1941 problem with ESW and ESG

[MattNaidar]

Hi Forums,

I have an issue that I'm hoping someone can shed a little light on.

I have a 1941 with recent version 15.2-2T IOS happily working with a HWIC-4ESG (4 port Gig) card located in slot 1. When I add a HWIC-4ESW (4 port 100Mb/s) in slot0, then the gig card in slot 1 is no longer seen - it just dissappears (almost as though it's using the same memory location which I believe it is).

I've tried swapping them over. It seems as though whatever is in slot 0 takes preference. They both work on their own, in either slot, but only on their own. When they are in there together, only the switch card in slot 0 works.

I will try upgrading tomorrow to see if this helps.

Has anyone seen this before or can assist?

I've gone through bug toolkit, couldn't find anything about it.

Thanking you in advance.

Cheers,

Matt

Rather than wait for tomorrow, I've upgraded and done further tests tonight.

Then you turn it off, unplug the ESW, and the ESG re-appears!

To reply a third time to myself!, normally the gig switchcard is located in slot 1 and an ATM card in slot 0, both fully functional at the same time - never had an issue. I got off ATM today and needed a couple of extra ports. So it really does seem that when 2 switch cards of differing speeds are used similtaneously.

I should mention this is mixing EHWIC with HWIC.

I've found out that the 4 and 9 port HWIC switchport cards don't with EHWICs. :(
