We have recently observed a strange problem with Copper 1000BaseT SFPs in a WS-X6724-SFP line card within a 7606 chassis. All copper SFPs stopped working but and ports did not show connected (and the status LEDs were not lit) but the opposite end of the link saw the connection as 'up' (these we just point-to-point GigE links between GigE SFPs and GigE ports on a WS-X6748-GE-TX line card in another chassis. Fibre SFPs still remained operational. The only change made was the insertion of some 10GE optics (-SR and -LR) into two 8-port 10GE line cards in the 7606 chassis which shouldn't have had any effect. The 7606 is running 12.2(33)SRD4 Advanced IP Services. The WS-X6724-SFP has not be reset as we are awaiting a suitable maintenance window, and would prefer not to reset it if there's an alternative solution. Has anything similar been seen before?
