12.2SG/1 support on Cat4000 SupIV

[snpatel]

We have a Cat4006 chassis (WS-C4006) with SupIV (WS-X4515) currently running 12.2(26)EWA9.

An upgrade to 12.2(46)SG1 failed with a message similar to "Unsupported chassis type 24, system can not boot"

I couldn't find a link stating support strategy for the 4006 chassis. Is that particular switch limited to EWA code?

Don't see a link either , may have to run it by cisco. I know SG was brought out to support the 4506-E chassis so it may not support the old 4006 chassis .

12.2(37)SG is the last IOS release supporting cat4006 Chassis

It has been End of software maintenance since May 3, 2006 and would be obsolete by May 3, 2009.

So now, its time to consider hardware upgrades.
