Upgrading the IOS on a WS-C3524-XL


I have a 3524 running IOS Version 12.0(5.4)WC(1)

This won't support the Gbic modules ws-g5483 so i want to upgrade the IOS.

I've downloaded the IOS file c3500xl-c3h2s-mz.120-5.WC5 so i intend to upload this via hyperterminal & the xmodem command after i have erased the flash & rebooted the switch

this is really the first time i've done this so iwas hoping to get some advice on what to expect or at least prepare for in case of any problems

Is this the best way or should i put the file into the root of my tftp server & use a copy tftp flash?

all help/comments greatly appreciated

Re: Upgrading the IOS on a WS-C3524-XL

I suggest to use tftp only (faster to upload)

1.Check for the present IOS file (show flash:), and free space.

2.Take back up of the file to TFTP (copy flash:IOSFILE tftp:)

3.Delete the existing IOS file

4.Check for the free space(If the file does not get delete permanatly, use "Squeez flash:" )

5.Upload the new IOS using (copy tftp: flash:)

6.Reboot Switch, have console connected to monitor connected to just make sure every thing goes well.

7.Incase any problem use manual boot(using BOOT TFTP:oldIOS) to boot the swtich.

8.Fall back to the oldone.
