Jon,

Thank you for your reply, this is the first time we are using either slot 5 or slot 6 in this chassis, never been used before. Actually the SUP was configured in a 6506 E class chassis,would this be the same?

If it is infact an issue with the slot 5 or 6 as we tested in both with same bad result, is there any diagnostics we can do to be sure this is the root cause?

This is the original configuration on the chassis

Slot 1 WS-X6K-SUP1A-2GE

Slot 2 Empty

Slot 3 WS-X6416-GBIC

Slot 4 WS-X6348-RJ-45

Slot 5 Empty

Slot 6 Empty

Slot 7 Empty

Slot 8 Empty

Slot 9 Empty

Thanks

John

"Actually the SUP was configured in a 6506 E class chassis,would this be the same?"

Should not make a difference. You can run diagnostics on 6500 but i'm not sure it will show you. What you could do is try a moving your WS-X6348-RJ-45 module into slot 5 while running with the Sup1A and see if it comes online.

Jon

Jon,

I will try that, which reminds me is it possible to try the Sup 720 in any other slots besides 5 or 6? I know specs say that these are teh slots to use, but what about slot 1 or 2 which I know are working with current configuration.

Thanks,

John

No i'm afraid with the 6509 it is slots 5 & 6. This is because these slots provide a connection to the switch fabric for the supervisor. This is why the SFM (Switch Fabric Module), which is a module you could use with a Sup2 to provide connections to the switch fabric, always went in slots 5 & 6.

Jon

Jon,

So just to get a heads up if the

WS-X6348-RJ-45 comes online in slot 5 then I can assume there is no issue with the slot and can concentrate on the sup720 issue?

Thanks for your assistance,

John

John

Not necessarily. What i was trying to prove was whether the slot is actually totally unuseable and any module would not work in it.

Bear in mind that the issue could be with the switch fabric connection which hasn't been an issue for you in your 6509 before as you has a Sup1A.

If your supervisors work in the E chassis in slots 5 & 6 then it would definitely point to a problem with your chassis. This is just an extra check you can do.

Jon

Thanks Jon for all this information,

On the case of the backplane, is it possible that the Sup1A can work normally in Slot 1 and the backplane at slot 5 and 6 are faulty, is the backplane all one connection aside from the switch fabric connection (Can the SFModule be replaced by itself?)What I'm looking at is what ever could be causing the problem in the chassis, for the Sup720 is there more than the backplane that would have to be swapped out, or is it something like the SFM seperate and replacable?

There are 2 backplanes in the 6500 chassis. One is a 32Gbps shared bus between all modules. This is what the Sup1A will connect into and also what your other modules will use as it is the supervisor that provides the second backplane which is a high speed switching fabric for modules that can connect into them ie. fabric enabled and fabric only modules.

So the switch fabric ie non 32Gbps shared bus is provided by either

1) SFM (Switch Fabric Module)

2) Supervisor with inbuilt switch fabric connectivity ie. the Sup720. I don't believe the SFM functionality of the Sup720 is a separate part of the module but i could be wrong.

I can't fully answer your question to be honest. I suspect there are some good internal Cisco only docs that have the detail you need. Attached is a link to a 6500 Architecture Paper which goes into a fair bit of detail.

I would still suspect the chassis if your Sup 720s work in the E chassis.

Jon Thanks for your help, I will let you know how things get on.
