Check your GBIC module. eg. LX ( long distance)or SX( short distance ).
I think they should be SX.

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.
