Cisco router doesn't boot the system

Dear colleagues,

I've met the following problem with my Cisco 7201 router:

The router doesn't boot IOS.

There're four leds (ALARM, PWR OK, STATUS, CF ACTV) where:

*ALARM is Solid Red  which means "On if Cisco IOS has crashed, and a reset has happened, and remains on until Cisco IOS is reloaded."

*PWR OK is Solid Green which means "The power-on is successful and the system is attempting to boot software, or has booted software."

*STATUS is Blinking Amber which means "ROMmon is loading."

*CF ACTV is Off which means "No activity"

* - The information/description gathered from http://www.cisco.com/en/US/docs/routers/7200/install_and_upgrade/7201_install_config/11364ov.html

The IOS image is on CF card, so as it shows "No activity" and "ROMmon is loading", the IOS hasn't booted yet and the boot process perhaps stucked in ROMmon.

I am not able entering ROMMON via console or AUX ports to boot the system manually. Because Non of ports (Console, AUX) doesn't show me anything at any baud rates (1200 - 115200) not even the BootLoader or Bootstrap process.

As you can see, the last configuration of terminals was particularly default:

line con 0

logging synchronous

transport output all

stopbits 1

line aux 0

stopbits 1

line vty 0 4

session-timeout 15

access-class 1 in

logging synchronous

transport input ssh

transport output all

At first I thought that RS232 chips on board were burned because of statical electricity. But how's it possible to burn all RS232 chips for Console and AUX ports at the same time?

As usual, the SMARTnet has been expired and I am not able to use RMA.

People, maybe you already met such problem with any Cisco equipment and you know the solution? Please, any suggestions?

Best regards,

Andrey

You should be able to connect the console as 9600 baud 8-none-1.

This should show you what is happening at the bootup. If not you have a broke device.

The rommon ios is on the device not the cf card.

Navypop42, thnx for the reply.

You should be able to connect the console as 9600 baud 8-none-1.

     > Yes. I know that by default the baud rate is 9600 etc. It was the first baud rate I tried to use to connect to router via console port.

This should show you what is happening at the bootup. If not you have a broke device.

     > Yes it should. But the terminal (PUTTY) shows nothing but the black screen

The rommon ios is on the device not the cf card.

     > Yes. I know that the rommon image is on the device not in CF. On CF I meaned the IOS XXXXX.bin file.

Hi,

Yes, I've solved the problem.

The problem was because of RAM (DDR2 1GB ECC)

I've purchased the server RAM with equal characteristics and everything is working fine.

Thanks you for your answer.

I thinks, it DDR-SDRAM DIMM and no DDR2.

Did you remember where you've purchased memory ?

Thanks,

Hi.

You're right, I meaned DDR1 not DDR2.

I live and work in Uzbekistan. I've purchased it in local store.

You're able to purchase it localy too or from online stores like ebay or amazon.

Good luck.

Best regards,

The main requirement is you need to purchase DDR equal to characteristics.
