    I will try swapping Flash memory first and RAM afterwards, if the Flash swap doesn't work. I do have good Flash and RAM from another working Cisco 3660. I'll post the results later on.
    Thanks for the links.

The router starts and finish POST then decompress image file from flash memory then shows this message: System Bootstrap, Version 12.3(8r)T8, RELEASE SOFTWARE (fc1) Technical Support:...


I don't really know what your asking but i guess you want to know why your startup-config doesn't load. What your router is displaying is normal. You need to change the configuration register.
1.Let the router load then if asked select Yes to abandon autoinstall, then select No to skip initial setup. Press return (enter button) when asked.
2. Now type the following at the prompts. (you type the bold stuff press enter after each command)
router>enable
router#conf t
router(config)#config-register 0x2102
router(config)#exit
router#reload
........save changes blah blah blah.. type NO
continue with reload Yes
providing you have a startup-config, the router will now load it on bootup.

Hope this helps

I can help you with the IOS you need, but Cisco does not list 12.3.x XC, they only have YZ, YG, XR, XK, XG for this router. Email me at thrca@thrca.com for more help.

''!!! WARNING: The switch is not usable !!!''


Unfortunately the show stack isn't showing any results other than it is either a hardware or software fault. I am guessing it is a fault with the hardware as the show version in your first post states "interface Ethernet-controller 4 failed POST POST error status : general error occured".

Ethernet-controller 4 is one if the gigabit ports (poss fibre port), so if you have anything attached to those, disconnect and reboot the switch and see what happens. If that doesn't work, you could try reinstalling the IOS, but at a guess I would say its a hardware fault.

Hi all. Now i'm lose IOS of cisco 2691. help me! and give me how to load IOS to Cisco 2691 by tftp. thanks alot


Recovering Cisco IOS Software imagesIf your Cisco router experiences difficulties and no longer contains avalid Cisco IOS software image in flash memory, you can download a newCisco IOS image using one of the following ROM monitor commands:
blank.gifxmodem—(AllCisco 2600 series routers) Use this command to copy a Cisco IOS imagefrom the console, if the computer attached to your console has aterminal emulator with Xmodem capability. See the "Copying an Image from the Console Using the xmodem Command" procedure.
note.gif Note blank.gifDownloadinga Cisco IOS image from a console is very slow. This procedure should beused only in an emergency and is not recommended for normal Cisco IOSimage upgrades.

For the fastest possible download from a console, set the console speed to 115200 bps by using the confreg ROM monitor command. See the "Configuration Register Commands" procedure.
blank.giftftpdnld—(ExceptCisco 2691) Use this command to copy a Cisco IOS image from a TFTPserver that is accessible through the FastEthernet 0/0, Ethernet 0/0,or Token Ring 0/0 port. See the "Copying an Image from a TFTP Server Using the tftpdnld Command" procedure.
note.gif Note blank.gifThetftpdnld command is not available on the Cisco 2691 router. Therecommended method for installing a Cisco IOS image on a Cisco 2691router is from a CompactFlash memory card loaded in the externalCompactFlash memory card slot. See the "Entering Boot Commands" procedure.

Bootup Router and then nothing


Hi,
Your router is in the wrong mode. You need to change this by changing the conf-register to 0x2102

at the rommon prompt type in

config-reg 0x2102

reboot

If there are any errors you can get the correct syntax by typing ? at the rommon prompt the line number will go up on every line.

The way to get into rommon mode is by pressing the break key from Hyperterminal as the router is rebooting. So make sure you don't do this by accident. If you do just reboot by power cycling.

Your Startup Config should be unchanged, but you need to be very careful what you do in rommon mode it is easy to blat stuff.

Any changes you make once you get into the command (enable) mode should be saved by
copy running-config startup-config

Any problems just let me know.

good feed back would be much appreciated.

Boot Loop


you may have to reload the OS of the router.
i dont suppose you can kick it into romon mode can you? (usually done by hitting the pause break button on boot.)

if you can you should be able to use Xmodem to reload the OS (as long as you have a copy of it located on your computer)
