Cisco 4507 IOS Installation for Supervisor Engine IV


Recently we purchased Cisco IOS Enhanced L3 SW (OSPF, IGRP) for

Supervisor IV engine.

CD itself is nothing but a single .bin file (cat4000-is-mz.121-12c.EW1.bin)

I just wanted to make sure before I make any progress.

I have Cisco 4507R chasis with two Sup IVs and one X48 10/100/1000 module.

My qeustions are;

1. How do I install this IOS? copy tftp: flash:filename.bin?

2. Do I need to install this to each Sup IV engine?

3. Anything else need to be done after installing IOS?

Thank you very much for your help in advance.

You can find upgrade procedures at

You'll need a TFTP server and you can get one at

Yes. You'll need to install this on both Supervisors.

Actually this is brand new hardware and we're not upgrading IOS.

Does each supervisor Engine IV has its basic IOS installed?

Otherwise how could I enter priviledge mode to each sup IV engine?
