Replacing the Boot ROMs in the Cisco 2500 Series and AccessPro PC Card Routers 7

Replacing the Boot ROMs—All Models

The procedure for replacing the boot ROMs is the same for all Cisco 2500 series and AccessPro PC

card routers. To replace the boot ROM software with a new software image, you must remove the

existing boot ROMs and replace them with new boot ROMs.

Tools and Equipment Required for Replacing the Boot ROMs

The following tools and equipment are required to replace the boot ROMs:

• Plastic leaded chip carrier (PLCC) extraction tool

• Two boot ROMs

Replacing the Boot ROMs

To replace the boot ROMs, follow these steps:

Step 1 Locate your router model number in Table 1 and see the corresponding ﬁgure for the

location of the boot ROMs (labeled FW1 and FW2) on the system card. (If you have a

Cisco 2517, 2518, or 2519 router/hub, the boot ROMs are located on the router card.) Then

proceed to Step 2 on page 17.

Caution The correct placement of the boot ROMs is crucial. If the ROMs are installed in the wrong

sockets they could be damaged when the system is powered ON. To prevent damage to the ROMs

from ESD (when handling the system and its components), follow the ESD procedures described

earlier in the section “Preventing Electrostatic Discharge Damage.” Also, be careful not to damage

or scratch the printed circuit card under the ROMs.
