Redundant 4506 supervisor

I have "inherited" a Catalyst 4506 with IOS version 12.2(20)EWA1 and Supervisor IV already installed.  We recently purchased a second Supervisor IV and I am looking to install this second supervisor for redundancy.  Is there anything special with installing a second supervisor or so I just physically install the new supervisor and the IOS will automatically set everything up?  I've been searching and I can't really find any documents about how to do this.  Thanks!

Hi!

You need have an identical  IOS on both Supervisor (and identical hardware)

.

Supervisor engine redundancy is configured by default, but You can manually synchronized configuration as next:

Switch(config)# redundancy

Switch(config-red)# main-cpu

Switch(config-r-mc)# auto-sync standard

Switch(config-r-mc)# end

Switch# copy running-config startup-config

You can read more information on this doc

Dear ed ,

        what is your switch model its 4506 or 4507 , if it 4506 it wont support for supervisor redudancy , because it has got only one supervisor slot , slot no 1

kindly look into below link for switch chasis comparison
