Cisco 1142N AP - Upgrade gone really wrong

Unanswered Question
Jan 24th, 2012

Hi everyone,

I have run into a major issue with an autonomous Cisco 1142AP. We were in the midst of a firmware upgrade when something went wrong and caused the AP to reboot in an error mode. Basically the unit was flashing Blue, amber, red. We unmounted the unit from the wall, connected to the console, and it would now only flash red over and over.

We pulled out the cisco guides and performed a factory reset on the unit. This still does not work. and the contents of our flash directory is empty. All we get is a ROMMON AP prompt on the unit. If I issue a set command, I can see the default settings for IP, netmask, etc.

I cannot access the unit via the network, even after setting IP info and matching it up to my laptop. Since I have no network connectivity, I can't TFTP a new IOS file to the unit.

I am stumped. Any ideas how to get the config as if it was out of the box, or an alternate way to TFTP to the unit?

Here is a summary of what I get when I factory reset:

using  eeprom values

WRDTR,CLKTR: 0x87000800 0x40000000

RQDC ,RFDC : 0x80000035 0x00000209

using ÿÿÿÿ ddr static values from serial eeprom

ddr init done

IOS Bootloader - Starting system.

DDR values used from system serial eeprom.

Waiting for PHY auto negotiation to complete... TIMEOUT !

Ethernet link is down.

The system has encountered an error initializing

the Ethernet port.

The system is ignoring the error and continuing to boot.

If you abort the system boot process, the following

commands will re-initialize Ethernet, TFTP, and finish

loading the operating system software:

    ether_init

    tftp_init

    boot

button is pressed, wait for button to be released...

button pressed for 69 seconds

process_config_recovery: set IP address and config to default 10.0.0.1

process_config_recovery: image recovery

I then run a set command

ap: set

DEFAULT_ROUTER=10.0.0.1

ENABLE_BREAK=yes

IP_ADDR=10.0.0.1

MANUAL_BOOT=no

NETMASK=255.255.255.224

PRODUCT_MODEL_NUMBER=AIR-LAP1142N-A-K9

RELOAD_REASON=58

ROM_PERSISTENT_UTC=1326908306

TERMLINES=0

TFTP_SERVER=10.1.70.250

ip_ADDR=

tftp=

ap:

Notice the lines in red, I must have typed someting incorrectly. How do I remove this?

PS: Now once the unit boots after being reset, I cannot even type in the CLI. Someting majorly screwed up here.

Can the bootstrap be reinitialized?

I have this problem too.

Hi,

Unfortunately I had followed that portion of the procedure but I was unsuccessful. Unfortunately I could not connect to the unit at all.

What bothers me now is I cannot type anything in the CLI after I boot up, either normally, by interupting the boot, or by performing a reset.

Edit: I am now able to type in the CLI, but there is also kinds of bizarro information when I run the set command. Is there a way to clean up this set config? Also, is there any other mechanism to transfer the IOS image other than TFTP. Like I said, I can't connect to the unit via network, only console.
