This might not help at all, but here it is anyway.
I have the same setup, except that I am using GigaStack modules and a
GigaStack cable. This is working without any problems.
I am not an expert in fiber cables, but I would suggest that you check that
GigaBit interfaces and make sure they're not disabled, they are using the
same encapsulation, and they are set for auto in duplex and speed.
Hth,
Ole

Subject: Connecting Two 3548XL's with GigaEthernet [7:9098]
I recently accquired two 3548XL's I want to connect both via giga
ethernet. The problem I'm facing is that the link light will go up on one,
but not on the other. I had the TX/RX ports reversed ie RX going to the TX
on the other switch and vice versa. I configured both 0/1 modules with no
negoiation auto, and duplex full. When I bring an interface up say on
3548XL-A and 3548XL-B, the A comes up, the B comes up but goes down right
away. The link light stays up on the 3548XLA. When I switch the cables
around (multi mode fiber) the opposite happens. IE. B interace comes up,
and A goes down. I can't provide configs right now, but I will in a few
hours (I'm not at home right now). I've tried different fiber cables and
no go. I know for a fact they work. If anyone who has this type of config
or knows how I should tackle it could drop me a line, I would appreciate
it.
