Cisco 2960X unable to boot

Brand new switch that somehow lost it's image. When I turn the switch on, it goes to the switch: prompt and I am unable to do anything. When I run the boot command, it gives me an error stating "error loading "flash:/c2960............"  No such file or directory.  How do I get this switch to boot up using a default image. I can't get to the enable prompt to upload a new image. When I try and do the "enable" I recieve "unknown cmd: en"

Thanks.

If I understand you may want to reset it to factory defaults.  You can then load your OS and config via tftp.  

To reload:

To reset the switch:

  • Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds.
  • Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch reboots.

The switch now operates like an unconfigured switch. You can enter the switch IP information by using Express Setup.

What is the output of the command

dir

You either have no image in your flash memory or it is not being selected by the boot command.

Throwing packets since 2012


switch: dir

List of filesystems currently registered:

                  bs[1]: (read-only)

               flash[9]: (read-write)

              xmodem[10]: (read-only)

                null[11]: (read-write)

                tftp[12]: (read-only)

If you issue the command 

dir flash:

what files does it show?

It only shows the following:

switch: dir flash:

Directory of flash:/

    2  -rwx  109       <date>               info

    3  drwx  512       <date>               update

  139  -rwx  676       <date>               vlan.dat

  140  -rwx  9548      <date>               config.text

I'm in the process of following these steps to transfer a new .bin file over. http://www.cisco.com/c/en/us/support/docs/switches/catalyst-2950-series-switches/41845-192.html

How does one transfer the .bin if they do not have HyperTerminal? The instructions I linked above were for HyperTerminal, which isn't on Windows 7. All I have is putty

  • Issue the copy xmodem: flash:filename command on the switch.

    Here is an example:

    switch: copy xmodem: flash:c2955-i6q4l2-mz.121-13.EA1.bin
    Begin the Xmodem or Xmodem-1K transfer now...
    CCC
  • From the top of the HyperTerminal window, choose Transfer > Send File.

Ryan,

Since this is a 2960X, you should be able to copy the ios image from a usb flash drive to flash. This will be far faster than waiting on an xmodem copy.

Ok that would be great. But are there instructions? I just did the xmodem transfer and it completed but then it stated I/O Error and the .bin file is not in the flash dir. So I need to do this again. If you could tell me how to do it via a USB drive, that would be great.

Load the binary file onto a USB flash drive that is less than 8Gb in size and plug it into either of the USB ports on the front of the switch (left one is usbflash0:, right one is usbflash1:) 

! at the switch: prompt enter the command -->

copy usbflash0:name_of_image.bin flash:name_of_image.bin 

! or

copy usbflash1:name_of_image.bin flash:name_of_image.bin 

! once the copy is complete tell the switch to boot

boot

I was able to finally get this working using hyperterminal (hilgraeve) at 115200 baud rate. Thx again for the help and ideas!

I find xmodem to be very time consuming, hence the below:
 
Setup your tftp server.
Place your 2960X image on tftp.
Plug cable into Management (Interface FastEthernet0) port and apply below:
 
set IP_ADDR 10.0.0.98/255.255.255.0
 
set DEFAULT_ROUTER 10.0.0.5
 
ping 10.0.0.5
 
BOOT=tftp://10.0.0.5/c2960x-universalk9-mz.152-7.E4.bin
 

boot tftp://10.0.0.5/c2960x-universalk9-mz.****.bin

 

NB*

 

To avoid the below, do the following

 

set

 

BOOT=tftp://10.0.0.5/c2960x-universalk9-mz.152-7.E4.bin


The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable
image.

 

Would you like to enter the initial configuration dialog? [yes/no]: n
