Dear friends..............
I have a problem with my switch 2950. While the switch loading the IOS, it shows { Error loading "flash:/ c2950-i9-mz.121-11r.EA1.bin"
Interrupt within 5 seconds to abort boot process. Boot process failed...}. Then I typed the command boot it shows the same problem.I have a new IOS with me. I wish to install this one. But I do not get the usemode or configuration mode. My friend, I hope you can help me by giving the correct step of installation using tftp or not

Is this what you get ?

Error loading ""

Interrupt within 5 seconds to abort boot process.
Boot process failed...
switch:

I suppose the IOS is either corrupt or unavailable in the flash..
See this Cisco article: h..p://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a0080094955.shtml

From Cisco documentation:

At the switch: prompt, enter the flash_init command to initialize the flash file system:

switch: flash_init

Enter the copy xmodem boot loader command to start the transfer.
switch: copy xmodem: flash:image_filename
When the XMODEM request appears, use the appropriate command on the terminal-emulation software to start the transfer and copy the software image into Flash memory.
h..p://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/c2900sa4/ol013501.htm#xtocid163012

when it says "Begin the Xmodem or Xmodem-1K transfer now" - In your Hyperterminal session, you need to click on the Transfer drop down menu. Click on Send File and a dialog box will open. Select XModem in the Protocol drop down and browse for the IOS image on your PC. Click send and the IOS image will be sent to the switch.

Thanks a lot dear friend,
I did that.But it shows......

switch: copy xmodem flash:c2950-i6q4l2-mz.121-9.EA1.bin
xmodem: permission denied
Oly get permission denied. What should I do to make it permission allowed?

[The Dirizhor]

Is this happening ?

switch:
switch: flash_init
Initializing Flash...
...The flash is already initialized.
switch: load_helper
switch: boot
Loading ""...: permission denied

Error loading ""

Interrupt within 5 seconds to abort boot process.
Boot process failed...
switch:

then, read the previous post and do that... Let me explain

Step1: At the switch: prompt, enter the flash_init command to initialize the flash file system:

 switch: flash_init

Step2: Enter the copy xmodem boot loader command to start the transfer.

switch: copy xmodem: flash:image_filename

Step3: When the XMODEM request appears, "Begin the Xmodem or Xmodem-1K transfer now" - In your Hyperterminal session, you need to click on the Transfer drop down menu. Click on Send File and a dialog box will open. Select XModem in the Protocol drop down and browse for the IOS image on your PC. Click send and the IOS image will be sent to the switch.

Hope this helps

hey dudes!

i'm having the same problem, but as i start the xmodem transfer about 1 min later, it comes out the prompt "error limit exceeded"

how do i solve this problem?

[talent pk]

Read the Cisco TAC section. There are lots of useful informations already posted for Router/Switch Boot process problems.

Hi!

I've had the same problems with my Cisco Catalyst WS-C3524-XL-EN.

I used the same procedure with gcomm in Ubuntu Linux. I actually used a Live CD, and configured my switch.

I got the same error with "

switch: copy xmodem flash:c3500xl-c3h2s-tar.120-5.WC17.bin
xmodem: permission denied

Or just an "unknown command -> copy" error.

I just wrote "test" instead of "c3500xl-c3h2s-tar.120-5.WC17.bin" and now it's transfering... Slow... but it seems to be working.

Guess I will have to rename afterwards...


Will update on my progress.

Hi guys,

I have a similar problem, all I do I connect my switch 3550 through a console cable to my computer, then I do not see any progress just message:

Transferring c3550-i5k2l2q3-mz.121-22.EA1.bin...

however there is no message about transfer rate..

please clarify it ???

Well, it helped on my switch, I just renamed it back after transfering it. I didn't get any transfer rate etc. But as it's 9600BAUD, it's 9600bits pr. second, and about 1,2KB pr. second.

Did you manage to upload and fix your switch?
