If you reboot the unit during the upgrade or after a failure, the boot process appears similar to this:

Problem Description:  System ID: 0009E8D2698E

The menu that displays after the boot process is the VxWorks bootloader, which is functionally equivalent to
ROM monitor (ROMmon) in Cisco IOS Software. Neither of the full operating systems is loaded or available,
so neither of the full command sets is available.

Note: If the VxWorks bootloader has been upgraded to Cisco IOS Software ROMmon but Flash memory has
no operating system available, the unit displays the 

ap:

 prompt. In order to recover from this condition, refer

to the Using the MODE button section in the Troubleshooting chapter of the Configuration Guide.

Use these steps to restart the conversion process and get the unit back up:

If there is an 802.11a radio module installed (AIR−RM20A), remove it during the rest of this
procedure.

1. 

Verify that the connection settings in the terminal application are 9600−8−None−1 and NO flow
control (not hardware or software).

2. 

Format the Flash memory for the unit to accept the VxWorks upgrade image:

Press Ctrl−Z in order to bring up the hidden

 menu.

a. 

Press exclamation point (!, Shift−1) in order to choose

.

b. 

Press 3 in order to choose Flash memory.

Note:  3 is usually the choice for Flash memory. But you may have to enter a different
number, which depends on your setup.

c. 

Press Y (Shift−y) in order to confirm the decision to reformat the Flash memory.
