Maybe I am the worst network engineer in the world or maybe I am unlucky.
Recently, I made an upgrade on some of 6509 switches. I bought totally new 6509-E system including chassis, fan, power, and some new line cards. I also insert my fiber line cards that I used in old 6509 with supervisor 2.
Everything was fine until I checked the status of the modules with the “show module” command. The switch was up, new line cards were functioning, but my old WS-X6516-GBIC’s were in PwrDown state. When I checked the switch logs I found
00:02:31: %C6KPWR-SP-4-UNSUPPORTED: unsupported module in slot 2, power not allowed: The image for the card is not bundled in image.
What does it mean? I had a recent IOS and it does not support this card. I was not surprised because it happened to me before. I just checked the software advisor tool from Cisco and found another version.I tried it, but it did not work out.
A wise friend of mine told me that I should give a try to a safe harbor image. I was not aware of the safe harbor program until that time. Safe harbor images are tested images. They are stable, interoperable and solid. It was my last chance before I should have to escalate this problem.
I found out that there are some problems between Supervisor Engine 720 and WS-X6516-GBIC, but the problem was only valid for 5.0 to 5.3 Hw versions and I had 5.7. It should not be my problem but text mentioned DFC Sub-modules. I focused on the DFC daughter card then. Everything became clear when I found “Catalyst 6500 Series DFC, DFC3A, DFC3B, and DFC3BXL Installation Note” document. I saw a note mentioned below
Note You cannot have a DFC in a system with a Supervisor Engine 720
I removed one DFC (WS-F6K-DFC) from one of the WS-X6516-GBIC and finally, it started to work. I also changed the IOS images to safe harbor ones. I spent days to solve this problem and this turned out to be a simple issue for which I got the answer instantaneously from the web!
