a supervisor engine 720 behaves indifferently. when booted up it shows below results in monitor.

boot doesnt help with anything and has it back to monitor.

IOS used to load is s72033-jk9o3sv-mz.122-18.SXD7b.bin

rommon 1 > dir bootflash:

Initializing ATA monitor library...

my knowhow points me to invalid image. can i use an external flash, load the image into it & then transfer it to device. is it that simple or complex to be done or any specific way to achieve this.

can xmodem be used , if so how ?

appreciate if experts can point to the simplest way out.

Thanks in advance.

Hi,

Yes, there can be issues if sup720 does not understand the file system on the PCMCIA card as it was formatted on a different machine. In such scenarios "unable to read magic number" error message will be thrown.

However, in most of the cases I have not seen this issue crop up.

Hi,

Simplest way is to use an external PCMCIA card having a compatible image in the supervisor's disk0: slot and do the following:

dir disk0:

check the image name

boot disk0:

Unfortunately xmodem is not supported on sup720.

Hope this helps,

Shashank

does pcmcia cards have compatibility issue with different model chasis. if the card is used on another switch to have the proper ios on card  & then transferred to the sup 720. any problems that might crop up?

thanks.
