Note For procedures that explain how to use the ﬂash disk PC card, refer to the Using the Flash

Disk document that accompanies every Flash Disk shipped from the factory.

Installation Prerequisites

This section provides hardware and software requirements, and a list of parts and tools you need to

remove main, Flash, and ROM monitor memory in the Cisco 7200 series routers and the

Cisco uBR7200 series routers. This section also includes safety and ESD-prevention guidelines to

help you avoid injury to yourself and damage to the equipment.

Parts and Tools

You need the following tools and parts to replace the main, Flash, and ROM monitor memory in the

network processing engine and the I/O controller. If you need additional equipment, contact a

service representative for ordering information:

• New DRAM or Flash SIMMs, SDRAM DIMMs, boot ROM, ﬂash disk PC cards or Flash

memory cards

• Number 2 Phillips and a 3/16-inch, ﬂat-blade screwdriver

• An 8-mm wrench or nut driver, or adjustable wrench (for connecting a grounding lug to a

Cisco uBR7200 series DC-input power supply)

• A 7-mm wrench or nut driver, or adjustable wrench (for connecting the DC-input power lead

strain-relief cover to a DC-input power supply)

• Tape (for securing the switch handle of a DC circuit breaker in the OFF position)

• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all

upgrade kits, FRUs, and spares

• An antistatic mat or surface, or static-shielding bag

• Small needlenose pliers

If your router is mounted in a 4-post or telco rack, make sure you have at least one other person

available to assist you with removing the chassis from the rack.

In addition, replacing the boot ROM on the I/O controller requires a DIP-type integrated circuit (IC)

removal tool (see Figure 8) or a small ﬂat-blade screwdriver. Replacing the boot ROM on the

NPE-200 or the NPE-300 requires a PLCC-type IC extractor tool (see Figure 9).
