Catalyst 4506 satarting at rommon1>

Level 1

Hi there,

I have 2 nwe cat4506 and both with the same symptoms:

After switching them up they enter in rommon mode and we are unable to bypass. We have checked and changed confreg value to 0x2102 or even 0x2142 but the resul it's the same described above.

Seems that any special booting option has been set at factory since the following outpout is displayed

WARNING:

Offline mode is locked, this is a POST only image

Please reboot without the "-o" option.

Press enter to reset...

after pressing enter box enters in rommon1>

Any suggestion ??

Looks like you have somekind of diag image which is normally used by our development. Issue a "dir bootflash" to check this. If you have a diag image, delete it and squeeze bootflash

I have already done it and the output is:

File size Checksum File name

4779752 bytes (0x48eee8) 0x7292926 cat4000-k8.7-6-1.bin

And nothing else.

This is the image ordered for box.

In the other hand, if we have to delete this image could you give us intructions to download a new one, we have tried throuhg the 10/100 console port with a TFTP at the other side without success. Output was:

boot -v cat4000-k8.7-6-1.bin

boot: bootstring is: "cat4000-k8.7-6-1.bin"

35:01.538619: Loading file 10.1.1.1:cat4000-k8.7-6-1.bin

35:01.708357: Download failed: Could not open requested file for reading

Network download of "cat4000-k8.7-6-1.bin" failed

loadprog: error - on file open

boot: cannot load "cat4000-k8.7-6-1.bin"

boot failed.

Since you have "cat4000-k8.7-6-1.bin" in bootflash, boot from rommon using "boot bootflash:cat4000-k8.7-6-1.bin". Once the switch comes up, format the bootflash and TFTP a different good file(7.6(5) is the latest in 7.6

Working now,

we have modified "boot bootflash:cat4000-k8.7-6-1.bin" now is "boot bootflash: " the squeezed bootflash, and... Switch finally started

Thnx 4 your help
