Upgrading Memory in Cisco 4000 Series Routers 29

Installing the Flash EPROM Card (Cisco 4000 Router Only)

Step 3 Align the notch in the new ROM with the notch in the socket, ignoring the orientation of

the label. Insert the ROM in its socket, being careful not to bend any pins. To straighten

a bent pin, use needlenose pliers.

Caution The notch on the ROM must match the notch on the socket. Installing the ROM backward

will damage it.

Step 4 For Cisco 4000 routers only, set jumpers J5 and J6 to designate the capacity of the Boot

ROMs. For boot ROMs version Cisco IOS Release10.2(8) and higher short pins 2 and 3

on both jumper locations, J5 and J6 as shown in the 8 MB boot ROMs position. To short

pins 2 and 3 on J5 and J6, install the jumper block over the two pins located away from

the Flash EPROM card, as shown in the 8 MB boot ROMs position on Figure 24. For 4

MB boot ROMs, which are prior to version 10.2(8), install the jumper on the upper two

pins at J6 and the lower two pins at J5.

Installing the Flash EPROM Card (Cisco 4000 Router Only)

If you removed the Flash EPROM card from a Cisco 4000 router to gain access to main memory, or

to replace the card with an upgraded one, follow these steps to install the old or replacement card:

Step 1 Line up the card with the 96-pin socket and screw holes. (See Figure 8.)

Step 2 Holding the card horizontally by its edges, insert it into the socket by pushing straight

down, being careful not to bend the pins.

Step 3 Using a Number 1 Phillips screwdriver, reinstall the two card-mounting screws.

Caution Do not overtorque the screw. The card or the underlying motherboard could be damaged.

The maximum screw torque is 7 inch-lb.

Step 4 After you upgrade the Flash EPROM card, install the new boot ROMs included in the kit

(part number MEM-4000-8F=) and set jumpers J5 and J6 using Step 1 through Step 4 in

the previous procedure (page 28).
