROM Card

Follow these steps to install the Flash EPROM card.

Caution To prevent damaging the Flash EPROM card, handle it only by the sides.

Step 1 Slip on an ESD wrist strap, ensuring that it makes good skin contact. Connect the

equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact

with the connectors.

Step 2 Line up the Flash EPROM card with the 96-pin connector (see Figure 4) and screw holes.

Step 3 Holding the Flash EPROM card by its edges, push straight down on the connector (see

Figure 4) to insert its connector into the socket on the component tray. (See Figure 3.)

Caution Be gentle; do not over torque the screws. The maximum screw torque is 7 inch-lb (about

what is required to turn a key in an automobile’s door lock).

Step 4 Reinstall the two card-mounting screws. (See Figure 3.)

Step 5 Proceed to the section “Replacing the Component Tray.”

Replacing the Component Tray

Follow these steps to replace the component tray in the chassis shell:

Step 1 Reinsert the component tray into the shell, pushing on the back of the tray while at the same

time pressing on the chassis release screw (as shown in Figure 1 and Figure 2) with the

thumb of your right hand.

Step 2 Retighten the chassis release screw.
